OSMAC BaseOSMAC Base User Manual Page 4 1 Installation 1.1 Environment The OSMAC BaseOSMAC Base is designed for an indoor office environment. Ambient air temperature should be between -10 and +40C, and relative humidity in the 20-80% range. Operation outside of this range may cause damage to the unit. 1.2 Licensing This product operates in the commercial two-way radio communications band. A license to operate on a particular frequency must be obtained from the FCC. Use form 600 to apply for a license to operate this unit in your area. Operation of this product must be in compliance with the applicable FCC rules and regulations. In most cases, the FCC Rules and Regulations are covered in Title 47 of the CFR, part 90 pr Part 22. Form 600 is available at the FCC WEB site: http://www.fcc.gov/formpage.html. See appendix A for a list of frequency coordinating agencies. This product is Certified for use under FCC Parts 22 and 90. Internal circuitry may not be modified. Modification of circuitry within this unit may void your authority to operate the equipment. 1.3 Radio Communication Interference The OSMAC BaseOSMAC Base generates and uses high-frequency radio energy which can cause interference if not installed in accordance to the user manual and using sound radio system engineering practice. For best results, it is recommended that a qualified radio service technician install and configure the OSMAC BaseOSMAC Base. The OSMAC BaseOSMAC Base has been tested and found to comply with the limits for a Class A computing device pursuant to Part 15 of the FCC Rules and Regulations. Operation of this device in a residential area is likely to cause interference in which case the user must, at his own expense, be required to take whatever measures may be required to correct the interference. 1.4 Locating the OSMAC Base The OSMAC BaseOSMAC Base is designed to sit on a desktop. Although this is a good location for ease of operation, it is usually not the best place to locate the antenna. For most installations, it is recommended that the antenna be located away from the unit, and high enough to provide good coverage. "Base Station" type antennas will provide much better coverage than will the "rubber duck" type antennas. This is particularly true if an external keyboard is to be used, since many keyboards malfunction in the presence of strong RF fields. The LCD's contrast may be adjusted through a small hole in the rear of the unit. If the LCD is difficult to read adjust its contrast with a small flat-bladed screwdriver. 1.5 Unit Setup a) Connect the antenna or antenna cable to the BNC jack on the rear of the unit. b) If you are using the OSMAC BaseOSMAC Base with a computer system, connect the computer's RS-232 port to the lower serial port on the rear of the unit. c) If you are using an external keyboard, connect it to the PS-2 keyboard jack at the rear of the unit. d) If the telephone interface will be used, connect a telephone line to the RJ-11 jack on the rear of the unit. e) Connect the DC power supply to the OSMAC BaseOSMAC Base. It connects to the large DIN connector on the rear. Plug the external DC supply into an AC wall socket. Turn the power to the unit ON. f) Configure the unit if necessary using the Configuration Mode.

OSMAC BaseOSMAC Base User Manual Page 5 2 Local Operation 2.1 Overview The OSMAC BaseOSMAC Base is a desk top system that provides paging and wireless two-way communications. With an Intel 32 bit processor at its core, and 4 megabytes of FLASH memory, the OSMAC BaseOSMAC Base can handle the wireless communications needs of the small office or a large plant. OSMAC BaseOSMAC Base features: ð Stand-alone operation with built-in keypad and LCD display. ð Two built-in RS-232 serial ports for advanced paging applications. ð Built-in telephone interface for remote access. ð Internal two-way radio for monitoring the channel and two-way voice communication. ð POCSAG paging encoder at 512, 1200, and 2400 baud ð Optional two-tone and group-tone paging ð 1000 pager database ð Group paging ð 8 external alarm inputs for automatic generation of pre-programmed pages. ð Pages may be initiated from DTMF equipped two-way radios. ð Built-in speaker and microphone, with provisions for external connections. ð May optionally be programmed and operated using an external keyboard The OSMAC BaseOSMAC Base operates in one of two basic modes. They are the Page Mode and the Program Mode. The Page Mode is used to send digital pages to a selected pager or group of pagers. It may also be used to communicate with a two-way radio. For the OSMAC BaseOSMAC Base to send pages to a pager, it must first be programmed with the pager's CAP code. This is done once, using the Program Mode. The Program Mode is used to set up the individual pager's information, group information, automatic paging information, and some system-level features. Although the operator may send pages using the built-in keypad or an external keyboard, pages may also be generated in a variety of other ways. Pages may be initiated through the two RS-232 serial ports on the rear of the unit. Another way is to use the built-in telephone interface. When connected to a telephone line, pages may be entered using a touch-tone phone by dialing into the unit. The OSMAC BaseOSMAC Base may also be configured to automatically generate a page, based upon an electrical input to special input pins on the rear of the unit. The OSMAC BaseOSMAC Base is one of the most versatile paging devices on the market today! The OSMAC BaseOSMAC Base has an internal database, which stores the CAP code for every pager in your system. The CAP code is the special 7 digit code that identifies an individual pager or paging receiver device. To make paging simpler, you need only configure the CAP codes once by assigning it an easy-to-remember number. For instance, you may have 3 pagers with the following CAP codes: 1924589, 0029111, 0935199. You can program them into the database as pager numbers 1, 2, and 3 as follows: Pager CAP Code Pager Number 1924589 1 0029111 2 0935199 3 Now, when it comes time to page pager 2, you will only have to enter the digit 2, rather that the whole CAP code. Other parameters that must be entered into the database for each pager are the pager type (tone, numeric, alpha-numeric), baud rate (512, 1200, 2400) active or inactive status, and which groups it belongs to (if any).

