The digital output is galvanically isolated using an opto coupler to protect the camera and the PC against surges.
Only DC voltages may be applied to the digital input.
The output of the opto coupler can be used as an open collector or open emitter output. This means that the output
signal can be connected to ground or to the supply voltage. The output signal is active if the collector-emitter switch
is closed (software setting: Flash high active, see also the
Digital output wiring
The following figures show examples of how the digital output is wired.
