Connecting an NT631/NT631C and Host (RS-422A)
Connecting to the Host’s RS-422A/485 Port
Direct Connection between RS-422A Ports at Both Units
The following are the communications conditions that can be used with the
memory link method. For the host (a personal computer, an FA computer,
etc.), its setting should be compatible to one of the communications condi-
tions listed in the following table. Set the same communications conditions at
the NT631/NT631C by the memory switch. (page 160).
The connection method in which the RS-422A ports of an NT631/NT631C
and a host are connected is described here.
