For interpreting the trigger signal, either the positive or the negative edge can be used. The digital
input 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 digital input 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).
