Note: RS-232 signals use positive and negative voltages to represent digital 1s and 0s. A positive voltage is a 0, and a
negative voltage is a digital 1.
This pin-out enables the radio to be directly connected to a computer’s 9-pin serial port using a
conventional 9-pin RS-232 serial cable. To connect it to a modem, or computer peripheral that has a
serial port, a “null-modem” cable is required. See Appendix A for more information on wiring a null-
modem cable.
To configure the M7 modem for RS-232 operation, use the ATIO 0 command. RS-232 is the default
operation mode for the connector. RS-485 is a factory option. See the next section for details on the
RS-485 option.
