External auxiliary I/O connector 0
External auxiliary I/O connector 0 is a high-density D-subminiature 44-pin
(DBHD-44
*
) female connector, located on the bracket of the cable adapter board.
It is used to transmit timing and synchronization signals, and transmit/receive
auxiliary signals. It interfaces with the 50-pin internal auxiliary I/O connector on
the board, making the I/O signals accessible outside the computer enclosure.
The pinout for this connector is as follows.
*. Sometimes referred to as DB-44, but more accurately known as DE-44.
