78
CS1 series CPU type : CS1G/H–CPU
Connect to the built–in RS–232C port of the CPU, or the RS–232C port of the com-
munication 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 pe-
ripheral port.
S PC system settings
When connecting to a CS1 series CPU, set the following communication condi-
tions for the PC system setting area. Since the settings shown below are the PC
default settings for the CPU, no change to the PC system setting is necessary as
long as the communication speed is maintained at 9600 bps.

*1: Set the host link communications speed at 9600 bps or 19200 bps with the
memory switch at the NT631/NT631C. For details, refer to "Settings the Host
Link Method" (page 174).
When the communication speed is set to 19200 bps., the PC system settings
of the CPU need to be changed.
Either set the PC system settings directly from a peripheral tool (programming
console), or transmit the PC system settings made at a peripheral tool (CX–Pro-
grammer) to the CPU.
For details on PC system settings, refer to the "SYSMAC CS1 Series Operation
Manual" (W339-E1-
