Radio Frequency (RF) Transceiver.

The RCR 'Gold Box' incorporates the R3HNX Transceiver Board, together with its ‘companion’ RF
Power Amplifier Board.

The R3HNX Transceiver Board is a multi channel, UHF-synthesized RF receiver with a Liquid

Crystal Display (LCD). Additionally, it has a built in RF transmitter for ‘POLLING™’ data
transmission. The R3HNX receiver section incorporates a microprocessor and uses Digital Signal
Processing (DSP) techniques to selectively recover digital messages using CATTRON-THEIMEG™
protocol. The receiver section also has LED indicators for:

• Power ON

• Carrier Detect (RF signal or carrier is present)

• VCO Lock (receiver locked on freq.)

• Data (received message data)

• Q-sync (synchronization pulse)

The RF Power Amplifier Board is a high power RF amplifier that connects between the R3HNX
Transceiver Board and the Antenna Connector. An on-board LED indicator shows when trans mitted
digital RF ‘POLLING™’ data from the R3HNX transmitter is being amplified and sent to the RCT.

Opening the front door of the RCR enclosure and removing the 'Gold Box' lid will expose the R3HNX
Transceiver Board, together with its ‘companion’ RF Power Amplifier Board. Referring to Figure
1-7 and Table 1-2 below, transceiver and amplifier board LED indicators indicate system status and are
particularly useful when troubleshooting and adjusting the transceiver.
