6.6 The “I/O Signals” tab
Exposure Trigger
If checked, a signal for [External Exp. Start] or [External Exp.
Ctrl] trigger mode (see chapter 6.2) is accepted at the exp trig
input.
Acquire Enable
If checked, a signal for Acquire Mode (see chapter 6.5) is
accepted at the acq enbl input.
Status Busy
If checked, a signal indicating busy status is given at the status
busy output. Once an acceptable trigger edge is received, busy
will go high. As soon as busy goes low again, a new trigger
edge is accepted.
Status Expos
If checked, a signal indicating exposure status is given at the
status output. Status Expos indicates the actual exposure
window for one frame.
Status Line
If checked, a signal indicating line status is given at the status
output. Use the falling line edge for optimized synchronization
(minimized jitter time; see page 18).
