CV-M77 5.4 Input and Output Circuits In the following schematic diagrams the input and output circuits for video and timing signals are shown. For alternative connections refer to “Internal Switch and Jumper Settings”. Jumper settings are shown as for factory default. 5.4.1 Video input The video out...

CV-M77 6 Functions and Operation Apart from the standard continuous operation, the CV-M77 features three external triggering modes, Edge Pre-select, Pulse Width Control mode and Readout Delay mode. These 3 external triggering modes operate with H non-reset. In H non-reset, the exposure will be synch...

CV-M77 time (accumulation time) is governed by the fixed shutter speed set up by the rear panel DIP-switches or via RS-232C control. The resulting video signal will start to be read out after the selected shutter time. The WEN pulse indicates the start of valid video signal. Refer to timing charts f...

CV-M77 Set SW1-5 and SW1-6 on the rear plate of the camera to “ON” and SW1-7 to OFF or use the RS 232C control to set-up the PWC mode of the camera. 6.3.3 Frame-delay Readout Mode This trigger mode operates in H non-reset mode. In H non-reset mode the trigger and HD is synchronized. The exposure wil...
