4-1 Connecting to the RS-232C Port at the Host
The
method for connecting directly between the RS-232C port of the PT and the
RS-232C port of the host is as follows.
The
following discussion
is focused on the connection method to OMRON PCs
(By
using the memory link
method, a connection can be made to any arbitrary
RS-232C device.)

Connection between RS-232C Ports with RS-232C
Cable (Page

This
is the easiest connection method. Depending on the host to which the con

nection
is to be made, it may be possible to use OMRON cables with connectors.

Reference: The
CS/CJ-series CPU Unit cannot be connected with the 1:1 connection NT
link
method.
Use the 1:N connection NT link method instead of making the 1:1 con
-
nection.
For details, refer to
Using the 1:N NT Link
(page
55) or
Using the High-
speed 1:N NT Link (page 60).
4-1-1 Host Types and Settings
The
types of host that can be connected to a PT by using the RS-232C ports of
both devices, and the settings to be made at the host, are described here.
Using the Host Link Method
Some models and series of OMRON PCs have the Host Link function built in.
In
the CS-series (including the CS1-H PCs), CJ-series, and CQM1H PCs, the
Host
Link method can be used by installing a Serial Communications Board or
Unit.
In addition, some C200HX/HG/HE(-Z)E have an integral CPU
Unit that can
be connected in the Host Link method by installing a Communication Board.
Check
the model and series of the PC, the
type of installed Serial Communica
-
tions
Board, Serial Communications Unit, or Host Link
Unit before making a con
-
nection.
