Procedure (Connecting Multiple SM-DU+ Assemblies Together)
NOTE!
The NCU can communicate with up to eight (8) SM-DU+ assemblies. Set each SM-DU+
assembly to a unique address number.
1. To connect multiple SM-DU+ assemblies together, for all assemblies connect the CAN_H terminals
together and connect the CAN_L terminals together (CAN_H to CAN_H, CAN_L to CAN_L). See
Figure
7 for an interconnect diagram.
2. Connect a termination resistor such as P/N 561768 to the last SM-DU+ assembly in the NCU CAN bus.
Connect to CAN_H and CAN_L terminals along with the CAN_H and CAN_L leads factory connected to
the terminal block. See
Figure 7 .
