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.)
Direct Connection between RS-232C Ports with RS-232C Cable (Page 77)
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.

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).
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.
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.
