Note:
Although you must be operating the camera in exposure mode 2 to use the set
exposure time (
set
) command, the allowable exposure time increments listed above also
apply to exposure mode 4 (Smart EXSYNC) or 6 when exposure time overlaps frame
readout. This is because, in exposure mode 4, the falling edge is captured by the camera
every 18.513 µs for example in the case of
clm 15
or
16
,
sot 320
. In exposure modes
4 or 6 the exposure time effectively has an uncertainty of the allowable time increment.
Refer to section 3.4 Exposure Correction for more information on the
clm
and
sot
(sets
pixel rate) commands.
Refer to section Figure 10: Mode 2 on page 29 for an example where exposure time
overlaps frame readout.
3.4.4 Enabling EXSYNC Debounce Circuit
Purpose:
When enabled, the camera does not respond to any pulses on the
Exync input smaller than 1uS. The camera ships with this feature
disabled.
Syntax:
edc i
Syntax Elements:
i
EXSYNC
debounce.
0
= EXSYNC debounce disabled
1
= EXSYNC debounce enabled
Notes:
When disabled, the camera responds to the User EXSYNC input
the same as previous camera versions (00-R and non-RoHS).
Example:
edc 1
