This report describes an automatic strobecamera control unit for sensing when the TVstrobe power is on and the camera is enabled, and for automatically triggering the TVstrobe and camera at a preset time interval. An A.C. input voltage is divided to provide operator variable trigger pulse intervals and fixed 5 minute and 15 minute intervals for record annotation. A preset time interval is checked for error and controls a timer which provides a trigger pulse at the end of each interval. A decoder detects a command from a TV rack. An output keyclosure andor frame counter is disabled or enabled depending upon the decoded command. Author
