2. INTRODUCTION
2.1 GENERAL
The Nokia 12 GSM Module provides wireless connectivity and remote
management possibilities for machine-to-machine (M2M) applications and other
wireless solutions. The Nokia 12 GSM Module has two variants:
• RX-2 is dual band EGSM900/GSM1800 product
• RX-9 dual band GSM850/GSM1900 product.
The Nokia 12 GSM Module supports EGPRS, GPRS, HSCSD (not supported in
RX-9), CSD, and SMS.
Simple I/O applications can be easily implemented using the Nokia 12 GSM
Module in the Remote I/O control, which offers message personalising, secure
messaging, and timing functionality for SMS controlled I/O applications.
Additional intelligence for I/O applications can easily be implemented with Java.
Java technology enables upgrading the application software, IMlet, also
remotely.
The Nokia 12 GSM Module enables also location service in the Remote I/O
control. Location coordinates can be easily queried by SMS.
The Remote I/O control is explained in this document.
Note: Some services described or mentioned in this document, such as GPRS, are
network dependent. Please contact your network service provider for details.
2.2 REMOTE I/O CONTROL
In the Remote I/O control the Nokia 12 GSM Module is controlled with, for
example, a compatible mobile phone. Control messages are sent as text
messages from the mobile phone to the Nokia 12 GSM Module. Based on the
information in the text message, the Nokia 12 GSM Module in turn controls a
device or machine attached to it through the M2M system connector.
Table 1. Functions in the Remote I/O control
Function Details
Control a device Switch devices on or off
Switch devices on or off for a period of time

Personalize Define your own device commands (aliases)
Disable acknowledgements for device commands
Select the frequency of alarm messages (alarm once/continuously)
Identify the calling party and give permissions for device control
Position Get position information through the Nokia 12 GSM Module when connected to a
GPS device
The Nokia 12 GSM Module processes the control message it receives, and
sends the response as a text message back to the originator. Received and
recognised control messages are not stored in the Nokia 12 GSM Module
memory. If a text message is not recognised as a control message, it is stored
on the SIM card or Nokia 12 GSM Module memory as a normal text message.
Before you can send control messages to the Nokia 12 GSM Module in order to
control or monitor the device attached to it, you must configure the Nokia 12
GSM Module. Use the Nokia 12 Configurator software, which can be
downloaded at http://www.forum.nokia.com or
http://www.americas.forum.Nokia.com. Some configurations are also possible
with control messages; others require that Configurator is used.
Note: To use Configurator, you need the Nokia 12 GSM Module and a test board.
The Nokia 12 GSM Module is connected to a compatible PC and Configurator with
the test board. A power supply, data cable, antenna adapter, antenna, and SIM
card are also needed. All these items are included in the Nokia 12 GSM Module
test board sales package.
Attach the device to be controlled or monitored with control messages to the
general-purpose inputs and outputs of the M2M system connector of the Nokia
12 GSM Module. There are 11 inputs of which the first three (1-3) are analog
and the rest (4-11) are digital. The Nokia 12 GSM Module has also 9 digital
output pins on the M2M system connector. If the information available from the
device is continuous, select one of the three analog input pins. If the information
is on/off information, use the inputs 4-11. The nine outputs can be used in
digital mode only (set something on/off).

3. SECURITY
There are different levels of access control for the Remote I/O control: message
identifier, password, and authorised numbers. Also the aliases defined for
commands increase security.
You must use a message identifier, which means that you must name the Nokia
12 GSM Module to be able to use the Remote I/O control. Each control
message begins with an identifier, which enables the Nokia 12 GSM Module
recognise it as a Remote I/O control message. Enter the identifier with the
Nokia 12 Configurator software when using the Nokia 12 GSM Module for the
first time (see chapter 4.5). Only users who know the correct message identifier
can control and monitor the device attached to the Nokia 12 GSM Module. The
message identifier is case sensitive.
You can use a password to further secure the communication between the
mobile phone and the Nokia 12 GSM Module. You must enter the password
when sending a control message to the Nokia 12 GSM Module. Set the
password with Configurator or with a control message (see chapter 5.2). Only
users who know the correct password can control and monitor the device
attached to the Nokia 12 GSM Module. The password is case sensitive.
You can also determine a closed user group of up to 16 authorised phone
numbers. The Nokia 12 GSM Module only accepts control messages from
these phone numbers. Specify the numbers with Configurator. The first number
on the authorised phone number list is in bold and it identifies the main user of
the Nokia 12 GSM Module. The main user is notified of any unauthorised
control attempts.
You can use user-defined commands (aliases) instead of the default
commands of the Nokia 12 GSM Module (see chapter 5.3). If an alias has been
defined, the default command can no longer be used and is not accepted as
part of a control message. While default commands are generally known, an
alias is only known by the one who defined it. Only users who know the correct
alias can control and monitor the device attached to the Nokia 12 GSM Module.
Note: The message identifier and password are case sensitive, whereas
commands and aliases are not.

