3.3.2. CAN 485

The CAN 485 connector contains both isolated CAN and non-isolated RS-485 (Modbus) connections.
Isolated CAN requires 5.5-12 Vdc sourced from an external power supply to operate. 120 Ω
termination for CAN is added by connecting pins 3 and 9 together. 150 Ω termination for Modbus is
added by connecting pins 6 and 12 together.
Keep the termination wire length short for best results. Connect external equipment to this connector.
