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. 1.2. MECHANICAL Mechanical Dimensions Weight Operating Temperature Charging Temperature 2.07" x 2.46" x 7.6" (52.7 x 62.6 x 193 mm) TBD

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 customers application server 2 INSTALLATION PROCEDURE 2.1 TERMINOLOGY Term Description Unit Asset Xirgo XT6264 Customer product that the XT6264 is mounted to. 2.2 INSTALLATION The Unit can be wire-tied to the Asset under the trailer chassis beam with its own Wiring Harness Connected.

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. Parameter V_IN Parameter Name V_IN supply voltage Min 8.0 Max 30.0 Unit V Current Consumption (Measured when supplied 12V) Idle Active Network Active Network - GPS Off Battery Charging - FAST MODE min(mA) max(mA) 31 68 58 365 52 91 81 380 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

(32F). 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 -4F). 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. CONFIDENTIAL AND PROPRIETARY Disclosure, storage and use subject to non-disclosure agreement P a g e 6 | 10 XT4392 User Guide No Charge The XT4300 battery cannot charge outside of their charging temperature ranges. The device charges between 0 to 45 degrees Celsius (32 to 113F). 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.

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 interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Connect the equipment into an outlet on a circuit different from that to which the receiver is Increase the separation between the equipment and receiver. connected.