GSM Module through the M2M system interface. The general-purpose inputs
and outputs of the M2M system connector that are described in Chapter 6 are
connected to the device.
More information about how to connect a device electrically to the Nokia 12
GSM Module and about the recommended connector types is provided in Nokia
12 GSM Module HW Integration Manual.
4.3 MANDATORY SETTINGS
To use the Remote I/O control of the Nokia 12 GSM Module, you have to
configure these settings:
• Message identifier
• SMS centre address
• You can also configure the following optional settings (described in Chapter
5):
• Disabling acknowledgements
• Security settings
• Input settings
• Defining aliases for text messages
• Initial output value settings
• GPS port settings
Use Nokia 12 Configurator to configure the settings of the Nokia 12 GSM
Module. Download Configurator at http://www.forum.nokia.com or
http://www.americas.forum.nokia.com. You can also use a control message
(short message) for the optional settings.
The following sections describe the process of getting started with the Remote
I/O control.
Note: To use Configurator, you need the Nokia 12 GSM Module and a test board.
The Nokia 12 GSM Module is connected to a compatible PC and Configurator with
the test board. A power supply, data cable, antenna adapter, antenna, and SIM
card are also needed. All these items are included in the Nokia 12 GSM Module
test board sales package.
8/49
4.4 READING AND WRITING PARAMETERS
To read parameter values from the Nokia 12 GSM Module and write parameter
values to it, use Configurator. Each Configurator dialog has “Read parameters”
and “Write parameters” button for this purpose. Data is transferred between
Configurator and the Nokia 12 GSM Module only after you have clicked either
of these buttons.
Note: To apply the configured settings, click either the Read parameters or Write
parameters button.
Some of the settings require that you reset the Nokia 12 GSM Module before
they take effect. Either click the Reset button on the test board or remove and
plug in the power cord on the test board. You can also use Configurator to reset
the Nokia 12 GSM Module (File -> Reboot Module).
Note: The Nokia 12 GSM Module should be reset after you have configured all
parameter values.
After a parameter value has been successfully configured to the Nokia 12 GSM
Module, the dialog in Figure 1 appears.
Figure 1. Dialog for successful parameter configuration
4.5 DEFINING THE MESSAGE IDENTIFIER
The message identifier is a mandatory setting that must be configured in order
to use the Remote I/O control. Figure 2 shows a dialog (User Control Mode ->
Settings -> Initialize) where you can set the identifier in Configurator. To define
the message identifier, press Change. See Figure 2.
Note: Press the Write parameters button to activate the new identifier.
After you have set the message identifier, more parameters become available.
If a message identifier has been previously defined to the Nokia 12 GSM
Module, press the Read parameters button to enable the additional parameters.
9/49
Characters accepted for the message identifier are defined in Chapter 7, except
the space characters.
Note: You cannot use the Remote I/O control if there is no message identifier
defined. In this case, all received short messages will be handled as normal
messages and the inputs/outputs cannot be controlled in the Remote I/O control.
Note: The message identifier is 1-8 characters long and case sensitive.
Figure 2. User Control Mode dialog
10/49
4.6 SETTING THE SMS CENTRE ADDRESS
A dialog for setting the SMS centre address with the Nokia 12 Configurator
(GSM Settings -> Advanced -> Short Messages) is shown in Figure 3.
To check whether the SMS centre address is available on the network service
provider SIM card, press the Read parameters button shown in Figure 3. If the
SMS centre address is not available, specify it in the Short Messages dialog in
order to be able to use the Remote I/O control.
Note: Contact your network service provider for the SMS centre address.
Figure 3. Short Messages dialog
Short messages can be stored in the SIM card or the Nokia 12 GSM Module
memory. If both of these short message storages are full, new messages
cannot reach the Nokia 12 GSM Module. If the “Remove oldest message”
option is selected in the short message dialog, the oldest message will be
removed from the SIM card memory when a new message arrives, if both the
11/49
SIM card and the Nokia 12 GSM Module memory are full. It is recommended to
select the option “Remove oldest message when new arrives” for the Remote
I/O control, because then the control messages have a better chance of
reaching their destination and fulfilling their purpose.
12/49
5. OPTIONAL CONFIGURATIONS
5.1 DISABLING ACKNOWLEDGEMENTS
The Nokia 12 GSM Module acknowledges whether or not a text message has
successfully commanded a device. The Nokia 12 GSM Module sends a
response as a text message back to the phone number that sent the control
message. It is also possible to disable this feature to decrease the amount of
communication with the device, for example.
Figure 4 displays a dialog (User Control Mode -> Settings -> General) for
configuring acknowledgement messages.
13/49
Figure 4. General settings
If you select the Disable acknowledgements option, only response messages to
acknowledgement messages are disabled. The following will not be disabled:
• Status messages; responses to input state or value queries
• Indication messages, for example, responses to timed commands (see
Chapter 9.3.7)
• Alarm messages; responses to alarm subscriptions (see Chapters 5.4 and
9.3.3)
• Error messages that are sent, for example, in response to a control
message with the correct message identifier and password, but with the
wrong command
14/49
• Response messages to password change messages (see Chapter 9.3.1)
• Response messages to pulse cancel messages (see Chapter 9.3.8)
5.2 SECURITY SETTINGS
Figure 5 shows a dialog (User Control Mode -> Settings -> Security) where
security settings can be configured with Nokia 12 Configurator.
