Digital I/O
The digital I/O interface provides an input and an output group, each containing eight signals. The
input group is electrically isolated from the output group. Both groups are also isolated from oth-
er VisionBox circuits and interfaces.
The following illustration shows the corresponding electrical equivalent circuit:

The input group requires an external connection of a shared GND reference. For the output
group, the user must provide a supply voltage to the VCC pin which is used by all output signals.
Every input and output have an LED to show the current state of the channel.
The connector arrangement is shown below:
