Eclipse2 Technical Manual, 3-Aug-12 Page 5 of 17
Although there are no dangerous mains voltages present within the equipment,
the following general safety precautions as would normally apply, should be
observed during all phases of operation, service and repair of this equipment.
AROUND THE EQUIPMENT
To minimise any possible shock hazard from an external power supply or
lightning strike, the chassis or equipment cabinet must be connected to an
electrical ground. Provide adequate ventilation around the rear of the
equipment.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the equipment in the presence of flammable gases or fumes.
Operation of any electrical equipment in such an environment constitutes a
definite safety hazard.
DO NOT ATTEMPT INTERNAL SERVICE HILE TRANSMITTING
Thermal or R burns may result from touching certain components within the
power amplifier module while transmitting or operating the transmitter.
DO NOT SUBSTITUTE PARTS OR MODIFY THE EQUIPMENT
Because of the danger of introducing additional hazards, do not install
substitute or lower voltage parts to the equipment. Return to your authorised
distributor.
EXERCISE CAUTION AND CORRECT DISPOSAL OF RF PO ER DEVICES
Most R power transistors and some R power hybrids contain Beryllium Oxide.
Although they are normally safe, if physically damaged toxic dust may be
released. Consult your local authority for correct disposal thereof.

Introduction
The Eclipse2 series is a Base Station designed for Conventional Analogue M and Conventional
APCO P25 modes of operation. Internally, it is driven by software, allowing future firmware
releases to track the development of radio standards and add new modes.
Based on a DSP and RISC platform, the base station has a modular design, which provides
extensive flexibility for users. or example, it may act as a standalone transmitter/receiver, cross-
band repeater, and more. The built-in Ethernet port allows remote monitoring and control of all
operating parameters. Under software control, the centre-frequency can be arbitrarily tuned
across a band, within the limits of the installed receiver and transmitter submodules. A range of
available submodules allows The Eclipse2 system to cover most of the band from 66MHz to
941MHz.
A typical base station or repeater system includes a Reciter (Receiver & Exciter); an R power
amplifier; and a switch mode or linear power supply. All the modules can be plugged into an R
Technology standard 19 inch wide, 4U high, rackframe.
The Reciter can deliver enough R output power to be useful as a point-to-point link, meaning an
external power amplifier may not be required in some configurations. This allows up to six Reciters
to be mounted into a single 19 inch rack.

Ethernet:
The RJ45 Ethernet connector is used for networking the base station via IP protocol, a PC can use
this connector to monitor and control the base station locally or remotely.
The Reciter supports the 10/100Mbs specification (defined by IEEE802.3u) and the MDI/MDI-X
auto crossover function which means either a straight though or crossover cable can be used to
connect the base station.
There are two LEDs embedded in the RJ45 Ethernet connector, the green LED indicates that the
Ethernet link is active; the yellow LED indicates TX/RX status between the base station and the
network.
RF input:
The receiver R input connector: 50ohm female, N type.
RF output:
The exciter R output connector: 50ohm female SMA or Optional N type.
RS232 and external reference clock (optional)
The female D shell, 9-pin connector is an optional interface to the transceiver. RS232 and external

Programming and monitoring
Programming and monitoring is accomplished using the IP Commander Software. This software is
based on the Java platform and can be run under various operation systems on the host computer,
it provides a number of useful facilities for the configuration and monitoring of the base station.
The IP Commander software allows configuring of the base station (e.g. the channel frequency,
output power, signal path, etc.) without hardware alignment, it also provides a simple means of
calibrating the R power, RSSI level, audio line levels. or more details of IP Commander software,
please refer the document: RFT Doc No. 0305917801 (IP Commander User Man al).
There are two interfaces which can be used for connecting a computer and the Reciter:
