AW00118302000 Acquisition Control
Basler racer GigE 109
Use Case 8 - Acquisition Start Triggering On, Frame Start and
Line Start Triggering Off (Free Run)
Use case eight is illustrated on page 131.
In this use case, the Acquisition Start Trigger Mode parameter is set to on, requiring that an
acquisition start trigger signal is applied to the camera.
The Frame Start Trigger Mode and the Line Start Trigger Mode parameters are set to off. The
camera will internally manage frame start and line start trigger signals without any need for
triggering by the user ("free run").
In this example, Acquisition Frame Count is set to two. Accordingly, two consecutive frames will be
acquired for each transition of the acquisition start trigger signal.
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 acquisition start trigger signal: Lines will only be acquired after a related preceding
transition of the acquisition start trigger signal has occurred.
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.
