7.9 Trigger Functionality VarioCAM
Triggering only affects the 16-bit data transmission via FireWire. A 14-core system cable transmits the
TTL/CMOS-signal from the interfaces "T1" and "T2" on the Breakout Box to the VarioCAM
included trigger cables in order to connect the Breakout Box, see Fig. 24 and Fig. 27.
■ T1 Trigger channel 1 is used by software IRBIS
■ T2 Trigger channel 2 is reserved for SDK and further specific applications.
The voltage level of the VarioCAM
®
The VarioCAM hr reacts to low-high trigger edges. The trigger event effects a tagging of the FireWire
header index of the next frame (IR image). This tag will be evaluated by the IRBIS
IRBGRAB.DLL, which will then save the respective data. The minimum length of the trigger signal is 10
ns. However, the impulse should not be shorter than approximately 3 ms in order to make for a precise
assignment to the current frame. Nevertheless, a cadence with a duty cycle of 1:1 is also possible.
