AW00118302000 Acquisition Control

Basler racer GigE 105

Use Case 6 - Acquisition Start Triggering Off (Free Run), Frame Start and

Line Start Triggering On, Frame Start Trigger Level High,

Partial Closing Frame True

Use case six is illustrated on page 127.

This use case is equivalent to the preceding use case five, except for the fact that Partial Closing

Frame is set to True.

In this use case, the Acquisition Start Trigger Mode parameter is set to off. The camera will internally

manage acquisition start trigger signals without any need for triggering by the user ("free run").

The Frame Start Trigger Mode and the Line Start Trigger Mode parameters are set to on, requiring

that frame start and line start trigger signals are applied to the camera.

The Frame Start Trigger Activation is set to Level High. This means that a transition of the frame

start trigger signal is always present as long as the signal stays high. Accordingly, during this period

frames can be acquired without interruption which otherwise will happen if a related preceding

transition of the frame start trigger signal has not occurred (c.f. also use case four).

In this example, each frame is set to include three lines.

In this example, the frame start trigger signal goes low while a frame is being acquired (i.e. while

line one of the closing frame of the sequence of frames is being acquired). With Partial Closing

Frame set to true, only the partial closing frame will be acquired and transmitted. In this example,

the partial closing frame includes only one line.

When the Acquisition Mode set to Continuous Frame, the camera will be set to acquire frames until

an acquisition stop command is issued.
