Auxiliary signals
This section describes the auxiliary signals available on Matrox Rapixo CXP.
Auxiliary signals available on Matrox Rapixo CXP
The auxiliary signals of Matrox Rapixo CXP are acquisition path independent and
can be used to initiate on-board events (inputs) or can be transmitted to third-party
devices (outputs). You can also reroute an auxiliary input signal to a video source
via the CoaXPress trigger output signal.
The following table summarizes the auxiliary functionality that Matrox Rapixo
CXP supports using its auxiliary I/O signals. The table also documents the MIL
constants to use.

*. MIL constant, where n corresponds to the number in the row.
†. There is no limit to the number of events that can be triggered simultaneously using the auxiliary input signals, nor is there a restriction on
which auxiliary signal can be used to trigger an event.
‡. A rotary encoder with quadrature output transmits a two-bit code. The table entries 0 and 1, therefore, denote bit position.
