Chapter 1. Introduction
Thank you for your purchasing the CAREU U1
Lite Vehicle Tracker. We are very pleased to
introduce you our excellent product, and you will
enjoy great benefits by applying such a smart
device. The CAREU U1 Lite Vehicle Tracker is
an all-in-one device that integrates multiple
applications of GPS (Global Position System),
GSM (Global System for Mobile Communication)
and GIS (Geographic Information Systems) with
each other.
Designed with the latest GPS technology, the
CAREU U1 Lite delivers positioning message by
GSM wireless transmission to GIS platform, and
then helps back-end users proceed with the
analysis and the applications of vehicle transport,
management, anti-theft, security and tracking.
1.1 Features
• Cost effective and easy installation
• SMS, GPRS TCP/ UDP, USSD, FTP communications
• Geo-fencing reports
• Remote configuration
• Real-time tracking (time, distance interval or intelligent mode, and heading)
• Intelligent power management
• Power low/lost alarm
• Journey report wireless downloads
• GSM/GPRS simultaneously
• Mileage report
• User-defined reports
• Firmware upgrade over the air (via GPRS from FTP)
• Up to 20,000 data log capacity

1.2 Scope
This document will guides you to start the CAREU U1 Lite Vehicle Tracker. However, as
this document contains basic device configuration only, please see the CAREU U1 Lite
Protocol Document for the advanced information.
1.3 About CAREU U1 Lite
The CAREU U1 Lite Vehicle Tracker transmits the wireless signals such as location,
peripheral, and vehicle control data to a control center. The onboard GPS receiver provides
users with location data including speed, direction, mileage and altitude. It uses an
onboard GSM/ GPRS module to accomplish wireless transmission.
A microcontroller can probe location and command data at regular intervals, derive actions
from location, peripheral and control data, and execute such actions.
Among the best features of the CAREU U1 Lite Vehicle Tracker, in particular, they transmit
data in ASCII mode or binary mode.
Peripheral data indicates the status of various peripherals connected to and/or controlled by
the device. The peripherals include, but not limited to, door locks/un-locks, starter interrupt,
ignition, battery, engine and panic button.
The firmware in the device applies intelligent filtering to overcome coverage limitations for
both GPS and GSM/GPRS networks.
Motion sensor controls the status of the device, whether in sleep, idle or fully-powered
mode, and thereby controls the amount of current consumed by the device.
Backup battery and tamper sensing GPS Antennas primarily indicate the loss of Main
Power and the interruption of GPS antenna connectivity.
The device supports over-the-air firmware upgrade to deliver additional functionality without
physically touching the device once installed.
In consideration of technicality and marketability, the CAREU U1 Lite has so many
excellences to be competitive enough to stand out in the market. With regard to the
technicality, the CAREU U1 Lite saves and records more data even under inactive
communication staus, and it also provides better power management, coexistence of GPRS
and SMS modes. When it comes to the marketability, the CAREU U1 Lite users are
provided with the convenience that its firmware can be upgraded through mini USB
without disassembling the device.

regulator, GPS receiver, GSM/GPRS modem, G-Force sensor, flash memory data
storage, I/Os interface and LED status indicators.
• Users can connect PC's HyperTerminal to the Diagnostic/setting port for the AVL
configuration.
• G-Sensor for car accident prevention, car tow-away warning and power management.
• The audio interface supports hand-free phone call.
• GPIO that connects to any customer monitoring points by door switch, anti-thief or
actuators.
• The A/D input that connects the analog signal sensor to the AVL, such as the fuel or
temperature sensor.
