Connection to a PC by the Host Link (RS-422A Type)
Connect the NT11S to an OMRON PC by using the RS-422A type host link meth-
od.
If the distance between the NT11S and the PC is greater than 15 m, this method
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 NT11S and PC, the ratio is 1 to 1.
In order to make a connection to the PC using the host link method (RS-422A
type), the “Comm. Type” memory switch of the NT11S must be set to the host link,
and the “Comm. Port” memory switch must be set to RS-422A. For details on
memory switch settings, see “Selecting the Host Communication Method” (page
58).

Check the model and series of the PC against the type of host link unit before mak-
ing the connections.
