    SAE J1939 defines five layers in the 7-layer OSI network model,

    and this includes the CAN 2.0b specification (using only the
    29-bit/”extended” identifier) for the physical and data-link layers.
    Under J1939/11 and J1939/15 the baud rate is specified as 250 kbit/s,
    with J1939/14 specifing 500 kbit/s. The session and presentation
    layers are not part of the specification.

    I would start by looking for an adapter. This would allow you to then say use a Serial or parallel port connection and poll the device at a specfic band rate.
