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.
1Introduction
The AirLink CDMA modem is designed to operate in CDMA networks. Two services
are available in the CDMA networks: 1xRTT, a packet switched connection, and IS-
95B, a circuit switched connection.
CDMA IS-95B
The AirLink CDMA modem is capable of making IS-95 connections. The modem first
connects to the CDMA network and the network then connects to the call to either
the Public System Telephone Network (PSTN), or to the Internet using QNC. These
calls use an Interworking Function (IWF) to bridge the CDMA network to the PSTN:
Internet
CDMA
Network
IWF
PSTN
For Internet connections, the Interworking function can use a special feature called
QNC (Quick Net Connect). The IWF provides a link to the Internet without going
through the PSTN. Establishing a standard point-to-point call requires the Airlink
CDMA to configure a modem at the IWF. It is the IWF modem that actually connects
to the PSTN and dials the number. Call progress is not directly available to the local
modem, although some information can be exchanged. When the IWF has completed
the handshake with the remote modem, the local modem is advised and the
connection is complete.

CDMA2000 1X
The AirLink CDMA modem provides data capability into the packet service offered
with CDMA2000 1X (1xRTT) technology. CDMA2000 1X offers higher speed data
operations than are available with IS-96 service. IS-95 is limited to 14.4 kbps. 1X
service uses a fundamental channel at 9600 bps and can add supplemental channels
when needed to boost speed to as high as 153.6 kbps on the downlink (network to
modem) and 76.8 kbps on the uplink (modem to network).
1.1 Product Overview
The AirLink Redwing CDMA is a rugged, full duplex 1xRTT CDMA modem that
provides wireless transport capabilities for fixed and mobile applications. CDMA is
an efficient and secure wireless technology that works well for fixed or mobile
applications.
The Redwing CDMA is ideally suited for fixed and mobile Industrial or Commercial
Applications, including Telemetry, SCADA, Public Safety, Mobile Dispatch, Field
Service, Financial Transaction Processing, and Security applications. The CDMA
Redwing enables virtually any PC, PDA, or networking device (router, server, etc) to
access the CDMA/1xRTT data network. The Redwing CDMA can also be used in
installations with many different types of Remote Terminal Units (RTUs),
Programmable Logic Controllers (PLC’s) or other computers that perform metering
and monitoring functions in the oil, gas, water, and transportation industries. The
Redwing CDMA can be a low-cost replacement for many existing landline, private
radio and circuit-switched cellular installations.

2Network Connection Options
The AirLink CDMA Redwing is capable of offering multiple network connection
options. This section will illustrate the different network options that are available.
2.1 Internet (TCP/IP) Connections via 1xRTT
When using the Redwing CDMA, remote access to is done via a PPP (TCP/IP)
connection to the CDMA network. The CDMA 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.
NOTE: Connections to Internet are provided by the carrier.
Corporate network connections are unique and not provided as part of service.

2.2 Circuit-Switched CDMA Connections
Where there is carrier support for circuit-switched connectivity, the Redwing CDMA
is capable of providing traditional Circuit-Switched ‘dial-up’ communications.
Where you would normally use a landline modem or analog cellular dial-up device,
the Redwing CDMA can be a drop-in replacement. The CDMA carrier actually
provides basic connectivity to the Public Switched Telephone Network (PSTN), so all
that is needed is a CDMA activation (phone number) and connection of the serial
cable. For connection to Windows computers, follow the setup profile for a Hayes
Compatible or Standard 33600 baud modem. No special drivers or setup is required.
Practical Applications
Host Modem
The Redwing CDMA can be used as a modem connected to a host PC (or other device)
and provide dial-up connectivity to the Public Switched Telephone Network (PSTN).
Using the Hayes Compatible ‘ATD+Phone Number’ dialing sequence, the modem can
dial any landline telephone modem. The diagram below shows how the application
may be used.
PSTN
CDMA
Network
Circuit-
Switched
Destinations
Remote Modem
The Redwing CDMA can be used as a modem connected to a remote PC (or other
device) and provide two-way dial-up connectivity to the Public Switched Telephone
Network (PSTN). Using the Hayes Compatible ‘ATD+Phone Number’ dialing
sequence, the modem can dial or receive landline connections. The diagram below
shows how the application may be used as a remote device.

