Connector Assignments
5.2 CAN-Networks without Electrical Isolation
In the following the connector pin assignment of the CAN interfaces CAN 2, CAN 3 and CAN 1
without electrical isolation is shown. CAN 1 is not electrically isolated from the other networks in
the CAN-Repeater versions without “-Opto” design (C.1330.02 and C.1330.03).
CAN 3 is only available in the CAN-Repeater-Y versions (C.1330.03 and C.1330.07)
