CAN_L and CAN_H are the same

[WIPER]

Hello,

I have a PCI-CAN/LS2 in my PC desktop and I'm trying to communicate with EPOS2 controller to move a MAXON EC40 motor.

I reached to read a CAN message trought my PCI-CAN card but I can't send a message correctly. To understand what the problem is, I have measured CAN_L and CAN_H wires with my oscilloscope and they look verry similar. Even more, when I display the difference between the two signals I have 0 and a little bit noise... I made this experience with the can_transmit_periodic_wf2.vi example.

I think my PCI-CAN card send the same messages on CAN_L and CAN_H.I think it's a configuration problem.

I've seen on internet that there exist a single wire CAN but it's looks not to be an option I can configure.

Does have anyone an idea?
