156 90000-508 G3 Installation Guide 32. Installation 2.1 Planning the Installation 2.1.1 Overview To ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimum position for G3 and its an-tennas as well as the routing of all associated cabling and wiring. 2.1.2 Location Often, installations in cars are done in the trunk, underneath the back window ledge or on the trunk floor. In vans and small trucks, it is usually done in the back of the vehicle. In large vehicles, it is often done in the front cabin. Be sure to place the G3 unit in such a way that: • The LEDs can be seen (as an aid in troubleshooting) • Access to the antenna DE-9 connectors is possible without removing the unit • Sufficient air may flow around the unit to provide adequate cooling G3 is not fully waterproof, therefore it should be mounted sufficiently away from an opened trunk lid or opened tailgate, win-dows or doors to avoid exposure to rain and/or snow. It also minimizes the chance that material can be accidentally thrown on the unit or of someone bumping against it. 2.1.3 Cable Path Try to route the cables away from locations where they would be exposed to heat (ex-haust pipes, mufflers, tailpipes, etc.), battery acid, sharp edges, mechanical damage or where they would be a nuisance to automo-bile mechanics, the driver or the passengers. Keep wiring away from automotive com-puter modules, other electronic modules and ignition circuits to help prevent interference between these components and radio equip-ment. Try using existing holes in firewall and trunk wall and the channels above and be-low or beneath the doors, channels through doors and window columns that are conven-ient to run cables and wires. Whenever possible, install conduit in which to run the cables. 2.2 Warnings Before starting installation, review all of the following warnings. 2.2.1 RF Radiation warning Qualified personnel must do all antenna in-stallations. See paragraph 2.5.2 for recom-mended antenna positioning. Transmissions when persons or animals out-side the vehicle are within two feet of the antenna may result in radio energy radiation burns or related injuries. 2.2.2 Interference with vehicular electronics Certain vehicle electronic devices may be prone to malfunction due to lack of protec-tion from radio frequency energy present when transmitting. It includes, and is not limited to: - Electronic fuel injection systems - Electronic anti-skid braking systems - Electronic cruise control systems If the installation vehicle contains such equipment, consult the dealer for the make of vehicle and enlist his aid in determining if such electronic circuits will perform nor-mally when the radio is transmitting. 2.2.3 Secure mounting For vehicle occupant(s) safety, mount G3 securely so that the unit will not break loose in case of an accident or violent maneuvers. 2.2.4 Explosive environments Operation of vehicular radio transmitters in explosive environments may be hazardous and conventional safety precautions must prevail. These include and are not limited to: - Transmitting while fuelling the vehicle. Do not carry fuel containers in the same compartment as G3 .
156 90000-508 G3 Installation Guide 4- Dynamite blasting caps may explode when transmitting radio operation takes place within 500 feet. Always obey the “Turn Off Two-Way Radios” signs posted at sites where dynamite is being used. If transporting blasting caps: a) Carry the blasting caps in an appropriate metal container having a soft cushioning lining. b) Suppress transmissions whenever the blasting caps container is being loaded or unloaded into or from the vehicle. Check applicable local bylaws. 2.2.5 Installation in vehicles pow-ered by liquefied gas. G3 installations in vehicles powered by liquefied petroleum gas with the LP-gas container in the trunk or other sealed-off space within the interior of the vehicle must conform to the National Fire Protection As-sociation Standard NFPA 58 which requires: - Space containing radio equipment shall be isolated by a seal from the space con-taining the LP-gas container and its fit-tings. - Outside filling connections shall be used for the LP-gas container. The LP-gas container space shall be vented to the outside of the vehicle. 2.3 Physical Unit 2.3.1 Recommended tools and supplies • Electric drill for mounting holes • Hammer and center punch • Tie-wraps • Drills and circle cutters as needed ac-cording the size of screws (or nuts and bolts) used. • In-line “Power meter” capable of meas-uring forward and reflected power at the operating frequency of the radio. 2.3.2 Physical mounting of G3 Start by running all the cables (DC power, PC RS-232, USB or RJ45 as well as all an-tennas cabling) prior to mounting G3 to assure the feasibility of the planned cable routing. Be sure to leave sufficient slack in each cable so the G3 may be removed from the mounting bracket for servicing with the power applied and the antenna at-tached. G3 is ready for installation. Cautions: • When drilling mounting holes, be careful to avoid dam-aging some vital part of the ve-hicle such as fuel tanks, trans-mission housing etc. Always check how far the mounting screws extend below the mount-ing surface prior to installation. • Use of drill bit stops is highly recommended. • After drilling, remove all metal shavings before installing screws. • Do not overtighten self-tapping screws.
