The following are the communications conditions that can be used in 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 NT31/NT31C by the memory switch. (page 166).

The method for connection between the RS-232C ports of the NT31/NT31C
and the host is described here.
Recommended Connector Cable
When making the connector cable, as far as possible use the recommended
