6.6.2.
No-Shutter mode with External Trigger
In this mode, the exposure time is directly proportional to the line rate. The line rate is
generated externally by a trigger signal. This mode is used when an external trigger signal
is
available, e.g. from an encoder, and the scan rate can be controlled by this signal. The camera
can accept an external trigger through the Camera Link connector or though the 12-pin connector.
To use this mode:
Set function
Trigger mode, No-Shutter
TR=0
Trigger origin, external
TG=1
Trigger input
TI=0 or 1
Important note:
•
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.

Shutter-Select mode with Internal line rate generator
This mode allows the user to have full control of the line rate and the exposure time individually, by
programming separate timing generators. Subsequently the camera does not accept an external
trigger signal in this mode.
To use this mode:
Set function
Trigger mode, Shutter-Select
TR=1
