Connecting to the Host’s RS-422A/485 Port
Section 5-2
When Using the NT Link (1:1) Method
Compatible host units
Some models and series of OMRON PCs have the RS-422A type NT link (1:1)
function built in. There are also some C200HX/HG/HE(-ZE) CPUs that can be
connected by the RS-422A type NT link (1:1) method by installing a communica-
tion board.
Check the model and series of the PC against the type of CPU before making the
connections.
The host units that can be connected to the RS-422A port of the NT31/NT31C by
the RS-422A type NT link (1:1) method are indicated in the table below.

*2 CPUs of CVM1/CV series PCs without the suffix “-EV
” cannot be connected.
The NT link (1:1) method cannot be used using RS-485. To use the NT link (1:1)
method, connect by RS-422A.
NT link connection using RS-422A is not possible with CPM1.
