This Plug-in features a new 4 pin powered CAN connector and cannot use the old CANPCB cable for CAN connection. Use the CANJST4 (Code 101-0198) cable for connecting CAN devices. This new 4 pin port and cable provide not only 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 at 3A continuous.