5.2.1 Authorised numbers
Authorised number selection limits the access to specific phone numbers only
in the Remote I/O control. Only control messages originating from an
authorised number are allowed to control the Nokia 12 GSM Module and the
device attached to it.
It is possible to define up to 16 authorised numbers. The first number on the
authorised phone number list is in bold (see Figure 5) and is the phone number
of the main user. The main user will be notified of any unauthorised control
attempts.
The following message will be sent to the main user if there is an unauthorised
control attempt:
Unauthorized Number:
Number: X
Command: Y
X is the phone number of the originator of the control message, and Y is the
command that was attempted. If the length of a command or alias is too long to
be shown in one message (more than 160 characters), it will be sent as several
messages.
The phone numbers in the authorised number list may contain digits 0-9 and
the “+” character (ASCII range 0x30-0x39 and 0x2B), for example,
+1234567890, for a maximum length of 32 characters.
Note: The phone numbers in the authorised number list should be defined in
international format with a plus sign, country codes, etc. Note that the Nokia 12
GSM Module needs to receive and identify the number to recognise it as
authorised. Contact your network service provider for details.
15/49
Figure 5. Security settings
Authentication
A user-specified password can further secure the communication between a
mobile handset and the Nokia 12 GSM Module. The password must be entered
when a control message is sent to the Nokia 12 GSM Module. When this
feature has been set on, but the password is missing or incorrect, the message
received is discarded. Activate or change the password with Configurator or
with a control message (see Chapter 9.3.1).
16/49
The length of the password is 1- 8 characters, and it is case sensitive. It
accepts characters defined in Chapter 7, except space characters. The
password is case sensitive.
Note: If the password is changed, an indication message is only sent to the phone
number that requested the change.
5.3 ALIASING
Figure 6 shows a dialog (User Control Mode -> Settings -> Aliasing) where
aliases can be defined for commands with the Nokia 12 Configurator.
17/49
Figure 6. Setting aliases for device commands
In the Aliasing dialog, you can replace the predefined commands with user-
specified commands (aliases). The defined alias replaces the initial command
or previous alias configured for the command. If an alias has been configured,
the original command is no longer accepted. Defining an empty alias for a
command can restore the original command. Duplicate aliases are not allowed.
Aliases can also be defined for status messages sent in response to status
queries. Thus, an alias can be defined for a command for controlling the device,
querying the status of the device (see chapter 9.1), and for the message
received in response to the query (see chapter 9.2).
18/49
Characters accepted in aliases are defined in chapter 7.
Note: If an alias is defined, the default command will be disabled. There can be
only one effective command or alias for each function at a time. An alias must not
be equal to a default command.
Empty aliases cannot be used. If an empty alias is set, the default command will
remain effective.
Note: The alias string must be unique and the maximum length is 24 characters.
Neither commands nor aliases are case sensitive. However, the message identifier
and password are.
5.4 INPUT SETTINGS
Figure 7 shows a dialog (File -> Module Configuration -> Input Settings) where
you can configure analog input settings with Configurator.
The Nokia 12 GSM Module has separate digital and analog inputs. You can set
high and low limits to the analog input pins. The pin can be in the normal or
alarm mode. If the information is continuous, use inputs 1-3.
The input sampling interval indicates the period for which the Nokia 12 GSM
Module polls the input state. The sampling interval value ranges from 1 to 60
seconds.
For control messages querying input states or values, see Chapter 9.3.2.
You can subscribe to text message alarms as response messages. This is
done using control messages described in Chapter 9.3.3.
As a default, the alarm message is sent once to the number where the alarm
was subscribed. Alternatively, the alarm can be sent continuously. In this case,
alarm messages are sent when alarm conditions are met, until the alarm
subscription is cancelled (see Chapter 9.3.3). To configure the alarm sequence,
select “Continuously” or “Once” in the Input Settings dialog.
In analog input, or if device data is continuous, an alarm can be set to be
triggered when a limit is crossed. Configurator requires the high and low limits
as millivolts (0 … 2800 mV) and the sampling interval as seconds (1-60 s).
Control messages for subscribing an alarm or alarms are described in chapter
9.3.3.
Note: It is mandatory to set input high and low limit values in the analog mode.
Note: The number to which alarm messages are sent can only be defined by
subscribing to an alarm. After the subscription, the alarm will be sent as a response
to the number where the alarm was subscribed. Thus, the number cannot be
defined with Configurator.
19/49
Note: In digital input, an alarm can be triggered when the state of the digital input
changes. See chapter 9.3.3 for more information.
Figure 7. Input settings
Note: In Figure 7 the Input 1 and 3 cannot be used for alarming because they are
configured as Normal.
5.5 DEFAULT OUTPUT VALUE SETTING
Set the initial state of each output pin and the device being controlled with
Configurator (File -> Module Configuration -> Default Output Values). The
20/49
values set here will take effect the next time the Nokia 12 GSM Module is
powered up.
Check the box in the Default Output Settings window to set the output to 1. If
you leave the box empty, the output is 0.
Note: The number of available digital outputs depends on the port configurations.

