External Trigger Modes

This camera has 3 external asynchronous trigger modes, which can be set by RS-232C commands.
0. Async Reset
1. Edge Pre-select Mode.
2. Pulse Width Control Mode.
An external trigger pulse initiates the capture (input on pin 12 of the 15-pin connector). The falling edge of the
trigger pulse initiates the exposure and the duration of the pulse governs the exposure (accumulation) time.
The duration of the external trigger pulse must be greater than 1H. It is recommended to make this longer,
typically 9H.
3.2.2.1
The falling edge of the trigger pulse resets the image readout and initiates the start of a new frame. It then
operates in continuous mode until the trigger comes again.
To use this mode:
