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 Hirose connector.
To use this mode:
Set function Trigger mode, No-shutter TR=0
Trigger origin, external
Trigger input
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.
