1. Introduction
This document describes features, protocols and detail operation
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 GSM parts.
The main purpose of device reports getting 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 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, GSM 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)
Emergency is the first to be sent after recovering GSM condition.
The ST410 (i.e: the “Box Tracker”) is a tracking “device” to recover expensive merchandises
which are packed mainly with cartoon boxes and might be stolen while those merchandises are being transported from
the packing site to the destination(s).
GPS receives latitude and longitude.
The device (‘ST410’) transmits GSM information to its server and transmits its device ID (Identification number)
and GPS position.

2-3. Setting Parameter
Parameters of device can be changed by GSM 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 GSM 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 GSM.
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.
- 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.

Automatic GSM Set
It the device is set to ‘Automatic GSM Set’, the device set GSM parameters automatically depending on
inserted SIM.
For example, if Airtel SIM is inserted, the device set AUTH to 0, APN to “aitelGSM.com”, USER_ID and
USER_PASS to empty.
And the device reports response string after adding real GSM parameters when automatic GSM set is
selected.

** If report interval is set big number, network may disconnect GSM connection because GSM
communication is not progressed for a long time. So, unit may not receive command by GSM. 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 this parameter has been customized, This table should be disregarded and you should follow

operation document.
CON_TYPE
1. KEEP_CON : The device keeps TCP connection always and can receives a command by GSM.
2. KEEP_DISCON : The device connects TCP connection when the data is sent. After sending, the
device disconnects GSM and TCP connection if it estimates there is no data for sending within
3minutes. In this case, it cannot receive a command by GSM.
3. KEEP_NOP : The device doesn’t send any report after be installed. When the device enters
emergency mode or receive ‘Start Report’ command by SMS or RS232, it starts report depending
on report parameters. It may be used for saving GSM fee. Current version cannot support this
option.
Group Send
The device stores data if the vehicle is in no GSM area. And, the vehicle moves to GSM available area,
device starts sending stored data.
If group send option is enabled, the device makes 5 reports to one bundle and send these 5 reports at one
time.
Group send is useful to speed up sending.
M_Sensor
1. Collision: The device sending a event when ignition is ON and have a motion.
2. Shock: The device sending a event when ignition is OFF and have a motion.
Jamming detection procedure
JAM_CHK_DIST & JAM_CHK_TM are assist for jamming detection to avoid false detection.
At least, we recommend use JAM_CHK_DIST for safety.
If you use two assist functions, it can detect two case of jamming as follows.
*Case of jamming GSM only.
Jamming detected -> JAM_CHK_DIST -> JAM_CHK_TM -> Triggered by JAM_DET mode.
*Case of jamming GSM & 433.
Jamming detected -> JAM_CHK_TM -> Triggered by JAM_DET mode.
JAM_CHK_DIST : if 0, skip this function.
JAM_CHK_TM : if 0, skip this function.

ST410 User Manual

If disable all of assist functions, just triggered by HAM_DET mode after detected jamming.
In this case, it’s possible to false detection in weak GSM or strong radio area.

ACK in case of UDP
UDP is protocol that doesn’t check whether the data is transmitted successfully. So, the device checks
completion of sending with ACK depending on UDP_ACK type.
ACK is sent by server when the data is received.
If the ACK is not sent during more than 2 minutes after sending, the device recognizes the data was not
reached to server and sends the data again.
Examples of ACK report are as below.
