Connect
to the built-in RS-232C port of the CPU Unit, or the RS-232C port of
the
Communication Board. Note that the connection to a peripheral port must be
made
via an RS-232C Adapter (CS1W
-CN1

-
ing to a peripheral port.
PC Setup
When
connecting to a CS/CJ-series CPU Unit, set the following
communication
conditions
for the PC Setup. Since the settings shown below are
the PC default
settings
for the CPU Unit, no change to the PC Setup is necessary as long as
the
baud rate is maintained at 9,600 bps.
Item Setting at Host
Baud rate Set the same speed as set at the NT21
(*1)
Stop bits 2 stop bits
Parity Even
Data length ASCII 7 bits
Unit No. for the Host Link 00
*1 Set the Host Link baud rate at 9,600 bps or 19,200 bps with the memory switch
at the NT21. For details, refer to Settings the Host Link Method (page 127).
When the baud rate is set to 19,200 bps, the PC Setup of the CPU Unit need to
be changed.
Either set the PC Setup directly from a Programming Device (Programming
Console), or transmit the PC Setup made at a Programming Device (CX-Pro-
grammer) to the CPU Unit.
For details on PC Setup, refer to the SYSMAC CS Series Operation Manual
(W339-E1-j) or SYSMAC CJ Series Operation Manual (W393-E1-j).
