Address and jumper settings
CAN1 termination
CAN1 has its own terminating resistor (120 ohm) directly on controllers board (PCB). Close jumper CAN R
connecting terminating resistor to CAN bus, open jumper CAN R disconnecting terminating resistor.
RS485 termination
When point-to-point is connected (eg with display), keep both Bias and termination resistors closed - default
jumper settings.
