9.6.1 Acquisition Start Trigger Mode (Legacy Mode)
The main parameter associated with the acquisition start trigger is the Trigger Mode parameter. The
Trigger Mode parameter for the acquisition start trigger has two available settings: off and on.
9.6.1.1 Acquisition Start Trigger Mode = Off
When the Acquisition Start Trigger Mode parameter is set to off, the camera will generate all
required acquisition start trigger signals internally, and you do not need to apply acquisition start
trigger signals to the camera.
With the trigger mode set to off, the way that the camera will operate the acquisition start trigger
depends on the setting of the camera’s Acquisition Mode parameter:
If the Acquisition Mode parameter is set to single frame, the camera will automatically generate
a single acquisition start trigger signal whenever it receives an Acquisition Start command.
If the Acquisition Mode parameter is set to continuous frame, the camera will automatically
begin generating acquisition start trigger signals when it receives an Acquisition Start
command. The camera will continue to generate acquisition start trigger signals until it
receives an Acquisition Stop command.
The rate at which the acquisition start trigger signals are generated will be determined by the
camera’s Acquisition Frame Rate Abs parameter:
If the parameter is not enabled, the camera will generate acquisition start trigger signals
at the maximum rate allowed with the current camera settings.
If the parameter is enabled and is set to a value less than the maximum allowed frame
rate with the current camera settings, the camera will generate acquisition start trigger
signals at the rate specified by the parameter setting.
If the parameter is enabled and is set to a value greater than the maximum allowed frame
rate with the current camera settings, the camera will generate acquisition start trigger
signals at the maximum allowed frame rate.
For information about setting the Acquistion Frame Rate Abs parameter, see Section 9.6.1.3 on
page 132.
Exposure Time Control with the Acquisition Start Trigger Mode Off
When the Trigger Mode parameter for the acquisition start trigger is set to off, the exposure time for
each frame acquisition is determined by the camera’s exposure time parameters.
For more information about the camera’s exposure time parameters, see Section 9.7 on page 141.
Keep in mind that the camera will only react to acquisition start triggers when it is
in a "waiting for acquisition start trigger" acquisition status. For more information
about the acquisition status, see Section 9.2 on page 105 and Section 9.4 on
page 111.
