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.
