Functional description The GS-01 modem provides RS-232/V.24 up to 9 600 bit/s connections over GSM networks. It can be used instead of serial cable to link PLC’s, data loggers, security and surveillance system or for data acquisition. It is possibility to have an external signal (DTR) to trigger the modem to call a pre-set number. This makes it ideal for alarm monitoring and remote diagnostics from unmanned stations.

4.0 Installation 4.1 SIM-card To get the modem to work is it necessary to have a GSM subscription from a network provider. They will provide you with a SIM card that should be mounted in the SIM card holder. Use a sharp element and press the yellow button to eject the holder. Mount the SIM card in the holder and make sure it is correctly installed before it is pushed back into the modem. 4.2 Antenna Remove the protection from the SMA connector and connect the enclosed antenna.
5.0 Configuration Note! To be able to configure the modem all the AT-commands has to be written with capital letters, e.g. AT+CPIN. In this manual we have only described the most frequently used commands. For the complete AT-commands manual, please, visit our web, www.westermo.se where you can find it in PDF-format. General commands +CGMM – Request model identification This command is used to get the supported bands (GSM 900, DCS 1800 or PCS 1900).
Call control commands D – Dial command Command syntax: ATD [I / i] [G/g] [;] ATD> [I / i] [G/g] [;] ATD> mem [I / i] [G/g] [;] ATD> [I / i] [G/g] [;] The ATD command is used to establish a speech, data or fax call. For a data or fax call, the application sends to the GSM module the following ASCII string: (the bearer has to be selected before with the +CBST command) ATD where is the called phone number.
Direct dialling from a phonebook location (stored in SIM card) can be done with the following command: ATD> ; for calling from the selected phonebook (by +CPBS command) ATD>”BILL”; for calling ”BILL” from the selected phonebook ATD> mem (mem is ”SM”, ”FD” or ”ON”, see +CPBS command) is a way to directly dial from a phonebook number.
H – Hang-Up command The command ATH (or ATH0) is used by the application to disconnect the remote user. In case of multiple calls, all calls are released (active, held and waiting calls). The specific Wavecom command ATH1 has been appended to disconnect only the outgoing call. It can be useful in case of multi communication.
AT%Dn – Automatic dialling with DTR This command allows to activate and deactivate automatic dialling of the phone number stored in the first location of ADN phonebook. The number is dialled on DTR OFF to ON transition. Sets commands: Options: ; AT%D0 AT%D1; AT%D1 Example: Application to GSM GSM to application AT%D[;] n (0–1) for activate or deactivate the automatic dialling. Informs the module that the number is a voice rather than a fax or data number. Deactivates automatic DTR dialling.
ATS0 – Automatic answer This S0-parameter controls the automatic answering feature of the mobile.

Application to GSM AT+CPMS=? Possible message storages GSM to application +CPMS: ((”SM”,”BM”), Read, list, delete: SMS or (”SM”)) CBM.
Application to GSM GSM to application Application to GSM AT+CMGF=0 OK AT+CMGS=14 0001030691214365000004 C9E9340B +CMGS: 4 PDU message format PDU mode valid Send complete MSG in PDU mode, no SC address GSM to application MSG correctly sent, OK is returned The message is composed of the SC address («00 means no SC address given, use default SC address read with +CSCA command) and the TPDU message. The length of octets of the TPDU buffer is 14, coded as GSM 03.
+CSDH – Show text mode parameters This commands gives more informations in text mode result codes. These informations are in brackets in commands +CMTI, +CMT, +CDS, +CMGR, +CMGL. Application to GSM GSM to application AT+CSDH? +CSDH: 0 OK Current value Do not show header values +CNMI – New message indication This command selects the procedure how receiving the message from the network.
: set the rules for storing received CBMs (Cell Broadcast Message) types depend on its coding scheme, the setting of Select CBM Types (+CSCB command) and . Default is 0. 0 No CBM indications are routed to the TE. The CBMs are stored. 1 The CBM is stored and an indication of the memory location is routed to the customer application using unsolicited result code: +CBMI: ”BM”, 2 New CBMs are routed directly to the TE using unsolicited result code.
GSM to application GSM to application +CMGS: 7 OK +CDS: 2, 116, ”+33146290800”, 145, ”98/10/01,12:30:07+04”, ”98/10/01 12:30:08+04”, 0 Successful transmission Message was delivered correctly +CMGR – Read message This command allows the application to read stored messages.
+CMGL – List message This command allows the application to read stored messages, by indicating the type of the message to read.
+CMGS – Send message Command syntax in text mode: AT+CMGS= [ , ] text is entered Command syntax in PDU mode: AT+CMGS= PDU is entered The field is the address of the terminal network to whom the message is sent. To send the message, simply type character (ASCII 26). The text can contain all existing characters except and (ASCII 27). This command is abortable using the character when entering text.
+CMGW – Write Message to Memory This command stores a message to memory storage (either SMS-SUBMIT or SMS-DELIVERS). The memory location is returned (no choice possible as with phonebooks +CPBW). The entering of text or PDU is done similarly as specified in command Send Message +CMGS.
+CMSS – Send Message From Storage This command sends message with location value from storage to the network. Command syntax: Response syntax: AT+CMSS=[, [,] ] +CMSS: or +CMS ERROR: if sending fails If new recipient address is given, it will be used instead of the one stored with the message.
SM from the same . MTI: Message Type Indicator b1=0 & b0=0 -> SMS-DELIVER (in the direction SC to MS) b1=0 & b0=1 -> SMS-SUBMIT (in the direction MS to SC) In text mode is only coded in ”relative” format. The default value is 167 (24 hours).
+CSCA – Service center address This command shall be used to indicate to which service center the message has to be sent. The GSM module has no default value for this address. If the application tries to send a message without having indicated the service centre address, an error will be generated. So, the application has to indicate this address at initialization. This address is then valid all the time. The application may change it if needed.
GSM to application AT+CSCB=1 Application to GSM OK Deactivate the reception of CBMs CBM reception is completely stopped +WCBM – Cell Broadcast Message Identifiers Command syntax: AT+WCBM= [, , ] This specific command is used to read the SIM file EF-CBMI. This file is not used with +CSCB command, the application should read this file (AT+WCBM?) and combine the Message Identifiers with those required for the application.
+WMGO – Message overwriting The +CMGW writes a SMS to the first free location. To write a SMS to a specified location, the +WMGO specific command forces the module to write a SMS (with +CMGW command) to the location specified with +WMGO, but just for one +CMGW command. Command syntax: AT+WMGO= location number of the SIM record to write or overwrite Possible responses: OK if is a valid SMS location, for AT+WMGO=? and for AT+WMGO? +CME ERROR: 21 if is out of the SIM capacity range.