OSMAC BaseOSMAC Base User Manual Page 7 2.4 Display There is a two-line, twenty-character LCD display on the OSMAC BaseOSMAC Base. The three LEDs on the top right side of the unit indicate the state of the transmitter, whether the channel is busy, and the programming mode. 2.5 Sending a page The OSMAC BaseOSMAC Base is ready to send a page when the LCD display shows: This means the OSMAC BaseOSMAC Base is waiting for you to enter the pager number to which you which to send a page. Using the keypad or an external keyboard, enter the number (not the CAP code) of the pager you wish to page. Once you enter the pager number, press the F1 key. There are three standard types of pagers supported by the OSMAC BaseOSMAC Base. They are: tone-only, numeric and alpha-numeric. An option is available which supports two-tone pagers as well. Depending upon what type of pager you are sending the page to, one of the following sequences will take place: 1. POCSAG tone-only pagers If the pager is a tone-only type, it does not have a display. A page sent to it will cause it to beep. When a page is sent to it, the display will show TONE PAGER TONE PAGER while it is sending the page over-the-air to the pager. This will take about one second, after which it will display PAGE ACCEPTED PAGE ACCEPTED for a couple seconds, and then return back to the PAGER NO= PAGER NO= prompt. 2. Numeric and alpha-numeric pagers If the pager is designated as a Numeric pager or an Alphanumeric pager in the OSMAC BaseOSMAC Base database, then the LCD display will show NUMERIC PAGER NUMERIC PAGER or ALPHA PAGER ALPHA PAGER for one second, and then the LCD display will show ENTER MESSAGEENTER MESSAGE. The user enters the message using the keypad into line 2 of the display. If the message is longer than the length of the display, the display will automatically scroll down to the next line as the message is entered. Pressing the DEL key deletes the previous character entered. Once the data is entered, press the F1 key to send the page. The display will show PAGE ACCEPTEDPAGE ACCEPTED for a couple seconds and then the display will return back to the PAGER NO= PAGER NO= prompt. Note that: • Only messages with numbers may be sent when using the built-in keypad. • Alphanumeric messages may be sent to alphanumeric pagers when using an external keyboard or the computer interface. • The POCSAG characters "[", "]", "-", "space" and "U" may be sent to numeric pagers when using the external keyboard, mobile radio or the computer interface. 3. Two-tone pagers Two tone pagers accept a sequence of two tones. The CAPCODE is a number between 0 and 999. A large number of standard tone plans are supported by the OSMAC BaseOSMAC Base. . Pagers with non-standard tone frequencies may be programmed via the database upload command. After the paging tones are sent, an alert sound or a voice message from the telephone interface or console may optionally be sent to the pager. Alternatively, the phone patch may be initiated. Typically it takes a second or more to send a page to a pager. If the page is intended for a group of pagers, it may take longer. A group consisting of 10 pagers may take 5-10 seconds to transmit, and a group of 100 pagers may take 50-100 seconds to transmit. PAGER NO =PAGER NO =

OSMAC BaseOSMAC Base User Manual Page 8 2.6 Group Page The OSMAC BaseOSMAC Base can send a page to a group of pager numbers through the entry of a single group number. The pager numbers that are members of the group must have been previously assigned using the Assign Group configuration menu. When sending a group page, the OSMAC BaseOSMAC Base sequentially sends the page to each pager in the group. The procedure for sending a group page is the same as for the individual page described in the above procedure. Group pages generally take longer to send out, so you may find the OSMAC BaseOSMAC Base will take a bit longer to return to the PAGER NO=PAGER NO= prompt when a group page is sent. 2.7 Tone Paging to Alphanumeric or Numeric Pagers Some pagers can receive tone or numeric pages. If you wish to send a tone page (make it beep) to a POCSAG pager that is set-up for numeric or alpha paging, you can press the F4 (Tone) key when entering the page instead of the F1 (Enter) key. Pressing the F4 key after entering the pager number will force the OSMAC BaseOSMAC Base to send a tone page to the pager. 2.8 2-way voice communications The OSMAC BaseOSMAC Base can communicate with portable and mobile two-way radios. The OSMAC BaseOSMAC Base has a privacy feature called Continuous Tone Coded Squelch System (CTCSS). CTCSS blocks the reception of signals or noise that are not encoded with certain preset low frequency tones. You will only hear signals at the OSMAC BaseOSMAC Base that have the correct CTCSS tone encoded on them. This means that the radio channel may be in use by someone else, and you will not hear anything come out the speaker because the CTCSS decoder has muted it. To disable the CTCSS decoder momentarily in order to monitor all of the communications on the channel, press the F2 key on the built-in keypad. To talk on the radio channel, press and hold down the F3 key on the built-in keypad. If the channel is not in use, the OSMAC BaseOSMAC Base will turn the transmitter on and display TALKTALK on the LCD. Your voice will be transmitted out over the air. The microphone is located on the front of the unit, so speak clearly towards it in a normal voice. 2.9 Alarm Pages The OSMAC BaseOSMAC Base has 8 alarm inputs located at the rear of the unit. The unit may be configured to send a page when an alarm input changes states. Different messages may be sent for high or low going changes of state. For convenience sending pre-programmed messages, alarm pages may also be initiated from the external keyboard. Low change alarm messages may be generated by pressing CTRL and a number key "n" simultaneously, where "n" is the desired alarm number. High change alarm messages may be generated by pressing CTRL, SHIFT and the number key simultaneously.

OSMAC BaseOSMAC Base User Manual Page 9 3 Two-way Radio and Telephone Operation The OSMAC BaseOSMAC Base has a built-in radio transceiver enabling it to communicate with other two-way radios and to receive over-the-air commands to generate pages, connect to the telephone system, dial phone numbers and answer incoming telephone calls. The telephone interface may be utilized for generating pages or initiating phone patches with two-way-radios. To remotely control the OSMAC BaseOSMAC Base with a two-way radio or from a telephone, the two-way radio or telephone must be equipped with a DTMF encoder. All commands sent to the OSMAC BaseOSMAC Base are entered via the DTMF keypad, and in most cases, the commands are similar to the ones used locally on the OSMAC BaseOSMAC Base's built-in keypad. During two-way radio operations, the OSMAC BaseOSMAC Base will not transmit pages. Any pages entered by the front panel, external keyboard or computer ports will be queued and send later, when the radio is idle. 3.1 Sending Pages from the Two-Way Radio This section describes how to send a page with the OSMAC BaseOSMAC Base using a DTMF keypad-equipped two-way radio. The OSMAC BaseOSMAC Base and the two-way radio must have previously been configured to communicate on the same channel, and utilize the same CTCSS tones. To send a page to a pager from the two-way radio, you must: 1. Send *9 to alert the OSMAC BaseOSMAC Base that you intend to send a page. 2. If desired, optionally listen to the receiver for the "Enter Pager Number" prompt, which is a sequence of three beeps. A series of alternating high and low beeps indicates an error in the command sequence or a timeout occurred. If voice prompts have been enabled, then a voice message will be heard instead of the beeps. 3. Enter the digits of the pager number you wish to page. If the pager's number is less than three digits in length, then press the *key to terminate the pager's number. Note that the *key is not used to terminate three digit pager numbers. 4. If desired, optionally listen to the receiver for a low / high beep sequence, which signifies that the pager number was accepted. A series of alternating high and low beeps indicates an error in the pager number or a timeout occurred. If voice prompts have been enabled, then a voice message will be heard instead of the beeps. 5. Enter the numeric digits you wish to send to the pager. Do not enter any digits if you only wish to "beep" the pager. Note that the following DTMF keys have special meanings: DTMF Key Pager Character Comments * - Hyphen character # {none} Send the page A Space character B ] Right bracket C [ Left bracket D U Urgency indicator 6. Press the # key to send the page. To send a new message to the same pager again, you may: 1. Type *0 to alert the OSMAC BaseOSMAC Base that you intend to send a page to the same pager number as before. 2. Continue from step 4 of the instructions above to input the new message to be sent.

