Strobe Output
The Strobe output is used to activate a photo strobe at the time of image acquisition on
the currently selected camera. The strobe device to be triggered should have optically
isolated inputs.
For the original MVS-8100 and MVS-8100M (styles A and B), the strobe output signal is
a pulse of 20 to 30 mA, with a duration of about two horizontal line scans. The active
sense (or polarity) of this output is high.
For the MVS-8100M+, the strobe pulse width and duration is settable with software
commands.
