Connect to the built-in RS-232C port of the CPU Unit, or the RS-232C port of
the Communications Board. Note that the connection to a peripheral port
must be made via an RS-232C Adapter (CS1W-CN118) specially designed
for connecting to a peripheral port.
PLC Setup
When connecting to a CS/CJ-series CPU Unit, set the following communica-
tions conditions for the PLC Setup. Since the settings shown below are the
PLC default settings for the CPU Unit, no change to the PLC Setup is neces-
sary as long as the baud rate is maintained at 9,600 bps.
Note Set the Host Link baud rate up to 115,200 bps with the memory switch at the
NT20. When the baud rate is set to 19,200 bps, the PLC Setup of the CPU
Unit need to be changed.
Either set the PLC Setup directly from a Programming Device (Programming
Console), or transmit the PLC Setup made at a Programming Device (CX-
Programmer) to the CPU Unit.
For details on PLC Setup, refer to the SYSMAC CS Series Operation Manual
(W339-E1- @ ) or SYSMAC CJ Series Operation Manual (W393-E1- @ ).
