2-4-3 Settings for each Unit
*1 The RS-232C port of the Communication Board.
*2 The RS-232C port of the Serial Communication Board.
*3 is the set value of the communication speed. Set the communication speed to the same value as that of
the NB Unit.
*4 Standard settings of the Communication conditions are as follows:
Start bit: 1 bit, Data bit: 7 bit, Stop bit: 2 bit, parity check: even
For RS-422A
*1 The RS-422A port of the Communication Board
*2 The RS-422A port of the Serial Communication Board
*3 is the set value of the communication speed. Set the communication speed to the same value as that of
the NB Unit.

For operations on [PLC System Settings Area], refer to the manual of the PLC employed.
Connection methods for CPM2C
CPM2C only has a connector with the same shape of the CS-Series’ peripheral port, but the signal
cables inside are classified as used for the RS-232C port built in the CPU Unit and for the peripheral
port. Therefore, when using CPM2C, differentiate between the settings for the RS-232C port built in the
CPU and for the peripheral port based on the conversion cable and port employed to ensure correct
use. Besides, when using a simple communication device (CPM2C-CIF21 type), connect to the RS-
232C port. For details, refer to the CPM2C Operation Manual (W356).
Use a self-made connection cable to connect the NB Unit and CPM2C. Connect to CPM2C’s built-in
RS-232C port instead of the peripheral port.
When using a simple communication device (CPM2C-CIF21 type), connect to the RS-232C port
directly.
