3. Functi onal diagr am and operati on descri ptio n

3.1. Functional diagram

The functional diagram of the modem is displayed on Fig. 3.1.1.

Fig. 3.1.1. Functional diagram of the modem

3.2. Operation description

The operation mode of the modem changes depending on the presence of the SIM-tray. When the SIM-tray is install ed, the modem is i n the operat ion mode m eaning that the pi ns of the RS485 i nterf ace of t he umbilical connector are wired t o t he UART 0 of t he GSM m odul e, UART of the managi ng micr ocont roll er is connec ted to the UART1 of the GSM module, and the GSM module is tuned on.

In case the SIM- tray is mi ssing the m odem i s either in the progr ammi ng mode (the SIM- tray was removed before powering the modem) or the menu mode (the SIM-tray was removed after powering the modem). In both cases the GSM m odem is turned of f (t he modem’s power is shut down), and the RS4 85 int erface pins of the umbilical connector are wired to the UART of the managing microcontroller.

The programmi ng mode allows updating t he software of the m anaging microcontroller. T he menu mode allows changing the m odem’s parameters and access the statistics.

Page 13

The modem can be powered using either of the two connectors: the power connector or the umbilical connector.

3.3. Watchdog timer types

Several types of watchdog timers are provided in the GSM modem:

Built-in watchdog tim er in the managi ng microcontroller. The m icrocontroller it self is m onitored for a

possibility of software crash (It is permanent ly on and cannot be turned off);

A regul ar check by t he m anaging microcontroller for a possibility of the GSM module deadlock of the

Java-appli cation. The interval can be set by the u ser in the range f rom 1 to 255 mi nutes in 1 minut e increments. T he principle of i ts operation im plies that the managi ng microcont roller periodically sends the “at” command ( speed 115200b/s, 8-N-1) to t he second COM-port of the module and wai ts for a response “at”, then “OK”. Also, after each command, there should be “\r=CR \n=LF”. The response should be analogou s to the response of the module wit hout the Java-appli cation wit h enabled echo. If no response is received t he GSM module reboot s. The m odule’s power in t he meantim e is shut do wn. This function can be activated or deactivated in the menu mode. This function is switched off by default;

Note: Java-applicati on can occupy this COM -port, which will result in constant reloadi ng of the module

(where the function is activated).

An unconditional reboot of the modem after a period of t im e set by user. This function is switched off by

default. The per iod of tim e can be set bet ween 1 and 255 hour s in 1 hour i ncrem ents. The princ iple of its operation implies that the managing microcontroller after a set period of time reboots the GSM module and the m odule’s power is shut down. The control of this functi on is done in the menu m ode (see Part 4.3).

Page 14

4. Conne cting and configur ing

4.1. Connecting

Only indivi duals with speciali zed technical training and who hav e studied the product specifi cations are permitted to assem ble (install) the modem.

Insert t he SIM- card t ray into the modem. Be careful when installing the SIM-card. Connect the GSM antenna and the commuting USB or RS232 cabl e. The modem can be powered using

the USB cable. If needed the modem can be powered using the TJ6-6P6C power connector (see Fig. 2.5.2).

Note: GSM antenna, the commuting cables and the power supply are not included in the set.

4.2. Control, rebooting and connecting

The modem is contr oll ed using standard A T -commands. You can fi nd addit i onal i nformation and supp ort at

www.irz.net.

The modem can be rebooted using one of the following ways:

Rebooting after a given period of time (WD interval, turned off by default), setting is done in the menu

mode; By AT-command “AT+CFUN=1,1”; Temporary power shutdown.

The modem can be shut down using one of the following ways:

Program method using AT-commands only in case transition to sleep m ode is allowed; Power shutdown.

When modem is disabled by using AT-c ommands, you can u se the al arm f unction (ALARM m ode) to run

modem.

Switch-over of m odem i nto power saving mode by using AT -c omm and "AT+CFUN". Cont rolli ng t he alarm

mode by using AT-command “AT+CALA”. For more detail see AT-commands description for the GSM module.