156 90000-508 G3 Installation Guide 51. Once you have found a suitable mount-ing position for G3 , hold the unit and the unattached mounting bracket in the proposed mounting position and check that there is clearance behind the unit for the heatsink, cables, etc. Check that the position provides a large enough flat surface that the bracket will not be dis-torted when installed. Figure 1 - Mounting plate and slot dimensions 2. Using the installation bracket as a tem-plate, mark the four locations for drilling (see Figure 1). Again, ensure that drill-ing at the selected points is safe and will not cause damage. 3. Indent the drilling positions with a cen-ter punch. 4. Drill holes sized for the self-tapping screws or for the nuts, bolts and lock washers used. Caution: Slightly reduce the size of the drilled holes when using self-tapping screws in thin metal. Figure 2 - Bracket installation 5. Install the bracket without distorting. 6. Securely mount G3 to the installed bracket using the four supplied 8x40 black machine screws. 7. Drill any additional holes as required for routing all cables and fit holes with suitable grommets or bushings whenever required. 2.4 Electrical installation 2.4.1 Electrical requirements G3 is designed to operate from a 13.8Vdc nominal car battery (negative ground) and requires currents up to 15.0A. It will tolerate a supply voltage range of 10.9 volts to 16.3 volts. In vehicles with a 24 VDC electrical system (mostly in trucks), it is essential to provide a suitably rated 24/12 VDC converter to iso-late the unit from the battery and protect it against excessive voltage. Warnings: Always disconnect G3 ’s DC power lead before connecting a second battery, using power from another vehicle or power boosting (e.g. when “jump starting” the vehicle). 2.4.2 Routing of power cable 1. Start by disconnecting the vehicle’s bat-tery unless specifically prohibited from doing so by the customer, vehicle manu-facturer, agent or supplier. Note: In this event, exercise ex-treme caution throughout the installation and fit the fuse only when the installa-tion is complete. 2. The 22 feet (6.7 meters) long power ca-ble consists of three wires attached to a Packard Electric “Weather-Pack” con-nector (DC power Connector). 2.5"6.0"1.0"0.2"
156 90000-508 G3 Installation Guide 6The DC Power connector has: • At position “A”, the smaller red switch-sense wire (commonly to igni-tion) • At position “B”, the blue ground wire • At position “C”, a larger red B+ DC power wire (MUST be unswitched) Figure 3 - DC Power Connector 3. Place this connector at G3 ’s radio power input location. Do not connect at this time. See paragraph 2.6, “Complet-ing the physical installation”. 4. Carefully route both the B and the C wires to where the in-line fuse holder will be installed, usually as close to the vehicle’s battery as practicable. Ensure that leads do not chafe on any metal part(s). Secure the wires at several loca-tions along their length. Caution: Use proper crimping tool. Common pliers are NOT acceptable. Warning: The DC Power lead must be unswitched 5. Insert the negative (blue) lead into one of the appropriate connector lug and crimp solidly to force the metal contacts onto the wires. 6. Repeat the step above for connecting the red DC power lead. 7. Attach the positive lead at the battery positive terminal. Attach the negative wire at the vehicle end of the battery ground cable. If the negative cable is con-nected directly to the battery negative terminal, it should be fused in case of failure of the ve-hicle’s ground cable. Ensure tight and secure connections. 8. Fasten the fuse holder and leads. 9. Carefully route the A wire to where the connection will be made for switch sensing. • Connect to “Ignition” if you wish to have G3 turning ON and OFF de-pendent on the vehicle’s ignition key. • Connect to “Accessory” if you wish G3 to be available when the en-gine is not running, but still depend-ent on the ignition key. • Connect to a user-supplied control switch. • In installations equipped with a “ChargeGuard”, connect to the con-trolled-side of the ChargeGuard (remembering that the DC Power lead must NOT be switched). 10. Make appropriate connections. Cautions: Where scraping to bare metal was required, and at the battery posts where wire ends and lugs may be exposed, apply anti-corrosion com-pound. Insert the fuse only when installa-tion is complete and ready to test. 11. At the G3 position, neatly coil cable slack and attach securely.

For the optimum antenna spacing at the fre-quency you are using, consult System Engi-neering. For installation of ground-plane dependent antennas, the center of the metal surface used for mounting is preferable for best omni-directional pattern. For ground-plane independent antennas, installation may be close to the edges of the surface. Figure 4 - Antenna spacing Install the antennas in one of the following positions: - Most preferred for all antennas: center-line of roof. For transmitter antenna, it is the ONLY acceptable position. - Less preferred for receiver antenna: trunk lid, providing distance to transmit-ting antenna is respected whether lid is opened or closed. - Much less preferred, but permissible for receiver antenna: left or right rear fend-ers, just in back of rear window - Least preferred, but permissible for re-ceiver antenna: left or right front fend-ers, ahead of windshield Note: Proximity to other vehicle-mounted antennas may cause mutual inter-ference especially at higher fre-quencies.