OSMAC BaseOSMAC Base User Manual Page 10 3.2 Placing Telephone Calls from the Two-Way Radio Two-way radios can place "autopatch" telephone calls through the OSMAC BaseOSMAC Base to a telephone line connected to the rear of the OSMAC BaseOSMAC Base. The OSMAC BaseOSMAC Base operates in a simplex mode. In other words, it can only receive or transmit at any given time, and not both simultaneously. If it is transmitting, it cannot receive, and when it is receiving, it cannot transmit. Because of this, there are a number of things to keep in mind when making or receiving a telephone call through the OSMAC BaseOSMAC Base. One is that the two-way radio user will hear an occasional ticking sound. This is the OSMAC OSMAC BaseBase periodically checking for transmissions from the two-way radio. The other is that users must learn to wait about a second before talking whenever the OSMAC BaseOSMAC Base switches between transmit and receive modes. The OSMAC BaseOSMAC Base uses a Voice Operated Switch (VOX) circuit on the telephone line. VOX circuit switches the OSMAC BaseOSMAC Base from transmit mode to receive mode when it detects that the audio coming in from the telephone line has stopped. To place a telephone call: 1. Press the *7keys on the two-way radio's DTMF keypad. This tells the OSMAC BaseOSMAC Base that you wish to place a telephone call. 2. Optionally listen for the confirmation beeps to come back from the OSMAC BaseOSMAC Base. If autopatch operation has been disabled from the Configuration Menu, then alternating high and low beeps will signal an error. If voice prompts have been enabled, then a dial tone will be heard instead of the beeps. 3. Begin dialing the telephone number you wish to call after the dial tone ends. At the end of the telephone number, you may enter a *to dial the phone number. Alternatively, the phone number will be dialed if no keys are pressed after a few seconds. The DTMF tones being sent to the phone line will be heard to confirm dialing. 4. Once the called party answers, the phone VOX circuit takes over. When the called party speaks, the OSMAC OSMAC BaseBase transmits his or her voice. 5. A periodic ticking sound will be heard by the mobile user as the OSMAC BaseOSMAC Base briefly switches to receive mode to determine whether the mobile user wishes to interrupt the conversation and has begun transmitting. 6. If neither party is talking, a single beep will be heard periodically to remind the mobile user that the phone patch is still in operation. 7. A timeout timer exists in order to shut down the phone patch automatically in the event that the mobile user goes out of range or has a battery outage. Warning beeps or a voice message will be sent 30 seconds before the timeout timer expires and the phone call is terminated. The mobile or phone user may press * in order to reset the timeout timer and continue the phone call. 8. End the conversation from the two-way radio or the phone by pressing the # key. A high, then low beep sequence or a voice message should be heard to confirm the disconnection. 3.3 Autodial Calls The OSMAC BaseOSMAC Base has 10 "auto-dial" memories containing telephone numbers that can be automatically dialed. See the Programming section for information on how to program these numbers. In order to make an Autodial call from a two-way radio: 1. Press the *6 keys on the two-way radio's DTMF keypad, followed by the number of Autodial memory you wish to place the call to. Memory number 0 will be used if no number is sent after the *6 command. 2. Operation continues from step 4 as described above.

OSMAC BaseOSMAC Base User Manual Page 11 3.4 Receiving Telephone Calls at the Two-Way radio The OSMAC BaseOSMAC Base can also be used to route telephone calls from the telephone line to two-way-radios. To initiate a phone call from the telephone interface: 1. Dial the phone number of the telephone line connected to the OSMAC BaseOSMAC Base. 2. The will display "Phone Ringing" when the ring signal is detected and wait for the number of rings programmed in the Configuration Menu. 3. The OSMAC BaseOSMAC Base will answer the phone in a manner determined by the settings of the "Remote Paging" and "Call Forwarding" modes as set in the Configuration Menu. The display will read "Phone in Use." Remote Paging Call Forwarding OSMAC BaseOSMAC Base Operation When Called Enabled Enabled • Phone answered with a "Enter Pager Number" prompt. • User may press * 5 to request a phone patch and send "ringing" tones to the two-way-radio users. • User may enter the number of a pager to be paged and a numeric message. Enabled Disabled • Phone answered with a "Enter Pager Number" prompt. • "Error" tones are generated if the user presses * 5 . • User may enter the number of a pager to be paged and a numeric message. Disabled Enabled • Phone answered with "ringing" tones which are also sent to the two-way-radio users to request a phone patch. Disabled Disabled • The phone line is not answered 4. The telephone user must enter *5 to request a "reverse autopatch" phone call if "Remote Paging" is enabled. 5. If "Call Forwarding" is enabled and the telephone line rings, the OSMAC BaseOSMAC Base will transmit a simulated ring signal over the air. To answer the call, a mobile user must press the * key to take the telephone line off-hook. To hangup the call, either the phone or mobile user must press the # key. 6. Once the called party answers, the phone VOX circuit takes over. When the phone user speaks, the OSMAC OSMAC BaseBase transmits his or her voice. 7. A periodic ticking sound will be heard by the mobile user as the OSMAC BaseOSMAC Base briefly switches to receive mode to determine whether the mobile user wishes to interrupt the conversation and has begun transmitting. 8. If neither party is talking, a single beep will be heard periodically to remind the mobile user that the phone patch is still in operation. 9. A timeout timer exists in order to shut down the phone patch automatically in the event that the mobile user goes out of range or has a battery outage. The length of the timer is set in the Configuration Menu. Warning beeps or a voice message will be sent a few seconds before the timeout timer expires and the phone call is terminated. The mobile user or phone user must press * to reset the timeout timer and continue the phone call. 10. End the conversation from the two-way radio or phone by pressing the # key. A high, then low beep sequence or a voice message should be heard to confirm the disconnect.

