RS-422 Host Device Connection
For the RS-422 connection between the host device and ID Controller, refer to RS-422 Connections.
p.30
If RS-232C communications are used first by the ID Controller, receiving RS-422/RS-485 communications will be pro-
hibited. If RS-422/RS-485 communications are used first by the ID Controller, receiving RS-232C communications will
be prohibited. It is thus necessary to turn OFF the power supply before changing the ID Controller system configuration.
■ RS-485 Host Device Connection
Note: Using RS-485 is possible by shorting pins 1 and 3 and pins 2 and 4, and changing the setting to RS-485.
For the RS-485 connection between the host device and ID Controller, refer to RS-485 Connections.
