4.3.2 Electrical
specifications ST6 camera interface
Trigger IO Specifications:
The board features two fast CMOS trigger inputs (for use as image capture trigger) and two
corresponding CMOS trigger outputs (as strobe-light trigger). Since the signals are fast at a very low
noise margin, it is recommended to keep the cable as short as possible. Use twisted pair or even
coaxial cable for this purpose. The trigger input assures a constant image capture delay without jitter.
The SBC64XX features at the time only synchronized triggering (both images triggered
simultaneously). Trigin A and trigin B must be triggered together (
pins 2 and 4 have to be
connected
), otherwise triggering will not work!!
!
This limitation will be removed with a software update (future version of VCRT).