OSMAC BaseOSMAC Base User Manual Page 12 3.5 Sending Pages using the Telephone Interface This section describes how to send a page with the OSMAC BaseOSMAC Base using a DTMF keypad-equipped telephone. Note that the phone will not be answered until any "radio paging" command sequence in progress is completed. To send a page to a pager from the telephone interface, you must: 1. Dial the phone number of the telephone line connected to the OSMAC BaseOSMAC Base. 2. If the "Remote Paging" mode has been enabled from the Configuration Menu, the OSMAC BaseOSMAC Base will answer the phone and send an "Enter Pager Number" prompt, which is a sequence of three beeps. If voice prompts have been enabled, then a voice message will be heard instead of the beeps. 3. Enter the digits of the pager number you wish to page. If the pager's number is less than three digits in length, then press the *key to terminate the pager's number. Note that the *key is not used to terminate three digit pager numbers. 4. If desired, optionally pause sending beeps and listen for a low / high tone sequence, which signifies that the pager number was accepted. A series of alternating high and low beeps indicates an error in the pager number or a timeout occurred. If voice prompts have been enabled, then a voice message will be heard instead of the beeps. 5. Enter the numeric digits you wish to send to the pager. Do not enter any digits if you only wish to "beep" the pager. 6. Press the # key to send the page. You will hear a series of beeps increasing in pitch or a voice message to indicate that the page was sent. 7. If a two tone pager with the "TONE+VOICE" function enabled has been paged, a voice prompt will be given instructing the caller to speak a voice message. If a two tone pager with the "TONE+PATCH" function enabled has been paged, the phone patch will be connected automatically. 8. If the caller hesitates sending DTMF tones for a numb er of seconds, a series of alternating high and low beeps or a voice message will be sent, indicating that a timeout occurred. 9. The OSMAC BaseOSMAC Base will then hang-up the phone line.

This may be used if the OSMAC BaseOSMAC Base is in a location where sounds from the speaker are not desirable. 4.1.3 Busy Channel Lockout If this mode is enabled, then the OSMAC BaseOSMAC Base will not transmit if the channel is busy. This may be desirable in order to avoid interfering with other users on the channel. This mode should be disabled if there is so much activity on the channel that the pages are not sent out in a timely manner. 4.1.4 Remote Paging If this mode is enabled, then remote users are permitted to call the OSMAC BaseOSMAC Base via a telephone line and to generate pages to be transmitted. 4.1.5 Call Forwarding If this mode is enabled, then remote users are permitted to call the OSMAC BaseOSMAC Base via a telephone line and to request a phone autopatch with two-way-radio users. 4.1.6 Autopatch Timer The autopatch timer establishes the length of time the OSMAC BaseOSMAC Base waits before hanging up the autopatch automatically. This is needed in case the two-way-radio user's batteries fail or he goes out of range Enter the number of minutes the autopatch may be operated before the disconnect warning tones are sent. The DEL key may be used to delete digits. Press the "-" key to exit the menu. Note that autopatch operation may be disabled by setting the Autopatch Timer value to 0.

OSMAC BaseOSMAC Base User Manual Page 16 4.1.7 Voice Prompts This mode selects whether beeps or voice prompts are used to confirm radio and phone operations with the OSMAC BaseOSMAC Base.. The language of the voice prompts is determined by which firmware file has been loaded. If you are interested in a language other than English, contact your distributor for availability. 4.1.8 Warmup Signal If this mode is enabled, then a special "warmup" signal is transmitted for a brief period of time at the beginning of each page. This is required for more reliable operation by some pagers. 4.1.9 Rings to Answer The phone will be answered after the number of rings specified. Enter 0 to answer the phone immediately after detection of a phone ring. 4.1.10 Transceiver Setup The OSMAC BaseOSMAC Base either contains a two-way transceiver or works with an external transceiver. In either case, the factory has programmed the correct Transmitter Type, Carrier Detect inversion, Transmit Data inversion, and the TX Bandwidth. The user should not change these settings or improper operation will result. 4.1.11 TX/RX Switch Time This parameter is used by the autopatch to determine the sampling time to listen for the mobile radio user when transmitting the phone user's voice. If it is set too small, the mobile radio user will not be able to interrupt the transmitter when in the autopatch mode. If it is set too large, then the transmitter's dropout time will be excessive. 4.1.12 Transmit and Receive Frequencies Enter the desired transmit or receive operating frequency using the number keys. The decimal point will automatically be entered. Use the DEL key to delete any correct entries. Press the F1 or "-" key to accept the new frequency. 4.1.13 Transmit and Receive Signaling Carrier Squelch operation may be desirable if there are no other users on the channel and there is no interference. In this mode, the two-way-radio users will be able to hear the paging signals transmitted by the OSMAC BaseOSMAC Base. To enable this mode, press 1 to select (CARRIER ONLY). Press the "-" key to exit the menu. If there are other users sharing the channel, if there is excessive interference, or if the two-way-radio users do not want to hear the paging signals, then CTCSS operation should be used. In this mode, a low frequency tone is transmitted along with the desired audio. The receiver will only be enabled if this tone is present at the correct frequency. To enable this mode, press 2 to select CTCSS, then use the arrow keys to select the desired tone frequency. Press the "-" or F1 key to accept the frequency and exit the entry mode. 4.1.14 TX Data Delay This parameter controls the delay between the time the transmitter is turned on and the start of the transmit preamble for POCSAG pages. The delay is given in milliseconds. 4.1.15 Shift CPU Clock In rare cases, the desired receive frequency may coincide with computer noise generated by the internal CPU. This option enables the user to change the CPU's timing, which may shift the CPU's computer noise away from the desired receive frequency.

