You need to have total 60 ohm resistance in the CAN network (between the can H and CAN L).
The MCP board has a 120 ohm jumper on it. Make sure it's connected. On the other end where the module is connected, put 120 ohm resistor between CAN H and CAN L.
The unit must receive a configuration message to wake up and enable the functions.
