help back-end users to proceed with the analysis and
the applications of vehicle transport, management, anti-
theft, security, tracking, to name a few.
Cost effective and easy installation
SMS, GPRS TCP/UDP, USSD, FTP communications
Geofence 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 120,000 data logs
1.2 Scope
This document will guides you to start the CAREU U1 Lite(WR) Vehicle Tracker. However,
as this document contains basic device configuration only, please see the CAREU U1
Lite(WR) Protocol Document for the advanced information.
1.3 About CAREU U1 Lite(WR)
The CAREU U1 Lite(WR) 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/GPRSmodule 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(WR) 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. The firmware of the CAREU U1 Lite(WR) can
be upgraded through USB without disassembling the device.
In consideration of technicality and marketability, the CAREU U1 Lite(WR) has so
many excellences to be competitive enough to stand out in the market. With regard
to the technicality, the CAREU U1 Lite(WR) saves and records more data even under
inactive communication status, and it also provides better power management,
coexistence of GPRS and SMS modes.
1.4 Hardware Architecture
As hardware is concerned, the CAREU U1 Lite(WR) is comprised of a micro-controller,
regulator, GPS receiver, GSM/GPRS modem, G-Force sensor, flash memory data
storage, I/O 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.

Chapter 3 Getting Started with CAREU U1 Lite(WR)
To install the CAREU U1 Lite(WR) vehicle tracker, follow the instructions below for basic operations.
3.1 Hardware Installation
1. SIM Card Installation
●Remove the cap. Insert SIM card into SIM card slot.
2. GPS Antenna Connection
● Connect the GPS antenna to the SMA connector jack on the front side of the device
(circled as the illustration below) by completely screwing the GPS antenna's plug
connector.
● It is recommended that a matching torque 7-10 inch pounds (80-110 N.cm) should
be used for the SMAconnector
3. G-Sensor Installation Consideration
The device uses a 3-axis G-Force sensor to detect the vehicle motion and the impact
on the vehicle. The X, Y and Z axis definition will be affected by the location of device
installation.
