CV-A10 CL and CV-A70 CL
6.4.6. Reset Continuous Trigger mode
The RCT mode is in principle the same as normal continuous mode. The difference is that an
external trigger pulse will immediately stop the video read out and reset and restart the vertical
timing. After a fast dump read out, which takes 86 LVAL, a new triggered exposure is started
and read out as normal. If no further trigger pulses are applied, the camera will continue in
normal mode. This fast dump read out has the same effect as “smearless read out”. Smear over
highlighted areas are reduced for the triggered frame.
The restart continuous trigger mode makes it possible to use a lens with video controlled iris in
intelligent traffic surveillance applications.
For timing details, refer to fig. 13. through fig. 17. and fig. 30.
To use this mode:
Set function: Trigger mode to “Reset continuous trigger”. TR=10
Scanning SC=0 through 3
Vertical binning. (CV-A10 CL only) VB=0 through 3
Horizontal binning. (CV-A10 CL only) HB=0 through 3
Shutter mode normal, programmable or auto SM=0 through 2
Shutter speed SH=0 through14
Programmable exp. PE=0 through 625
Accumulation LVAL synch. or a-synch. LS=0, LS=1
Other functions and settings
Input: Ext. trigger. Camera Link or 12 HiRose TI=0, TI=1
Ext. HD in on pin 6 on 12-pin connector. (If used).
Important notes on using this mode
External sync system should follow the camera scanning system.
To avoid ≤ 1 LVAL jitter if LS=1, ext. HD/Trigger phase relations as shown in fig. 23.
Trigger pulse width >2 LVAL to < 1 frame.
If LS=0, the minimum trigger interval >(1 FVAL + 3 LVAL).
If LS=1, the minimum trigger interval >(trigger width + 1 FVAL + 2 LVAL).
