Important Notice
Because of the nature of wireless communications, transmission and reception of
data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or
be totally lost. Although significant delays or losses of data are rare when wireless
devices such as the AirLink Communications modem are used in a normal manner
with a well-constructed network, the AirLink modem should not be used in situations
where failure to transmit or receive data could result in damage of any kind to the
user or any other party, including but not limited to personal injury, death, or loss of
property. AirLink Communications, Inc., accepts no responsibility for damages of any
kind resulting from delays or errors in data transmitted or received using the
AirLink Communications modem, or for failure of the AirLink Communications
modem to transmit or receive such data.
Safety and Hazards
Do not operate the AirLink Communications modem in areas where blasting is in
progress, where explosive atmospheres may be present, near medical equipment,
near life support equipment, or any equipment which may be susceptible to any form
of radio interference. In such areas, the AirLink Communications modem MUST BE
POWERED OFF. The AirLink Communications modem can transmit signals that
could interfere with this equipment. Do not operate the AirLink Communications
modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft,
the AirLink Communications modem MUST BE POWERED OFF. When operating,
the AirLink Communications modem can transmit signals that could interfere with
various onboard systems. The driver or operator of any vehicle should not operate the
AirLink Communications modem while in control of a vehicle. Doing so will detract
from the driver or operator's control and operation of that vehicle. In some states and
provinces, operating such communications devices while in control of a vehicle is an
offence.
Limitation of Liability
The information in this manual is subject to change without notice and does not
represent a commitment on the part of AirLink Communications, Inc. AIRLINK

User Guide
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.

Redwing GPRS User Guide Version 1.08
1.1 Redwing Product Overview
The AirLink Redwing GPRS is a rugged, full duplex GPRS modem that provides
wireless transport capabilities for fixed and mobile applications. GPRS is an efficient
and secure wireless technology that works well for fixed or mobile applications.
The Redwing's rugged form factor is ideal for industrial and commercial applications
that require real-time communications. The Redwing provides wireless data
communications for a variety of applications, such as telemetry, public safety,
SCADA, traffic control, traffic metering, transit arrival systems and more.

Redwing GPRS User Guide Version 1.08
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 User Guide Version 1.08
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.

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.)

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
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

indicates the radio is transmitting

The power is on.

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.
3.2.1 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
3.2.2 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
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. Most companies will be using a custom APN that allows
them to communicate with all

at&w
You only need to do this once after powering up. Henceforth, the modem will use this
setting to attach to the GPRS network.

Using AT Commands
Redwing GPRS User Guide Version 1.08
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). Set up to connect to the modem by either method
described in Section Error! Reference source not found..
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
You should get a response of "0" or "OK".
To turn on echo and verbose modes, type the following:
ATE1V1
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
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.