OSMAC BaseOSMAC Base User Manual Page 17 4.1.16 CW Identification Call Sign In many cases, the rules and regulations under which the OSMAC BaseOSMAC Base is licensed by the government require that the station's Call Sign be transmitted at regular intervals for identification purposes using Morse Code. The OSMAC BaseOSMAC Base sends the Call Sign (with CTCSS turned off so the mobile radio users won't hear it) every 10 minutes if the Call Sign has been programmed. This feature is disabled when the unit comes from the factory. To enable this feature, press 5 from the main configuration menu. At the prompt, enter your station's Call Sign from your license as follows: • Numbers are entered directly from the keypad. • Letters and other special symbols are entered from the keypad by pressing the arrow keys. Alternatively, an external keyboard may be used to enter alphanumeric characters directly as typed. • Press the F2 key to accept the displayed letter when using the unit's keypad or to enter a "space" character which is displayed as a "_" and results in a pause in the Morse Code. • Press the DEL key to delete errors or to disable CW Identification by totally clearing the display. • Press the F1 or "-" key to accept the Call Sign and exit the menu. • Up to 19 characters may be contained in the CW Identification string.

OSMAC BaseOSMAC Base User Manual Page 18 5 Program Mode The Program Mode is used to program CAP codes, add pagers, delete pagers, assign pagers to groups, configure the alarm pages, and set up various features of the OSMAC BaseOSMAC Base. To enter the programming mode, press the dash "-" key on the keypad or the ESC key on the external keyboard. The OSMAC BaseOSMAC Base will prompt you to enter the password. After entering the Program Mode password (7531) and pressing F1, you can select one of the following menu items: 1 = Assign Pager1 = Assign Pager Assigns pager CAP codes 2 = Assign Group2 = Assign Group Assigns pagers to groups 3 = Test Page3 = Test Page Sends periodic test pages 4 = Alarm Pages4 = Alarm Pages Configures alarm triggered pages 5 = autodial memory5 = autodial memory Configures Autodial memories -- = RETURN TO PAGE = RETURN TO PAGE Return back to the page mode When you enter the Program Mode you will see the first selections. Use the UP/DOWN arrows to scroll through the available options. To exit the Program Mode, press the - (Program) key or the ESC key. Any changes you make will automatically be saved. Note: When the OSMAC BaseOSMAC Base is in the Program Mode, it will revert back to the Page Mode if it is idle (no keyboard inputs) for two minutes, except that test pages may be sent for an unlimited period of time. 5.1 Assign Pager All pagers have an ID code, commonly referred to as a CAP code. It is a long number, difficult to remember, and may change if a pager is replaced or in for repair. To make paging a pager easy, the OSMAC BaseOSMAC Base uses a database stored in its memory to remember every pager's CAP code. Within the OSMAC BaseOSMAC Base, every pager is assigned a Pager Number. Because pagers only recognize CAP codes, the OSMAC BaseOSMAC Base must translate the pager number into the proper CAP code. The 1 1 -- Assign Pager Assign Pager menu is used for this function. 1. Begin by entering the Programming Mode as described above, and pressing the number 1 key. The OSMAC OSMAC BaseBase will respond with: PAGER No = PAGER No = F1:OK F2:BACK F1:OK F2:BACK -- :: EXITEXIT Note that the F1 key is used to select an entry, the F2 key goes back to the previous menu item and the - key exits this mode. 2. Enter the number for the pager you wish to add to the database. For example, to add a pager number "15" to the database press 1 then 5 then F1. 3. Next, you will be prompted to activate or deactivate the pager. Press F1 to activate it, or press an arrow key to switch between Y and N on the display to deactivate it. Press F1 when the correct response has been chosen. 4. Next, tell the OSMAC BaseOSMAC Base what type of pager is being assigned. For convenience, the will display the type of pager previously selected. Press the arrow keys to cycle through the list of possible pager types. The possible types are: POCSAG 512, POCSAG 1200 and POCSAG 2400. An option is available which also supports TWO TONE pager types. Note that the OSMAC system must have all pagers set to 512 baud POCSAG. Once the correct paging format type is in the display, press the F1 key on the keypad or ENTER on the external keyboard. 5. After programming the type, you must program in the function type of the pager being used. The function type for POCSAG pagers is one of the following:

OSMAC BaseOSMAC Base User Manual Page 19 • TONE (pager just beeps) • NUMERIC (pager beeps and displays numbers) • ALPHA (pager beeps and displays numbers and letters.) The function type for TWO TONE pagers or GROUP TONE pagers is one of the following: • TONE ONLY (send page tones only) • TONE+ALERT (send an alert sound after sending the page tones) • TONE+VOICE (permit phone caller to speak to the pager after sending page tones.) • TONE+PATCH (initiate a phone patch after sending the page tones) 6. Press the arrow keys to cycle through the list of functions. Press the F1 key when the correct function is displayed. 7. If TONE+ALERT or TONE+VOICE was selected, then you will be asked to specify the duration of the alert or the voice connection after the paging tones have been sent. You may give a value between 0 and 31 seconds. Entering 0 will cause an alert tone of 1/2 second or use the default voice duration of 15 seconds. 8. If a TWO TONE pager has been selected, you will be asked to select the tone plan for the pager. Use the arrow keys to scroll through the supported plan types. If the tone plan for your pager isn't listed, then the pager's tone frequencies must be entered using the database upload command. 9. Once a pager number is entered, the OSMAC BaseOSMAC Base will respond with a prompt asking for the CAP code for this pager. If the pager number was already in the database, it will display the CAP code already programmed. If it was not in the database, the CAP code will default to the pager number. To edit the CAP code, use the DEL key to backspace over it. Press F1 to enter the new CAP code. 10. If a TWO TONE pager has been selected, you may be asked to specify whether the "diagonal frequency" is the first or second tone. Alternatively, you may select a "group tone" for the pager. This will send a single tone to the pager with a pre-determined duration. 11. The OSMAC BaseOSMAC Base restart back at the PAGER NO = PAGER NO = prompt. It will automatically increment to the next pager number. Press the - to exit the Program Mode when all of the pagers have been entered into the database. Your entries into the pager database will then be saved in the internal FLASH memory. 5.2 Assigning a Group The Group-Page feature is used to send the same page to a number of different pagers. Groups have numbers just like pagers, and once you define a group and its members, you send pages to the group just as if it were a single pager. When you assign a number to a group, it is important that the number is not the same as any individual pager. There is a limit to the number of pagers that may be assigned to any one group. This is listed in the Specifications section of the OSMAC BaseOSMAC Base User Manual. 1. To do the group assignments, select 2-Assign GROUP from the program mode menu. The display will then show: GROUP NUMBER = GROUP NUMBER = SELECT GROUPSELECT GROUP 2. Enter the number of the group you wish to work on and then press the F1 key. Valid group numbers are 1 through 16. The display will then show:

