Introduction

The ST4950 is a asset tracker for a vehicle. It is designed to collect location data through GPS technology and interact remotely with its server by using GPRS/HSPA technology.
In order to make the vehicle tracking system work, device should be configured and installed properly on a vehicle whose geographical position and/or state is desired to be remotely monitored and/or controlled.
Please note that this Operation Manual is for the standard model. In case specific requirements are incorporated into this Manual, such a manual applies only for the case.
For overall operation including installation, in addition to the ‘Device Manual’, users should refer to other documents such as Parameter Manual, Commands Manual, Reporting Manual and so on.

Overview

Main function of device installed on a vehicle is to report vehicle location and status to its monitoring server at predefined interval and to deliver command coming from the server for activating any appliance connected to the device.

Operation modes
The device works in one of the two (2) operation modes below.\

• Parking mode:
  ✓ This mode is operational when ‘MOTION’ is OFF for duration longer than the pre-defined time or ‘motion sensor’ is disabled.

• Driving mode:

• This mode starts when ‘MOTION’ is ON for duration longer than the pre-defined time.

Reports sent by device

There are 2 types of report/response sent by device to the server as follows:

• ✓ Status Report
• ✓ Alerts Report

Parameter change
Parameters that have already been set on the device can be changed via GPRS/HSPA or via SMS or via RS232 connected with PC if a user needs to do so. Some controlling functions can also be implemented in the same way.

Features
Key features of the ST4950 device are as follows:

Unified Protocol

• ✓ Support standard report format fixed to all models.
• ✓ Customer can select only the data they want from the data included in the report, so that they can configure their own report format.

Power Saving

• The device can save power consumption of the battery according to options. ( motion sensor and tracking time )

LED Indicators

The LEDs indicate GPRS/HSPA and GPS status. It is helpful to check what error(s) and why such an error has occurred.
Please refer to Chapter 3-1

Maintenance server support
Upgrading Firmware by Over The Air (Firmware OTA)

Alerting Battery Low & Shutdown
Device sends an alert or will be shutdown when a battery voltage is lower than pre-defined.

DETAILED DESCRIPTION

Indication with Two(2) LED

RED LED indicates GPS status and blue LED indicates GPRS/HSPA status.

Red LED for GPS

1.  If power is on, GPS chipset tries to find position for some minutes.

2.  If device has weak connectivity with GPS network or if it has no GPS signal position.

3.  If GPS connectivity with a device is weak.

GPS Chipset Error GPS Antenna Error| 4| < Probable Situations>

1.  If GPS antenna is disconnected.

2.  If GPS antenna or socket of GPS antenna is broken.

3.  If device is broken.

Blue LED for GPRS/HSPA

< Probable Situations >

1.  If the server or network parameter is wrong.

2.  If the server is closed.

3.  If there is a temporary network barrier.

GPRS/HSPA Com.

Error

| 3| ****

< Probable Situations >

1. If network parameter is wrong.

2.  If SIM is blocked and it is impossible to use GPRS/HSPA session.

3.  If there is a temporary network barrier.

4.  If device receives weak GPRS/HSPA signal.

5.  If GPRS/HSPA connectivity with a device is weak.

No Network| 4| ****

< Probable Causes>

1.  If GPRS/HSPA antenna is disconnected.

2.  If GPRS/HSPA antenna or socket of GPRS/HSPA antenna is broken.

3.  If the device is broken.

---|---|---
SIM PIN Locked| 5| < Probable Situation >

1. If SIM PIN is enabled.

Cannot Attach NW| 6| < Probable Situations>

1.  If device receives weak GPRS/HSPA signal.

2.If GPRS/HSPA connectivity with a device is weak.

No SIM| 7| < Probable Situations >

1.  If there is no SIM or if SIM is not inserted properly.

2.  If SIM or SIM socket is broken.

SIM PUK Locked| 8|

1. If SIM PUK is enabled.

Power Saving
Device turns off GPS and GPRS/HSPA parts except for time to send the report. All communication with the server is impossible and it cannot receive any SMS messages. If GPRS/HSPA wakes up for sending the report, will be responded to message received.

Turn On/Off – Turn ON
If you put a magnet on the sensor position for more than 2 seconds, the device will be turned on. Then Red and blue LEDs blink together twice. When the power is on, Red LED will be light for 3 seconds.
Turn OFF
If you put a magnet on the sensor position for more than 2 seconds when the device is turned on, the device will be turned off. Then Red LED only blink six(6) times. When the power is off, Red LED will be blink once a second.

Storage of Reports un-sent
The device has maximum storage capacity of the un-sent reports in such cases as follows:

Note

Due to bad report-routing environment, device could not make a real-time based reporting. For example, the reporting router does neither run properly, is nor connected properly. In such a situation there might be a report which has consequently failed to arrive in the server successfully after making several attempts to send the report to the server. In that case, the device stores such a report for a while until such environment (e.g. GPRS/HSPA network) gets back to normal to enable the device to try to send the report to the server again.
When ‘reports’ start being accumulated, max 2000 reports can be hold in the buffer storage of the device. If those ‘reports’ are triggered out to the server, the oldest report is erased first and a new report is buffered if the buffer is completely full of those reports. And then, a new status report enters (FIFO: First In First Out as a sequential system).
