Reference
Connect the NT30/30C to an OMRON PC by using the RS-422A Host Link meth-
od.
If the distance between the NT30/30C and the PC is greater than 15 m, this meth-
od should be used. The maximum distance over which a connection can be
made is 500 m.
When using the RS-422A method, the host computer and PC are usually con-
nected in a 1 to N ratio (more than one PC), but in the special case of the connec-
tion between the NT30/30C and PC, the ratio is 1 to 1.
In order to make a connection to the PC using the Host Link method (RS-422A),
the host communications memory switch of the NT30/30C must be set to Host
Link, and the port memory switch must be set to RS-422A. For details on memory
switch settings, see Selecting the Host Communication Method (page 85) and
Selecting the Host Link Communication Port (page 87).
The terminating resistance setting on the NT30/NT30C (DIP switch 2 pin 8) must
also be set to ON.
Some models and series of OMRON PCs have the Host Link function built in.
Check the model and series of the PC and the model of the Board or Unit before
making the connections.
The Units that can be connected to the NT30/NT30C’s RS-422A port as the host,
and have RS-422A Host Link functionality are listed in the table below.

• With CS1-series and CQM1H PCs, Host Link communications are possible by
• With C200HX/HG/HE PCs, there are some CPU Units that support Host Link
• With CPM2A and CPM2C PCs, connection to the NT30/NT30C can be made
nect the RS-422A terminal block of the NT30/NT30C to the RS-232C connec-
tor of the CPU Unit, Host Link Unit, or SRM1. In this case, set the communica-
tions method for the NT30/NT30C to RS-422A and the communications
method of the PC to RS-232C. For details of the connection method, refer to
the manual provided with the RS-232C/RS-422A Link Adapter.