7. SUPPORTED CHARACTERS
The characters listed in Table 4 are supported for:
• Message identifier
• Password
• Aliasing
The list is derived from the Default Alphabet table of a GSM technical
specification (see Digital cellular telecommunications system (Phase 2+);
Alphabets and language-specific information (GSM 03.38)). CR, LF and Escape
characters are not supported.
Note: You cannot use a space in the message identifier or password. However,
you can use it in aliases defined for commands.

8. COMMAND SYNTAX
The command syntax of control messages varies according to the activated
options. There may also be spaces in aliases defined for commands as seen in
the example below. However, only one space character is accepted between
words. The message identifier and password are case sensitive.
Note: A control message always begins with a message identifier. Otherwise the
message is not interpreted as a Remote I/O control message, and is stored in the
SIM card or the Nokia 12 GSM Module memory.
Control message without a password:
<message identifier> <command / alias>
term123 Output_Set All On
Control message without a password with an alias defined:
<message identifier> <command / alias> <parameter>
term123 Output_Pulse All On 1h30m
Control message with a password:

term123 password Output_Set All On
Control message with a password with an alias defined:
<message identifier> <password> <command / alias>
<parameter>
term123 password Output_Pulse All On 1h30m
26/49
9. REMOTE I/O CONTROL SMS COMMANDS
The following chapter describes the commands and status messages available
in the Remote I/O control. Status messages are sent in response to device
status queries. You can define an alias for each of the commands and status
messages described here with Configurator.
The first part of the chapter lists commands that are sent to the Remote I/O
control as part of a control message; the second part provides a list of status
messages for which an alias can be defined.
9.1 COMMANDS
The Nokia 12 GSM Module supports the SMS commands listed in Table 4.
These commands are for controlling or monitoring purposes (to query the state
of a device attached to the Nokia 12 GSM Module). An alias can be defined for
each of the commands.
Note: If an alias is defined, the default command will be disabled. There can be
only one effective command or alias for each function at a time. An alias must not
be equal to a default command.
Empty aliases cannot be used. If an empty alias is set, the default command will
remain effective.
Note: The alias string must be unique and the maximum length is 24 characters.
Neither commands nor aliases are case sensitive. However, the message identifier
and password are.

