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.

Note:
In AUTOARM mode NTT will automatically Arm itself when the IGN is off and Input -3 is active. It will DisArm itself when Input-3 is
inactive.
Input-3 must be connected to the vehicle’s central locking signal which is going to doors. This provides very high security for the
vehicle as the Engine will be killed when drivers locks the vehicle.
In this mode if any intruder somehow opens the door, Alarm will be generated. He will not be able to start the vehicle and if he
tries to tow the vehicle, alarm will be generated.
