EnOcean Transceiver Module TCM 120
The transceiver module TCM 120 of EnOcean enables
the realization of bi-directional RF applications based
on the innovative EnOcean radio technology.
Typical applications are bi-directional EnOcean compatible
radio interfaces, e.g. to existing system solutions or bus
systems.
The TCM 120 transceiver module serves the 868 MHz air interface protocol of EnOcean. It receives
all signals from EnOcean radio transmitters and makes them available at the serial port. Control
signals can be sent to any EnOcean radio receiver (based on e.g. receiver modules RCM 110, RCM
120, TCM 120). The integrated modem functionality allows easy data transfer between different
TCM 120.