9.2 STATUS MESSAGES
The Nokia 12 GSM Module supports the status messages listed in
Table 5. You can define an alias for each of them. The messages will be sent
as responses to device query control messages according to the current
command and device state.
28/49
Note: If an alias is defined, the default command will be disabled. There can be
only one effective command or alias for each function at a time. An alias must not
be equal to a default command.
Empty aliases cannot be used. If an empty alias is set, the default command will
remain effective.
Note: The alias string must be unique and the maximum length is 24 characters.
Neither commands nor aliases are case sensitive. However, the message identifier
and password are.

9.3 DETAILED COMMAND INFORMATION AND RESPONSES
All example commands in this chapter use the “term123” identifier string, and
the password property is set off in all of the subsequent chapters.
Note: If a command or the alias defined for it is not identified, but the identifier and
the optional password are correct, the Nokia 12 GSM Module will send an error
message as a response to the command originator, for example:
Control message: term123 passWORD ResetAll
Response: ERROR (Unknown Command)
9.3.1 Changing the Password
Use the Change_Pword command to control the password. Note that all
example commands in this chapter use the “term123” identifier string (see
Table 6).

9.3.2 Reading Inputs
Use the Input_Get X commands for reading inputs, that is the state or value of
a device. Note that all example control messages in this chapter use the
“term123” identifier string and the password property is set off (see Table 7)
A response depends on the pin. There are three analog inputs (1-3) and nine
digital inputs (4-11) in the Nokia 12 GSM Module M2M system interface. You
can also specify an alias for the response (see chapter 9.2).

31/49
9.3.3 Subscribing to Input Alarms
To subscribe to input state changes, that is, alarms, use the
Input_Get_Change X commands. All example control messages in this
chapter use the “term123” identifier string and the password property is set off
(see Table 9).
When you subscribe to this service, and an input state changes, you will
receive an alarm message. You can also subscribe to alarms on a continuous
basis, so that each time the state changes, you receive an alarm message until
you cancel the subscription with the Input_Change_Cancel command.
You can subscribe to alarms for all input state changes at once, or to each input
separately. Note that an input must be configured properly in order to get the
alarms. For more information about alarm configurations, see Chapter 5.4.
There are two ways to configure an analog input to operate with alarm sending
(see Chapter 5.4 for configurations):
• Alarming + Input High Limit + Input Low Limit + Sampling Interval
• Once/Continuously
An alarm from the analog pin is sent if the value is equal to or higher than the
high limit, or equal to or lower than the low limit. Define the frequency of the
state of the input polling in the sampling interval box (see Figure 7).
An alarm from the digital pin is sent if the digital pin state is changed and the
input state change is subscribed to that pin by the Input_Get_Change X
command.
Important: The latest subscription overrides any previous alarm subscription. The
alarm will only be sent as a response to the latest subscription; the originator of the
previous subscription will not be notified.

9.3.7 Output Pulses
Use the Output_Pulse X Y commands to set digital output states to
requested state for a specified time. Note that all example control messages in
this chapter use the “term123” identifier string and the password property is
set off (see Table 12).
While the pulse is active, the pin state remains as requested and is locked. You
can cancel the pulse with the Output_Pulse_Cancel command described in
Chapter 9.3.8. After the requested time has passed, the output state is returned
to the opposite value of that requested. The final state of the output is
independent of the initial state of the output.
The behavior of the output pins when the Output_pulse X command is used
is depicted in Figure 9.

9.3.8 Cancelling Output Pulses
It is possible to cancel pulses before the <time> parameter defined in the pulse
control message has passed. This is done with the “Output_Pulse_Cancel
40/49
X” command. Note that all example control messages in this chapter use the
“term123” identifier string and the password property is set off (see Table 13).
The command cancels the timing of the pulse operation and informs the original
pulse originator about it. The state of the cancelled output remains the same, as
was set with Output_Pulse X command. Thus, it is the timing of the pulse
that is cancelled, not the pulse itself.
