General Introduction
This document defines the protocols for establishing, managing & maintaining a GSM session (SMS or GPRS) with NaxerTech
NTT-101 device and the Server Base Control.
NTT-101 device acts as a mobile data station in an SMS (Short Message Service) or GPRS (General Packet Radio Service)
network. General Packet Radio Service is a radio technology for GSM networks that adds packet-switching protocols, shorter
set-up time for ISP connections. It is a new non-voice value added service that allows information to be sent and received
across a mobile telephone network. Allowing information to be transmitted more quickly, immediately and efficiently across
the mobile network, GPRS can provide instant connections subject to radio coverage. No dial-up modem connection is
necessary.
The GSM session protocols defined in this document includes communications sequences and send/receive data formats.
Unit Initialization
In this section SMS communication initialization and GPRS initialization protocols are discussed.

If max speed violation occurs, the device will send GPS data and status of the Control Base
through GPRS or SMS (backup). The Control Base shall return a PDU packet containing address
details and alert test in order to let the device send the text message to authorized contact
number. If no GPRS connection can be established, the SMS terminal at the Control Base shall
send SMS messages to authorized contact numbers itself.
%GPRS,0
Configure device to send data SMS if GPRS connection cannot be established at all occasions.
%GPRS,1
Configure device to send data only through GPRS. SMS fallback will only be used in case of
alarms.
Note:
When entering INI/ INO commands leave unassigned parameters empty but always include the comma. (,)
In all the commands there is no space after the comma.
Control Center Number and Unit ID issued by the Control Base software cannot be changed after the initial %INI/ %INO
commands have been implemented.
Any further initializations with changes in Control Center Number have to be sent using the original GSM n umber, before you can
switch to a new Control Center Number.

E. Tracking Commands
This section will help implement how to setup tracking period and interval, start, stop tracking and how to implement the
real time tracking.
Tracking –Real-Time
Format
%TRACK,1,UploadInterval
%TRACK,1,UploadInterval
This command enables real time tracking and unit sends its GPS data & status via
GPRS or SMS to Control Base after every upload interval time. Minimum Upload
Interval time is 60 seconds.
Interval: (Min 60 seconds, Max 65535 seconds)
Example 1
%TRACK,1,300
Tracking
Command
TRACK
Tracking Mode
1 –Represents Real-Time tracking mode
Interval
300 seconds
Unit sends the location and status to the Control Base after every 300
seconds (5 minutes).
Example 2
%TRACK,1,7200
Tracking Command
TRACK
Tracking Mode
0 –Represents Real-Time tracking mode
Interval
7200 seconds
Unit sends the location and status to the Control Base after every 2 hours.
Tracking –Store & Upload (Interval Based with Buffer)
Format
%TRACK,2, UploadInterval,Distance(metres),StationaryInterval (optional)
%TRACK,2,UploadInterval,StoreInterval
This command enables interval based tracking with storage on EEPROM. Unit will
store GPS location and status data after every specified storage interval (in
seconds) to its memory and will send to Control Base after every specified
upload interval (in seconds) and will clear sent position from its memory.
Store and Upload Track command can also have optional 3rd parameter named
“Stationary Interval” like
%TRACK,2,UploadInterval,StoreInterval,StationaryInterval.
If this 3rd parameter is present then a MINDISTANCE of 50 metres will
automatically be applied.
If a non-zero %MINDISTANCE is applied to unit, then it will not send location
&status data till the distance criteria met or with the stationary interval defined.
In this way unit data traffic can be reduced while getting maximum motion
values. So if unit is moving, location will be stored every “StorageInterval”
seconds. But if unit is stationary, location will be stored every
“StationaryInterval” seconds.
UpLoadInterval: (Min 60, Max 65535 seconds)
StoreInterval: (Min 60, Max 65535 seconds)
StationaryInterval: (Min 60, Max 65535 seconds)

%TRACK,3,UploadInterval,Distance
This command enables distance based tracking. Unit will store GPS location and
status data after every specified distance interval (in meters) to its memory and
will send to Control Base after every specified upload interval (in seconds) and
will discard that location. If the upload interval is complete but specified
distance is not yet covered, unit will not send any location to Base Control.
Upload Interval: (Seconds: Max 65535 seconds)
Distance: (Metres: Max 60-65535 meters)
Example 1
%TRACK,3,300,500,3600
Tracking Command
TRACK
Tracking Mode
3 –Represents Distance Base tracking mode
Upload Period
300 seconds
Distance
500 metres
Unit will store its location after every 500 meters and will send it to Control
Base after every 300 seconds (5 minutes). If distance condition is not met
then it will send location after every 3600 seconds (1 hour).
Example 2
%TRACK,3,7200,1000
Tracking Command
TRACK
Tracking Mode
3 –Represents Distance Base tracking mode
Upload Period
7200 minutes
Distance

Unit will store its location and status after every 1 kilometre and will send it
to Control Base after every 2 hours.
Tracking –Motion
Format
%TRACK,4, UploadInterval,Distance(metres)
%TURNS,X
Settings are similar to STORE/UPLOAD tracking mode but with an addition that
whenever a motion is detected from accelerometer (motion sensor) and Storage
Interval has passed, a location will be stored for sending to server.
Example 1
%TRACK,4,60,30
Tracking Command
TRACK
Tracking Mode
4 –Represents Motion mode
Upload Interval
60 seconds
Store Interval
30 seconds
This will store a location maximum one per 30 seconds if any movement
detected.
Tracking –Turn Based
Format
%TURNS,X
%TURNS,X
Instructs unit to store/send a location whenever the vehicle turns more X
degrees where X is in degrees ranges from 0 to 360.
This is very useful command to allow accurate mapping of tracks when vehicle
turns in the streets or goes around bends. 20 degrees turn setting is an optimal
one.
Example 1
-
Note:
On successful receipt of %TRACK command, unit will respond with confirmation of new settings.
The unit will confirm by sending back the first data packet or SMS right after placing the %TRACK command.
No phone calls or other SMS commands will be received during Real Time Tracking or other features that require the unit to go
GPRS online.
Maximum data storage available is 2,600-20,000(depending on model) data strings. If storage capacity exceeds, first stored
points will be overwritten.

Geo Fence
Geo fence is very much like a virtual fence and has variety of uses. Multiple Geo fences (up to 5) can be set on the device.
Whenever device crosses the Geofence boundary, it will raise alert.
In this section we will implement the Geo Fence feature on the unit.
GEOPOLY –Polygonal Geo fence
Format
%GEOPOLY,Number,Type,nPoints,Lat1,Lon1;...(next coordinates) ..;ID
%GEOPOLY
Setup Polygonal Geofence.
(Max. 20point)
Number
Number of geo fence. It start from 1.
Trigger type
0 = Trigger when inside, 1 = Trigger when outside, 3 = Disable.
nPoints
Number of points geofence consists of.
Lat1
Latitude of 1st point
Long1
Longitude of 1st point.
ID (Optional)
ID is any number ID assigned to the geofence. This can be used to identify geo fence when
retrieving it using “GEO?” command.
Note:
Coordinate pair is separated by semi-colons and cannot exceed 20 points.
Example of 5 vertex

If Geo fence violation occurs, the unit will send GPS data and status to Control Base via GPRS or SMS.
It will also send alert to all the authorized contact numbers set in device.
