Enter PIN AT**PIN If manual network provider selection is required, the network provider identification number must be determined. You will find a chart for the INSYS GPRS 5.0 serial with identification numbers and names in the AT command overview – available at no charge from INSYS.
Connection 5.2 INSYS GPRS 5.0 serial TCP Transparent (GPRS Modem Emulation) In this mode, user data is transmitted transparently via the serial interface and in TCP/IP packets via the GSM/GPRS network. The INSYS GPRS 5.0 serial will act like a conventional modem at the serial interface. The remote terminal for this connection type receives the TCP/IP data and evaluates them directly, or has a virtual COM port driver (see Chap. 6.10 - Virtual Com Port -) to unpack it. 5.2.1.
INSYS GPRS 5.0 serial Connection According to the APN, PPP authentication is required. The necessary information can be obtained from the customer service center of your provider. When using VPN or "FIX IP" solutions, authentification must in general always be used. On the basis of the entered APNs you can determine if a user name or a password is required. user: or pw: PAP authentification, user name or password is required as stated.

INSYS GPRS 5.0 serial Connection For TCP Listen mode, the number of dialing attempts until a device is restarted can be limited with the command AT**TCPLISTENWAITRST=. For example, the INSYS GPRS 5.0 serial is restarted with AT**TCPLISTENWAITRST=3 after the third dialing attempt (20s+80s+320s). This will restart the dialing cycle. The default value for this setting is 255. 5.2.5 Manual connection setup Establish a connection to an IP address or a host with domain name.
Connection INSYS GPRS 5.0 serial The number of dialing attempts for the leased line mode can be limited with AT**LLWAITRST=. For example, the INSYS GPRS 5.0 serial is restarted with AT**LLWAITRST=3 after the third dialing attempt (20s+80s+320s). This will restart the dialing cycle. The default value for this setting is 255. Note This setting increases the availability of the INSYS GPRS 5.0 serial and its application.
INSYS GPRS 5.0 serial Connection If the test is successfully performed, the message "+PPP-IP OK" is displayed. If the test fails, the GPRS connection is terminated (message +PPP-IP RELEASE) and the TCP Listen mode is reestablished. To save costs if there is a problem with availability, the waiting time between the repeat attempts will grow for each subsequent attempt.
Connection INSYS GPRS 5.0 serial 5.2.8 During the connection 5.2.8.1 Keep Alive The data transfer via GPRS is packet-oriented. If no side of the TCP connection sends data, there will be no traffic via the transmission link. This also means that it can not be determined if the remote terminal has disappeared without properly terminating the connection (e.g. due to a failure of the radio network or a failure of the remote terminal).
INSYS GPRS 5.0 serial Connection For a TCP/IP-based transmission such as the “TCP transparent” connection, the transmitted amount of data consists not only of the sum of all user data of the application and the required TCP/IP headers. Each TCP/IP message has a protocol overhead of 40 bytes. For each message there is also a confirmation message from the remote terminal with 40 bytes as well.
Connection 5.3 INSYS GPRS 5.0 serial GSM Data Connection (CSD Call) CSD is the simple modem-like data connection in the GSM network, without using the GPRS service. Remote terminals for the connection can be analogue modems, ISDN adapter, or GSM devices. With the help of HSComm GPRS, the INSYS GPRS 5.0 serial can automatically accept the CSD call. Click on the tab “Basic settings”. 5.3.
INSYS GPRS 5.0 serial Connection Alternatively, the settings can be entered or modified using the terminal program. Incoming connections are indicated in the terminal program. The connection acceptance takes place either automatically, or after a set number of ring signals, or manually with the command ATA. RING ATS0= The indicator for incoming connections can in addition display also the connection type (data, voice) (AT+CRC=1) and the phone number of the caller (AT+CLIP=1) as an option.
Connection INSYS GPRS 5.0 serial 5.3.4 Connection to analogue modems Alternatively, the settings can be entered or modified using the terminal program. To call an analogue modem, an analogue protocol must be set. While doing so it must be observed that the remote terminal has to work with the same protocol as well.