OSMAC BaseOSMAC Base User Manual Page 20 GROUP X PAGER NNGROUP X PAGER NN assign pager numberassign pager number Where X is the group number you wish to work on and NN is the pager number assigned to this group. Important Note: when you wish to page this group, you will enter the pager number NN for it, not the group number. 3. Use the DEL key to backspace over NN if you wish to change the pager number this group is referred to by. If the pager number NN is already assigned to an active pager, the will not allow you to assign that number to the group and the pager number will be erased. If you wish to use NN for a group number instead of an individual pager, you must first de-activate the pager. Section 3.1 describes how to deactivate a pager. Once the pager number for this group is set, press the F1 button. The following prompt will appear. GROUP X = numericGROUP X = numeric SELECT GROUP FUNCSELECT GROUP FUNC 4. Using the arrow keys, select the function (numeric, alpha or tone) for this pager group. Members of the group may be of any type, but this selection will determine the prompt to the user when a page to this group is initiated. Press F1 when your selection is made. The display will change to : GROUP X MEMBER NNGROUP X MEMBER NN ENTER MEMBER NUMBERENTER MEMBER NUMBER 5. X will be the group number you are currently working on, and NN will be a number corresponding to the member number you wish to edit. The first group member you enter will be member 1. The second one you enter will be member 2 and so on. The display always first shows the next member number you can enter a new member as. Use the UP/DOWN arrows if you wish to scroll through the members, or press the DEL key to edit the member number and manually enter the member number to edit. Press F1 key when you are ready to edit/add the selected group member. The display will then show: MEMBER NN = MEMBER NN = ENTER PAGER NUMBERENTER PAGER NUMBER 6. Enter the number of the pager you wish to add to the group. For example if you wish to add pager number 123 to the group, then enter 1 2 3 and then press the F1 key. Use the DEL key to backspace over any entry if you wish to edit it. Note that: • To see the pagers in the database are members of this group, you can use the UP/DOWN arrow key to scroll through the members of the group. • To delete a member, at the MEMBER NN = MEMBER NN = prompt, use the DEL key to erase its number from the screen, and press the F1 key. 7. To finish entering pagers to this group, press the - key.

OSMAC BaseOSMAC Base User Manual Page 21 5.3 Sending Test Pages The test page mode may be used to check the range of the system. With this mode, the OSMAC BaseOSMAC Base will automatically generate a page to pager number "0" every ten seconds. 1. Before using this feature, pager number "0" must be programmed as described above. 2. To enable this feature, enter the program mode and press 3. The display will show: PAGING pAGEr 0 dash (-) to exit 3. Press the - key to return to the programming mode menu. 5.4 Alarm Pages The OSMAC BaseOSMAC Base has 8 alarm inputs. These digital inputs are used to generate pre-programmed pages, each with its own pre-programmed message to any pager, or group of pagers. These may be used for alarms, but they may also be used to simply generate pre-programmed pages. The inputs may be connected to normally-open switches or contacts. When any input is pulled low to ground, it will generate a pre-programmed page. When any input is pulled high or allowed to "float high", it will generate a different pre-programmed page. Alternatively, alarm pages may be initiated from an external keyboard. Hold down the CTRL key and then press a number key which corresponds to the alarm input number to send the "Alarm Low" message. Hold down the SHIFT key also to send the "Alarm High" message. Note that the alarm inputs are not protected from lighting, so the wires must not be run out of doors. See Section 10.2 for details regarding the wiring of the alarm input connector. To set up the alarm pages, the user must perform the following steps: 1. Put the unit into the program mode. 2. Press 4 to enter the Alarm sub-menu. 3. When the ALARM NUMBER = prompt is shown, enter the number of the alarm you wish to configure. Press the F1 key. 4. The OSMAC BaseOSMAC Base will display AlaRM x PAGER on the top line, and the pager number that will be paged when the alarm is triggered. Erasing the pager number disables the alarm. Enter the number of the pager you wish to have paged when the selected alarm input is triggered. Press F1 when done. 5. OSMAC BaseOSMAC Base will display ALARM low MSG: on the top line of the LCD. On the second line, you may enter or edit the message to be sent when the alarm input goes low. Press F1 when the message has been entered. 6. OSMAC BaseOSMAC Base will display ALARM hi MSG: on the top line of the LCD. On the second line, you may enter or edit the message to be sent when the alarm input goes high. Press F1 when the message has been entered. When entering the alarm messages, the unit's keys operate as follows: • Numeric keys are used to enter numbers • F4 or UP keys select the next letter of the alphabet • F3 or DOWN keys select the previous letter of the alphabet • - key enters a "dash" character • F2 key enters a space character or moves to the next character position to the right • DEL key deletes a character and moves to the next character position to the left • F1 key accepts the entry and exits back to the previous menu. • Alphanumeric characters may alternatively be entered directly from an external keyboard 7. Press the F1 key to return to the programming mode menu.

OSMAC BaseOSMAC Base User Manual Page 24 7 Serial Port Protocols The OSMAC BaseOSMAC Base paging transmitter supports three different serial port communication protocols. Each protocol has its own uses, and the correct one for one application may not be the correct one for another. The OSMAC OSMAC BaseBase must be configured to support the desired protocol, and only one protocol may be used at a time. The three protocols supported are: TAP (also called IXO) The Telocator Access Protocol is an industry standard protocol for communications between paging entry devices and a paging terminal. Individual pagers can be sent individual messages. COMP1 This protocol is a simple way to send data to one pager. It is designed to allow a person with a simple computer terminal to type a message into the OSMAC BaseOSMAC Base. The OSMAC BaseOSMAC Base must be pre-configured with the CAPCODE of the pager to send the data to, and all data sent into the serial port of the OSMAC BaseOSMAC Base will be sent to that one pager. COMP2 COMP2 is similar to COMP1, except each page requires two lines of text to be entered. The first line is the pager number to send the page to, and the second line is the alpha or numeric message to send to that pager. 7.1 TAP The Telocator Alphanumeric Protocol, or TAP protocol as it is called, is used to send pages to communicate paging information to a transmitter. It is a sequence of characters sent over a serial interface to a transmitter. The transmitter must parse the commands, and take the appropriate actions. The following sections describe how the TAP protocol works. It assumes that the device communicating to the OSMAC BaseOSMAC Base Station is directly connected to it via a serial cable. If other means are used (i.e. modem) then the modem connection must first be established. For the purposes of this manual, the OSMAC BaseOSMAC Base is assumed to be the transmitter, and the device connected to its serial port is the "Entry Device". Typical entry devices are computers, paging terminals, and alarm monitors. Characters listed in brackets <xx> are ASCII codes, and the values for them are listed at the end of this document. Initiating a Page Entry Device OSMAC Base Action Comment <CR> The Entry Device should send a <CR> at two second intervals until the OSMAC BaseOSMAC Base responds with the characters ID=. The <CR> is an ASCII code 13h. ID=<CR><LF> The OSMAC BaseOSMAC Base will respond within one second of the <CR>, and it does not end the ID= prompt with a <CR> or a <LF>.

