N.B. The inversion of the Rx and Tx signals between the gateway and the PC is shown on the 9-point SUB-D connectors, because beyond this junction, the RS-232 signals are replaced by the D(A) and D(B) polarisations of the RS-485 signals.

6.1.2. RS-232 Link Protocol

There is no need to configure the PC’s COM port, as AbcConf uses a specific setup which replaces the one for the port being used. This replacement is temporary and is cancelled as AbcConf stops using this serial port, that is to say when AbcConf is closed.
