CV-A1

6.3. Continuous Operation (Non triggered)

Trigger Mode Normal. TR=0. It is for applications where the camera is continuous running without external trigger. In normal mode the shutter mode can be normal or programmable exposure. (SM=0 SM=1). The shutter will work in all 16 steps up to 1/200,000 second or with the programmable exposure in 1023 steps. In partial scanning and binning modes, shutter times longer than the actual frame time has no meaning. The exposure will be equal the frame time. If external synchronizing is used input external HD and VD signals.

To use this mode:

 

 

Set function:

Trigger mode

TR=0

 

Shutter mode “Normal” or “Programmable”

SM=0, SM=1

 

“Shutter Speed”

SH=0 through 15

 

“Programmable exposure”

PE=1 through 1023

Input:

Ext. VD on pin 7 on 12-pin connector. If used.

 

 

Ext. HD on pin 6 on 12-pin connector. If used.

 

Important notes on using this mode

External sync system should follow the camera scanning and binning system.
