Procedure (Connecting Multiple NetSure™ SM-DU+ Assemblies Together)
NOTE!
The NCU can communicate with up to eight (8) NetSure™ SM-DU+ assemblies. Set each NetSure™ SM-DU+
assembly to a unique address number.
1.
To connect multiple NetSure™ 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 4.4 for an interconnect diagram.
2.
Connect a termination resistor such as P/N 561768 to the last NetSure™ 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 4.4.
