Internal auxiliary I/O connector

The internal auxiliary I/O connector is a 50-pin low-profile IDC connector. This
connector is used to transmit/receive communication and auxiliary signals; the
auxiliary signals can be used to route data valid, field, timer clock, 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 all of these signals from outside the computer enclosure.
The pinout for this connector is as follows. Refer to the description of the external
auxiliary I/O connectors to establish if an auxiliary signal is specific to an
acquisition path and the type of signals that can be routed onto it.
