Trigger Function; Syncout - Fluke tix640 User Manual

Trigger Function

Triggering uses the Ethernet to affect the 16-bit data
transmission. The TTL/CMOS signal is forwarded to the
thermal imager (right-hand side socket) using the BNC
sockets marked T1 and T2 of the breakout box and from
there using the connecting cable with 14-pin LEMO
connector.
In order to connect the trigger signal sources to the
breakout box, commercially available BNC cables may be
used:
T1 Trigger channel 1 is used by the software.
•
T2 Trigger channel 2 is reserved for the SDK and
•
further specific applications.
The voltage level of the trigger signals from the
thermal imager to the input and the output is 5 V
TTL/CMOS.
The thermal imager reacts to a low-high trigger edge. The
trigger event causes simultaneous marking in the heater
of the following frame (IR image). Within the software, this
mark is analyzed 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.
Note

SyncOut

The frame rate of the thermal imager cannot be controlled
from the outside. In order to synchronize other cameras
and processes, and for active thermography applications,
the Framesync signal of the thermal imager 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 synchronization pulse has a
length of approx. 600 µs.
The trigger channels are configured using the application
software online.
