Worst-Case Power Consumption:
AUI Connector
RJ-45 Connector
---------------------------------------------------------------------------
* When the RJ-45 connector is used, the controller does not consume any
power at +12V. It passes +12V through to power any external transceiver
connected to the AUI cable.
