8.2.5. Continuous Mode and Configuration
Continuous mode configuration
The default value of
Trigger Mode
is
OFF
in default user set. If the camera is opened with default user
set, the camera works in continuous mode directly. Otherwise, user can set
Trigger Mode OFF
to use
continuous mode.
Other parameters also can be changed in
Trigger Mode OFF
.
Continuous mode features
In continuous acquisition mode, the camera acquires and transfers images according to camera parameter
set.
In continuous mode, ROI size, packet delay may have effects on frame rate.
8.2.6. Software Trigger Acquisition and Configuration
Software trigger acquisition configuration
The camera supports software trigger acquisition mode. Three steps followed should be ensured.
1) Set the Trigger Mode to ON.
2) Set the Trigger Source to Software.
3) Send Software Trigger command.
All the software trigger commands are sent by the host through the Gigabit Ethernet bus, to trigger the
camera to capture and transmission images.
Software trigger acquisition features
In software trigger acquisition mode, the camera begins to acquire one image after receiving software
trigger commands. In general, the number of frames is equal to the number of software trigger commands.
The relative features are illustrated below:
1) In software trigger acquisition mode, if the trigger frequency is lower than permissible maximal FPS
(Frame per Second) of the camera, the current frame rate is trigger frequency. If the trigger frequency
is higher than permissible maximal FPS (Frame per Second) of the camera, some software triggers
are ignored and the current frame rate is lower than trigger frequency.
2) The trigger delay feature can control the camera delay interval between your triggers and the camera
acquiring frames. The default value of trigger delay time is zero.
