Multi-channel 25kHz NBFM Remote Control Receiver

The CXT transmitter and CXR receiver modules offer a multi channel, low power, and reliable remote control data link. This makes the CXT/CXR pair ideally suited to those low power applications where existing wideband modules have insufficient range, or where low cost multi-channel operation is needed without compromising on RF specification or regulatory requirement.There are certain user applications where a very simple ‘on/off’ control function is needed (for example: control of floodlights, alarm sounders, machine override shutdown). Normally such applications require a simple microprocessor or dedicated remote control chip to be added to the radio module, incurring extra size, cost and sometimes software overhead.
Not anymore. The CXT and CXR module pair (based on either LMT2/LMR2 (UHF version) or LMT1/LMR1 (VHF version)) includes a simple-to-use single function controller/actuator, implemented in the firmware of the radio’s internal processor. This code allows the unit to be used as a very simple remote control product, with either a latched or a momentary output. No external control device is required.
