The CTA88 chip is a simple encoder/decoder for use with ISM band telemetry modules. It permits a simple, one way wireless link to be established, for simple remote control applications, with a minimum of effort and no customer software input.
hese simple application boards use the firmware and signalling protocols of the existing CTX/CRX module products, interfaced with a choice of SIL package radio modules. A single relay output is provided, controlled by a pair of logic (or switch) inputs on the transmitter. Latched or momentary operation are selectable.
application boards constitute a bidirectional Mesh networked remote control system. Each board has 1-input, 1-output, a 4-bit global address and a 4-bit Unit ID (hence "M1144"). A complete system consists of a master board (which initiates communication burst cycles) and up to 15 slave units.
