4 Interfaces
4.1.1
Digital I/O
The digital I/O interface provides two opto-isolated inputs and four opto-isolated outputs. The input group
is electrically isolated from the output group. Both groups are also isolated from other VisionCam circuits
and interfaces.
The following illustration shows the corresponding electrical equivalent circuit:

The input group requires external connection of a shared GND reference.
For the output group, the user must provide a shared supply voltage to the VCC pin. See chapter 4.1 for
the connector pinout.