156 90000-508 G3 Installation Guide 82.5.3 Antenna Installation 1. Route good quality 50-ohm coaxial ca-bles (e.g. RG-223) from each of the se-lected antenna positions to the position where the G3 unit is mounted. 2. Terminate the end at each of the antenna positions with the appropriate connector for the antenna used and make the con-nection. 3. At the G3 position, cut the three ca-bles to length and terminate with the ap-propriate plug. For the transceiver and the auxiliary cables, use a Mini-UHF crimp plug using an appropriate crimp-ing tool. For the GPS, use a SMA con-nector. 4. Positively identify the transceiver mini-UHF plug and connect to the left rear of G3 . 5. Positively identify the auxiliary receiver mini-UHF plug and connect to the front left of G3 to the RX position. 6. Connect the SMA connector to the GPS* position below the auxiliary con-nector position. 7. Do not skip this last step, trust us; it is an important one. To complete the in-stallation, tie-wrap together the auxiliary and the GPS antenna cables at a point about two inches in front of the unit. It will be much easier hereafter to cor-rectly identify which mini-UHF plug goes where. You DO NOT want to cross the auxiliary plug with the transceiver plug. 2.6. Completing the physical Installation. To complete the physical installation and prior to testing G3 : • Connect DC Power cable’s connector to G3 ’s until you hear a click as the two parts snap together. • Re-check that all other connections are secure (antennas, PC, etc.) • Switch vehicle ignition ON. You are now ready to check for normal op-eration and to run Dataradio test commands for testing or trouble-shooting. 2.7. Checking out Normal operation Check that the vehicle ignition is ON. 1. Check for proper operation of the G3 ’s LEDs as per Table 1 in section 3.1 2. Using the Dataradio test commands pro-gram and an in-line wattmeter, check forward & reverse power to confirm main antenna installation (as per section 4). 3. Using Dataradio test commands, check the RF Data Link with a base station that can be heard (as per section 4.3.2. If user application and its base station are available, test the installation by going through a normal sequence of transmitting and receiving messages.

156-90000-508 G3 Installation Guide 13 4.3 Additional test details 4.3.1 GPS Test About three minutes after ignition is turned-on, the PWR LED on the G3 front panel should flash in amber color at the rate of one pulse per second. This indicates that the GPS has acquired the sky position of a sufficient number of satel-lites to arrive at a ground position solution. If the GPS has a good view of the sky and still has not generated any position solution within three minutes (it may take up to 10 minutes or more if the sky view is partially blocked.), the following trouble-shooting procedures should be undertaken to isolate the fault: 1) Disconnect the GPS antenna cable connector from the G3 radio and check for + 5 VDC on the center pin of the GPS antenna connector on the radio using a Digital voltmeter (DVM). If the voltage is present, do not re-connect the cable and proceed to step 2. 2) With the DVM, measure resistance between the shell and the center conductor of the GPS cable, resistance should be between 100 and 300 Ohms, if it measures open or short circuit the GPS antenna is either a passive antenna which is the WRONG type, or a defective ac-tive antenna, replace with a known good ac-tive antenna. 3) Connect the new antenna to G3 and wait about three minutes for the POSITION ACQUIRED indicator to start flashing on G3 , if not, the G3 radio or its GPS receiver is defective 4.3.2 RF Data Link Test A link test between a mobile and a known base station can be done using the Dataradio test commands "Address" and "Send" test com-mands. The “Address” and “Device” fields, the “Send” button and the “Chat” message screen are used to send messages to specific mobile or base or to carry out RF test. Start by entering the address of the mobile (or base station) you wish to send a test message to or test: 1- Specify the address: Addresses may be entered by typing directly in the “Address” field in two ways: - Numerically, the valid address range is 1-126. - As an “Alpha-Mapped-Nibble” (AMN) ad-dress, consisting of upper case letters in the range A-P. The valid address range is A to GN. - The base address is usually: 1. - The program may display one of the follow-ing messages on the status bar: - For Paragon products: “address is not in AMN or number format” - For mobile products: “address is not in the range A – GN” In either case, check that the address entered is within the acceptable range, is of a valid format and correctly typed. 2- Enter the Device number for mobile (or base station). 3- Press the Send button. The Chat window reports “Sent to xx mobile” (where xx is mobile name). If test is successful: Status line reports “Delivery confirmed. If test unsuccessful: Chat window reports “Waiting”, Then the Status line reports “Delivery Failed”.
