Can the forum provide a circuit schematic or description for an external 5V TTL triggering circuit that has been I/F'ed between camera and PC?
If a S/W approach is available, please advise?

will be measuring a rotational device.  Require to trigger camera on/off when the command to start and stop the motion is executed. Duration of mechanical motion is no greater than 400msec. Command signal to execute motion is provided remotely to a processing board/GPIO board which is connected to the remote source via windows OS computer.  camera is also operated through computer which is also controlled remotely from same source that motion command signal is issued.
What is a method to provide trigger to camera when motion command signal is executed as well as stop camera recording when motion command signal is completed.
