8.3 Acquisition Monitoring Tools

The camera includes the acquisition status feature and generates four output signals that you can

use to monitor the progress of line and frame acquisition by the camera: the exposure active signal,

the acquisition trigger wait signal, the frame trigger wait signal, and the line trigger wait signal.

These signals are designed to be used when you are triggering acquisition start, frame start or line

start via a hardware trigger signal.

The camera will ignore a hardware trigger signal when it is not waiting for it:

 If a camera receives a hardware acquisition start trigger signal when it is not in a "waiting for

acquisition start trigger" acquisition status, it will simply ignore the trigger signal and will

generate an acquisition start overtrigger event.

 If a camera receives a hardware frame start trigger signal when it is not in a "waiting for frame

start trigger" acquisition status, it will simply ignore the trigger signal and will generate a frame

start overtrigger event.

 If a camera receives a hardware line start trigger signal when it is not in a "waiting for line start

trigger" acquisition status, it will simply ignore the trigger signal and will generate a line start

overtrigger event.

The camera’s trigger wait signals give you the ability to check whether the camera is waiting for the

related hardware trigger signal:

 The acquisition trigger wait signal gives you the ability to check whether the camera is in a

"waiting for acquisition start trigger" acquisition status. If you check the acquisition trigger wait

signal before you apply each hardware acquisition start trigger signal, you can therefore avoid

applying acquisition start trigger signals to the camera that will be ignored.

 The frame trigger wait signal gives you the ability to check whether the camera is in a "waiting

for frame start trigger" acquisition status. If you check the frame trigger wait signal before you

apply each hardware frame start trigger signal, you can avoid applying frame start trigger

signals to the camera that will be ignored.

 The line trigger wait signal gives you the ability to check whether the camera is in a "waiting for

line start trigger" acquisition status. If you check the line trigger wait signal before you apply

each hardware line start trigger signal, you can avoid applying line start trigger signals to the

camera that will be ignored.

For more information about the trigger wait signals, see Section 8.3.3 on page 125.
