I've got a circuit with a CAN bus connector like the following with two RJ11 connectors to be connected in a daisy-chain style:
But only one of them is working (I tested them by connecting to another terminal node with a single connector). The soldering is correct.
When I measured the resistance between CANH and CANL with a jumper on each end, the working connector resistance was 60 ohms as expected, but'll be 120 ohms when connected to the not-working connector or with both connected. What'll be the problem in this case?
