3. Functionalities and API commands
The XF-P3 wireless pick-up sensor provides the following functionalities:
1. Pair to EM-F base station - to send wireless X-talk messages when triggered
2. Pick-up and place-back detection - detect if an object is picked up or placed back
3. Auto-shutdown during transport - detects if the sensor is in transport to save battery life
4. Unpair from EM-F base station
3.1 - Pair to EM-F base station
As the XF-P3 sensor communicates wirelessly, it needs to be paired to an EM-F base station in order to generate API
messages when the sensor detects a pick-up or place-back. There are 2 methods to pair an XF-P3 sensor to a Wireless
X-talk channel of an EM-F base station: Pair button or API command. Before starting the pair procedure, please check the
following:
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 111 is used (X111). When the sensor is connected to another X-talk channel,
replace the "111" with the applicable X-talk address.
• Make sure the XF-P3 sensors are switched ON and
that they lay still. The green LED on the sensor will
briey go on right after the device is switched on.
• When using an XF-P3Nsensor, please make sure to
place a CR2032 battery before starting the pairing
procedure. The XF-P3Wand XF-P3Bsensor already
have a battery placed within the enclosure.

API command method
1. Send the command [PAIR] to the channel you want to pair.
For example: if you want to pair a XF-P3 sensor to channel 111, the API command is
The green LED of the selected channel will start to blink to conrm it is in pairing mode.
2. To pair: pick-up the sensor you want to pair to the selected channel.
The green LED of the paired channel will be lit continuously for 1 second to conrm pairing was successful.
3. Right after, the main LED of the EM-F base station will blink 3 times to conrm exit of pairing mode.
Regardless what pairing method is used, an XF-P3 sensor only needs to be paired one time. After a power cycle it will remain
paired. Please note that a sensor can be paired to multiple base stations. So when pairing, please make sure that no other
sensors are accidentally lifted and paired.
X111B[PAIR]
When implementing pick-up or place-back detection,
consider the following:
• The sensitivity of the pick-up detection and place-
back detection can be adjusted. For more information
please see Settings, page 7.
• The measuring method for pick-up and place-back
detection can be adjusted to suit dierent applications.
For more information please see Settings, page 7
• When an XF-P3 sensor detects a pick-up, the status
LED of the Wireless X-talk channel on the EM-F base
station will go on.
• When an XF-P3 sensor detects a place-back, the
status LED of the Wireless X-talk channel on the EM-F
base station will go o.
• In order for a pick-up to be detected, the sensor must
rst have detected a place-back.
3.2 - Pick-up and place-back detection
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:
Object is picked up
Object is placed back
X111A[3]
X111A[0]
place-back
pick-up
Example API messages
XF-P3 sensor paired to channel 113 is picked-up

3.3 - Auto-shutdown in transport
The sensor needs to be switched o before shipment, in order to make sure the battery won't drain. In case the sensor
is still switched on during transport, it has the ability to detect this and shutdown automatically. It does so by combining
movement data with (the lack of) communication data with an EM-F base station. This feature can be enabled or disabled via
the following API commands:
X111B[AUTOSHUTDOWN=ON]
X111B[AUTOSHUTDOWN=OFF]
Disable auto-shutdown
Enable auto-shutdown (default)
When the sensor has shut down automatically, it can be switched on again by rst switching the sensor o, and then
switching the sensor on (see page 2). Even with auto-shutdown enabled, the sensor will still drain unnecessarily when left
on during transport. It is therefore still highly recommended to switch the sensor o before shipment.
API command method
1. Send the command [UNPAIR] to the channel you want to unpair.
For example: if you want to unpair channel 111, the API command is
The green LED of the unpaired channel will be lit continuously for 1 second to indicate which channel was unpaired.
Simultaneously, the red Unpair LED of the EM-F8 will be lit continuously for 1 second to conrm unpairing.
Unpair button method
1. Hold control button B for a few seconds.*
The red Unpair LED (E) will start to blink.
2. To unpair: lift the sensor which you want to unpair from the selected channel.
If the picked-up sensor was paired to a channel on the EM-F8, the green LED
of the unpaired channel will be lit continuously for 1 second to indicate which
channel was unpaired. Simultaneously, the red Unpair LED of the EM-F8 will be lit
continuously for 1 second to conrm unpairing was successful.
*Tip: use a pen or small screwdriver to press the buttons
• Make sure the XF-P3 sensors are switched ON and
that they lay still. The green LED on the sensor will
briey go on right after the device is switched on.

