Trailblazer Installation and User Manual version 1.03 4 2.1 Site Requirements and System Planning 2.1.1 Grounding A ground is a low impedance electrical connection to earth that is used to dissipate energy. Grounding your Trailblazer is very important for safety reasons as well as to protect your system from damage due to lightning and static charge build up. Since lightning strikes and surges follow the path of least resistance, all ground wires must be as short and straight as possible and not be coiled or looped. Choose the largest diameter ground wire your ground connectors will accept for good electrical conductivity. Recommended grounds are: the utility company ground, a ground rod, well casings, and cold water pipes that are of continuous metal. A note of caution: sometimes the metal-cold water pipes are repaired and/or extended with PVC piping hidden behind drywall. The introduction of PVC material disrupts the material’s conductivity and thus renders it unacceptable as a ground. Unacceptable grounds are: sprinkler pipes, PVC pipes, conduit, buried wire, and any ground that cannot be verified. 2.1.2 Lightning Protection Lightning protection with a poor ground is the same as having no protection at all! Lightning is one of the most dangerous and unfortunately most frequently encountered natural hazards to your Trailblazer. Ensure that your system is adequately protected. A good connection to ground is indispensable for your lightning protection to work correctly and thus preventing lighting and surge damage to your Trailblazer. The Trailblazer system is equipped with on-board secondary active lightning protection only. The lightning protection is only effective when the system is powered up. If you power down your Trailblazer, disconnect the antennas and phone lines to prevent damage from lightning strikes. Install primary lightning protection with a good ground on all RF, data/voice line connections that have even a moderate outdoor line build out. A good rule of thumb is that all lines entering or exiting a building need protection. Both ends of the cables between buildings must be protected! See section 5.2 for detailed specifications and usage information on primary lightning protection available from Carlson Wireless. 2.1.3 Line of Sight: Is it enough? Visual line of sight (LOS) is the straight, unobstructed line between the Base unit’s antenna and the CPE’s antenna. In other words, when you stand next to one antenna, you can see the other one. Because RF waves spread out three dimensionally rather than in a straight line, LOS is important in microwave transmission but not adequate. As the waves travel out from the transmitting antenna, the signal density decreases and more three dimensional space around the visual LOS is necessary to be able to receive

Trailblazer Installation and User Manual version 1.03 5 a reasonable signal at the receiving antenna. This three dimensional space is called the RF LOS or Fresnel zone for the French physicist who first discovered its importance. 2.1.4 Fresnel Zone: What it is in plain English! The Fresnel zone is the tree dimensional cone around the line-of-sight that radio waves spread out into after they leave the antenna. The cross section of the first Fresnel zone is circular; subsequent zones’ cross sections are annular. The signal strength is strongest in zone 1 and decreases in each successive zone. Not only trees, buildings and mountains can occupy a Fresnel Zone, the curvature of the earth, even for some short paths, also has to be taken into consideration. A rule of thumb is that 60% of the first Fresnel zone must be free of any obstructions for tolerable attenuation of the signal. In addition to absorbing the RF signal, objects in the RF path can also reflect it, making the signal out of phase with the original signal, and effectively causing signal cancellation. In zone 1 the signal will be 0 to 90o out of phase in zone 2, 90 to 270o in zone 3, 270 to 450o and so on. Even numbered zones have the maximum phase canceling effect and in odd numbered zones the reflected waves will add to the signal.

Each system is shipped with a handy, full-color “Quick Start Guide” for simplified step-by-step instructions for bench testing. The following section will provide you with the same information in greater detail. 2.3.1 Setting up Your Trailblazer on the Bench Set your units next to each other and attach the included test antennas to the N female connectors on the enclosures as shown. The units may not achieve an RF connection without these little antennas. 2.3.2 Powering the Trailblazer The Trailblazer units accept 12 -24VDC negative ground. There are special provisions for using a positive ground, please contact your CWT sales representative for more information. If your system is equipped with a battery backup, verify that the battery output is 12VDC or more. If the battery output is less than 12VDC, disconnect the power supply’s black and red power cables, connected to the terminal block, from your unit, and simply connect the power supply’s terminated red (+) and black (-) power cables to their respective terminals on the battery. Plug the AC power supply cable into an AC source to charge the battery, and verify that the battery is charging. Ensure that the battery is fully charged before proceeding into the field. When the battery is fully charged, verify that the unit powers up by noting that the LEDs are lit. Test Antennas

Trailblazer Installation and User Manual version 1.03 10 Figure 2: Base Unit Power Connections If you are not using the CWT power supply, size your power supply adequately using Ohm’s law. For example, if you provide 12VDC you consume 2/12 A or about 167mA. If you provide 24VDC you use about half of that or 85mA. CWT recommends providing at least 4 times the power consumption. The Trailblazer consumes 2 Watts. CWT’s power supply with battery backup supplies 13.8VDC @ 1 A or 14 Watts. You can also power your Trailblazer by using several of the unused voice/data pairs in a standard 6 pair telephone cable. Don’t forget to allow for additional current if add-on card options are selected. The standard 6 pair telephone cable is made of 22 AWG size copper. This means that both legs will have 3.2 ohms of resistance per 100 feet. The table below shows the distance at which you have a 5% maximum recommended voltage drop using 2 pairs of wires paralleled together.

