Redwing GPRS User Guide WARNING The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. 1. Introduction The GSM/GPRS wireless network combines the world’s leading wireless standard—the Global System for Mobile Communications (GSM)—with fast, packet-switched access to data networks such as the Internet. Providing this fast access is the General Packet Radio Service (GPRS). The AirLink GPRS modems are designed to operate in GSM/GPRS networks. Two data services are available in the GSM/GPRS networks: GPRS, a packet switched connection, and SMS, a short message service.. GPRS GPRS is an IP-based service that offers fast, packet-switched access to data networks such as the Internet. It is a mobile service that improves the peak-time capacity of a GSM network. GPRS gives packet-switched access over GSM to external data networks with high peak transfer capacity. The main objective of GPRS is to offer access to standard data networks such as TCP/IP. GPRS is a non-voice service designed specifically for transmitting data. It breaks data messages into separate packets for transmission from the mobile device and sends them to destinations in an external network. Most any Internet-based application or service will run on GPRS. GPRS offers peak throughputs of 40 Kbps (53.6 Kbps raw) Because GPRS capacity is shared among active users in the same coverage area, actual throughputs may vary. GPRS Network Internet

Redwing Network Connection Redwing GPRS User Guide Version 2.01 2. Redwing Network Connection The AirLink Redwing GPRS modems are capable of providing network connections for GPRS and SMS data. 2.1 Internet (TCP/IP) Connections via GPRS When using the Redwing GPRS, remote access to is done via a PPP (TCP/IP) connection to the GPRS network. The GPRS carrier actually provides Internet connectivity, and, therefore, it becomes the ISP for that session. Applications such as web browsing, email, FTP, etc should work as they would normally.

Redwing GPRS Configuration Redwing GPRS User Guide Version 2.01 3. Redwing GPRS Configuration Configuration of the Redwing GPRS modem is done using a terminal emulation program like HyperTerminal in Windows. 3.1 Configuration Procedure 1. Attach the antennas, DB-9 cable and power to the back of the modem. 2. Power on the modem, and ensure the Pwr light is lit. 3. Attach the modem to the back of the PC with the provided DB-9 cable. (Note, if you did not order a cable with your modem, you need a straight-thru RS-232 cable to attach to the modem.) 4. Select Start→ Programs→ Accessories→ Communications→ HyperTerminal. 5. Enter the name of the connection and select OK. AirLink Communications, Inc. Page 4 September 14, 2004

Redwing GPRS Configuration Redwing GPRS User Guide Version 2.01 6. For "Connect using" select the COM port that the modem is on (do not select a modem driver), then select OK. 7. Select 115200 for the "Bits per second." Ensure Data Bits: 8, Parity: None, Stop bits: 1 and Flow control: Hardware. Then select OK. (These are the factory default settings for a GPRS modem. If you get garbled characters when typing AT commands, change these settings and reconnect to the modem. For example, change the baud rate to 57,600 bits per second and connect again, etc.) AirLink Communications, Inc. Page 5 September 14, 2004

Redwing GPRS Configuration Redwing GPRS User Guide Version 2.01 8. Type AT followed by [Enter]. You should receive an "OK" in response. Other AT commands may now be issued to the modem. See Section Using AT Commands for a list of AT commands 3.2 Modem Activation [C3110] The Redwing GPRS modem requires a SIM [Subscriber Identity Module] for the modem’s account activation. Units will usually be shipped with a SIM installed and be ready to operate. If a SIM is installed, and the modem is in GSM/GPRS coverage, the status indicators will look like the following: where the status indicators have the following meanings: GSM indicates GSM coverage if +RSCI=0 indicates GPRS coverage if +RSCI=1 Tx indicates the radio is transmitting Radio The OEM module radio is on and ready to transmit and receive Pwr The power is on. AirLink Communications, Inc. Page 6 September 14, 2004

Redwing GPRS Configuration Redwing GPRS User Guide Version 2.01 If there is no SIM installed or there is no GSM/GPRS coverage, the GSM indicator will be off. Indicating no GSM/GPRS coverage or no SIM installed Connect up to configure the modem as in the Local Configuration Section . If you are unfamiliar with using AT commands, please review the Using AT Commands Section first. 3.3 Modem Activation [C3111] The Redwing GPRS modem requires a SIM [Subscriber Identity Module] for the modem’s account activation. Units will usually be shipped with a SIM installed and be ready to operate. 3.3.1 SIM Check You can check if a SIM [Subscriber Identity Module] is in the Redwing with the AT+CIMI command. If a SIM is in the modem, you will see a response like the following: at+cimi 310380006255650 OK The number is the IMSI [International Mobile Subscriber Identity] which is unique to each SIM. If there is no SIM, there will be a blank response like the following: at+cimi OK 3.3.2 PDP Context Check if the PDP context is correct with the command: AT+CGDCONT? You should get a response like: at+cgdcont? +CGDCONT:1,"IP","proxy","",0,0 AirLink Communications, Inc. Page 7 September 14, 2004

Redwing GPRS Configuration Redwing GPRS User Guide Version 2.01 OK If you get a blank response, you need to set the PDP context. You need the APN [Access Point Name] which you can obtain from the carrier rep or from whomever you received the account. Some companies may be using a custom APN that allows them to communicate with only the IPs in their APN. To set the PDP context: at+cgdcont=1,”IP”,”apn_obtained_from_carrier” at&w The modem will use this setting to attach to the GPRS network. NOTE: These parameters are case sensitive. The “IP” is always upper case, and the APN is usually lower case. AirLink Communications, Inc. Page 8 September 14, 2004

Using AT Commands Redwing GPRS User Guide Version 2.01 4. Using AT Commands Use a terminal emulation program to connect up to the modem either locally (via the serial port of a computer) or remotely (over an existing internet connection on a PC to the modem at a remote location). Sample AT Commands Here is an example of entering AT commands, changing some settings, saving and resetting the modem. (Note that any command you are unsure of is explained in The AT Commands section.) Type AT and press the Enter key. AT<enter> You should get a response of "0" or "OK". To turn on echo and verbose modes, type the following: ATE1V1<enter> You should see an "OK" response if Verbose Mode was properly activated (V1) If you should see a “0” response, your modem is in Terse Mode and the V1 command did not adhere. Try ATV1 again by itself if that happens. You should see an “OK” response now. To set the baud rate, (like 115200), type the following: ATS23=115200,8N1<enter> You should get an "OK" (if in Verbose Mode) Note: Command settings take effect immediately unless otherwise noted in the description. Note: HyperTerm needs to be disconnected and reconnected after each baud rate change to have it take effect. AirLink Communications, Inc. Page 9 September 14, 2004
