Delay of V Sync Signal
(In slave boards, the Vsync signal is a
“through-out” output.)
Delay of TTL Trigger Signal
These delays may cause an offset of one frame between cameras in multiple-camera operation
depending on a certain timing of trigger entry.
2.3.4 Recording Interval in Random Center and
Random Manual Trigger Modes
In Random Center and Random Manual modes, because Center or Manual operation is
repeatedly executed, the following interval is necessary between one recording and next. The
interval can be checked by observing Rec Pos/Neg signal on GENERAL OUT.
Note: The necessary interval depends on the PC being used. More interval may be needed
depending on the nature of the PC. The above interval is needed when using a PC with
Pentium 4 (2.4GHz).
