1. FUNCTIONAL DESCRIPTION
1.1. OVERVIEW
The XT4300 is used for asset tracking and tire monitoring services for fleets. The tire pressure monitoring
capabilities reduce tire-related costs, which subsequently reduces fleet costs from tire replacement and
expensive roadside service. The design engages the challenging industrial vehicle environment,
minimizing downtime and avoiding replacement expenses. The XT4300 features a powerful 32-bit
microprocessor and flexible power management algorithm, providing the capability of periodic reporting
of tire health, status, and location of remote assets. The device is designed to allow GPS tracking under
extreme conditions and leverages the latest tire pressure monitoring technology. The weatherproof case
(meets IEC 68-2-27 environmental standard and is IP67 certified) allows the XT4300 to be used for a
multitude of applications.

2. GENERAL OPERATION
The XT4300 is connected to the vehicle and communicates to the server via the cellular network in one of
two operating modes: tracking and snapshot.
While in tracking mode, the device operates in a continuous integration mode where it is receiving GNSS
solutions at a rate of 1Hz. When in tracking mode the device default state is ACTIVE, and the device will
enter HIBERNATE as a secondary state for low power.
While in snapshot mode, the device enables the GNSS receiver to obtain a 2D positional fix and then turns
off the GNSS receiver. This mode will have the GNSS off, the cellular modem off, and the microprocessor
in a deep sleep or hibernate mode of operation.
When in snapshot mode the device default state is HIBERNATE and the device will enter ACTIVE to capture
the state of the system, environment, and report that data along with data recorded from sensors while
in HIBERNATE to the customer’s application server

3. ELECTRICAL CHARACTERISTICS
3.1. MAXIMUM RATINGS
The maximum ratings are the limits to which the device can be subjected without permanently damaging
the device. Device reliability may be adversely affected by exposure to absolute-maximum ratings for
extended periods.
NOTE: The device is not guaranteed to operate properly at the maximum ratings.

3.2. CHARGING CIRCUIT
At 12 V the device may draw up to 380 mA from power supply.
This device uses a Synchronous Step-Down Battery charger with switchable charge rates:
Fast charge
Fast charge is enabled when Main Voltage is above 9.0 V and the temperature is above 0 degrees Celsius
(32°F). If Main voltage drops below 9 V, it needs to raise back up to 9.25 V to begin fast charging. Expect
to see up to 140 mA from Main Voltage Power supply (At 12.0 V).
Slow charge
Slow charge is enabled when Main Voltage is below 9.0 V or the temperature is between 0 and -20 degrees
Celsius (32° to -4°F). The device will enter a No Charge state if the voltage goes below 4.4 V. Expect to see
up to 50 mA from Main Voltage Power supply (At 8.0 V).
NOTE: Slow charging may lead to an insufficient charge for long-term operation.

No Charge
The XT4300 battery cannot charge outside of their charging temperature ranges. The device charges
between 0 to 45 degrees Celsius (32° to 113°F).
Once the battery charge drops below 3.4 V, the device will enter low battery where it will retain any
unsent events but will not generate any new ones. Once the device is charged to 3.6 V or greater, it will
publish events retained prior to low battery state and begin generating new ones.

4 REGULATORY STATEMENTS
4.1 FCC:
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
Changes or modifications made to this equipment not expressly approved by Xirgo Technology may void
the FCC authorization to operate this equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux conditions suivantes :
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le onctionnement.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type
and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec
une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada.
Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut
choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne
dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
This radio transmitter (IC:10281A-XT4392, Model Number: XT4392) has been approved by Industry
Canada to operate with the antenna types listed below with the maximum permissible gain and
required antenna impedance for each antenna type indicated. Antenna types not included in this list,
having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use
with this device.
Cet émetteur radio (identifier le périphérique par numéro de certification, ou le numéro de modèle si
Catégorie II) a été approuvé par Industrie Canada pour fonctionner avec les types d'antennes énumérées
ci-dessous avec le gain maximal admissible et l'impédance d'antenne requise pour chaque antenne type
indiqué. Types d'antennes ne figurent pas dans cette liste, ayant un gain supérieur au maximum gagner
indiqué pour ce type, sont strictement interdites pour une utilisation avec cet appareil.
