1. General
The X-Dot I/O can interface generic Input and Output devices to the Nexmosphere platform This document provides
explanation of the available functionalities and instructions on how to install and integrate the interface into your digital
signage installation.
The information in this document is created for users who are familiar with the Nexmosphere API and are able to control a
basic setup with a Nexmosphere API controller. If this is not the case yet, please read the general documentation on the
Nexmosphere serial API first.

The X-Dot I/O has a wire-to-board connector which allows
for connecting 3rd party I/O devices such as buttons,
pressure matts and relays to the Nexmosphere platform.
There are 3 connections: Input, Ground and Output.
When connecting
input devices
such as buttons, switches
or pressure matts, one wire needs to be connected to the
output pin and the other to the input pin. Typically, it doesn't
matter which of the 2 wires is connected to which pin, as
these types of IO devices simply make an interconnection
between the output and the input pin when activated (e.g.
button press or person on pressure matt).
When connecting
output devices
such as button LEDs or
relays. The supply (or +) wire -
typically red
- needs to be
connected to the output pin and the ground (or -) wire -
typically black -
needs to be connected to the ground pin.
