Thanks to a higher processor performance, 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 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.
