Using the High-speed 1:N NT Links
Compatible Host Units
Only
the -V1 versions of the CS1-series CS1G/H, CS1-H-series CS1G/H-H, and
CJ-series CJ1G PCs support the high-speed 1:N NT Links directly. Other CS/
CJ-series
PCs can use the high-speed 1:N NT Links indirectly through a CS1W
-
SCU21
or CJ1W
-SCU41 Serial Communications Unit. (If a Serial Communica
-
tions Unit is used, even CS1-series Units without the “-V1” suffix can be con-
nected via high-speed 1:N NT Links.)
Be sure to check the model number of the PC and Serial Communications
Board/Unit before trying to establish the high-speed 1:N NT Links.
The
following table shows which CS1-series PCs can be connected to an NT21
with the high-speed 1:N NT Links.

The Settings required for each Unit are described below.
• Connecting CS/CJ-series CPU Units
CS-series CPU Unit model: CS1G/H-CPUjj-EV1, CS1G/H-CPUjjH

PC Setup
When
connecting to a CS/CJ-series CPU Unit, set the following
communication
conditions for the PC Setup, in accordance with the communication port to be
used.
When using the built-in RS-232C port of a CS1G/H, CS1G/H-H, or CJ1G
