Opto-isolated Output (Pin 4/Line 2)

The camera is equipped with one dedicated opto-isolated output line designated as Line 2. The
output line is accessed via the 6-pin connector on the back of the camera (pin 4, see
In addition, the camera has two direct-coupled GPIO lines, Line 3 and Line 4, that can both be used
as output lines. They are described in Section 5.9 on
The opto-isolated output line has the advantage of being distinctly more robust
against EMI than a GPIO line used as an output. However, when using the opto-
isolated output line, the delays involved are longer than for a GPIO line.