3Modem Configuration
Modem configuration of the Redwing CDMA modem is done using a terminal
emulation program like HyperTerminal in Windows.
IMPORTANT NOTE: Wireless ACE cannot be used to configure the Redwing
CDMA modem from a Windows computer. Only a terminal emulation
application may be used.
3.1 Local Configuration
1. Attach the antennas, DB-9 cable and power to the back of the modem.
2. Power on the modem, and ensure the On 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.

Redwing CDMA 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: 1and Flow control: Hardware. Then select OK.
(These are the factory default settings for a Redwing CDMA 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 7 September 14, 2004
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 5 for a list of AT
commands
3.2 Modem Activation [Model C3111]
The activation process is unique for each carrier. See the appropriate CDMA Setup
Wizard on AirLink’s web site: www.airlink.com > Support > Downloads and Support
Documents > Modem Utilities.
3.3 Modem Activation [Model C3110]
The Redwing CDMA modem may be already set up to register online with a phone
number, etc. pre-configured into it (by AirLink Communications, Inc.). When a
modem is registered on the network and working, the lights will look like the
following:
Tx
Reg
Rx
Reset
Redwing CDMA
Pwr
Note that the Reg light may be flashing at first. When it is registered on the
network, it will go solid. Also the Tx (transmit) and Rx (receive) lights will flash as
data is transferred to and from the modem on the network.
If your modem lights look like the above when the modem is powered on, you do NOT
need to configure the phone number, etc. into the phone and may skip this section.

Redwing CDMA User Guide Version 2.01
AirLink Communications, Inc. Page 8 September 14, 2004
If however the Reg light does not go solid after a few minutes, your modem may
need to be configured with a phone number and other parameters. Or if you have
service ordered and a phone number for your modem, you may add these parameters
yourself by doing the following:
•Connect up to configure the modem as in Section 3.1.
•If you are unfamiliar with using AT commands, please review Section 5 first.
•Enter the Lock code from your provider using AT~NAMLCK (as described
below).
•Enter the phone number, System ID and Network ID with the
AT~NAMVAL command (described below). The parameters are saved
automatically once entered.
•Reset the modem by pressing the Reset button on the front of the modem, or
power-cycle it.
The modem should now come online registered.
~NAMLCK
NAMLCK ("NAM Lock")
AT~NAMLCK=nnnnnn (nnnnnn = Lock Code from carrier)
Example: AT~NAMLCK=123456 - uses 123456 for the NAM Lock value
The NAM is the “Number Assignment Module”. The NAMLCK command
unlocks the ability to set the NAM parameters (to provision a an account).
The NAMLCK is the modem’s 6-digit OTSL (One Time Subsidy Lock), MSL
(Master Subsidy Lock), or SPC (Service Provisioning Code). The carrier
provides this number to you at time of service activation. If the number is
accepted by the modem, the OK result code is returned. If the number is
rejected, the ERROR result is returned. If three successive Errors are
returned, the modem must be reset to allow any further attempts.
Note: The modem permits 99 failures of this command during its
lifetime. After that, the modem becomes permanently disabled.

~NAMVAL
NAMVAL (“NAM Value”)
AT~NAMVAL=<nam>[,<num>,<sid>,<nid>]
Examples:
1. AT~NAMVAL=0 - Sets NAM 0 as the active account
OK {Response}
2. AT~NAMVAL?0 - Queries the active account NAM0
NAM: 0
NUM: 8135551212 (10 digit phone number)
SID: 40 (System ID)
NID: 65535 (Network ID)
OK {Response}
3. AT~NAMVAL=0,8135551212,40,65535 - Assigns phone number
813-555-1212, a SID and NID to account 0.
The NAMVAL command has 3 functions:
Setting the Active Account index
The modem supports two accounts. One is always the ‘active’ account.
Using the <nam> parameter followed by a 0 or 1 will set the active account
to be used.
Reading the current account information
The query form of the command will report the details of the active
account:
Write account activation data
Following successful unlocking by ~NAMLCK, this command can be used
with all parameters to write the account data to the modem. If ~NAMLCK
has not been successfully executed, the modem returns ERROR. The
carrier will tell you what numbers to enter for NUM, SID, and NID. The
choice of NAMVAL is up to you. Following writing the values, the modem
must be reset.
