Using the 1:1 NT Link
Compatible Host Units
Some models and series of OMRON PCs have the 1:1 NT Link function built in.
With CQM1H PCs, a Serial Communications Board can be added to provide 1:1
NT Link communications. Some C200HX/HG/HE(-Z)E CPU Units can be con-
nected by the 1:1 NT Link by installing a Communication Board.
Check the model and series of the PC against the model of CPU Unit before
making the connections.
The hosts that can be connected to the NT21 by the 1:1 NT Link using the
RS-232C ports of both Units are indicated in the table below.
