Suntech can also increase this capacity up to a certain level if a customer of the device wants to do so. As soon as
the reporting condition for the device is recovered, the device starts sending all those accumulated reports
according to the following rule:
- Emergency (the most important)
Command Response
Alert
Status Report
Alive (the lowest priority)
This means that the emergency report is the first one that should be sent right after the GPRS network condition is
recovered.
2-3. Parameter change
Parameters which have already been set on the device can be changed via GPRS or via SMS or via RS232
connected with PC/ST50if a user needs to do so. Some controlling functions can also be implemented in the same
way.
How to change values of the current parameters is described in detail in Chapter 4 of this document.
2-4. Features
Key features of the ST300device are as follows:
- Power Saving Modes (Power Down Modes)
- LED Indicators
The LEDs indicate GPRS and GPS status. It is helpful to check what error(s) and why such an error has
occurred.
- Event Lines
Device has 2 output lines, 3 input lines and one ignition line.
** The ST300F uses the <OUTPUT2> line to control power for the fuel sensor(s).
- Upgrading Firmware by Over The Air (Firmware OTA)
In case
‘firmware’ of the device has an (some) error(s) or needs to be upgraded to provide the user with
newly implemented services, the device can upgrade its internal ROM file by over the air (Firmware OTA),
remotely via GPRS. The users do not need to visit the vehicle individually to download the new firmware on
those vehicles.
How to do OTA is described in detail in the
“SunTech_OTA_UA_Protocol” document.
- Parking Lock
Device is able to check if the vehicle moves away from the pre-defined parking boundary or starts moving
without having a mode of the ignition on. In case the device recognizes such an unauthorized moving or
driving, it sends an emergency report immediately.
- Over-Speed
Device checks speed of the vehicle and sends to the server an alert if the vehicle runs faster than the
predefined over-speed threshold values.
- Checking Connectivity of GPS Antenna
