GeminiPD Installation Guide

1. PRODUCT OVERVIEW

1.2.1 Features:

This document provides the information
required for the installation, operation and
verification of the

DATARADIO

Gemini

mobile radiomodem.

1.1 Intended Audience

This document is designed for use by engi­neering design, installation, and mainte­nance personnel.

1.2 General Description

GeminiPD is a mobile radiomodem aimed at
the public safety and public utility markets to
meet demand for high speed and hig h
throughput. It integrates all the necessary
hardware for data-only vehicular installations
up to but not including the laptop PC and its
application software.
Example of applications are:

1. Database inquiry systems.
Small number of brief messages, (usu­ally from the mobile station) with fairly
long responses.

2. Computer-aided dispatch (CAD).
Large number of messages, (usually
from the base station) with very brief
responses.

3. Automatic Vehicle Location (AVL).
Using built-in GPS receiver, determines
position, speed and direction of fleet
members.

The Gemini
transceiver and an auxiliary receiver for
Parallel Decode (PD), a 40-Watt power
amplifier (35-Watt for 800 MHz m odel), a
Gemini Control Unit (GCU ) w ith D SP driven
modem and an integrated OEM GPS
receiver.

PD

is made-up of a main

• One-piece integrated design in a rugged

PD

die-cast aluminum chassis.

• Parallel Decode (PD) technology fea-

turing 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 im-

proved roaming capabilities.

• Built–in 16-channel synthesized radio

transceiver.

• Power output of 10W to 40W (software

controlled).

• Data speeds of 9600 to 19200 b/s

(9600 b/s maximum in half channels)

• 3 available user ports using standard

RS-232 interface

• Half-duplex or simplex operation.

• Built-in GPS receiver.

• Out-of-band signaling enables transmis-

sion of GPS reports with no effect on
system performance.

• Back-compatible with MobilPac/R

1.2.2 Configuration

GeminiPD is factory configured based on
each customer network system require­ments, usually by Dataradio System Engi­neering. Configuration is not changeable in
the field without notifying Dataradio.

1.5 Replacement Parts

This product is not field serviceable, except
by the replacement of a complete unit. Spe­cialized equipment and training is required
to repair the GCU board and radio modules.

Contact Technical Support for service in­formation before returning equipment. A
Technical Support representative may sug­gest a solution eliminating the need to return
equipment.

1.5.1 Factory Repair

When returning equipment for repair, you
must request an RMA (Returned Material
Authorization) number. The Tech Support
representative will ask you several questions
to clearly identify the problem. Please give
the representative the name of a contact per­son who is familiar with the problem,
should questions arise during servicing of
the unit.

Customers are responsible for shipping
charges for returned units. Units in warranty
will be repaired free of charge unless there
is evidence of abuse or damage beyond the
terms of the warranty. Units out of warranty
will be subject to service charges. Informa­tion about these charges is available from
Technical Support.

1.4 Product Warranty

Warranty information may be obtained by
contacting your sales representative.

2. 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 Gemini
antennas as well as the routing of all associ­ated cabling and wiring.

PD

and its

ignition circuits to help prevent interference
between these components and radio
equipment.
Try using existing holes in firewall and
trunk wall and the channels above and be­low or beneath the doors, channels through
doors and window columns that are con­venient to run cables and wires.
Whenever possible, install conduit in which
to run the cables.

2.2 Warnings

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 Gemini
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

Gemini

PD

is not fully waterproof, therefore
it should be mounted sufficiently away from
an opened trunk lid or opened tailgate, win­dows 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.

Before starting installation, review all of the
following warnings.

2.2.1 RF Radiation warning

The Federal Communications Commission
(FCC), with its action in the General
Docket, 79-144, March 13, 1985, has
adopted a safety standard for the human ex­posure to radio frequency electromagnetic
energy emitted by FCC-regulated equip­ment. Only proper installation of the trans­ceiver antenna of Gemini
in paragraph 2.5 through 2.5.3 will result in
user exposure substantially below the FCC
recommended limits.

Antennas installation must be done by quali­fied personnel. See paragraph 2.5 for rec­ommended antenna positioning.

Transmissions when persons or animals out­side the vehicle are within two feet of the
antenna may result in radio energy radiation
burns or related injuries.

PD

as summarized

2.1.3 Cable Path

Try to route the cables away from locations
where they would be exposed to heat (ex­haust pipes, mufflers, tailpipes, etc.), battery
acid, sharp edges, mechanical damage or
where they would be a nuisance to automo­bile mechanics, the driver or the passengers.
Keep wiring away from automotive com­puter modules, other electronic modules and

2.2.2 Interference with vehicular
electronics

Certain vehicle electronic devices may be
prone to malfunction due to lack of protec­tion 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
