Sigma LBA-400 Manuel D’Utilisation

If your camera is a low power CCD style that runs on +12Vdc, then it may be powered from 
connector J1 (J3 on LBA-3/4/500 frame grabbers) pin 6 (+12Vdc) and pin 5 (gnd).   

 

The electronic shutter control signals are provided on as SHUT1, SHUT2, and SHUT3.  These are TTL 

level drive outputs.  The Logic is positive true.  The shutter settings are listed in the 8 lines of the 

Shutter drop down edit control found in the main menu Options > Camera > Advanced dialog 

box.  The labeling of the shutter lines can be user modified to match the settings of a particular 

camera.  The line locations however, always correspond to the following TTL output drive levels:
