1. DOCUMENT SCOPE
This document describes how the Nokia 30 GSM Connectivity Terminal can be used in User
control mode. The ways of controlling the terminal in this operation mode is described as well
as how this can be done in a more secure way.
For more detailed information about the Nokia 30 GSM Connectivity Terminal, other Nokia
M2M products and application development for M2M, please visit Forum Nokia and M2M
links at http://www.forum.nokia.com
.
2. PRODUCT CONCEPT AND USAGE
2.1 GENERAL
Nokia 30 is a GSM Connectivity Terminal for EGSM 900/GSM 1800 networks. It includes a
GSM transceiver with built-in data capabilities, a SIM card reader, an internal antenna, an
external antenna connector, and an M2M system connector.
The Nokia 30 GSM Connectivity Terminal has three different operation modes:
§ User control mode
§ AT command mode and
§ M2M system mode
In AT command mode the Nokia 30 GSM Connectivity Terminal is used as a GSM data
modem using AT commands. In M2M system mode the Nokia 30 is used as a part of Nokia
M2M Platform using CORBA messaging.
2.2 USER CONTROL MODE
In the user control mode the Nokia 30 GSM Connectivity Terminal is controlled with e.g. a
mobile handset. Text message (short message service = SM) templates that are sent from
the mobile to the Nokia 30 instruct the terminal, which in turn controls a device or machine,
attached to it through the M2M system connector.
3/18
The Nokia 30 processes the SM and sends a response back to the command originator.
Finally, a received and recognized command will be deleted by the service. Unrecognised
commands would be stored to terminal or SIM as normal messages.
The control or monitoring is through general-purpose inputs and outputs of the M2M System
Connector. Thus, there are three general-purpose inputs and five general-purpose outputs
on the M2M system connector of the Nokia 30 GSM Connectivity Terminal. The inputs can
be used in either digital (on/off) or analog (continuous signal) mode. The outputs can be used
in digital mode only (set something on/off).
3. SECURITY
There are three levels of access control for User control mode: message identifier, password
and authorization number. A message identifier has to be used i.e. the terminal has to be
named in order to be able to use the User control mode of the Nokia 30 GSM Connectivity
Terminal. The identifier initiates every text message template aimed to control the Nokia 30
GSM Connectivity Terminal and the application attached to it.
The identifier is entered with the Nokia 30 Configurator software when the terminal is used
for the first time.
A user specified password could be used to further secure the communication between the
handset and the terminal. The password is entered whenever a text message template is
sent to the Nokia 30. The password is activated and/or changed with the Nokia 30
Configurator software or a text message (SM).
Access can be secured by specifying from which phone number the requests for control are
allowed, thus determining an authorization number. The number specification is done with
Nokia 30 Configurator software. Only one number can be specified as authorization number.
4/18
4. GETTING STARTED
4.1 SECURITY SETTING
The following settings must be made first before the User Controlled I/O service can be used.
All settings can be made with Nokia 30 Configurator software by opening menu option
Remote I/O Control -> User control mode (see Figure 1).
4.1.1 Message identifier
Message identifier is a mandatory parameter that has to be set in order to use the service. If
this parameter is not set (i.e. its empty), the service is switched off and commands cannot be
executed by the service. The parameter accepts 0-8 characters (ASCII character range
0x20-0x7E) e.g. Nokia30. A command always starts with the Identifier. Note that the Identifier
parameter is case sensitive (see Figure 1).
4.1.2 Authorization number
Authorized Number is an optional parameter that could be used if a user wants to secure the
system e.g. in case commands will be accepted only from one phone number. The most
secure system will be achieved if both, the Authorized Number and the Password, optional
properties are activated. The parameter accepts numbers 0-9 and ‘+’ character (ASCII range
0x30-0x39 and 0x2B) e.g. +1234567890 and the maximum length of it 32 (see Figure 1).
If Authorized Number property is activated and a terminal receives a command from some
other phone number, it will send a following indication message to the Authorized Number:
Invalid Originator:
Number: X
Command: Y
Where X refers to an invalid command originator phone number, and Y refers to a
"command". The command may or may not be a valid command. If a command length is too
long to be shown in one message, the Y refers to a text "Too Long". In this case, the
indication message looks like this (X as described above):
Invalid Originator:
Number: X
Command: Too Long
5/18
4.1.3 Password
Password is an optional parameter that could be used if a user wants to secure system e.g.
in case that commands will be accepted from several phone numbers. The parameter
accepts 0-8 characters (ASCII character range 0x20-0x7E) e.g. password. The password is
case sensitive (see Figure 1).
Figure 1 User Control mode dialog in the Nokia 30 Configurator.
4.2 INPUT MODE AND INITIAL OUTPUT STATE
Input modes and initial output states can be configured with the Nokia 30 Configurator by
opening menu option Remote I/O control -> General.
Each of the inputs can be configured as digital or analog depending on the nature of the
device being monitored. If the information available from the device is on-off information, the
input should be configured as digital. If in turn the information is of a continuous nature, the
input should be analog. (See Figure 4 for a view of the Nokia 30 Configurator for Input
settings).
It is possible to subscribe events as alarms to a specific phone number. In the case of digital
input an alarm can be triggered when the state of the digital input changes. In the case of
analog input low and high limits and a period for checking the input state can be set. For
more information about subscribing input events, see chapter 7.2.3.
6/18
The initial state of each output pin and thus the device being controlled can also be set using
the Nokia 30 Configurator. See Figure 2 for a view of the Nokia 30 Configurator for setting
initial output states.
Figure 2 Setting initial output values with the Nokia 30 Configurator.

4.3 SMS CENTER NUMBER
SMS Centre Number must be set. If it is not set, the service is in off mode. The SMS Centre
number can be set with the Nokia 30 Configurator software by opening menu option GSM
Settings -> Advanced -> Short messages (see Figure 3):
Figure 3 Setting SMS centre number with the Nokia 30 Configurator
Note that it is recommended that the terminal should be switched off and on every time
parameters are changed.
4.4 CONNECTING A DEVICE OR A MACHINE
A device to be controlled with the Use control mode of the Nokia 30 is connected physically
to it through the M2M System Connector. The general-purpose inputs and outputs of the
M2M System Connector described in Chapter 5 are connected to the device.
For more information about how to connect a device electrically to the Nokia 30, please see
reference 3. For information about the mechanical characteristics and recommended
connector types for the M2M System Connector, please see Reference 1.

The command reads
input Z (Z = 1,2 or 3)
and the response
returns the state of it
according to input
pin configuration
7.2.3 Subscribing Input Events
The Input_Get_Change X commands are used for subscribing input state changes (see
Table 5). A subscription will cause a sending of one event per input state change to the
subscriber phone number. The user can subscribe events of all input state changes at once
or each input can be subscribed separately. Note that an input has to be configured properly
in order to get events with this service.
An input can be configured in two ways to operate with event sending:
§ Digital input
§ Analog input + Alarming + Input High Limit + Input Low Limit + Input Period
When the Input mode is set to digital, an event is sent when the state of the digital input
changes from 0 -> 1 or 1 -> 0.
13/18
When the Input mode is set to analog + alarming, an event is sent if the value is equal or
exceeds the high limit or is equal or gets lower than the low limit. The state of the input is
queried in a frequency defined in the period box.
The subscription of events can be used by configuring the correct settings with Nokia 30
Configurator software by selecting menu option Remote I/O Control -> General (see Figure
4).
