2 3IntroductionThe me-d200/d350 range is a 1 to 5 Watt radio data modem, which can be used for data up to 9600 baud rate (using GMSK module) in stand alone conditions. The me-d200/d350 is housed in a rugged cast-aluminium box sealed to IEC 529 (IP54) making it suitable for a wide range of mobile and fi xed applications.All me-d200 modem units meet the essential requirements of the relevant European directives and all me-d350 modems meet relevant US FCC and Canadian regulations. In order to maintain this compliance the installation and safety information must be adhered to at all times.The me-d200/d350 modem must only be installed where unintentional contact cannot be made. The surface of the device may be hot to touch under certain transmit conditions. A warning label is permanently displayed as part of the equipment rating label affi xed to the lid. The me-d200/d350 is not designed for permanent transmis-sion. If prolonged transmission periods are used, the unit will become hot and will require an additional heatsink to be fi tted.When fi tting the me-d200/d350 into a fi xed installation, care must be taken in the routing of all cabling such that the insulation cannot become damaged.The recommended supply sources for use with the me-d200/d350 are a standard 12V supply, but is capable of operating in the range (9V - 18V).●●●Preparing for useUnpacking and inspectionUnpack the modem and check that you have received the following items:me-d200 or d350 TransceiverUser Guide (this document)me-d200 diagramme-d350 diagram:If any of these items are missing, please contact your supplier.●●e11 03466335
4 5Description of modemThe me-d200/d350 is a network free, point to point data radio that offers great fl exibility in varied applications where wireless data or voice communication is needed. It can be used as a “dumb” radio, with no internal module fi tted, to allow users to facilitate the use of their own modem and protocol. Internal link changes enable the input to be set for TTL levels so allowing POCSAG for example. In this scenario, the radio is completely transparent and simply needs the correct signal level inputs (see pin out details), and use of separate control lines (PTT etc) or serial commands.The me-d200/d350 can also be fi tted with either a Bell 202,V.23 module, a FFSK module (up to 4800 baud rate) or a GMSK module (up to 9600 baud rate). These allow communication with a pc via hyper terminal and other emulation packages. For further information on these options, including pin outs, please refer to the separate Module Manual available on the Mobile Expertise web site.The me-d200/d350 also operates as a standard radio with microphone input and speaker output, in this mode the radio has the following associated features, these include CTCSS/DCS, busy channel lockout and scanFeaturesCompact and rugged die cast boxResistant to dirt, dust and water ingress (IP54 rated)Network free, point to point communication1/5 watt programmable output powerSynthesised operation with 16 channel capabilityCTCSS & DCS encode and decodeprogrammable 12.5 / 25kHz channel spacingExternal modem / Direct FM / TTL (pocsag)Internal (RS232) module options available: GMSK up to 9600 or FFSK up to 4800 or Bell 202 V23 1200bpsRSSI level indicationBusy’ output9 – 18 volt supply inputEnhanced Power Save Mode (sleep)Serial commands available to control radioBusy Channel lockoutTime out timerScanningTX only featureProgrammable squelch levels●●●●●●●●●●●●●●●●●●●

14 15Channel selectionChannels are selected by the use of internal switches and can be set as shown below. The bottom 4 screws will need to be removed to gain access to the switches, care must be taken to avoid any damage which could invalidate the warranty.The channel can also be changed by a serial command inputted from the external control system.Figure: Setting of channel selector switch for each channelBy altering link options, channel change can also be implemented using TTL levels on pins 11,12,13 & 15 of DB15 way assuming these pins are not in use and default conditions are met. Refer to Application Notes on the Mobile Expertise web site.OperationTransmit/receive operationThe me-d200/d350 can be put into transmit by different methods. When used as a “dumb” radio, the PTT line is pulled low (pin 3 of DB15). The Tx serial command will also put the radio into transmit (pin 8 of DB15), until the Rx serial command is received. Where an internal module is fi tted the PTT/Busy links are changed to RS232 (see module manual). The GMSK and FFSK can in addition operate automatically by going into “TX” on receipt of data on pin 10 of DB15.Serial commandsThe modem can be controlled by using the serial command (pin 8) data in, sending commands to the radio such as PTT or change channelThe format for these commands (asynchronous) are:Baud rate: 4800 bit/secData: 8 bit, Parity: Non parityStop Bit (SP): 1 bitMSB fi rst transmissionEach serial command consists of 3 bytes. The fi rst byte is the command (CMD), the second is data (DATA) required by the command and the third is the check sum (CS) to validate contentsTX Command format:CMD DATA CS1st byte 2nd byte 3rd byteN.B. Check Sum = 1st byte + 2nd byte. CS = CMD + DATAResponse format:CMD DATA1 DATA2 ...

