doors and window columns that are convenient to run cables and wires. Whenever possible, install conduit in which to run the cables. 2. Installation 2.1 Planning the Installation 2.1.1 Overview 2.2 To ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimum position for G3 and its antennas as well as the routing of all associated cabling and wiring. Before starting installation, review all of the following warnings. 2.2.1 RF Radiation warning 2.1.
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.
1. Once you have found a suitable mounting 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 distorted when installed. 7. Drill any additional holes as required for routing all cables and fit holes with suitable grommets or bushings whenever required. 2.4 2.4.
The DC Power connector has: • • • 6. Repeat the step above for connecting the red DC power lead. At position “A”, the smaller red switch-sense wire (commonly to ignition) At position “B”, the blue ground wire At position “C”, a larger red B+ DC power wire (MUST be unswitched) 13.8VDC B+ (Fused Red wire) GROUND (Blue wire) 7. Attach the positive lead at the battery positive terminal. Attach the negative wire at the vehicle end of the battery ground cable.
2.5 Antenna 2.2.1 ≥5/8λ The main transmitter antenna must be vehicle-mounted to provide a separation distance of 50 cm or more from all persons to avoid radio related effects (see 2.2.1). 800MHz: 9"/23cm 50cm 19.7in. 2.5.1 Recommended tools and supplies • • T R ≥24in. G circle cutter, hole saw or socket punch for antenna Mini-UHF Crimp tool 2.5.2 Planning Referring to Figure 4, G3 commonly uses three separate antennas: • “T” - Main transceiver Constraints are the limit of 50 cm (see section 2.
2.5.3 Antenna Installation 2.6. Completing the physical Installation. 1. Route good quality 50-ohm coaxial cables (e.g. RG-223) from each of the selected antenna positions to the position where the G3 unit is mounted. To complete the physical installation and prior to testing G3 : 2. Terminate the end at each of the antenna positions with the appropriate connector for the antenna used and make the connection. 3. At the G3 position, cut the three cables to length and terminate with the appropriate plug.
3. Operating Description 3.1 Front & Rear Panels The front panel includes: • One mini-UHF type female antenna connector for the auxiliary receiver • One SMA type female connector for the GPS receiver • Three LED indicators • Two DE-9F RS232 ports • One USB port • Onr RJ45 Ethernet port The rear panel includes: • One mini-UHF type female antenna connector for the main transceiver • One 3-pin pigtailed DC Power connector with ignition sense ® G3 RX PWR PGM RX LNK ACT TX 2.

4. Trouble-Shooting and Testing The checks described below should be done at annual intervals or whenever deterioration in performance is noted. 4.1 • • • • • Equipment Required 13.8 VDC (nominal) car battery, or 13.8 VDC/20A regulated power supply (In the case the unit is not installed in a vehicle) In-line watt meter (50W range) Radio service monitor (IFR or equivalent). Cable with mini-UHF male connector to connect G3 to the service monitor. Dataradio test commands script version 0.01* 4.
Table 2 - Tests STEP ACTION CHECKLIST A EXPECTED RESULTS at 25°C MEASURE WITH IF NOT? G3 units are set and characterized at the factory to optimize performances. It is not recommended to try to readjust the units.
4.3 Additional test details 4.3.1 GPS Test 4.3.2 RF Data Link 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 satellites to arrive at a ground position solution. A link test between a mobile and a known base station can be done using the Dataradio test commands "Address" and "Send" test commands.
