5.1.1 Basic Info: Free Running
Free running with programmable exposure time. Frames are readout
permanently and valid data is indicated by LVAL per line and FVAL
by frame. There is no need to trigger the camera in order to get data.
Exposure time is programmable via serial interface and calculated by
the internal logic of the camera. The enclosed software allows the user
to set exposure time e.g. from 60 µsec 1Sec (camera type dependent).
Frame rate is configurable also (except SVS340xUCP). If the configu-
ration is saved to EEPROM the exposure time and frame rate set stay
resident after power off.
NOTICE
The fundamental signals are:
Line Valid: LVAL,
Frame Valid: FVAL,
and in case of
triggered modes: trigger input.