Trailblazer Installation and User Manual version 1.03 20 Preceding future integration of these functions into the GUI software, some system configurations must be performed on a manual text entry level. To do this, you can interface with the Trailblazer radio card using either the GUI software on the Terminal screen (See Section 3.1.3) or by using the HyperTerminal™ software. You will also need to add a 50ms delay to the linefeed in your terminal ASCII settings in order to send text commands to the Trailblazer radio through terminal software. See the screenshot (right) for an example. Begin by starting the GUI or making sure your terminal software is loaded and properly configured to communicate with the Trailblazer radios. See Section 6.4 for configuration instructions. Each setting is controlled by a short “command name” followed by an EEprom register or “switch” designated by a letter or letters on your screen. Type the command name for the function you wish to implement followed by the appropriate “switch” and press enter. The Trailblazer radio card should respond by echoing the new setting back to you. It usually takes (7) sets of these commands to configure a radio card for any of its many functional states. The settings may be changed one at a time or combined in a text file, known as a “script”, and loaded into the Trailblazer radio card. See the following table for details and examples. Write to EEprom register EEprom register 0=Star 8=P2P # of Total Ch. wee e Write to EEprom register EEprom register # of Data Channels wee f 0 Write to EEprom register EEprom register # of Data Ch. # of Voice Ch.

Trailblazer Installation and User Manual version 1.03 21 To set for Star topology or Point-to-Point and Bandwidth of the Base unit: This is set using the EEprom register “E”. If the first digit of the switch setting or “most significant digit” is an “8” then it is planned to be in point-to-point mode. If the first is “0” or none then it will be in Star mode. The second digit or “least significant digit” is for the bandwidth (as transmitted from the base unit) with the number corresponding to how many 64 kb channels are made available. For example, type in though Hyper terminal or the GUI window [wee e 84] The system should respond back with [000E: 84] This will set up a Point to Point with 256 kb available bandwidth. Entering [wee e 08] would set the radio to be a Star with 512 kb bandwidth. To allocate total data Bandwidth of the base unit: To allocate data channels in 64kbps increments, EEprom register “F” is the total number of data channels allocated to the Base unit. To allocate total data Bandwidth of the CPE terminal: To allocate channels to the CPE stations, the EEprom registers 10,11,12,13 are used. This will handle up to (4) CPEs in a star configuration. In the CPE, EEprom registers 10,11,12,13 the MSB is used to state the amount of 64kb channels bonded for data. The LSB is used to state the number of 64kb channels available for voice services. See the following table for some example scripts.

Do not over tighten! 4.2 External Antennas The use of an external antenna with Model Trailblazer RC Pro system mandates professionally trained personnel to ensure compliance with FCC rules and regulations. Specifically the installer must ensure that the EIRP of the transmitting antenna does not exceed the requirements of the Code of Federal Regulations, Title 47, Part 90 subpart m.

Trailblazer Installation and User Manual version 1.03 25 This device has been designed to operate with the antenna listed below, and having a maximum gain of 16 dB. Antennas not included in this list or having a gain greater than 16 dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. WARNING! YOU CAN BE KILLED! The Trailblazer system is designed to be installed by professionally trained installers only! Failure to follow basic installation procedures and safety precautions can result in one or all of: damage to tools and/or equipment, interference with and/or damage to other equipment or accessories, violation of safety code, local laws and/or building codes, personal injury or even death. Detached antennas, whether installed indoors or out, should be installed ONLY by experienced antenna installation professionals who are familiar with local building and safety codes and, wherever applicable, are licensed by the appropriate government regulatory authorities. Failure to do so may void the CWT product warranty and may expose the end user to legal and financial liabilities." "Regulations regarding maximum antenna gains vary from country to country. It is the responsibility of the end user to operate within the limits of these regulations and to ensure that the professional installer is aware of these regulations, as well. " Installations of the Trailblazer System require topographic analysis, site survey, and link budget calculation; therefore CWT trained professionals are required to perform the installation. 4.2.1 Marketing and Sales Channels CWT DOES NOT sell the Trailblazer PRO direct to end users. i WLL Trailblazer PRO System will be sold only to CWT's Authorized Resellers. Those authorized resellers are technically trained by CWT's Engineers periodically and must follow the rules set by CWT. The Trailblazer PRO system is designed for Long Range (15-35 miles) applications and it involves a complicated mandatory site survey, roof top mast installation, high gain antennas, accurate antenna alignment, etc. Those activities can be done ONLY by professional installers that are familiar with the FCC regulations. CWT does not sell the Trailblazer PRO in the consumer business at all. We have no resellers in this market and we do not advertise in consumers based publications or attend consumer oriented trade shows. The system will be advertised in technical trade shows and magazines. 4.2.2 Calculating the EIRP of an External Antenna For the 5.8 – 5.9GHz bands of frequency, the output of the Trailblazer TB series radio is calibrated at the factory to limit the peak power output to +7dBm.

