1. PRODUCT OVERVIEW This document provides the information required for the installation, operation, and verification of the DATARADIO G3. 1.1 Intended Audience This document is designed for use by engineering design, installation, and maintenance personnel. 1.2 General Description G3 is a mobile radiomodem aimed at the public safety and public utility markets to meet demand for high speed and high throughput.
1.2.1 Features • • • • • • One-piece integrated design in a rugged die-cast aluminum chassis. Parallel Decode™ (PD) technology featuring dual receivers for added decode sensitivity in multi-path and fading environments. Sophisticated DSP-based modem design provides added system performance, fewer retries and more effective throughput. Automatic channel changing for improved roaming capabilities. Built–in, up to 16-channel flash-programmable synthesized radio transceiver with automatic channel selection.

1.6 Unpacking When ready for installation, carefully unpack your G3 kit (p/n 023 6000-101) shipping carton and identify each item as listed below: • One G3 • Installation mounting bracket • Power cable – 22 feet (6.7 meters) • Small parts kit If damage has occurred to the equipment during shipment, file a claim with the carrier immediately. 2. Installation 2.1 Planning the Installation 2.1.
2.2 Warnings Before starting installation, review all of the following warnings. 2.2.1 RF Radiation warning Recommended safety guidelines for the human exposure to radio frequency electromagnetic energy are contained in the Canadian Safety Code 6 and the Federal Communications Commission (FCC) Bulletin 65. Proper installation of the transceiver antenna of G3 as summarized in section 2.5 will result in user exposure substantially below the recommended limits for the general public.
• 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 according the size of screws (or nuts and bolts) used. In-line “Power meter” capable of measuring forward and reflected power at the operating frequency of the radio. 2.3.
Figure 2 - Bracket installation 5. Install the bracket without distorting (see Figure 2). 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 12.0A.
3. Place this connector at G3’s radio power input location. Do not connect at this time. See paragraph 2.6, “Completing the physical install ation”. 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 locations along their length. Caution: Use proper crimping tool. Common pliers are NOT acceptable.
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 2.5 above) and omni-directional factors • “R” - Auxiliary receiver – Constraints are the receiver spacing of at least 5/8 λ (wavelength) from transceiver antenna and omni-directional requirements • “G” - Global Positioning System (GPS) Constraints are TX spacing of at least 24-in/60.96 cm from all transmitting antennas and a clear view of the sky.
2.5.3 Antenna 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. 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. For the transceiver and the auxiliary cables, use a Mini-UHF crimp plug using an appropriate crimping tool.

4. Trouble-Shooting and Testing The checks described below should be done at annual intervals or whenever deterioration in performance is noted. 4.1 • • • • • 4.2 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. WinRIS version 4.
