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
Camera Properties: Input/Output section).
Digital output wiring
The following figures show examples of how the digital output is wired.
