6.8 Trigger IN
General
Trigger IN is used to tag images on the camera side so they are recorded on the software.
The status of the trigger IN signal at start of integration is added on the frame header sent to
the recording software.
∆
T is a jitter of one frame period maximum. The Trigger IN signal must be at least one frame
period long. All frames are sent to the PC. ResearchIR Max will start or stop acquisition
based upon Trigger IN signal. This is configured in the start and stop conditions of the
ResearchIR Max recording tab of the left panel.
When to use this configuration?
-
To capture a fugitive event. The camera will acquire images, but the software only records
the frame of interest.
-
When a precise start of recording time is requested.
-
When only few frames are needed to be recorded
When NOT to use this configuration?
-
When it is needed to trigger each acquisition. In that situation, it is preferable to use the Sync
IN input.
