A notice:

This plug-in features a new 4-pin powered CAN connector and cannot use the old CANPCB cable for CAN connection. Use the CANJST4 cable (code 101-0198) to connect CAN devices. This new 4-pin connector and cable not only provide the CAN connection but also a protected 12V power supply and ground for powering the CAN devices. The power supply is protected by a self-resetting fuse rated for 3A continuous current.
