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 

 

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).
