Matrox Solios GigE acquisition section 95
You can specify the required on/off state for an user-defined output signal and
have the auxiliary I/O controller generate and route it to an auxiliary output signal
(or auxiliary I/O signals in output mode) configured as a user-defined signal; your
application can set the on/off state of the signal based on some analysis.
To inquire and control user-defined signals, use the MIL-Lite functions
MdigInquire() and MdigControl() with M_USER_BIT_...
Combining signals
Matrox Solios GigE allows you to combine different signals and output them on
one auxiliary signal, using an AND or OR operation. You can combine:
• Two exposure signals. This allows you to generate, for example, multiple pulses
or more complex pulses on one signal. The two exposure signals must be generated
from the same group of exposure timers (either exposure timers from group 1 to 4
or from group 5 to 8).
• An exposure signal with a user-defined output signal. This allows you to output,
for example, an exposure signal for a video source that must capture an object only
if an image of the object at a different angle met some analysis threshold.
• An exposure signal with a timer-trigger input signal. This allows you to output,
for example, an exposure signal for a line-scan video source capturing a variable
length object (in this case, a frame valid signal would be used as the trigger).
To combine different signals, use the MIL-Lite function MdigControl() with
M_AUX_SIGNAL_SOURCE and M_AUX_SIGNAL_COMBINE.
