1.2. Scope
This document will guides you to start CAREU U1 Vehicle Tracker. However, as this
document contains basic device conguration only, please see CAREU U1 Protocol
Document for the advanced information.
1.3. About CAREU U1
CAREU U1 GPS 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 AVL U1 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 rmware in the device applies intelligent ltering 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 rmware upgrade to deliver additional functionality without
physically touching the device once installed.
In consideration of technicality and marketability, U1 has so many excellences to be
competitive enough to stand out in the market. With regard to the technicality, U1 saves
and records more data even under inactive communication staus, and it also provides
better power management, coexistence of GPRS and SMS modes, 1-wired interface,
direct connection to Temperature Sensor, and up to three serial ports. When it comes to the
marketability, U1 users are provided with the convenience that its rmware can be upgraded
through mini USB without disassembling the device.

3.3. USB Device Driver Installation
CAREU U1 communicates with your host computer by either RS-232 or USB
interface.
In some newer editions of Windows XP, the U1 device can be installed as a "virtual COM
port" device whereby U1 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 U1 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 U1,
Connect the U1 device to your system with an USB cable as mentioned in USB Cable
Connection on page 10.
As soon as the connection is made between U1 and your computer, a balloon appears
above the notication area saying an USB device is found.

3.5. Communication Settings
CAREU U1 Vehicle Tracker communicates with your control center by either SMS or
GPRS (TCP/UDP). Before the device is installed into a vehicle, communication parameters
should be set.
1. SMS Conguration
Use AT$SMSDST command to set a SMS control center phone number or short code.
For example, if the SMS control center phone number is +886123456789, the
AT$SMSDST command to be issued into HyperTerminal should be:
AT$SMSDST=+886123456789
OK
Then you can try to use cellular phone or SMS gateway to send a SMS message to
the U1 device. Send a SMS message --> "AT$MODID?"
Device will response:
$MODID=101000001
OK
This proves a successful mobile phone SMS connection.

3.6. GPS Tracking Congurations
After the device communication settings are done, the remote GPS tracking is ready to
function. The setting of GPS tracking can be done by using AT$PDSR command. For
example,
AT$PDSR=1,30,0,0,2,0,0,1,1 (Tracking through GPRS by time interval 30 seconds)
OK
For simple testing GPRS, run the TCP Server U-Series software which is provided by
S&T. It is simple server software that can wait for device connection and data.
