LT-200CL306.4.4 Shutter-select mode with external triggerThis mode allows the user to have full control of the exposure time, by programming a timinggenerator, while the line rate is controlled by an external trigger signal. The camera canaccept an external trigger through the Camera Link connector or though the 12-pin Hiroseconnector.To use this mode:Set function Trigger TR=1Trigger origin, external TG=1Individual R, G and B exposure EI=0(individual)EI=1(tracking with G)Programmable exposure PER/PEG/PEB=2064 to 1056720(25.8μs to 13.209ms in 12.5ns steps)Important note: If using individual exposure, the EEN signal represents the channel with the longest exposuretime The minimum trigger intervalScan mode Trigger input via Minimum interval (μs)Full/Binning Camera link 33.4125Hirose 12-pin 37.9125Sub-sampling/windowing Camera link 20.6125Hirose 12-pin 25.1125 The minimum trigger pulse widthTrigger input via Minimum trigger pulse widthCamera link 500 nsHirose 12-pin 5μs The maximum exposure time is the line rate. When the one-push white balance has been initiated and the rear panel LED shows orange,the camera must receive continuous external trigger pulses corresponding to the frequencyand duty cycle used in the application.Fig. 43 Shutter-select mode with external trigger (and individual exposure)Note: The largest exposure time is output as EEN.