Page 15

4.3. Menu mode

The menu mode’s f unction i s to change the m odem’s param eters and access the statisti cs. In thi s mode, the power of the GSM module is switched off. After leaving the menu mode automatic rebooting takes place. To access the menu mode from the operation mode remove the SIM-tray. Before accessing the menu mode connect the modem to the computer through the DB9 connector. Run Hyper Terminal or a similar program.

Remove the SIM-tray (by pressing the SIM-tray ejector button). The modem will go into the menu mode:

Menu mode:

Power_Module = XX…X

Bad_Power_Module = XX…X

Start_Module = XX…X

Bad_Start_Module = XX…X

Deadlock_of_Module = XX…X

Reset = XX…X

The modem automatically stores the number of the following situations:

Power_Modem – t he number of times the modem has been turned on;

Bad_Power_Mod em – the number of times the modem power has deviated from the allowed;

Power_Module – the number of times the power of the GSM module has been turned on;

Bad_Power_Module – the number of times the GSM module power has deviated from the allowed;

Start_Module – the number of the successful launches of the GSM module;

Bad_Start_Module – the number of situations when the GSM module failed to launch;

ComPort_is_not_Running – the number of situations when the COM- port of t he module is not ready (t he

CTS signal is being analyzed);

Page 16

Deadlock_of_Module – the number of GSM module deadlocks;

Reset – the number of resets.

After the statistics appears the transition to the main menu occurs.

Use <P2> command to proceed to the WD submenu:

WD interval, hour (0 - WD off, max - 255)

5. Creating, installing and deleting of Java-applications

This modem based on module Cinterion TC65i with built-in Java platform, which allows for many tasks. You can create, i nstall and del ete Java-applicati ons with speci al tool s from Cinteri on company, “Module Exchange Suite” (MES) application. The software is avail able at www.irz.net, or from delivering on CD/DVD from our managers.

After «Module Exchange Suite» is installed, in the root directory shall be added the drive “Module”:

Fig. 4.4.1. My Computer window of Windows XP

In disk properti es (Port tab) select COM-port, which connected with the modem:

Fig. 4.4.2. Select COM-port

Page 22

Fig. 4.4.3. Working with “Module” Disk

Working with “Modul e Exchange Suit e” is t o copy and delet e needed fi l es to disk “Modul e”. F or exampl e, to install the Java-based applications simply copy the files to disk “ Module”.

Autostart of Java-based applications is given by the following AT-commands:

AT ^SCFG="userware/autostart/ appname","","a:/ ХХХ.jar" (where ХХХ is f ile name); AT^SCFG="userware/autostart/ delay", "","100" (autostart after 10 seconds after modul e is turned on); AT^SCF G="userware/autostart","","1" (aut ostart is enabl e).

For startup is recomm ended to set t he interv al of about 10 seconds. T his is especi ally im portant when you testing the new Jav a-based applications. T his further simplifies the process of abolishing the autostart. After the startup of Java-based application, port may not respond to AT-commands.

To remove Java-based applications, you need to cancel autostart. This can be done by AT-command AT^SCFG="userware/autostart","","0" if it was set i n adv ance suff icient i nterval of autostart . You must sent this AT-command should be after 2-5 seconds after t he power t o the modem. After a successful attempt to sent AT-command, the modem must answer “OK”.

Page 23

Fig. 4.4.4. General view of «AutoExec» application

If the specifi ed aut ostart i nterv al does not al l ow send AT -comm and t o cancel autostart , i n this case u se the program “autoexec_off.exe” (att ached to the development software). Sequence of actions shall be as f ollows:

connect the modem to the computer, run «autoexec_off.exe», and at the program window, enter t he number of CO M-port, power on the modem and af ter 1-3 seconds click on «AutoExec Off » button (need to get in the time

interval bet ween the start of the module and the launch of Java-based application).

If autorun is turned off, then message should appear: “AutoExec successfully switched off”.
