■ T1 Trigger channel 1 is used by the IRBIS
®
3 software.
■ T2 Trigger channel 2 is reserved for the SDK and further specific applications.
The voltage level of the trigger signals from the VarioCAM
®
HD to the input and the output is 5V TTL/CMOS.
The VarioCAM
®
HD reacts to a low-high trigger edge. The trigger event causes simultaneous marking in
the heater of the following frame (IR image). Within the IRBIS
®
3 software, this mark is analysed by the
IRBGRAB.DLL implemented there and results in the corresponding data being saved. The minimum
width of a trigger pulse should be 10 µs in order to allow an unambiguous assignment to the current
frame.
Depending on the event, signals can be generated via T1 and T2 using the alarm functionality. The
appropriate setting for this is described in section 9.4.6 Menu item "Alarm", page 73.
7.9.2 SyncOut
The frame rate of the VarioCAM
®
HD cannot be controlled from the outside. In order to synchronise other
cameras and processes, and for active thermography applications. the Framesync signal of the
VarioCAM
®
HD can be generated, however, The generation of the Framesync signal is activated by the
corresponding software command, In the event of a low-high edge, the Framesync signal starts
simultaneously with the recording of the first image line. The synchronisation pulse has a length of
approx. 600 µs.
The trigger channels are configured using the application software IRBIS
®
3 online.
