140 Appendix B: Technical information
External auxiliary I/O connector 1
External auxiliary I/O connector 1 is a standard D-subminiature 9-pin (DB-9
*
)
female connector, located on the bracket of the LVDS cable adapter board. It is
used to receive opto-isolated auxiliary input signals. It interfaces with the 50-pin
internal auxiliary I/O connector on the board, making the auxiliary signals
accessible outside the computer enclosure.
The pinout for this connector is as follows.The description of each auxiliary signal
states whether the signal is specific to an acquisition path and the type of signals
that can be routed onto it.
*. More accurately known as DE-9.

Description
1+,6- P2_OPTO_AUX(TRIG)_IN M_AUX_IO0 M_DEV2 Opto-isolated auxiliary signal (input) for acquisition path 2, which
supports: trigger input (trigger controller 1 on acq path 2) or user input.
4+,5- P1_OPTO_AUX(TRIG)_IN M_AUX_IO0 M_DEV1 Opto-isolated auxiliary signal (input) for acquisition path 1, which
supports: trigger input (trigger controller 1 on acq path 1) or user input.
7+,2- P0_OPTO_AUX(TRIG)_IN M_AUX_IO0 M_DEV0 Opto-isolated auxiliary signal (input) for acquisition path 0, which
supports: trigger input (trigger controller 1 on acq path 0) or user input.
8+,3- P3_OPTO_AUX(TRIG)_IN M_AUX_IO0 M_DEV3 Opto-isolated auxiliary signal (input) for acquisition path 3, which
supports: trigger input (trigger controller 1 on acq path 3) or user input.
9NC N/A N/A Not connected.
*. Note that only signals defined for acquisition path 0 (those that begin with P0) apply to the Matrox Solios eA/XA Single board. Only signals
defined for acquisition paths 0 and 1 (P0 or P1) apply to the Matrox Solios eA/XA Dual board.
†. These MIL constants represent the signals as of MIL 10. The signals that were previously represented by M_HARDWARE_PORTn became rep-
resented by M_AUX_IOn (where the value of n remained the same between the constants). For a complete list of changes between previous MIL
versions and MIL 10, see MilSoliosAnalogIOConversionTable within MIL Release Notes.
