64 Appendix B: Technical information
The auxiliary signals are path independent; regardless of the acquisition path that
is being used to grab images, any of the auxiliary signals can be used. For more
information, see the Auxiliary signals section in Chapter 4: Matrox Rapixo CXP
hardware reference chapter for supported functionality.
The pinout for auxiliary I/O connector 0 is as follows. Auxiliary I/O connectors
1, 2, and 3 have the same pinout as auxiliary I/O connector 0, except you must
add 8, 16, or 24, respectively, to the number at the end of their hardware signal
name and MIL constant. For example, AUX(TRIG)_TTL_IO_4 on connector 0
would be AUX(TRIG)_TTL_IO_12 on connector 1.
