TRIGIN = enables the image processor.
TRIGOUT = from the image processor stays active, enabling exposure, for
640 msec after the xray switch is released. This ensures sufficient time to for last
image hold. The timer U14 on the B100 board terminates exposure after 2 seconds
if the TRIGOUT does not terminate after the 640 msec time period.
