6.4.1. Continuous Operation (Non triggered)
Mode settings can be done with RS-232C. Trigger Mode Normal. TR=0. It is for applications where
the camera is continuously running without external trigger. The shutter mode can be normal or
programmable exposure. (SM=0, SM=1). The shutter will work in all 10 steps up to 1/14,000
second or with the programmable exposure in 1216 steps. In partial scanning, shutter times
longer than the actual frame time has no meaning. The exposure will be equal the frame time.
In this mode it is possible to have CCIR/EIA composite analogue video output for monitor use. It
is for full scan only. The video can be 50 or 60 frames per second with a line frequency at 15.734
kHz. CCIR has 290 active lines. Shutter speed <313 LVAL. EIA has 240 active lines. Shutter speed
<263 LVAL.
To use this mode:
Set function:
Trigger mode “Normal” TR=0
Shutter mode “Normal” or “Programmable” SM=0, SM=1
“Shutter Speed” SH=0 through 9
“Programmable exposure” PE=1 through 1216
Scanning format SC=0 through SC=4
Output select OS=0, OS=1, OS=2
Polarity and other functions
Important notes on using this mode.
• Analogue video output OS=2 only for full SC=0

For horizontal timing refer to 6.2.3 through 6.2.6. (Fig.17. through fig. 20.)
