6.5. Edge Pre-select Mode

The leading edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by the pre-defined shutter speed set by RS-232C.

The resulting video is output as “odd field” for EIA and “even field” for CCIR, and appear 9H (EIA9 or 10H (CCIR) after the leading edge of WEN (polarity is user selectable).

To use this mode:

 

 

Set function:

Trigger mode to “Edge Pre-select”

TR=1

 

Accumulation to “Field”

FR=0

 

Scanning to “Non-interlaced”

SC=1

 

Shutter mode to “Normal” or “Programmable”

SM=0, SM=1

 

Shutter Speed

SH=0 through 7

 

or Programmable exposure

PE=1 through 1023

 

Polarity for trigger and other functions

 

Input:

Ext. trigger to pin 5 on 6 pin connector (or pin 11 on 12-pin connector).

 

Ext. HD to pin 6 on12-pin connector. (If used).

Important notes on using this mode:-

•The duration of the external trigger pulse must be greater than 1H. It is recommended to make this longer, typically 9H.

•Do not input external VD signal at Pin No. 7 of the 12-pin Hirose connector, as it may disturb the external trigger function.
