The TokenLink adapter interfaces to Type 1 data grade media through
a 9-pin D subminiature connector.  The connector is wired as follows:

   Pin 1           RCV +
   Pin 6           RCV -
   Pin 5           XMIT +
   Pin 9           XMIT -
   Pin 2, 4, 7, 8  GND
   Pin 3           +5V at 150ma Max

The transmit output waveform conforms to the IEEE 802.5
specification except for the signal rise and fall time, which
conforms to the IBM specification in the Token Ring Network
Architecture Reference.
