AW00118303000 Acquisition Control
Basler racer GigE 99
Use Case 3 - Acquisition Start and Line Start Triggering Off (Free Run),
Frame Start Triggering On
Use case three is illustrated on page 100.
In this use case, the Acquisition Start Trigger Mode and the Line Start Trigger Mode parameters are
set to off. The camera will internally manage acquisition start and line start trigger signals without
any need for triggering by the user ("free run").
The Frame Start Trigger Mode parameter is set to on, requiring that a frame start trigger signal is
applied to the camera.
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. Note that the overall line rate will also
depend on the frame start trigger signal: Lines will only be acquired after a related preceding frame
start trigger signal has transitioned.
In this example, each frame is set to include three lines.
When the Acquisition Mode is set to Continuous Frame, the camera will be set to acquire frames
until an acquisition stop command is issued.
