AL7024S Quick Start Manual

1.2Initialisation-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 powered- up. For details see also chapter 5.2 in the “Developer’s Guide”.

•Power-up the AL7024S Socket-Modem

•Pull-down the Reset-pin for at least 800ms.

•Eventually adjust RS232-parameters.

•Send “AT” to modem and wait for response.

•If SIM-Pin is required, enter it with AT+CPIN=”xxxx”

•Configure the modem to your required application: Examples:

AT+CMEE, AT+CR, AT+CRC, ATV, AT+CREG, AT+CGREG.

(AT+CREG indicates Network-status).

Set default-storage for phone book and SMS.

For using Microphone- and Speaker-pins, you should set: AT+MAPATH=1,2 / AT+MAPATH=2,2,1

•For data connections the following commands / parameters are always needed:

AT+CBST	for protocol-selection
AT+MIPCALL	for TCP/IP
AT+MIPOPEN	for TCP/IP
AT+CGDCONT	for GPRS

If you want to use GPRS with Windows, you should set AT+CGDCONT