18 19 IStandard radio commands ScanningA scan function is available whereby any or all 16 channels can be monitored for activity. Scanning parameters such as scan speed and delay are programmable (refer to programming guide) Control of the scan channels is by serial commands. Note The priority channel (the transmit channel during scanning) is the channel selected via the dip switch.TimingsRadio timings parameters are available for alteration via the programmer. These include:Time-out timer,Hang timer -transmit after dis-asserting PTTTx delay - prevents squelch noise when using CTCSS/DCSBusy Channel LockoutPrevents TX when while the radio is receiving. Refer to programming guide more more detail.N.B. Where the module option board is fi tted alternative programmable functions apply.●●●Module Test Message Enable0x75 0x78 ACK / NACKModule Test Meesage Disable0x75 0x79 ACK / NACKA comprehensive list of serial commands is available on our web site www.mobile-expertise.co.uk/support
20 21Internal Module TimingsTx delay and Rx delay timings are available for alteration when the internal module is fi tted only. Please refer to the programming guide and module manual for detailsPower Save ModeThe modem will go into power save mode for short periods of time to minimise power consumption when a battery supply is being used. Parameters are programmable.Enhanced Power Save Mode (sleep)The modem in this mode deactivates all circuitry with the exception of the micro controller. It is activated and deactivated using serial commands (see Command List).Current consumption is signifi cantly reduced to approximately 7mA and represents an 85% saving on normal standby consumption.SquelchThe modem offers 2 forms of squelch, which are programmable as RSSI level check or busy port .RSSI level uses the RSSI level from the FM detector chip and the point of squelch is programmable.Noise saquelch uses the ‘on board’ circuitry to detect noise and is manually adjusted.Status indicators and Audible alertsThe LED indicates the current status of the radio and if an external speaker is connected to pin 9 of the DB-15, audible tones can be heard under certain fault conditions. The details are shown in the table opposite.●●Status Description LED colour Audible tone(if speaker fi tted)Normal Power ON Green-Orange-redBusy channel OrangeCorrect Call (with SAT) GreenTransmit RedWarning Busy channel lockout Green fl ashes beep toneTime out time Green fl ashes (ptt active)Red LED extinguishes (serieal cmd)5 secs before TOT 1 Green fl ash beep toneErrors EEPROM error 1 Orange fl ashOut of lock Continuous Orange fl ashes

Ideally, multiple antennas should be separated by a minimum of a wavelength (at the lowest frequency), whilst still retaining a good ground plane for each antenna. Therefore, for a 400MHz system, the ideal separation should be a minimum of 0.75m (~30in), and for 150MHz system the minimum should be 2.5m (~98in).Warning: If installing an antenna near people it is necessary to ensure the minimum separation is maintained. This particularly important where prolonged exposure is likely.For a full range of antenna options and other accessories visit the Mobile Expertise web site.●●●
24 25Power sourcesIt is important that a “clean” source of power is used for the supply to the modemFuse replacementWe recommend an inline “quick blow” fuse rating of 4 amps be fi tted to the +ve supply. CablingIf possible, run RF cables separately from other cables and keep RF cables apart from one another to avoid interference / coupling.When fi tting the modem into a fi xed installation care must be taken in the routing of all cabling such that the insulation cannot become damaged.FixingWe recommend that the me-d200/d350 is securely fi xed to a surface, either directly, or with a suitable bracket. The fi xing hole centre dimensions are as shown.The modem can be attached to any surface by using suitable size screws through the M3.5 holes in the mounting fl anges.52.045mm +/-0.305108.763mm +/-0.07623.5mm Clearance50.06mm +/-0.250108.763mm +/-0.0762
26 27Safety and general informationImportant information on safe and effi cient use of your Radio deviceExposure to radio frequency energyYour modem is a high power radio transceiver. When it is on, it receives and also sends out radio frequency (RF) signals. To help minimise human exposure to RF electromagnetic energy, keep transmission time to 50% or less. As with all radio devices, holding the antenna affects transmission quality and may cause the radio to operate at a higher power level than required. Do not hold the antenna when the radio is in use.Do not use radios with damaged or modifi ed antenna, this may violate compliance with relevant international standards. Where prolonged human exposure is likely, the minimum separation from the antenna should be 0.8m.Electromagnetic interference/compatibilityMost modern electronic equipment is shielded from RF energy. However certain electronic equipment may not be shielded against RF signals. The modem needs to be switched off in any facility where posted notices instruct you to do so to avoid electromagnetic interference or compatibility confl icts. Special care should be taken near facilities such as hospitals or health care centres may be using equipment that is sensitive to external RF energy.Medical devices (Pacemakers)If you use any personal medical device, consult the manufacturer of your device to determine it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this information.Vehicles with airbagsAir bags infl ate with great force. Do not place a radio in the area over an airbag or in the airbag deployment area, any radio may be propelled with great force and cause serious injury to the occupant of the vehicle.Potentially explosive atmospheresTurn off your modem prior to entering any area with a potentially explosive atmosphere, unless it is a radio type especially qualifi ed for use in such areas. Do not remove install or charge batteries in such areas. Sparks in potentially explosive atmospheres can cause an explosion or fi re resulting in bodily injury or death.Potentially explosive atmospheres include fuelling areas such as petrol stations, below decks on boats, fuel or chemical transfer or storage facilities, vehicles using liquid petroleum gas (such as propane or butane); areas where the air contains chemicals or particles such as grain, dust or metal powders, and any other area where you would normally be advised to turn off your vehicle engine. Areas with potentially explosive atmospheres are often but not always posted.
