Connecting to the Host’s RS-422A/485 Port
Section 5-2
When Using the NT Link (1:N) Method
Compatible host units
The OMRON PCs that can be connected using the RS-422A/485 type NT link
(1:N) method are C-series C200HX/HG/HE-ZE models only. A communication
board must be installed to make the connection.
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 RS-232C port of the NT31/NT31C by
the RS-422A type NT link (1:N) function via a convertor are indicated in the table
below.

Settings at the host
- C-series C200HX/HG/HE(-ZE)
[PC system setting area settings]
Write the communication conditions directly into 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) Operation Manual (W303/W322).
Make the setting indicated in the word shown below.
