The digital trigger command is sent via USB to the video I/O hub and executed by the device once the instructions are received. Intended use: send a message to a third-party device. Useful to send ‘messages’ to facilitate post-processing or operate a juice pump.
Mode: Selects which types of trigger to send:
“PositivePulse”: for a single square wave pulse voltage change from 0V to 5V, returning to 0V.
“NegativePulse”: single square wave pulse voltage change from 5V to 0V, returning to 5V.
Digital Output: The digital output value you want to trigger. Please note that this is not the pin number, the mapping of a pin to the digital output can be found in the respective user manual.
Duration: Defines the duration of each pulse, in milliseconds. In other words, how long will it stay at 0V or 5V before returning to its initial state.
Duty Cycle: Ratio of which the signal stays in the positive or negative state.
Repetitions: Specifies how many times the trigger pulse should be repeated, typically a single repetition.

Screenshot from LabMaestro Public Beta 1.6.0
In the above screenshot, on Digital Out 0 (Pin 1), there will be a 0.5 sec (half the duration) positive trigger, bringing the value from 0 to 1 and then back to 0.