Trailblazer Installation and User Manual version 1.03 26 Using this example one can calculate the following: Note that the radio is calibrated for a maximum output power of +7dBm. Subtract the interconnecting cable and lightning protection losses of 2dB = total power arriving to antenna of 15dBm. . For 5.8 – 5.9GHz, the FCC allows a maximum EIRP of 23dBm. This would mean that an antenna with a gain of 16dBi would be acceptable with no cable losses. Following this guideline ensures compliance with the maximum transmitter ERP allowed with the antenna provided as a system. 4.2.3 RF Safety Hazard Warning Due to the substantial energy radiated from these antennas, it is imperative that they never be mounted such that the antenna or the cabinet containing the antenna will be closer than 2 Meters (6.7 Feet) to any persons.

Trailblazer Installation and User Manual version 1.03 29 This is a properly mounted sector antenna. Note the ability of the mount the aim the antenna uptilt, downtilt and to either side.

Trailblazer Installation and User Manual version 1.03 30 4.4 Weatherproofing RF Connections Once you have the antenna mounted and secured. Complete the installation by properly attaching the weatherproof cables. 4.5 Antenna Alignment Rough alignment: This is fairly straight forward. Since it is a prerequisite that you have line of sight between the two points, here are several ideas that have worked for installers:  If you can see the other unit, simply aim the units towards each other.  During midday, use a mirror or compact disk to create a reflection approximately towards the other site while someone watches for the flash.  Plot out the path on a topographical map and set the antennas using a compass. How close in alignment do they need to be? +/- 6 degrees will be adequate for most paths using the 16 dB gain antenna. Certain paths that have a low fade margin may require a more accurate setting. Alignment indicators: Due to the nature of digital modulation and the associated circuitry, there is no analog test point at which the signal strength may be monitored. Rather, the bit error rate is indicated on the digital board. If there are obstructions or interference in the link the middle, red LED will begin to blink. The rate of flash is an indication of the degree of signal degradation, with a higher flash rate indicating more errors. Final alignment is performed by connecting a standard telephone directly to the CPE terminal (FXS) and listening to the dial tone. As the antenna is moved to the left the signal will degrade, the bit error LED will flash, and eventually the link will be lost. Note where the antenna is aimed when the link is lost and rotate the antenna to the other side until the signal is lost again. The midpoint between the positions where the signal was lost indicates the best antenna position. Use the GUI software and a laptop to determine the exact signal peak and then tighten the antenna mounts. 4.6 Interference Solutions Sometimes after installation, final alignment is found to interfere with external devices, and/or external devices are later installed that affect the Carlson Wireless Radio device. To determine if the Carlson Wireless radio is an interferer, power down the radio unit and check if the interference is removed. To determine if an external device is interfering with the Carlson Wireless radio, shut down suspected devices while listening to an audible tone (such as dial tone) on a phone connected through the Carlson Wireless system.

Trailblazer Installation and User Manual version 1.03 31 Common Interferers are: microwave, wireless household controls, emergency radio equipment, cordless telephones, wireless video products, etc. (refer to Interference Section Error! Reference source not found. for more information) Before calling the manufacturer the installer is encouraged to try correcting the problem by trying one or more of the following suggestions:  Slightly reorient or move the Carlson Wireless antenna to a new position  Change the frequency of Carlson Wireless radio or offending device  Relocate the offending/offended device  Separate power sources, or filter sources between the offenders  If not installer, consult dealer or experienced technician 4.7 Lightning Protection CWT stocks in-line, gas-discharge style lightning surge suppressors as primary lightning protection for their reliability, ease of installation and low cost to the customer. In-line protectors mount in series with the coaxial cable or telephone line which provides an excellent solution for a retrofit application. The protector is grounded through an external ground screw that is attached to the body of the surge protector. Be sure to take the other end of this ground circuit into consideration as well. 4.7.1 Antenna Port Protection Mount the CWT in-line, gas discharge lightning surge suppressor in parallel with the coaxial cable between the radio and the antenna. Place the protector as near the radio as possible in order to limit the amount of cable that will be exposed to either direct or indirect strikes of lightning or atmospheric static charges. Connect the largest wire (usually #8 or #10AWG solid) to the ground screw on the body of the surge protector and terminate it to a proper ground (see above). If you have any question about the quality of your ground system, stop and remedy the issue before continuing.

