The trigger signal's pulse width must be greater than one pixel. The pulse width
is determined by the following:
Minimum pulse width
For example, if the pixel frequency is 24.54 MHz, the minimum pulse width is
1/24.54 MHz x 2 ≈ 82 nsec. Therefore, the minimum pulse width must be greater
than 82 nsec.
Trigger events are controlled using the MdigControl() function in MIL/MIL-Lite.
User bits
Both Matrox Orion /Standard and /Dual for 4Sight-II support four LVTTL
(3.3 V) user bits through the video input connector: two input and two output.
These are available for controlling external events such as a strobe light. Note that
these user bits are not available through the second video connector ("Video in
2") on Matrox Orion /Dual for 4Sight-II.
User bits are programmed using the MIL/MIL-Lite function MdigControl().
