Internal auxiliary I/O connector

The internal auxiliary I/O connector is a 50-pin low-profile IDC connector. lt is
used to transmit/receive the camera control, timing, and auxiliary signals. The
auxiliary signals can be used to route synchronization, trigger, exposure, or
user-defined signals.
The connector is located on the edge of the board, making the signals accessible
from inside the computer enclosure. You can use the connectors on the adapter
board to access most of these signals from outside the computer enclosure; only
the most commonly used signals are accessible so that an easily sourced connector
of a reasonable size can be used. Note that the clock signals are not accessible from
the adapter board.
The pins for auxiliary signals carry unidirectional signals, unlike those for
synchronization signals on the DVI connector. This means that using this
connector, the board can both transmit and receive synchronization signals at the
same time.
All the signals are LVTTL signals unless otherwise specified. Note that the clock
and synchronization signals are the LVTTL version of those on the DVI
connectors.
