AW00118303000 Acquisition Control
Basler racer GigE 97
Use Case 2 - Acquisition Start, Frame Start, and Line Start Triggering Off
(Free Run), Continuous Frame Mode
Use case two is illustrated on page 98.
This use case is equivalent to the preceding use case one, except for the fact that the acquisition
mode is set to Continuous Frame.
In this use case, the Acquisition Start Trigger Mode, the Frame Start Trigger Mode, and the Line
Start Trigger Mode parameters are all set to off. The camera will internally manage acquisition start,
frame start, and line start trigger signals. When the camera is set this way, it will constantly acquire
lines without any need for triggering by the user. This use case is commonly referred to as "free run".
The rate at which the camera will acquire lines will normally be determined by the camera’s
Acquisition Line Rate Abs parameter. If the Acquisition Line Rate Abs parameter is disabled, the
camera will acquire lines at the maximum allowed line rate.
In this example, each frame is set to include three lines.
When the Acquisition Mode is set to Continuous Frame, the camera will acquire frames until an
acquisition stop command is issued.
If an acquisition stop command is issued when not all lines of the current frame are yet acquired,
the partial frame will be transmitted.
