C-series C200HS, C200HX/HG/HE (-ZE), CPM1, CQM1 CPUs, SRM1
Connect to the built-in RS-232C port of the CPU, or the RS-232C port (port A, B)
of the communication board. Note that the connection to a CPM1 must be made
via an RS-232C adapter (CPM1-CIF01).
Reference: Connection to the peripheral port of the CPU is not possible.
