1.2 Scope
This document will guides you to start the CAREU U3 Vehicle Tracker. However, as this
document contains basic device configuration only, please see the CAREU U3 Protocol
Document for the advanced information.
1.3 About CAREU U3
The CAREU U3 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 U3 Vehicle Tracker, in particular, they transmit data
in ASCII mode (Intellitrac X Series compatible 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 U3 has so many excellences
to be competitive enough to stand out in the market. With regard to the technicality, the
CAREU U3 saves and records more data even under inactive communication staus, and
it also provides better power management, coexistence of GPRS and SMS modes, 1-Wire
®
interface, direct connection to Temperature Sensor, and up to three serial ports. When it
comes to the marketability, the CAREU U3 users are provided with the convenience that
its firmware can be upgraded through mini USB without disassembling the device.

3.4 USB Device Driver Installation
The CAREU U3 communicates with your host computer by either RS-232 or USB
interface.
In some newer editions of Windows XP, the CAREU U3 device can be installed as a "virtual
COM port" device whereby the CAREU U3 would automatically access Windows XP's
inbox USB drivers. While in some other earlier editions of Windows XP, you would need to
manually install the USB driver for the CAREU U3 device. In the following content of this
section, you will be guided to how the installation can be done in both cases.
To install the device driver for the CAREU U3, connect the CAREU U3 device to your
system with an USB cable as mentioned in Mini USB Cable Connection on page 11.
As soon as the connection is made between the CAREU U3 and your computer, a balloon
appears above the notification area saying an USB device is found.
Click on this balloon to start the [Found New Hardware] wizard.
Select No, not this time. Press the Next button to proceed.
