AL7024S Quick Start Manual 1. First steps first 1.1 Checklist for first Tests Instruction STEP 1 Test SIM-card with a handy, decide if you want to use a PIN-code or not and note it. 2 Connect Hardware (5V-supply, RS-232-interface with 5V-levels, Antenna, SIM-card) 3 Set serial-port baud-rate of DTE to 115200 baud, 8n1, hardware-handshake (Soft-handshake not supported). The module should react already to ATCommands, even if it is not connected to a network.
AL7024S Quick Start Manual 1.2 Initialisation-Steps: The AL7024S can store a set of parameters (please see also command “AT&W” in the “AT command manual”). The RS232 interface parameters can also be stored. Our Socket Modems AL7024S are preset to “AT+IPR=115200” baud rate”. You should think about the initialisation-steps that should be made every time the AL7024S is poweredup. For details see also chapter 5.2 in the “Developer’s Guide”.

AL7024S Quick Start Manual 4. Troubleshooting-guide There is never a simple "no connection". There are many causes for this, which can be excluded step-by-step. If you never had a successful data-connection, you should test first with an analog modem at the other side. Also, if possible, avoid problems with local company-exchanges, using a direct phone-line. This applies specially if you call to a digital "modem" (ISDN-TA). You can test these configurations later.
AL7024S Quick Start Manual Ringing To test this, call first to a normal telephone and look, if it is ringing. (ATDxxx; with semicolon for speech-mode). Call also from telephone to GSM. (Response RING or INCOMING SPEECH CALL) (This is to see, if the GSM-network connects, or if it is a problem with numbering of house-exchange, or bad configured ISDN-phones) Make speech-connection to phone Do the same and pick the phone up, the GSM should show "CONNECT (SPEECH)".
AL7024S Quick Start Manual Make data-connection Connect a speaker or a phone to the analog-line to obtain more information about the progress of the connection.(hear the ring and the progress of connection buildup.) Make call in data-mode (ATD without semicolon). Control, if it is ringing ("RING" response), ring on phone or speaker. Control, if call is answered (ring stops, data-sounds can be heard. ISDN: connectresponse on terminals.) Eventually, connection disconnects again. Causes: a.
