Lookup tables

Matrox Radient eV-CXP has on-board lookup tables (LUTs) that can be used to
precondition input data at acquisition time, before it is stored in memory.
There is one LUT palette available per CoaXPress acquisition path for 8- and
10-bit data. For 12-bit data, all acquisition paths use the same palette. For 14- and
16-bit data, a transparent LUT palette is used. The LUTs are programmed using
the MIL-Lite function MdigLut().
CoaXPress trigger and GPIO signals
To communicate exclusively with the video source(s), Matrox Radient eV-CXP
supports CoaXPress trigger signals, CoaXPress GPIO signals, and control
messages. Control messages are basic communication messages that facilitate data
transmission between the video sources and the board.
For each video source connected to the board, Matrox Radient eV-CXP provides
a trigger signal and 4 GPIO signals. These signals can be configured as input
signals, sent from the video source to the board, or output signals, sent from the
board to the video source. These signals can be programmed using the MIL-Lite
function MdigControl() with M_USER_BIT...
Matrox Radient eV-CXP can send CoaXPress trigger and GPIO signals to a video
source to initiate image acquisition. The video source can send CoaXPress trigger
and GPIO signals to the board, for example, to arm a trigger, to start a timer, or
to trigger other off-board devices (via the auxiliary output signals). For more
information on how to use the auxiliary input and output signals, refer to the
following Auxiliary signals section.

Auxiliary signals

The auxiliary signals of Matrox Radient eV-CXP can be used to initiate on-board
events (inputs), can be transmitted to third-party devices (outputs), or can be
rerouted to or from the CoaXPress trigger and GPIO signals.
You can use any of the auxiliary input signals of Matrox Radient eV-CXP as a
trigger acquisition signal, or to arm a trigger or start an exposure timer. An auxiliary
input signal can also be rerouted to a video source as a CoaXPress trigger or GPIO
signal; it can be used as a camera exposure signal, or as an image acquisition trigger.
