The compact wireless transceiver module TCM 515 from Rutronik is suitable for systems such as transceiver gateways, actuators and controllers that communicate based on the EnOcean radio standard in the sub-GHz band.
It helps reduce power consumption, comes in smaller size and a lower purchase price compared to the previous generation TCM 310, which is still available. Due to the higher processor performance of the TCM 515, all security features – encryption, decryption and authentication – can be performed directly in the module. This enables a secure end-to-end communication without external components.
The TCM 515 module, pre-certified according to international radio standards, receives radio telegrams either via wire antenna, PCB antenna or an external 50 Ohm antenna. It can filter, decrypt and authenticate these telegrams before forwarding them to an externally connected host processor or host PC via a serial UART-interface (Universal Asynchronous Receiver Transmitter).
The serial interface operates according to EnOcean ESP3 standard with the option to use higher interface speeds (TURBO mode) to reduce latencies. ESP3 messages received from the external host will be encrypted and authenticated as required before they are transmitted as EnOcean radio telegrams.
The wireless transceiver module TCM 515 / S3003-K515 supports the radio frequency 868MHz for Europe while the TCM 515U / S3053-K515 supports 902MHz for North America.
