Supported are 4.1 • incomming and outgoing GSM data connections with 9600 bps with modems being connected to the GSM network, the ISDN or the analogue telephone network, • sending of SMS (Short Message Service). Terminal mode activation Terminal mode is the factory default setting The SINAUT MD720-3 supports two fundamental operation modes: • Terminal Mode, • OPC Mode. The SINAUT MD720-3 is delivered by the factory with activated Terminal Mode. Switching from OPC Mode into the Terminal Mode If it is necessary to switch a manually the SINAUT MD720-3 from OPC Mode into the Terminal Mode, you will find the instructions for this in the chapter Switching between Terminal mode and OPC Mode on page 59. SINAUT MD720-3 C79000-G8976-C211 25 SINAUT MD720-3 in Terminal Mode 4.2 Operating requirements: GPRS subscriber contract To use the SINAUT MD720-3 in Terminal Mode it is required: 4.3 • SIM card of a GSM network operator including CSD data service 9600 Bit/s and a telephone number for data calls, • Availability of a GSM network. Functions of the LEDs in Terminal Mode The device has 3 LEDs, which indicates the current operation status: S (Status) Q (Quality) LED S, Q, C combined S (Status) Q (Quality) C (Connect) C (Connect) Status Meaning Fast lighting in sequence Boot procedure Synchronous slow blinking Service mode Slow lighting in sequence Update Synchronous fast blinking Error Blinks slowly Device waiting for PIN input Blinks fast PIN error / SIM error Blinks slowly Booking into GSM network 1x intermittent blinking Field strength not sufficient 2x intermittent blinking Field strength sufficient 3x intermittent blinking Field strength medium ON permanently Field strength high OFF Waiting for PIN input Blinks Terminal mode active Blinks slowly: 1 x per second Blinks fast : 4 x per second 26 SINAUT MD720-3 C79000-G8976-C211 SINAUT MD720-3 in Terminal Mode 4.4 Terminal mode operation To operate the device the PIN (PIN = Personel Identification Number) of the inserted SIM card must be known. In the Terminal Mode the PIN is not stored in the SINAUT MD720-3. The PIN must be set again everytime the device is turnedon. ● The PIN is set by AT commands. Control by the application Usually the application or the application software, which you execute on a connected computer, will control the SINAUT MD720-3. So wit, the commands to establish or to disconnect a data connection via the GSM network, are given by the application to the device. For this purpose the application and the device communicates using AT commands, like other types of modems. The sending of SMS is handled in the same way. Direct control using AT command You can also enter manually AT commands to control the SINAUT MD720-3. In this case use any terminal program (Refer to Working with a terminal program, page 28.) Or you write your own communication program which is adapted specially to your purposes. Enter the PIN first Please enter the PIN first before any other AT commands. Until a PIN has been entered most AT commands will be answered with ERROR. SINAUT MD720-3 C79000-G8976-C211 27 SINAUT MD720-3 in Terminal Mode 4.5 Entering AT commands The SINAUT MD720-3 is controlled by AT commands, which are entered either by the connected application or manualley bya terminal program. Working with a terminal program To be able to control the device directly via AT commands, use a terminal program, e.g. HyperTerminal. Note the following settings: Make the connection: COM port to which the device is connected Speed: 9600 Bit/s Data bits: Parity: No Stop bits: Duplex: Full PIN in Terminal-Mode Enter the PIN If the LED S blinks slowly (1 time per second), the SINAUT MD720-3 waits for a PIN entry. In Terminal-Mode the PIN need to be entered using the AT command AT+CPIN. Example: Command: at+cpin="0000“ Response: OK The number of permitted trial to enter the PIN is limited by the SIM card. Normally three attempts are allowed, i.e. you may enter two times back-to-back a wrong PIN, at the third attempt the right PIN must be entered, otherwise the SIM will be blocked. In this case the SIM card can only be unblocked by entering the PUK. 28 SINAUT MD720-3 C79000-G8976-C211 SINAUT MD720-3 in Terminal Mode The LED S (status) blinks fast If the modem blinks fast (4 times per second), either the SIM card was not detected correctly or the SIM card is PUK-blocked, because a wrong PIN has been entered too often. Please check, if the SIM card is inserted correctly (see chapter 2 Inserting the SIM card). Please check, if the SIM card is PUK-blocked. Insert the SIM card into a common mobile phone. The mobile phone will display, if the SIM card is PUK-blocked. If the SIM card is PUK-blocked, please enter the PUK and then a PIN. You can use a common mobile phone to do this. Before you enter again the SIM card into the SINAUT MD720-3, please investigate why the SIM card has been PUK-blocked: Which PIN have you entered or which PIN has your application sent to the SINAUT MD720-3? Changing the SIM card If you change the SIM card, please do not forget to update also the PIN number in your application. If you use a lot of SIM cards it can be helpful to set all PINs to the same PIN number. You can do this i.e. by using a mobile phone. Please observe the security requirements of your organization. PIN-less SIM cards The device operates also with SIM cards, which PIN check is deactivated. In this case the PIN check is skipped and the device will immediately try to attach the GSM network. SINAUT MD720-3 C79000-G8976-C211 29 SINAUT MD720-3 in Terminal Mode 4.6 Use AT commands Syntax The AT command language is a standard for controlling modems. It is lineorientated. Each command line begins with AT (for ATtention), followed by the actual command, and ends with (Enter key). Example: ATD444444¬ means: dial (D for Dial) 444444 There are only two exceptions to this rule: The command +++ to switch to Command Phase (see below) and the command A/ with which the last command line is repeated. Command phase, Transparent phase The device accepts AT commands only when it is in Command Phase. It is in Command Phase, • when there is no active connection, • when the sequence Pause +++ has been entered during a connection. The device does not accept AT commands when it is in Transparent Phase. It is in Transparent Phase, • when there is an active connection, • when the device has been switched to Command Mode during an active connection with +++ and then switched back to Transparent Mode with ATO. Enabling/disabling local echo To see your entries on the screen, you may have to enable the local data echo. To do so, enter the following command: ATE1 To disable the local data echo, enter the following command: ATE0 30 SINAUT MD720-3 C79000-G8976-C211 SINAUT MD720-3 in Terminal Mode Enter the PIN Command: at+cpin="0000“ Response: OK Network-Status request Command: at+creg?
