4.3. DIP Switch Settings
The WRC-CANR-DF has an 8-pole DIP switch.
•
Switch positions 1-4 are used to set the baud rate of the CANR on which it is located
(the local unit).
•
Switch positions 5-8 are used to set the baud rate on the CANR at the other end of
the fiber cable (the Remote Device).
The baud rates can be set independently, or one side can take its baud rate from the other side
(in the “Remote” setting).
The Autobaud detects from DeviceNet bauds.
For CANopen speeds, select the fix baudrate setting.
When both the CANR units are set to all open switch positions (remote-remote) it scans through
DeviceNet baudrates.
