6.2.4 Shutter-Select mode with external trigger
This mode allows the user to have full control of the exposure time, by programming a timing
generator, while the line rate is controlled by an external trigger signal. The camera can accept an
external trigger through the Camera Link connector or though the 12-pin Hirose connector.
To use this mode:
Set function
Trigger
TR=1
Trigger origin, external
TG=1
Individual R, G and B exposure
EI=0(individual)
EI=1(tracking with G)
Programmable exposure
PER/PEG/PEB/PEIR=80 to 2150400 CLK
Trigger period
53.8
μs
Important note:
•
If using individual exposure, the EEN signal represents the channel with the longest exposure time
•
The trigger interval is more than 53.75
μs.
•
If one-push auto white balance is used, using the shutter (command AH) or using the gain
(Command AW) depends on applications. If the auto white balance switch located on the rear
panel is used, only the gain is effective.
•
When the one-push white balance has been initiated and the rear panel LED shows orange, the
camera must receive continuous external trigger pulses corresponding to the frequency and duty
cycle used in the application.
•
The maximum trigger period is the interval of the input trigger.
