3-4-8 One-to-one PC Link Connections

A CPM1A can be linked to a CPM1A, CQM1, CPM1, CPM2A, CPM2C, SRM1(-V2), C200HS or C200HX/HG/HE PC through an RS-232C Adapter. One PC acts as the Master and the other as the Slave to link up to 256 bits in the LR area (LR 0000 to LR 1515).

Note One-to-one PC connections can only be used when the RS-232C Adapter (CPM1-CIF01) is connected.

Set the DIP switch of the RS-232C Adapter (CPM1-CIF01) to the NT (bottom) side.

The following diagram shows the wiring in the RS-232C cable used to connect a CPM1A to another PC.
