Notes:

• The connector needs to be tightened properly to make a proper connection, ensuring reliable operation.

• Each end of the CAN bus must be terminated with a 120 Ohm resistor across CAN H & CAN L.

• Do not short-circuit any pins.

• The maximum safe applied voltage for analogue and digital I/P is ±28 V.
