Nexmosphere XD Series User manual
1. General
The X-Dot X can be attached to an object to sense whether it is moving or laying still. Typically, this feature is used to detect
if an object, such as merchandize in a store, is picked up or placed back. This document provides explanation of the available
functionalities and instructions on how to install and integrate the sensor 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 rst.

For pick-up detection, the X-Dot X utilizes an accelerometer to detect
whether it is moving or laying still. The sensor can be mounted to an
object using the double sided tape on the bottom of the sensor.
For security functionalities, the sensor has a phototransistor which
can measure the amount of light reaching the sensor. When the
sensor is mounted onto the merchandize, no light can reach the
sensor. When the merchandize is removed from the sensor (during
a potential security breach) light will reach the phototransitor and an
Alarm trigger is send. When the X-talk cable is cut, an alarm trigger
is send as well.
The X-Dot X wired pick-up sensor is available in multiple variations:

The X-Dot X wired pick-up sensor provides the following functionalities:
1. Pick-up and place-back detection - detect if an object is picked up or placed back
2. Security alarm functionality - detect if a product is potentially being stolen
When implementing pick-up or place-back detection,
consider the following:
• The sensitivity of the pick-up detection can be
adjusted. For more information please see Settings,
page 4.
• At start-up the sensor must lay still in order to make
sure it calibrates correctly. For more information
please see page 3.
• Typically, during testing/prototyping stages of a
project, the sensor is not yet attached to a product.
If this is the case and the security sensor is not
covered, the triggers will be with Alarm. Please take
into account that once the sensor is installed and
mounted onto an object, the triggers will be without
Alarm. Therefore we advice to always implement both
triggers into your application.
In case the Alarm trigger is activated as well, the output will
be as follows:
When an object is picked up, the sensor will detect the
movement and an API command is triggered. Vice versa,
when the object is placed back, it will detect that it is laying
still and an API command is triggered as well. These API
messages have the following format:
The X-Dot X will give an alarm trigger when the sensor
is removed from the product (and the light sensor is
uncovered) or when the X-talk cable is cut. The API
commands are the same as listed above:
The following sections will cover each of these functionalities in detail. Please note that for each API example in this
document, X-talk interface address 001 is used (X001). When the sensor is connected to another X-talk channel,
replace the "001" with the applicable X-talk address.

The X-Dot X wired pick-up sensor can be connected to any X-talk interface and is therefore compatible with all Xperience
controllers. Make sure the sensor is connected to the X-talk interface before powering the Xperience controller. Otherwise, it
will not be recognized by the Xperience controller and no sensor output will be provided.

At start-up, the X-Dot X auto-calibrates itself to its current
position. In order to assure the calibration process is
executed correctly, please make sure the sensor is laying
still in a stable position when powering the Xperience
controller to which the sensor is connected. Typically
when the sensor is attached to an object, this will be the
case due to the mass of the object. However when the
sensor is not yet attached to an object, we advice to
actively hold the sensor in a stable position for 5 seconds
during start-up.
The X-Dot X triggers based on whether is it moving or not. In order to make sure the place-back triggers are responsive, it is
important that both the object to which the sensor is attached, as well as the surface on which the object is placed, are stable
and don't move or oscillate. The sensor will only send a place-back trigger once it's position is stable. Moreover, a new pick-up
trigger can only be send after a place-back trigger has been send.

The X-Dot X has multiple settings which determine the behaviour and output of the sensor. The settings can be adjusted by
sending X-talk setting commands via the API. After a power cycle, the settings always return back to default.

The lower the sensitivity level, the least movement is
needed for the sensor to detect a pick-up, and the more
stable the sensor needs to be before it detects a place-
back. Vice versa, the higher the sensitivity level, the more
movement is needed for the sensor to detect a pick-up
and the less stable it needs to be before it detects a place-
back.
The setting above applies for the small green status LED in
the X-Dot X enclosure.

Via the setting above, both pick-up and alarm detection
can be enabled or disabled. In case the sensor model (see
overview on page 1) does not include pick-up or alarm
detection, it can't be enabled.

Step 1 - Setup
First, connect the X-Dot X to an Xperience controller.
Secondly, power the Xperience controller.
The green status LED of the X-Dot X should go on. The
status LED of the controller will start to blink and once
power-up is completed will be lit continuously.
Step 2 - Pick-up detection
Pick-up the sensor, or the object to which the sensor
is attached.
The green status LED of the sensor should go o and
the status LED of the controller should blink.
Step 3 - Place-back detection
Place the sensor back down, or the object to which
the sensor is attached.
The green status LED of the sensor should go on and
the status LED of the controller should blink.
For a full test we recommend to connect the setup to
a mediaplayer or PC and test all API commands listed
in this document (see section 3, page 2). For more
information on how to setup a test for your controller,
please see the Quick Start Guide of the Xperience
controller you are using. These are available on
nexmosphere.com/support-documentation
Please contact support@nexmosphere.com for any
support questions you may have.
In case any of the steps above does not provide
the expected result, please check the installation
guidelines in this document.
