36 Functions INSYS GSM/GPRS small 12.5 Automatic Baud Rate Detection Serial Connection Note Functional reliability! Undefined settings of baud rate and data format may affect a reliable function. It is recommended to select a fix baud rate and thus deactivating the automatic baud rate detection for a reliable operation. The automatic baud rate detection enables a continuous automatic adjustment of all parameters (baud rate, (data format only GSM small)) of the serial interface at the INSYS GSM/GPRS small. The device will detect during operation, which baud rate and which data format is applied to the serial interface. With each incoming AT command (according to the character string "AT"), the parameters for the interface of the INSYS GSM/GPRS small will be checked and adjusted, if necessary. Automatic baud rate detection does not work for baud rates below 1200 baud. Configuration with HSComm In order to enable the automatic baud rate detection, select on the Serial interface tab in the Baud rate field the Autobaud setting (Figure 6, page 30, position 8). Configuration with AT commands To set the baud rates, enter one of the following baud rates for <n>: 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, , or bps. AT+IPR=<n> If 0 is configured for <n> here, automatic baud rate detection is enabled. 36

37 INSYS GSM/GPRS small Functions CSD Data Connection to ISDN/PSTN For a data connection with a device outside the GSM network (PSTN or ISDN TA) the right protocol has to be selected. This setting is not important for data connections with a GSM device. The automatic negotiation of the connection protocol enables the INSYS GSM/GPRS small to negotiate the largest possible connection speed to the remote terminal while the connection is established. The speed depends on the settings and the abilities of the modem at the remote terminal. Via the connection protocol, the connection speed can be set through the phone line. If nothing is defined, the INSYS GSM/GPRS small will automatically try to determine the optimum connection parameters. Configuration with HSComm In order to configure the protocol, select on the Serial interface tab in the Protocol field the respective setting (Figure 6, page 30, position 13). Configuration with AT commands To configure the modulation standard and thus the connection speed, use the command: AT+CBST=<service> Please find the possible parameters for this command in the AT Command reference chapter. To display the current settings: For a list of possible parameter of the command, enter: AT+CBST? AT+CBST=? 37

38 Functions INSYS GSM/GPRS small 12.6 Data Flow Control (Handshake) The data flow control ensures that the data transfer is interrupted as soon as the modem buffer exceeds a certain level. Two data flow control options are available: Via the control lines RTS and CTS, or via the control characters XON/XOFF which are inserted into the data stream Hardware Data Flow Control (RTS/CTS) The hardware data flow control works in two directions. When the critical buffer level is exceeded, the modem will set the CTS line to "low" and will thus indicate to the application to interrupt the dataflow. When the buffer is emptied sufficiently for the INSYS GSM/GPRS small to be able to receive data again, the CTS line is set to "high". Reversely, the application can also indicate to the INSYS GSM/GPRS small to interrupt the data flow. This is done via the RTS line. If it is set to "low", the modem will interrupt the data flow to the application. The application will set it to "high" to request data from the INSYS GSM/GPRS small. The data flow control with RTS/CTS behaviour is active by default. Configuration with HSComm Select the type of data flow control or switch it off completely on the "Serial interface" tab in the "Handshake" panel (Figure 6, page 30, position 1). Configuration with AT commands In order to enable the data flow control and to set the type to RTS/CTS, use the command In order to disable the data flow control, use the command AT\Q3 AT\Q0 38

39 INSYS GSM/GPRS small Functions Software Data Flow Control (XON/XOFF) When the input buffer of the modem exceeds a certain fill state, the modem will insert an XOFF character into the data stream to the application. This character will cause the application to send no more data. It will depend on the according application software if the XON/XOFF data flow control is supported. After the input buffer of the modem is emptied so much that data can be received again, the modem will send an XON character to the application. This character will cause the application to send data to the modem again. Analogously, the application can insert XON/XOFF characters into the data stream to switch the data flow on and off. The XON/XOFF data flow control is only available when the transmitted data do not contain the characters XON or XOFF, which usually appear only in actual ASCII texts (7 bit). When binary data (programs, etc.) are transmitted, or in the XMODEM transmission protocol, for example, occasionally appearing XON or XOFF characters would disturb the operation. Configuration with HSComm Select the type of data flow control or switch it off completely on the "Serial interface" tab in the "Handshake" panel (Figure 6, page 30, position 1). Configuration with AT commands In order to enable the data flow control and to set the type to XON/XOFF, use the command In order to disable the data flow control, use the command AT\Q1 AT\Q0 39

40 Functions INSYS GSM/GPRS small 12.7 Establish or Accept a Data Connection The INSYS GSM/GPRS small can call another modem via the GSM network and establish a data connection. After dialling a number, the INSYS GSM/GPRS small synchronizes with the called modem and opens a data connection with the transmission speed, allowed by the GSM network. Usually, this is 9600 bit/s. The speed, which is configured at the serial interface of the INSYS GSM/GPRS small at the time of connection establishment, will not be changed. All incoming characters are transmitted to the called modem during an active data connection. Therefore, AT commands are not processed during a connection. The INSYS GSM/GPRS small must be switched to command mode using the Escape sequence that it is able to process AT commands during an active data connection again. Then, the local INSYS GSM/GPRS small processes the entered characters as AT commands and does not transmit it top the remote station. In the same way, the INSYS GSM/GPRS small can accept an incoming connection. It picks up after the configured number of rings and opens a connection. Configuration with AT commands In order to establish a data connection with the INSYS GSM/GPRS small, use the command Replace <phonenumber> with the phone number of the remote station. If another modem accepts the connection, the INSYS GSM/GPRS small reports If the remote station is busy, the IN- SYS GSM/GPRS small reports If no connection with the remote station can be established, the INSYS GSM/GPRS small reports An incoming call is signalled by ATD<phonenumber> CONNECT BUSY NO CARRIER RING In order to change into command mode, use the escape sequence Before and after, no data may be transmitted for 1 second that the IN- SYS GSM/GPRS small changes into command mode. In order to change back from command mode to regular data transmission, use the command +++ ATO 40

