CAN networks require THREE wires. CAN_L, CAN_H, and a signal Common.
CAN voltage level detection is differential (the difference between CAN_H and CAN_L),
those voltages are both measured with respect to the common wire.

When you are presented with 2-conductor + shield, connect the shield to the CAN_GND terminal.

CAN specification has become the basis for a wide number of industry and manufacture specific variants.............

AU5790 also known as "Single Wire CAN" is a low power, low speed physical layer that is used in automotive applications
and an increasing number of industrial applications. It employs the AU5790 transceiver.
AU5790 Converts interfaces with buffers capable of running high speed CAN to connect with systems using the AU5790 transceiver.

Is that canbus is your spec? Maybe with 2 wire you can use RS485.
