PC Bus Connectors

 The 6 pin connector has the following pinout:
Pin 1; Power, 30volts
Pin 2; Ground
Pins 3, 4; B Twisted pair (-/+)
Pins 5, 6; A Twisted pair (-/+)
Cable shield
 Pins 3/4 are crossed with pins 5/6 at the opposite ends of the cable.
 The transmitter sends clock [Strobe] on 3/4, and data on 5/6.
Some cards may require jumper setting to supply output voltage.
