WebJ1939/11 CAN bus cable are recommended by the Society of Automotive Engineers (SAE) for light and heavy-duty offroad vehicles and stationary applications utilizing vehicular-derived components such as generator sets. The J1939/11 standard defines a 250K bit/second, twisted shielded pair physical layer construction with 120 ohm characteristic ... WebJan 3, 2015 · 7. In principle you should be able to multiplex MCU CAN signal lines, prior to their being used to interface to a CAN physical layer transceiver, using something like a 74HC4052. In practice, I'd suggest that it's not a very good idea to do so. The problem is that multiplexing would mean that you are guaranteed to periodically miss ...
