Hardware Features
The RF600T provides a simple interface between TTL level asynchronous serial data sources and standard
RF modules (Transceiver, Transmitter or Receiver). The device allows for either broadcast or addressed point
to point modes of operation and is simple to use with minimal interface required. Data packet generation is
automatically performed along with ‘Manchester’ encoding and CRC based error checking. In addition, in
addressed mode, automatic retries ensure that the host is informed of successful or failed data packet
delivery. The RF600T uses control lines to handle the flow of data to and from the host, and incorporates a
190 byte data buffer.
