*1: Use a CPM2C-CN111 or CS1W-CN114/118 Connecting Cable, CPM1-CIF01 RS-232C Adapter, or CPM1-CIF11
RS-422A Adapter to connect.
*2: CPU Units of CVM1/CV-series PCs without the suffix -EV

cannot be connected.
The Host Link method cannot be used when an NT21 is connected using
RS-485. To use the Host Link method, connect by RS-422A.
Settings at the Host
When using the RS-422A type Host Link method, the settings shown below must
be made at the host (depending on the Unit, some of these settings may not be
necessary, or settings not shown here may be necessary).
