Configurator Connector
The configurator connector is a 9-pin female sub-D connector.
The pin assignment of this connector is the same as the that of the RS-232C
port provided on most C200H-series CPUs. This enables the use of the same
serial communication cable for both the CPU and the C200HW-PRM21.
The wiring of the RS-232C cable is shown in the picture below.
