Internal Trigger. Scan mode | JAI CV-L105 instruction

CV-L105

6.2.1. Internal Trigger. Scan 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 exposure time is equal to the scanning time set by the SCAN 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). SHUTTER parameter has no function here.

To use this mode:
Set function:	Trigger	Internal
	Mode	SCAN
	SHUTTER value	No function
	SCAN value	151 µs through 32.5 ms
Input:	Clock, Binning and other functions
Input:

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.