Functions 6.2 INSYS GPRS 5.0 serial Establishing a Connection by Callback The callback function enables the INSYS GPRS 5.0 serial to establish a connection to one of the previously defined remote terminals, when calling from a certain phone number. The remote terminal can be a phone number, an IP address or a hostname with domain. The callback is triggered as soon as a call from a previously defined phone number is indicated at the device.
INSYS GPRS 5.0 serial See also: Functions see Chapter 5.2.2 - Defaults Alternatively, the access control can be set using the terminal program: Default: For the operation within the GPRS network, an Access Point and the GPRS access data must be selected.
Functions INSYS GPRS 5.
INSYS GPRS 5.0 serial Functions Example: A “TCP transparent” connection from the INSYS GPRS 5.0 serial to the service center must be established, controlled by a call (Callback). In addition, the existing possibility to directly call from the service center for emergencies (GPRS failure, performance problems) should be maintained. Only the number of the modem connection for the service center should be made available for this call.
Functions INSYS GPRS 5.0 serial In a second step, the IP target for the callback must be entered. Afterwards, on the tab "Basic settings" the automatic call acceptance after 2 ring tones is required. Alternatively, our example can be set using the terminal program: In general, activate selective call acceptance AT**CLIP=1 Enter allowed phone number 1 AT**CLIP1= +494989949494.
INSYS GPRS 5.0 serial Functions Save the extended functions AT**SAVE Automatic acceptance of an incoming CSD call (for the call of a service center modem) ATS0=2 Save setting for ATS0 AT&W Perform RESET, accept all parameters AT**RESET Note A connection can be established independent from the callback settings via SMS command (provided that the sender number is stored at AT**CLIP=). 6.
Functions INSYS GPRS 5.0 serial tion will be sent to the remote terminal only after the CSD connection is ended. If data is transmitted via GPRS during the CSD call (e.g. via a TCP connection), it may occur that the caller receives the BUSY signal. In this case, the dial-in should be repeated. The rule of thumb would be that the CSD call will be forwarded after a minimum of approximately 30 seconds after the last data byte was transmitted via GPRS.
INSYS GPRS 5.0 serial Functions Save settings AT**SAVE Perform RESET, accept all parameters AT**RESET 6.3.2 CSD priority without caller authentification This function makes it possible that each caller can terminate the existing data connection. In this case, the phone numbers must not be entered. Phone numbers that were entered anyhow, will not be rated.
Functions INSYS GPRS 5.0 serial 6.4.1 Automatic login at restart The INSYS GPRS 5.0 serial can store the SIM card PIN internally, which enables it to log into the GSM network after each restart and reset, without user intervention. All four globally used frequency ranges 850 MHz, 900 MHz, 1800 MHz and 1900 MHz are supported. At the respective location, the INSYS GPRS 5.0 serial will automatically operate with the frequency range provided by the network provider.
INSYS GPRS 5.0 serial Functions Examples: In our example 1, the INSYS GPRS 5.0 serial will be logged out and back in every 3 hours. Alternatively, the scheduled logout/login can be set, changed or deleted using the terminal program. AT**LOGOUT=[,] Our example – 3 hrs. AT**LOGOUT=3 In our example 2, the INSYS GPRS 5.0 serial performs a restart every 3 hours. Alternatively, the scheduled logout/login can be set, changed or deleted using the terminal program.
Functions 6.5 INSYS GPRS 5.0 serial Automatic SMS Processing Note: The sending time of an SMS from the sender to a recipient depends on the pertinent provider of the service number. Due to the network load and the time of day, the time required for sending an SMS may change. The automatic processing of SMS messages can be set using the HSComm. Click on the tab “Basic Settings”. 6.5.1 Activation Activation in HSComm is done by clicking the automatic SMS processing.
INSYS GPRS 5.0 serial Functions Alternatively, automatic SMS processing can be set, changed or deleted using the terminal program.

GPRS General INSYS GPRS 5.0 serial 8 GPRS General 8.1 Application Notes 8.1.1 GSM The provider enables the requested services. A SIM card can be enabled for voice and data services at the same time. The following table lists the usually available cards and contracts.
INSYS GPRS 5.0 serial GPRS General Note The transmitted amounts of data consist of the sum of application user data and the TCP packet data. The information from the TCP/IP packets also represents a network load and will add to the total costs. For the entire data amount it is also important to select parameters adjusted to the application to form TCP packets. These parameters consist of: The maximum set block value (default: 512 byte) (see AT**TCPBLOCK) The maximum waiting period (AT**TCPAGG). 8.
GPRS General 8.3 INSYS GPRS 5.0 serial TCP Transparent This function represents the main characteristic of the extended function. By means of the integrated TCP/IP stacks, the INSYS GPRS 5.0 serial functions as “modem emulation” for the application; the user data are provided transparently via the serial interface ("TCP transparent" connection). There is no need for the application to process any additional protocol stacks. To establish TCP connections to the INSYS GPRS 5.
INSYS GPRS 5.0 serial 8.4 GPRS General IP Addresses/Accessibility The IP address of the GPRS terminal is dynamically allocated by the provider and therefore only temporary. During the next dialin at the provider, a new IP address is allocated. In almost all GPRS networks the IP address can not be accessed from outside as the providers perform the addressing for the switch from GPRS networks to the “normal Internet” via a NAT table (Network Address Translation) to manage the address area limited by IPV4.
GPRS General INSYS GPRS 5.0 serial 8.4.1 Fixed IP address and VPN connection The service provider mdex (http://www.mdex.eu) offers the service "fixed.IP".
