Connecting to the RS-232C Port at the Host
Section 4-1
When Using the NT Link (1:N) Method
S Compatible host units
The OMRON PCs that can be connected using the NT link (1:N) method are
CS1 series CS1G/H and C series C200HX/HG/HE (–Z) only.
Check the model and series of the PC against the type of CPU or communica-
tions board before making the connections.
The host units that can be connected to the NT31/NT31C by the NT link (1:N)
method using the RS-232C ports of both units are indicated in the table below.

[PC system setting area settings]
Write the communication conditions directly to the “PC system setting area”
(data memory) using a peripheral tool (e.g. SYSMAC support software).
For details on setting the “PC system setting area settings”, refer to the “SYS-
MAC C200HX/HG/HE (-ZE) Programming Manual” (W303-E1-j).
Make the settings in the words shown below according to the port used.