41 INSYS GSM/GPRS small Functions In order to accept an incoming connection, use the command In order to configure the number of ring tones, after which the INSYS GSM/GPRS small picks up and accepts the connection, use the command Replace <n> with the number of ring tines (<n> = 2 255, <n> = 0 disables the function). In order to terminate a connection and make the INSYS GSM/GPRS small hang up, use the command ATA ATS0=<n> ATH 12.8 Automatic Call Acceptance With the automatic call acceptance, the INSYS GSM/GPRS small accepts every call after the configured number of ring tones. Configuration with HSComm In order to enable the automatic call acceptance, activate the check box auto answer (Figure 5, page 28, position 23) on the Basic settings tab. Configure the desired number of ring tones (Figure 5, page 28, below position 23), after which the INSYS GSM/GPRS small picks up. Configuration with AT commands In order to enable the automatic call acceptance, use the command In order to disable the automatic call acceptance, use the command In order to configure the number of ring tones, after which the INSYS GSM/GPRS small accepts the call, use the command Replace <n> with the number of ring tones (<n> = 2 255).

43 INSYS GSM/GPRS small Functions Automatic Execution of AT Commands The command AT^SCFG allows to execute functions (AT commands) time-controlled or via activating the DTR control line. Up to 3 actions can be configured for time-controlled processes. One action can be configured for triggering via DTR. In case of time-controlled functions, the internal timers start over after a restart or reset. This is also valid when entering ATZ or AT&F! The most important functions for an application are explained with examples in the following. These examples are also used in the HSComm for GSM; Automatic PIN entry and login after restart Automatic reset Alarm via DTR control line If all functions are configured in the configuration software HSComm, all memory locations are occupied. The settings of this command are only stored by the command AT^SMSO. This command shuts the {{{PRODUKTBEZEICHNUNG}}} down. It can be restarted by briefly disconnecting the power supply. 43

44 Functions INSYS GSM/GPRS small Automatic PIN Entry and Login after Restart This function allows a login into the GSM network and the transfer of the PIN by the IN- SYS GSM/GPRS small. Configuration with HSComm The simplified PIN entry via the software HSComm is described in the Entering the PIN of the SIM card section. Configuration with AT commands In order to configure an automatic login into the GSM network, use the command Replace <time> with the time in the format <hhh:mm:ss> (e.g. <000:00:06> for 6 seconds), which has to expire before the login takes place. In order to configure an automatic PIN transfer, use the command Replace <PIN> with the PIN of the SIM car and <time> with the time in format <hhh:mm:ss>, which has to expire before the PIN is transferred. After the configured time has expired after a restart, the reply appears at the serial interface Then, the INSYS GSM/GPRS small is logged in into the GSM network. In order to disable the automatic login into the GSM network, use the command In order to disable the automatic PIN transfer, use the command AT^SCFG= AutoExec,1,1,0,0, AT+COPS=0, <tim e> AT^SCFG= AutoExec,1,1,1,0, AT+CPIN=<PIN>, <time> ^SCFG: Auto- Exec,1,1,0,0, AT+COPS =0 ^SCFG: Auto- Exec,1,1,1,0, AT+CPIN =<PIN> AT^SCFG= AutoExec,0,1,0 AT^SCFG= AutoExec,0,1,1 All settings made with the command AT^SCFG, are only stored after executing the command AT^SMSO. In order to store the settings, use the command AT^SMSO 44

45 INSYS GSM/GPRS small Functions Automatic Reset To avoid a faulty registering status of INSYS GSM/GPRS small during infrastructure changes of the GSM network (software updates of the databases, temporary network extensions, e.g. for fairs), the device should be periodically unregistered and reregistered, or re-started and initialized. Configuration with HSComm In order to enable the automatic reset, activate on the Basic settings tab in the System monitoring tab the radio button software reset and enter the time, which has to expire, before a reset will be performed (Figure 5, page 28, position 12). Configuration with AT command In order to configure an automatic reset, use the command Replace <time> with the time in the format <hhh:mm:ss> (e.g. <024:00:00> for 24 hours), which has to expire before the reset takes place. AT^SCFG= AutoExec,1,1,2,0, AT+CFUN=1,1, <t ime> The INSYS GSM/GPRS small will be reset after the configured time has expired following a restart. After this reset, the configured functions will also be processed again, which is indicated accordingly at the serial interface. In order to disable the automatic reset, use the command AT^SCFG= AutoExec,0,1,2 All settings made with the command AT^SCFG, are only stored after executing the command AT^SMSO. In order to store the settings, use the command AT^SMSO 45

46 Functions INSYS GSM/GPRS small Alarm via DTR Control Line The INSYS GSM/GPRS small can send a message or establish a data connection when activating the control line DTR of the serial interface (e.g. by opening a COM port at a PC). When using the alarm via DTR control line, we recommend to make the setting AT&D Sending an SMS via DTR Activation The INSYS GSM/GPRS small can send an SMS when activating the control line DTR of the serial interface.
