6.7. Frame-delay read out Mode
In this mode the pre selected exposure starts from the leading edge of the trigger pulse, H
synchronous or H a-synchronous. It can be the 10 steps in normal or 1056 steps in programmable.
SM=0 or SM=1. The resulting video is read out at the trailing edge of the trigger.
This mode will operate with full and partial scanning and with V binning (M4
+ and M4 + CL only).
Partial scanning and binning in combinations is not allowed.
If smearless read out (SL=1) is used, the exposure starts with a delay 133H (5.23 msec.) after the
trigger. An EEN pulse will indicate the active accumulation time, and a FEN pulse indicates that
the resulting video is read out.
To use this mode:
Set function:
Trigger mode “Frame delay read out” TR = 3
“H synchronous accumulation” HC=0, HC=1
“Smearless readout” SL=0, SL=1
Polarity and other functions
Input: Ext. trigger to LVDS/Camera Link or pin 10 on 12-pin connector.
Important notes on using this mode.
• The duration of the trigger should be longer than the exposure time + (>2H to <3V.)
(>72.64µsec to <120msec).
• The minimum trigger interval should be >(trigger pulse width + 1 frame). A new trigger
must not be applied during the previous frame read out. (Before FEN is high).
