The CXT and CXR modules provide simple 'on/off' control functions without the need for additional microprocessors or remote control chips. The modules include a single function controller/actuator implemented in the firmware, allowing for latched or momentary outputs.

Detailed pin descriptions for both CXT and CXR modules are provided, including power supply, ground, transmit/receive enable, and serial programming pins.

• Frequency stability: ±1.5kHz, channel spacing: 25kHz, number of channels: 32.
• Operating temperature: -20 ºC to +55 ºC, storage: -30 ºC to +70 ºC.
• Transmitter output power: +10dBm to +20dBm, modulation type: 2.5kbps FSK.
• Receiver sensitivity: -115dBm for <0.1% data errors, AF bandwidth: 4kHz.

Programming is done via a 2400 baud CMOS level inverted RS232 format. Commands include setting channel numbers, unit addresses, and register values.

The CXR module includes a wide range RSSI for assessing link quality. Recommended antennas include whip, helical, and loop types, each with specific performance characteristics.

Various models are available for different frequency bands and power levels, with options for both VHF and UHF bands.
