8.5.3 Pulse Width Control Trigger Mode
In this mode the accumulation time is equal the trigger pulse width. Here it is possible to
have a long time exposure. The maximum recommended time is <240 frames ( 2 seconds).
For timing details, refer to fig. 17 through fig. 22 and fig. 25 & 26.
To use this mode:
Set function:
Trigger mode
Pulse width control
Scanning
Full, Partial
Vertical binning
ON / OFF
Input:
Ext. trigger.
HIROSE 12-pin GPIO
Important notes on using this mode
1.
The minimum trigger interval > 2 LVAL
2.
Depending on the timing of the leading edge of the trigger pulse in relationship to
FVAL, accumulation will be synchronous or asynchronous in relationship to LVAL. See
8.3.4 Auto-detect LVAL-sync / async accumulation
3. The minimum trigger interval is as follows.
Scan mode

Note: In order to keep the minimum trigger interval in the partial scan mode, the
exposure time should not exceed the line number at normal scan. If the exposure time
is set longer than that, the trigger interval is longer by (Exposure time – normal scan
line number). The maximum exposure time is 511L.
