Connecting to the RS-232C Port at the Host
Using the NT Link (1:N)
Method
The settings for SW1 and SW2 depend upon the usage of the
peripheral port and RS-232C port.
Setting the Switches on an RS-232C Adapter
When using a CPM1-CIF01 RS-232C Adapter, set the mode switch as shown
in the following diagram.
Set the mode setting switch to NT (lower position).

When using a CVM1/CV-series PLC, CPU Unit execution processing (execu-
tion control 2) in the PLC Setup must be set to Simultaneous processing.
Compatible Host Units
The OMRON PLCs that can be connected using the NT link (1:N) method are
the CS/CJ-series CPU Units and the C-series C200HX/HG/HE(-Z)E, CQM1H,
and SRM1 only. With the CS/CJ-series PLCs, it is possible to connect a 1:N
NT Link using a Serial Communications Board (CS Series only) or a Serial
Communications Unit.
