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 turned-
on.
● 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.

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: 8
Parity: No
Stop bits: 1
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.
SINAUT MD720-3 in Terminal Mode
SINAUT MD720-3
C79000-G8976-C211 29
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.

4.6 Use AT commands
Syntax
The AT command language is a standard for controlling modems. It is line-
orientated. 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.

5.3 PIN in OPC-Mode
Enter the PIN
If the LED “S” blinks slowly (1 time per second), the SINAUT MD720-3 waits for a
PIN entry.
In OPC-Mode the PIN is sent by the connected PLC to the SINAUT MD720-3.
Therefore you need to enter the PIN in the data module of your SPS program with
reference to the program module WDC_INIT (See System manual SINAUT MICRO
SC). Please check if the PLC and the SINAUT MD720-3 are connected together.
The LED S (Status) blinks fast
If the LED S blinks fast (4 times per second), either the SIM card was not detected
or he SIM card is PUK-blocked, because the a wrong PIN has been entered too
often.
1. Please check, if the SIM card has been inserted correctly into the device (refer
to chapter 2 Inserting the SIM card).
2. 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.
3. 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 into your PLC program?
4. Please check and eventually reset the parameter SIMSTATE of the SINAUT
MD720-3.
Check and reset the parameter SIMSTATE
The parameter SIMSTATE will be displayed when you press the SET button (refer
to 6.2 Getting the current settings and values):
SIMSTATE=SIM_OK Ready for operation
SIMSTATE=SIM_ERROR Wrong PIN; one wrong PIN entry
SIMSTATE=SIM_PROBLEM Wrong PIN; two wrong PIN entries or no SIM
detected
SINAUT MD720-3 in OPC Mode
In case of SIMSTATE=SIM_ERROR or SIMSTATE=SIM_PROBLEM please
proceed as follows:
1. Please make sure, that the correct PIN is entered into the PLC program
module.
2. Push the SET button until the factory default settings has been loaded
(Attention, all settings will be reset)
or
Enter the following AT commands:
AT^PARSTART
AT^PARCSE
AT^PAREND
3. Afterwards the device will perform a restart and is ready of operation again.
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.

GSM
Global System for
Mobile
Communication
Global standard for wireless telephony, data and fax transmission and
transmission of text messages (SMS). GSM based networks are
available in a lot of countries world-wide, with high coverage in Europe,
China, Latin America as wellas in regions of the USA, Africa and
Russia. Depending on the used frequencies you distinguish PCS
850MHz, GSM 900MHz, DCS 1800MHz und PCS 1900MHz networks.
CSD
Circuit Switched Data
GSM Service for wireless data transmission at 9600 bps full duplex.
Connections can be established to other GSM devices, to analogue
modems or to ISDN modems in wired networks. The connections can
be initialized at both sides. Only dial-up connections are supported.
GPRS
General Packet Radio
Service
GSM service for IP-based data transmission. Over GPRS network
connections are established, either to the internet or to private
networks.. Data are transmitted using the internet protocols TCP/IP or
UDP/IP.
OPC OPC covers a series of specification for data exchange in automation
technologies between control devices, sensors etc. and control
systems (see www.opcfoundation.org).
Protocol, transmission
protocol Devices which communicate with one another must use the same rules
for this communication. They must "speak the same language". Such
rules and standards are collectively referred to as a protocol or
transmission protocol. Often used protocols are, for example, TCP/IP
and PPP.
COM-Port The term "COM port" (communications port) is used to describe a serial
interface (V.24, RS-232) on a Windows PC. Application programs use
COM ports for data transmission to various devices such as modems,
PCs, terminals etc.
