Page 2 of 4 09/2003, CATTRON-THEIMEG™ 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. Information to the User regarding FCC Compliance:Changes or modifications not expressly approved by the manufacture could void the user's authority tooperate the equipment.This device complies with Part 15 of the FCC Rules. Operation is subject to the following twoconditions; (1) this device may not cause harmful interference, and (2) this device must accept anyinterference received, including interference that may cause undesired operation.RF Exposure Information:Installation of this RF device requires the antenna to be mounted in a manner that ensures a 36cmminimum separation distance from the end user(s).

R3HNX Transceiver & RF Amplifier Board LED Indicators LED Description Transceiver Power This red LED indicates the presence of DC power on the transceiver circuit board. Carrier Detect The green Carrier Detect LED indicates that the receiver section is receiving a RF signal. Data This yellow LED indicates that the received RF message contains data. Q-Sync This orange LED indicates an interrupt that signifies the computer/ decoder has received a new message. VCO Lock This red LED (located undernneath the EMI/RFI shield) illuminates when the transceiver frequency synthesizer is unable to lock onto the required frequency. RF Power LED 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
