  • Page 11: Command Mode

    RF73 User Guide Command mode The command mode is used to read and update the modem configuration registers using AT command. In command mode the radio reception and transmission is inhibited. Entering command mode: The command mode is entered by issuing a +++ sequence on the serial link.

    RF73 User Guide • ‘O’<cr><lf> (ASCII character 0x4f,0x0d,0x0a) for accepted command (meaning OK) • ‘E’<cr><lf> (ASCII character 0x45,0x0d,0x0a) for error (meaning ERROR) Transceiver mode In transceiver mode, two protocols are available: • Transparent protocol • Addressed protocol The communication is always half-duplex. The radio transmission is processed prior to the radio reception (when the transceiver is sending a radio frame, it is not able to decode any incoming radio frame).

  • Page 13: Transparent Mode

    RF73 User Guide Transparent mode In transparent mode, the modem acts as a wired serial link. It means that alternately, the modem sends on the radio the data received from the serial link and sends on the serial link the data received from the radio. The radio frame format is : •...
  • Page 14 RF73 User Guide Processing incoming RS232 data: the incoming RS232 data are internally buffered. The buffered data are sent in a radio frame (the RF modulation is started) when almost one of the following conditions occurs: when a break (silence greater than S217 timeout) is detected on the incoming serial flow (no more data to be sent).
