Internal auxiliary I/O connector

The internal auxiliary I/O connector is a 50-pin low-profile IDC connector. It is
used to transmit timing and synchronization signals, and transmit/receive
auxiliary signals. The connector is located on the edge of the board, making the
signals accessible from inside 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
independent acquisition path and the type of signals that can be routed onto it.
