3.4 Trigger input
The device software provides stimulation functions via the Trigger input. The trig-
ger actions are configured via software. If a voltage pulse is supplied on the Trig-
ger input, the configured trigger action is executed. The supplied voltage pulse is
analyzed in the device via an optocoupler.
