AeroScout T2u Wi-Fi Ultrasound Tag
Introduction 5
Introduction
The AeroScout T2u Tag is a key component of the AeroScout Visibility System. It is part
of the AeroScout Wi-Fi Ultrasound solution designed specifically for asset, patient and
staff tracking in healthcare environments, where knowing the location and status of
patients, staff and medical devices is critical to ensure the highest level of patient care, the
optimal use of resources and the most efficient workflows.
T2u works with Ultrasound Exciters. The Exciters transmit ultrasound signals, which do
not pass through walls, thus helping deliver location reports with room-level accuracy.
The T2u Tags, with embedded ultrasound receivers, capture the signals and report their
exact location over the Wi-Fi network.
When tags are not in proximity of ultrasound Exciters, they continue to transmit Wi-Fi
signals, which allow the system to determine their location within the hospital or facility.
T2u Tag Features
Ultrasound Receiver
The T2u Tag is equipped with an ultrasound receiver, which picks up the ultrasound
transmissions of EX4100 and EX4200 Ultrasound Exciters. The tag transmits the Exciter ID
over the Wi-Fi network. The tag is equipped with a proprietary dilution algorithm that
extends battery life.

T2u Tag Features 6
Motion Sensing
AeroScout T2u Tags contain on-board motion sensors. The motion sensor can be
configured to trigger alerts. It also enables different transmission intervals for tags when
they are stationary or in motion –which reduces unnecessary network traffic and
conserves battery life.
Call Button Functionality
An optional call button provides the capability to define events according to button
pushes –such as for emergency alerting or parts replenishment. The tag can be configured
to send different data depending on how the button is pressed: different messages can be
associated with a long push of the button and with short, successive pushes.
Flexible Mounting and Usage Options
A wide variety of mounting options are available for AeroScout T2u Tags –screw mounts,
adhesives, Velcro and tie-wraps, and wrist straps. An optional cradle allows mounting the
tag on a wide array of assets and in various environments.
Long Battery Life
A powerful, replaceable battery provides power for a period of up to 4 years. The Tag
periodically provides a report on the battery level so that when the battery level runs low,
it can be replaced efficiently with minimum down time. The AeroScout T2u Tag can also
be easily deactivated in order to conserve battery power.
Tag Management
The T2u Tag can be programmed via a wireless interface using the AeroScout Tag
Activator. Together with the AeroScout Tag Manager software it allows for easy and
efficient Tag configuration, activation or deactivation and programming.
Tag Programmability and Storage
The T2u Tag can store up to 15 messages of 10 bytes each. These messages can either be
pre-programmed via the Tag Manager or programmed on the fly by an AeroScout Exciter
when a tag is in proximity to it. These messages can also be transmitted in addition to the
standard location messages (the tags can be either configured to transmit one of the
messages or triggered by an AeroScout Exciter to transmit a specific message).
Active RFID Functionality
Using the AeroScout Exciter, the tag sends out specific location reports upon arrival at
chokepoints or gateways. The tag behavior can also be automatically modified while
passing through a chokepoint such as a doorway or gate. This includes
activating/deactivating tags or changing the tags’ transmission rate to accommodate
different usage patterns.

Compatibility and Non-interference
AeroScout Tags are 802.11b compatible. The tag’s clear channel sensing techniques avoid
interference with Wi-Fi networks. The use of the unlicensed 2.4GHz frequency band at low
power levels ensures no interference with other wireless equipment, making AeroScout
tags safe for use with such sensitive equipment as medical devices in a hospital.
Rugged Performance
AeroScout Tags are designed to function in harsh work environments and weather
conditions. The T2u tag enclosure is water-resistant (IP-65) and designed to withstand
significant physical shocks.
Tag Mounting
The AeroScout T2u Tag is enclosed in a compact case. It offers a variety of mounting
options described in this section.
Note
Make sure that the microphone on the front cover of the tag is uncovered.
Wrist Strap
Optional accessory - Can be used to strap the tag around the wrist.

Using the Mounting Cradle
The mounting cradle allows you to fix the tag on surfaces where it cannot be attached
using the adhesive material or the strap. Using the cradle, tags can be easily removed and
replaced without the need to handle adhesives.
Fixing the Cradle to a Surface Using Screws
Follow these steps:
1. Screw the cradle on the asset, using four screws.

2. Snap the tag into the cradle.
Securing the Tag to the Cradle
After snapping the tag into the cradle, it is possible to secure the tag to the cradle using a
strap.
Figure 7.
1. Thread the cradle strap through the middle strapping holes and through the tag's
back rail.

2. Tie the strap around the front of the tag.
Attaching the Cradle to a Pole
You can attach the cradle to a pole using two narrow straps. Follow these steps:
1. Thread the cradle strap through the two pairs of strapping holes.

2. Tie the straps to the pole.
3. Snap the tag into the cradle (or first tie the tag to the cradle and then attach it to the
pole).

T2u Tag Management 13
T2u Tag Management
The AeroScout T2u Tag can be configured, programmed and activated via a wireless
interface. This is done with the help of the AeroScout Tag Manager application and the
AeroScout Tag Activator.
In addition, Tag Manager is used to activate and deactivate tags and to program stored
messages on the tags.
The Tag Manager functions can also be activated via APIs that enable easy integration
with third-party applications.
Please refer to AeroScout Tag Manager User Guide and AeroScout Tag Manager API User
Guide.
Tag Maintenance
Replacing the Internal Battery
The AeroScout Tag uses one 3.6V Lithium Thionyl Chloride (LTC) ½ AA size cell. This
internal battery can last up to 4 years depending on the configured tag parameters (e.g. the
transmission interval rate).
Figure 12. T2u Tag Battery
To replace a battery:
1. Deactivate the tag with Tag Activator and Tag Manager (recommended).
2. Remove the rear panel by unscrewing the case screws.

Tag Maintenance 14
3. Carefully remove the old battery from the battery holder.
Note
Do not use a metal object to remove the battery.
4. Install a new 3.6V lithium Thionyl Chloride ½ 'AA' size battery in the battery holder.
WARNING: Use only batteries listed in Table 1 or batteries that have been
approved by AeroScout. There is a danger of fatal tag damage if the battery
is replaced incorrectly or by an incorrect type. Dispose used batteries
according to the instructions.
5. Close the rear panel.
6. Activate the tag.
7. Dispose of the old lithium Thionyl Chloride battery properly.
WARNING: Local regulations vary. Federal regulations allow up to 100
kg./month of lithium thionyl chloride batteries to be disposed in common
landfill. All leads (the terminals) should be taped to prevent short circuit.
The user is responsible for safe disposal.
