ST3500 User Manual

1. Introduction

This document describes features, protocols and detail operation of ST3500.

If there is another operation description document for special buyer to customize or model and

the contents of the document is different with this, customizing document should be applied for

special buyer.

2. Overview

Device consists of WCDMA, GPS and event parts.

The main purpose of device reports getting GPS position and other informs of vehicle to server

periodically.

Device can control or check connected lines and support additional functions.

2-1. Operation Mode

The device has 3 operation modes, driving, parking and emergency.

** Driving : Driving status when ignition is on.

** Parking : Parking status that starts if ignition is off during more than T1.

** Emergency : Once panic button is On or any other status as per designed.

The device sends emergency reports until A1 times or receiving server acknowledge.

2-2. Report

AVL reports GPS and some information at predefined interval, depending on the current modes.

Also, AVL sends some alerts, for example, movement at the parking condition, changing of

connected input line and so on.

Device distinguishes all reports with 6 types, Status report, emergency, event, alert, alive and

command response.

Device can store reports when reporting route (For example, WCDMA condition) is not successful.

Storage capacity is up to 2,000 status reports, 50 emergency reports, 50 alert reports (include

event reports) and 1500 bytes as command response. In case of status reports, oldest report is

erased and new report is buffered when the buffer is full and new status report enters (FIFO).

When reporting condition is recovered, device starts sending all buffered reports.

Also, this capacity can increase if it is needed.

Each type of reports has priority, and priority is as below.

Emergency Command Response Alert Status Report Alive (Lowest)

ST3500 User Manual

Emergency is the first to be sent after recovering WCDMA condition.

2-3. Setting Parameter

Parameters of device can be changed by WCDMA or SMS, and some control can be realized also

in the same way.

Detail protocols are described in Chapter 4.

2-4. Features

Key features are described here;

- Power Down

Device can process two steps of power-down, Sleep and Deep Sleep, for reducing power

consumption when the vehicle is parked.

- LED Indicator

LED indicates WCDMA and GPS states. It’s helpful to check error cause.

- Events

Device has 2 output lines, 3 input lines and ignition line.

- Update Firmware by Over The Air (FOTA)

When Firmware of device has some error or has to be changed for a new service to be

implemented, device can update internal ROM file by over the air (FOTA), remotely via WCDMA.

Customers do not need to visit every vehicle to download the new firmware.

Method of FOTA describes at “SunTech_OTA_UA_Protocol” document in detail.

- Parking Lock

Device can check whether the vehicle moves off the preset parking boundary or starts driving

without ignition on. In the case that it notes the unauthorized moving or driving, it sends

emergency report immediately.

- Over speed

Device can check speed of vehicle and send alert of over-speed to server.

- GPS Antenna Checking

Device can alert when GPS antenna is disconnected.

ST3500 User Manual

It’s applicable only for models that have external antenna.

- Main Power Checking

The device can recognize the main power and inform to server when main power line is

disconnected or main power drops below preset value.

It’s applicable only for battery model.

- Battery Error Alert

Device can alert about battery error related on charging.

It’s applicable only for battery model.

Automatic WCDMA Set

It the device is set to ‘Automatic WCDMA Set’, the device set WCDMA parameters automatically depending

on inserted SIM.

For example, if Airtel SIM is inserted, the device set AUTH to 0, APN to “aitelWCDMA.com”, USER_ID and

USER_PASS to empty.

And the device reports response string after adding real WCDMA parameters when automatic WCDMA set

is selected.

<notes>

** If report interval is set big number, network may disconnect WCDMA connection because WCDMA

communication is not progressed for a long time. So, unit may not receive command by WCDMA. T4 is for

protecting against this disconnection by sending short data with short term.

** Alive report can be sent only when the device has no data to send during T4 interval.

** If IGNITION is set to ‘0’, device doesn’t check driving or parking state of the vehicle. It reports status

string with idle mode always, and cannot support parking lock and the service that enters sleep or deep

sleep automatically when the vehicle is parked.

** If IGNITION is set to ‘2’, the device checks driving or parking state of the vehicle with voltage range of

vehicle’s battery. We named it as ‘Virtual Ignition’. Virtual ignition can operate when the device installed

into real vehicle and it may be need adjustment of voltage range for special vehicle. For setting method,

please refer 6.3.

** In case of pulse, pulse time may have tolerance about dozens of ms.

** Immobilizer, LED Blink line and Buzzer type cannot set both OUT1 and OUT2 simultaneously.

** In case that a event is set to “door sensor”, active state means door is opened.

** If device has the Handsfree kit, each time the volume up button is pressed once, the speaker volume is turned up as below.

0 -> 1 -> 2 -> 3 -> 4 ->5 ->0 -> 1 -> 2 ->3 -> 4 -> 5 - > 0 -> 1 -> ….

(0 : Volume mute, 5 :Max Volume)

Type of no supported event line is fixed to “No Use”.
