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...
