AW00118302000 Acquisition Control

Basler racer GigE 107

Use Case 7 - Acquisition Start and Frame Start Triggering Off (Free Run),

Line Start Triggering On

Use case seven is illustrated on page 129.

This use case is equivalent to use case two, except for the fact that the Line Start Trigger Mode

parameter is set to on.

In this use case, the Acquisition Start Trigger Mode and the Frame Start Trigger Mode parameters

are set to off. The camera will internally manage acquisition start and frame start trigger signals

without any need for triggering by the user ("free run").

The Line Start Trigger Mode parameter is set to on, requiring that a line start trigger signal is applied

to the camera.

The rate at which the camera will acquire lines will be determined by the line start trigger signal and

must be below the maximum allowed line rate determined by the current setting.

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.

If an Acquisition Stop command is issued when not all lines of the current frame are yet acquired,

the partial frame will be transmitted. Here, two situations can be distinguished:

 if the Acquisition Stop command is issued during exposure of the second line acquisition, the

second line will be dropped and the partial frame will only include its first line.

 if the Acquisition Stop command is issued during readout of the second line acquisition, the

readout will be completed and the partial frame will include the related lines one and two.
