this document contains basic device configuration only, please see the CAREU WT1
Protocol Document for the advanced information.
1.3 About WT1
The CAREU WT1 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 WT1 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 WT1 has so many
excellences to be competitive enough to stand out in the market. With regard to the
technicality, the CAREU WT1 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 WT1 users are
provided with the convenience that its firmware can be upgraded through mini USB
without disassembling the device.
