Page 10: Product Overview
This document is designed for use by engineering design, installation, and maintenance personnel. General Description GeminiG3 – 700MHz is a mobile radiomodem aimed at the public safety and public utility markets to meet demand for high speed and high throughput. It integrates all the necessary hardware for data-only vehicular installations up to but not including the laptop PC and its application software. -
Page 11: Features
SRC4FSK 64 kb/s • Built as a one-piece integrated design in a rugged die-cast aluminum chassis, GeminiG3 units automatically adapt to the speed of the base station for maximum network flexibility. • Parallel Decode™ (PD) technology featuring dual receivers results in added decode sensitivity in multi-path and fading environments. -
Page 12: Configuration
Network-specific operating instructions should be prepared by the system administrators in conjunction with Dataradio system engineering. Instructions and examples given in this manual are based on GeminiG3 radiomodem operating software version 1.xx and may not apply to earlier or later software versions. -

Page 14: Installation
2.1.1 Overview To ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimum po- sition for GeminiG3 unit and its antennas 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. -
Page 15: Warnings
2.2.3 Secure mounting For vehicle occupant(s) safety, mount GeminiG3 unit securely so that the unit will not break loose in case of an accident or violent maneuvers. -
Page 16: Physical Unit
• Do not overtighten self-tapping screws. 1. Once you have found a suitable mounting position for GeminiG3 unit, hold the unit and the unat- tached 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. -
Page 17: Electrical Installation
Figure 2 - Bracket installation 5. Install the bracket without distorting 6. Securely mount GeminiG3 radiomodem 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. -

3. Place this connector at GeminiG3 radio power input location. Do not connect at this time. See para- graph 2.6, “Completing 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. -

Page 41: Gps ► Aavl
The “Autonomous Automatic Vehicle Location” (AAVL) feature adds the ability for GPS-equipped GeminiG3 units to initiate "Here I am" position message transmissions. AAVL allows the system de- signer to specify the maximum distance or the time interval between position reports: If the vehicle moves more than a specified distance since its last report, a new position report will be generated. -
Page 42: Security
The Setup web pages, the CLI (command line interface) and the FTP server all require a password to pre- vent unauthorized users from changing a unit’s configuration. At the time of manufacture, the password is set to “ADMINISTRATOR” but Dataradio strongly suggests that the password be changed as units are installed. -
