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.

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
http://www.americas.forum.Nokia.com
or
. 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.

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.

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.