Typically the sensor is applied in Lift&Learn applications for larger-sized merchandize such as footwear, or handbags. In
these scenarios, the sensor can simply be placed inside the object (e.g. shoe). In case the sensor must be adhered to an
object, we recommend using industrial grade double-sided tape. For projects in which a dierent formfactor is required and
you want to design your own custom casing, the XF-P3N sensor (without casing) can be applied.

Battery life
The battery life of the XF-P3 sensor is determined by the number of pick-ups and average pick-up time. When laying still,
the sensor's power consumption is neglectable. In the table below, an indication is given of the battery life in various usage
scenarios.

To prevent battery drainage, it is important to switch the sensor o during transport. Although the sensor's auto-shutdown
feature is enabled per default, it will still drain the battery unnecessarily if it is switched on during transport. For more
information on the sensor's auto-shutdown feature, please see page 4.
Battery level indication
The battery level is indicated via the status LED on the sensor, right after it is switched on. The number of blinks indicates the
battery life.
• 3x blink high battery level
• 2x blink medium battery level
• 1x blink low battery level

The XF-P3 sensor has multiple settings which determine the behaviour and output of the sensor. The settings can be adjusted
by sending X-talk setting commands. The settings will be applied when picking up the sensor after the setting command has
been send to the EM-F base station. After a power cycle of the EM-F base station, the settings return back to default.

Setting 8: Pick-up detection mode
1. Relative mode (default)
2. Absolute mode
The sensor continuously measures it's X, Y, Z position to
detect if it is being moved (picked up) or laying still (placed
back).
The detection method for a pick-up is per default set to
Relative mode. This means that the delta of consecutive
measurements of it's position determines if there was
enough movement to be classied as a pick-up. In practice,
this means that in case the sensor is moving very slowly,
or only rotating over 1 axis, no pick-up will be detected ,
as the delta between two consecutive measurements is
too small. It also makes sure that small movements won't
cause any ghost pick-ups. Relative mode (setting 8:1) is the
recommended mode for lift & learn scenarios.
When set to Absolute mode (setting 8:2), the delta is
measured over the current positions vs the home position
(place back position) of the sensor. In practice, this means
that even when the sensor is moving slowly or only rotating
over 1 axis, a pick-up will still be detected. This mode is
recommended for applications in which the sensor is
attached to objects which have a xed rotation point, for
example to detect if a door is being opened.
The setting determines how much movement there needs
to be for the sensor to detect a pick-up. Level 1 is the most
sensitive option, meaning that little movement is required
for the sensor to detect a pick-up. Level 10 is the least
sensitive option, meaning that more movement is needed
for the sensor to detect a pick-up.
The setting determines how steady the sensor needs
to be for it to detect a place-back. For sensitivity level 1,
the sensor must be least steady for a place-back to be
detected. For level 10, the sensor must be most steady for
a place-back to be detected.
When the XF-P3 doesn't receive an acknowledgement
from the EM-F that a wireless message has been received,
it will resend the message. Setting 10 determines how many
repeats of a resends the XF-P3 message will transmit.

Setting 7: Number of home positions
Set number of home positions
X is a value between 1-10 and its default value is 2. It
sets the number of home positions which the sensor can
store. When the sensor detects a placed-back, it's current
position is automatically stored as "home position". When
the sensor is placed back in the same position as a stored
home position, it detects a place-back faster.