Trailblazer Installation and User Manual version 1.03 43 6.4 Advanced Programming and Diagnostics 6.4.1 Configuring the Serial Port Parameters In order to communicate with the Trailblazer units using the Command Line Interface, the serial port parameters need to be configured. The serial port parameters are illustrated in the following figure. These settings were configured within the program by Hilgraeve (see left and below). This program is readily available and runs on any Windows platform, but any terminal emulation program can be used that can communicate across the asynchronous serial COM ports of a PC. The ASCII setup screen in HyperTerminal™ needs to be configured as well in order to properly communicate with the Trailblazer units. In addition to the basic ASCII setup (shown right) which you will use most to configure the system, you must insert a 50ms line delay in order to be able to send scripts to the Trailblazer units. Scripts are what you will need to use in order to configure the amount of and allocation of bandwidth within the Trailblazer system. See Section 3.4 Allocating Bandwidth to Voice and/or Data for complete details.

Trailblazer Installation and User Manual version 1.03 44 6.4.2 Setting the V35 enable and port location To enable the V35 data port, open up the Hyperterminal™ interface and if you are communicating with a CPE unit after booting type: [stop]. If you are connected to a base unit it will stop on it’s own after a minute. Then type in: [wee 5 1] or [wee 5 2] depending on which line no you wish to be used as a data path for the Ethernet connection. The system should respond back with: 0005: 02 as shown above. To disable theV35 data port, open up the HyperTerminal™ interface and type in: [wee 5 FF] . The system should respond back with: 0005: FF . 6.4.3 Received Signal Strength Indicator (RSSI) The RSSI value can be accessed through the Command Line Interface using the following command: rdm ff28 4 <enter>. The figure at right shows the output for the RSSI from the CPE unit. The RSSI value is repeated 4 times, but just look at a single number. The figure to the right shows an RSSI of 0C. The RSSI should be 8 or higher. If the value displayed contains an alphabetic character (A, B, C, D, E or F), the value is greater than 9. The undesirable RSSI values are from 00 to 07. The RSSI command can be used on the base unit. The above figure displays the results of the command. 3 of the 4 values will always read 00, just ignore these values. 1 of the 4 numbers should be greater than 7. If the value displayed contains an alphabetic

Trailblazer Installation and User Manual version 1.03 45 character (A, B, C, D, E or F), the value is greater than 9. In the above example the RSSI value is sufficient. 6.4.4 Air Link Quality The quality of the Air Link can be interrogated through the Command Line Interface using the following command: debug 1 <enter>. This command causes the Air Link statistics to be printed every 4 seconds. The statistics can be stopped by typing, debug 0 <enter>. The processing of the debug command is illustrated in the following figure. With a completely clean link, the SFD Loss Count and Signal Byte Error Count should be both zero. A SFD Loss Count greater than (6) could indicate a low signal strength or external interference. 6.4.5 Installation of Software/Firmware Upgrades In addition to maintenance using the GUI software, as a failsafe the software/firmware for the Trailblazer systems can be upgraded in the field through the serial port using a terminal emulation program and the Command Line Interface. 1. Reset the board using the RESET button near the rotary channel switch. 2. Stop the program through the Command Line Interface. The figure above illustrates this step. When the Boot program starts, the software version information is displayed. When the prompt “Boot Loader Ready” appears, type: [stop] and press: <enter>. The Boot program confirms the stop command by displaying the text “Boot Loader Stopped”. If the text “Boot Loader Stopped” is not displayed immediately, RESET the unit and try again. Although timing is not extremely critical, try to type the command in the first couple of seconds.

Trailblazer Installation and User Manual version 1.03 46 3. Download the new software/firmware program. The following two figures illustrate this step. The menu option “Send Text File …” is selected. Next, the dialog box will appear which allows the selection of the file to download to the Trailblazer unit. After the file is selected, click the “Open” button. The download will proceed automatically from this point. 4. Download has completed. The end of the download is illustrated below. The version information at the end of the download will indicate the successful completion of the download. Re-display the version information again by typing <versions>. 5. Reset the board either manually using the reset button or by typing <reset>. The Trailblazer unit will need to be reset before the new software/firmware upgrade will take effect.
