- Page 4 CAN and Digital Input Controls A five wire connector connects to the charger for interfacing with the BMS. Three wires have a white connector attached, these three wires are the CAN interface. The other two wires are labeled “+ 12V” and “- 12V”, these wires are the digital input used to control the charger from the BMS CPU.

Page 6: Troubleshooting
If both the CAN communication and the digital inputs are connected CAN communications will take priority over the digital input for charge control. CAN communications requires the optional CAN board be installed on the BMS CPU. *Caution* The BMS CPU has a programming port on it marked “Rx, Tx, RES, VSS”.
