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.) (>72.64sec 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).
