5.7 Opto-isolated Input (Pin 2/Line 1)
The camera is equipped with one dedicated opto-isolated input line designated as Line 1. The input
line is accessed via the 6-pin connector on the back of the camera (pin 2, see
Figure 34 ).
In addition, the camera has two direct-coupled GPIO lines, Line 3 and Line 4, that can both be used
as input lines. They are described in Section 5.9 on
page 63 .
5.7.1 Electrical Characteristics
The opto-isolated input line has the advantage of being distinctly more robust
against EMI than a GPIO line used as an input. However, when using the opto-
isolated input line, the delays involved are longer than for a GPIO line.
