As shown in Figure 8-18, the camera with trigger mode OFF begins after receiving an AcquisitionStart
command.
At point 1, the camera gets a command of setting trigger mode ON while it is in wait state. The trigger
mode is not active until the 3
rd
frame is finished (including exposure and reading out), i.e., point 2. Please
note that the 3
rd
frame does not belong to trigger mode. All trigger frames need trigger signals or soft-
trigger commands. At point 3, the camera gets a command of switching back to continuous mode. It is
also not active until the 5
th
frame is finished, it should wait a complete frame. The camera switches from
trigger mode to continuous mode at point 4, and then the camera works in continuous mode.

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 10Gigabit 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
