6.2.2. Internal Trigger. Shutter mode.

In this mode, the camera does not require an EXT TRIG signal to be issued to the camera. The line rate (scan rate) is generated inside the camera. The camera will operate continuously with its internal trigger.

The scanning interval is equal to the time set by the SCAN parameter.

The exposure time is equal to the Shutter time set by the SHUTTER parameter via RS-232C. The permitted range for the scan rate is 151 µs to 32.5 ms (corresponds to 6.6 kHz to 30 Hz). The permitted range for the exposure time, SHUT value, is 1 µs up to (SCAN time – 150 µs). (Always less than SCAN.)

To use this mode:

SHUTTER value

1 µs up to 32.35 ms

 

SCAN value

151 µs through 32.5 ms

 

Clock, Binning and other functions

 

Input:

Ext. trigger through the LVDS connector

 

Important notes on using this mode:-

It is only recommended to use this mode when there is not change of speed in the object being scanned. If the speed of the object changes, the aspect ratio in the vertical (scanning) direction will change.
