first frame can be programmed. For IPX-VGA - from 500 usec to 32 msec
(in 500 microseconds increments). For IPX-1M48, IPX-2M30 and IPX-
2M30H - from 1 msec to 64 msec (in 1.0 msec increments). For IPX-4M15 -

number of frames captured after the trigger pulse goes high can be

command. Along with the shutter pulse,
(200 microseconds duration) for synchronization with an external strobe.
This pulse is always present in the external trigger mode.
CAUTION NOTE
1.
Enabling several trigger options at the same time will result in

For proper operation - if series of trigger pulses are used, make
tion – refer to section 2.1.4 Timing
from 2 msec to 128 msec (in 2 msec increments). For IPX-11M5 - from 5
msec to 320 msec (in 5 msec increments). There is a fixed additional delay
of 10 usec (because of the shutter pulse) between the rising edge of the
trigger pulse and the beginning of the integration – Figure 2.32. If the CC1
input is used - the duration of the CC1 trigger pulse is used to determine the
first frame exposure time. After the first frame has been exposed, the camera
is free running
from 1 to 250 frames, or to be free-runni
the camera sends one strobe pulse
