Command SM : Shutter mode
SM=0 Preset shutter SM=1 Programmable exposure
Command SM=0 Preset shutter
0=OFF(1/60) 1=1/120 2=1/250 3 =1/500 4=1/1000 5=1/2000
6=1/5000 7=1/ 10,000 8=1/20,000
Command SM=1 Programmable exposure
The exposure time can be set in 1 LVAL unit in the range from 2LVAL to
1,125 LVAL.
Maximum shutter time Command: PE=1125
14.815
μｓ
x 1125 LVAL = 16.67ms
Minimum shutter time Command: PE=2
14.815us * 2 LVAL = 29.63 µs
LVAL period = 14.815 µs.
Important Note:
•
The electronic shutter is available together with Window scan, but it is effective only when
the preset shutter value (LVAL) is set at a value less than the Window height. If the shutter
value is larger than the window height (lines), the shutter is automatically set to OFF.
•
When the Strobe-Preset Snapshot trigger mode is selected the shutter is automatically set
to OFF.
