EXTRACT FROM ACCUSPEED OPERATING INSTRUCTIONS FOR R3HNX 450 MHz UHF TRANSCEIVER & RF AMPLIFIER BOARD 09/2003, CATTRON-THEIMEG Page 1 of 4 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 transmitted 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.

The green Carrier Detect LED indicates that the receiver section is receiving a RF signal. This yellow LED indicates that the received RF message contains data. This orange LED indicates an interrupt that signifies the computer/
decoder has received a new message. This red LED (located undernneath the EMI/RFI shield) illuminates when the transceiver frequency synthesizer is unable to lock onto the required frequency. This red LED (located on the RF amplifier) flashes when the transmitted digital RF POLLING data from the R3HNX transmitter is being amplified and sent to the RCT 09/2003, CATTRON-THEIMEG Page 3 of 4 SYSTEM SUMMARY Technical Specifications LCU [RCR]