OSMAC BaseOSMAC Base User Manual Page 25 After initiating a page, and receiving the ID= prompt, the Entry Device can respond in one of two different ways. One way puts the OSMAC BaseOSMAC Base into an Automatic Mode, and the other ways puts it into a Manual Mode. Automatic Entry of a Page Entry Device OSMAC Base Action Comment <ESC>PG1<CR> The Entry Device tells the OSMAC BaseOSMAC Base transmitter that it wants to automatically send a POCSAG page by ending this sequence. <CR><ACK><CR> or <CR><NAK><CR> or <ESC><EOT><CR> The OSMAC BaseOSMAC Base will respond within one second of the ACK sequence signifying that the Entry Device has successfully logged on to the OSMAC BaseOSMAC Base. If paging entries cannot be accepted, it will respond with the NAK sequence or the ETX sequence, which should force the Entry Device to disconnect. <ESC> [p <CR> This "go ahead" sequence tells the Entry Device that it is OK to go ahead and send over the information for the first page or pages. The p is always the lower case "p". <STX> PagerID<CR> Message<CR> <ETX> Checksum <CR> This Pager/Message Sequence Block tells the OSMAC BaseOSMAC Base the ID (the Pager Number in the OSMAC BaseOSMAC Base's database) of the pager this the Message is to be sent to. The checksum is computed as shown later in this document. The total number of characters sent from the Entry Device per sequence should not exceed 255. Repeat the above Pager/Message Sequence Block as many times as required, if more pages are to be sent. <EOT> <CR> When the Entry Device does not want to send any more pages, it sends this EOT sequence, to tell the OSMAC BaseOSMAC Base that it is finished with this automatic session. Pages Accepted <CR> or Invalid Page Entered<CR> or <Message><CR> One of these status messages will be returned at the end of the session. They are for information purposes only. <CR><RS><CR> This is only sent if there was an error in this session, probably due to an invalid pager ID or a message type mismatch. PAGING EXCHANGE DISCONNECT <CR> <ESC> <EOT> The End of Transaction message sent from the OSMAC BaseOSMAC Base to the entry device, telling it to disconnect.

OSMAC BaseOSMAC Base User Manual Page 26 Manual Entry of a Page Entry Device OSMAC Base Action Comment M<CR> The Entry Device tells the OSMAC BaseOSMAC Base transmitter that it wants to manually send a POCSAG page, by ending the M. ENTER PAGER NUMBER: The OSMAC BaseOSMAC Base will respond within one second of the M sequence signifying that the Entry Device has successfully logged on to the OSMAC OSMAC BaseBase, and it is ready to receive paging info. The OSMAC BaseOSMAC Base begins by responding with this prompt. PagerID<CR> The user responds with the ID of the pager he wishes to page. Enter Alpha Message: or Enter Numeric Message: The OSMAC BaseOSMAC Base responds with one of the following messages, depending upon the type of pager that the PagerID is assigned to. Message<CR> The user enters a message to send to the pager. Sending Message...<CR> The OSMAC BaseOSMAC Base displays this message as it sends the message to the pager. MessageSent<CR> or Can't Deliver to xxxxxxx<CR> or Too Slow. Goodby.<CR> or Two many errors. Goodby. <CR> One of these messages will then be sent from the OSMAC BaseOSMAC Base, depending upon the current situation with the page that was entered. The serial port has a 45 second activity time, and will force and end to the manual session if the user does not complete the page in that time. 7.2 TAP Protocol Issues 7.2.1 Timing The OSMAC BaseOSMAC Base will wait for a response to come back from the Entry Device. If a response is not received before the pre-programmed time-out period, the OSMAC BaseOSMAC Base will cancel the current transaction, sending the <ESC> <EOT> <CR> sequence. 7.2.2 Line Feeds The OSMAC BaseOSMAC Base will ignore all <LF> characters it receives. The Entry Device may send a <LF> with any <CR>. XOFF In the very unlikely event that the user enters more pages than the OSMAC BaseOSMAC Base can queue up, the OSMAC BaseOSMAC Base will send the <XOFF> character before sending a carriage return. It will send the <XON> character when buffer space is available for more pages. If the OSMAC BaseOSMAC Base does not receive data within 10 seconds after sending an <XON>, it will send another <XON>. 7.2.3 EOT Whenever the OSMAC BaseOSMAC Base terminates a session by sending the <EOT><CR> sequence, it will drop the DTR signal on the RS-232 signal for 250mS. This will normally cause any modem connected to it to disconnect.

OSMAC BaseOSMAC Base User Manual Page 27 7.3 Sending Multiple-Line Pages If you wish a message to continue on another line of a multi-line pager, you cannot send the <CR> return into the serial port. Use the TAB character instead of a <CR>. The OSMAC BaseOSMAC Base will translate it to a <CR> when it sends the page to the pager. 7.4 Computing the Checksum The checksum is a simple arithmetic sum of the 7-bit values of all characters preceding it. The checksum reported is the least significant 12 bits of this summation, converted to BCD ASCII. Checksum Example: STX 000 0010 1 011 0001 2 011 0010 3 011 0011 <0CR> 000 1101 A 100 0001 B 100 0010 C 100 0011 <CR> 000 1101 ETX 000 0011 Total 10111 1011 Convert to BCD 1 0111 1011 Answer in BCD ASCII 1 7 ; 7.5 COMP1 COMP1 allows a "dumb terminal" to be used to send a page, although any device that can output RS-232 data can be used. All data entering the serial port is sent to pager number 0. The reception of a <CR> initiates the page. Manual Entry of a Page Entry Device OSMAC Base Action Comment <Message><CR> The Entry Device (in this case it is often a user on a terminal) types in the message to send to a pre-set pager. Characters are echoed back.

