Note: This plug-in has a new 4-pin CAN connector with power supply and cannot use the old CANPCB cable for the CAN connection. Use the CANJST4 cable (code 101-0198) for connecting CAN devices. This new 4-pin connector and cable not only provides the CAN connection but also a protected 12V power supply and ground for the operation of the CAN devices. The power supply is protected by a self-resetting fuse with 3A continuous load.
