• 18 pin DIP/SOIC Package
• 2 Digital Telemetry Lines (addressed mode only)
• Asynchronous Serial Host Interface
The RF600T provides a simple interface between TTL level asynchronous serial data sources and standard
RF modules (Transceiver, Transmitter or Receiver) with minimal interface required.
The RF600T performs all the necessary data manipulation and encryption required by the Radio module to
achieve a reliable radio link whilst providing a simple data interface to the users controller.
The device has been designed to obtain the maximum range from the Radio medium using automatic data
packet generation 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.