OSMAC BaseOSMAC Base User Manual Page 28 7.6 COMP2 COMP2 allows a "dumb terminal" to be used to send a page, although any device that can output RS-232 data can be used. It has the added capability of selecting which pager to send the data to. All data entering the serial port is sent to a specified pager. The reception of a <CR> initiates the page. If the last <CR> is not sent within the pre-programmed timeout period, the OSMAC BaseOSMAC Base will abort this transaction, and begin waiting for a new <Page #> entry.

OSMAC BaseOSMAC Base User Manual Page 29 8 Database Transfer For convenience managing databases containing a large number of pagers, for backup purposes and to facilitate cloning databases from one unit to another, the OSMAC BaseOSMAC Base database may be uploaded and downloaded from a host computer which is connected to either serial port which is configured for the TAP protocol. 8.1 Database Format The OSMAC BaseOSMAC Base database may be uploaded or downloaded as ASCII characters which can readily be transferred, stored and/or edited as desired. The format of the database output is as follows: DB1 VERSION, {VERSION}, {LANGUAGE}, {OPTIONS}, SERIAL, {PORT}, {BITS}, {STOP}, {PARITY}, {FLOW}, {BAUD}, {TAP-TO}, {COMP-TO}, {MAN-TO}, {PROTO}, MODE, {SPKR}, {BUSY}, {REMOTE}, {CALL}, {AP-TIMER}, {VOICE}, {WARMUP}, {RINGS}, RADIO, {T-REF}, {T-FRQ}, {T-TONE}, {BW}, {R-REF}, {R-FRQ}, {R-TONE}, {CD}, {DATA}, {TYPE}, {TR}, {CPU}, {DLY}, {PWR}, AUTODIAL, {MEMORY NUM}, {PHONE NUM}, PAGER, {0-999}, {TYPE}, {CAPCODE}, {FORMAT}, {GROUP}, {ACTIVE}, {DUR-A}, {DUR-B}, {DUR-C}, GROUP, {NUMBER}, {PAGER NUM}, {MEMBERS}, {SPARE}, {MEMBER 1}, …{MEMBER N}, ID, {ID STRING}, DONE Where: DB1 Signifies that the database download follows VERSION Signifies that the version string follows {VERSION} Firmware version string {LANGUAGE} Language of the voice prompts {OPTIONS} Firmware options SERIAL Signifies that this line is data for a serial port {PORT} Port number for this line's data {BITS} Number of data bits (0= 7 bits, 1= 8 bits) {STOP} Number of stop bits (0= 1 bit, 1= 2 bits) {PARITY} Parity (0= No Parity, 1= Odd, 2= Even) {FLOW} Flow control (0= None, 1= Xon/Xoff, 2= RTS/CTS) {BAUD} Baud rate (0= 300, 1= 600, 2= 1200, 3= 2400, 4= 4800, 5= 9600, 6= 19200) {TAP-TO} Timeout for TAP protocol in seconds {COMP-TO} Timeout for COMP protocol in seconds {MAN-TO} Timeout for manual entry mode in seconds {PROTO} Port protocol (0 = TAP, 1 = COMP1, 2 = COMP2) MODE Signifies that this line is data for mode settings {SPKR} Speaker enable mode on/off {BUSY} Busy channel lockout on/off {REMOTE} Remote enable on/off {CALL} Call forwarding on/off {AP-TIMER} Autopatch timer in seconds {VOICE} Voice Prompts on/off {WARMUP} Warmup signal on/off {RINGS} Number of rings before the phone is answered

$OSMAC BaseOSMAC Base User Manual Page 30 RADIO Signifies that this line is data for the radio transceiver {T-REF} Transmit reference frequency in Hz {T-FRQ} Transmit frequency in Hz {T-TONE} Transmit CTCSS code (-1 = CTCSS off) {BW} Transmit Bandwidth (0= wide, 1= narrow) {R-REF} Receive reference frequency in Hz {R-FRQ} Receive frequency in Hz {R-TONE} Receive CTCSS code (-1 = CTCSS off) {CD} Carrier detect inversion on/off {DATA} Transmit data inversion on/off {TYPE} Transceiver type code {0= NO_TX, 1= VHF 204, 2= UHF, 3= VHF 3464} {TR} Transmit/Receive switching delay in mS, used for autopatch sampling {CPU} Number of CPU wait states, used to shift CPU noise from receive channels {DLY} Delay from Transmitter ON to start of POCSAG preamble in mS {PWR} Transmitter Power Control word (Read only, used by 3412-X radios) AUTODIAL Signifies that this line is data for an autodial memory {MEMORY NUM} Memory number {PHONE NUM} Phone number ID Signifies that this line contains the CW ID for the unit {ID STRING} The ID String of the unit PAGER Signifies that this line is the data for a pager {0-999} Pager number for the data on this line {TYPE} Pager type: ALPHA, NUMERIC, TONE, ALERT, VOICE or PATCH {CAPCODE} Pager CAPCODE. If the pager is a group it will be the group number minus 1. For two-tone pagers, if DUR-A is not zero, CAPCODE contains frequencies of the two tones with the first tone's frequency in units of 1/10 Hz in bits 0 to 15 and the second tone's frequency in units of 1/10 Hz in bits 16 to 31. {FORMAT} Paging format: POC512, POC1200, POC2400, TWO-TONE or ONE-TONE {GROUP} Is either Y if it is a group pager, or N if it is not a group pager {ACTIVE} Is either Y is the pager is enabled, or N if it is de-activated {DUR-A} Duration of first tone in units of 50 mS for two-tone pagers with random frequencies, 0 otherwise. {DUR-B} Duration of second tone in units of 50 mS for two-tone pagers with random frequencies, 0 otherwise. {DUR-C} Duration of the two-tone pager's alert tone or the voice connection in seconds. GROUP Signifies that this line is the data for a group of pagers {NUMBER} Group number (1-16) {PAGER NUM} Pager number that references this group {MEMBERS} Number of pagers assigned to this group {SPARE} A blank entry for future use {MEMBER 1} The pager number for the first memb er. All other members follow this one, separated by commas. {MEMBER N} This is the pager number for the final member of the group DONE This entry signifies the end of the database. 8.2 Retrieving the Database The OSMAC BaseOSMAC Base will send the contents of its database out the serial port when it is given the command <ESC>SDB<CR>. The database is sent out at the currently configured baud rate in an ASCII format, with commas between the parameters and a <CR> at the end of each line.$
