1.Description
The TrigBox 3.0 is the perfect device to synchronize a video camera with a flashlight lighting
(stroboscope). TrigBox 3.0 is working with every standard analog camera systems. A possible
application is realized in the synchronisation with the Laserflash.
2.Application
If one has to light up an observed scene with a flashlight, it is necessary to synchronize the image
frequency of the video camera with the flash frequency of the light source. A unsynchronized
setup leads to flares in the stored movie.
In particular, if the lightning duration is shorter than the exposure duration of the camera, a careful
coordination of lightning time and exposure time of the video camera is very important.
3.Operational principle:
TrigBox 3.0 uses the analog standard video signal (Fbas, Standard: CCIR, RS179 o.ae.), in order
to produce 12V-driving signal (5V TTL optionally). This releases a flash during the lightning
operation. The driving pulse can be coordinated with the exposure window of the CCD camera by
an internal delay generator .In particular this is necessary at short exposure times of the camera
(1/1000 second).
.Conditions of work:
The standard version of the TrigBox 3.0 is conceived for inside application. On request also
equipment for outside applications can be offered.
5.Display announcement
In the display a number between 00 and 99 is indicated. This number is proportionally to the pulse
length wich is given to the Laserflash. 100µs to 5ms.
The day-night-sensor can switched on and of with the P key.
The display switches off after approx. 10 seconds automatically. It can be activated by pressing
one of the buttons.
After 10s the actual value for the pulse length is stored into the system memory.

6.Day-night-sensor
The integrated daylight sensor allows the deactivation of the TrigBox at a defined daylight level. In
the battery operation this leads a longer battery live. To adjust the daylight level press:“P and +“ or
„P and -“ . A zero indicates that the TrigBox is always on (sensor is disabled).
1-9 defines the Switch off level.

7.Controlling the TrigBox via RS232 (Com Port)
Each command line has to end with one of the followíng commands:
<CR> (Carriage Return, ASCII Code 13), <LF> (Line Feed, ASCII Code 10) or „#“If the command
is correct the interpreter send a „OK“-string, if the command is unknown the answer is „?“.
example:D=4000 OK
