Raven and PinPoint CDMA
User Guide
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 IS95B, a circuit switched connection. The Raven CDMA can be provisioned to transmit
and receive data using either service.
1.1 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-95 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).

The AirLink Raven and PinPoint CDMA modems are capable of providing network
connections for 1xRTT, Circuit Switched and SMS data.
2.1 Internet (TCP/IP) Connections via 1xRTT
When using the AirLink CDMA modems, 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.

Wireless Ace application, or a terminal emulation program like HyperTerminal in
Windows, or using a telnet application.
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.
AirLink Communications, Inc. Page 5 March 24, 2004
Raven and PinPoint CDMA User Guide Version 1.12
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 Raven 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 6 March 24, 2004
Raven and PinPoint CDMA User Guide Version 1.12
8. Type AT followed by [Enter]. You should receive an "OK" in response.
9. Type ATI1 followed by [Enter]. This displays the modem firmware version
and you should also see "AirLink Communications, Inc." in it which ensures
you are talking to the Raven CDMA modem. (If not, try changing COM
ports.)
Other AT commands may now be issued to the modem. See Section 5 for a list of AT
commands
3.2 Modem Activation
The Raven CDMA modem is usually 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:

Note that the RSSI light may be flashing or solid, showing the strength of the signal.
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.
AirLink Communications, Inc. Page 7 March 24, 2004
Raven and PinPoint CDMA User Guide Version 1.12
If however the Reg light is not lit, 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 for some carrier
accounts 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.
• Use the following command to go into PassThru mode: AT\APASSTHRU
(see section PassThru Mode). Note that this command may take up to 20
seconds to initially complete.
• 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.
• The modem must be physically power-cycled to exit this mode. (This is also
the only way to exit PassThru mode.) Press the Reset button on the front of
the modem.
• It may be necessary to enter the username and password provided by your
service provider in the *NETUID and *NETPW fields. (See Section Error!
Reference source not found..) Use AT&W to save these settings.
(PassThru mode is not needed for those two parameters.)
The modem should now come online registered.
Note that the activation process is unique for each type of service provided
by each carrier. The specific activation process required for your service
and carrier is provided in a separate document available on
www.airlink.com.
3.2.1.1 Syntax for ~NAMLCK and ~NAMVAL
NAMLCK = “NAM Lock”-
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
~NAMLCK
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.
AT Command Format:
AT~NAMLCK=nnnnnn {Input} (nnnnnn = Lock Code from carrier)
OK {Response}
AirLink Communications, Inc. Page 8 March 24, 2004
Raven and PinPoint CDMA User Guide Version 1.12
NAMVAL = “NAM Value”
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.
AT~NAMVAL=0 - Sets NAM 0 as the active account
OK {Response}
Reading the current account information
The query form of the command will report the details of the active account:
AT~NAMVAL?0 - Queries the active account NAM0
~NAMVAL
NAM: 0
NUM: 8135551212 (10 digit phone number)
SID: 0 (System ID)
NID: 65535 (Network ID)
OK {Response}
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. Following writing the
values, the modem must be reset.
AT~NAMVAL=<nam>,<num>,<sid>,<nid>
AT~NAMVAL=0,5105551212,0,65535
OK (Response)
3.3 Remote Configuration with Telnet
Once the Raven CDMA modem is online and registered, it can be contacted from a
remote location by a computer with an internet connection. Using a telnet application
(e.g. HyperTerminal), a connection can be made to the modem and then AT
commands can be issued to configure the modem, just as if a local connection were
being made to the modem.
To connect to the modem remotely using HyperTerminal in Windows, do the
following:
1. Select Start→ Programs→ Accessories→ Communications→
HyperTerminal.
AirLink Communications, Inc. Page 9 March 24, 2004
Raven and PinPoint CDMA User Guide Version 1.12
2. Enter the name of the connection and select OK.
3. Select TCP/IP (Winsock) for "Connect using."
(Note:
Early versions of Windows do not have this option in
HyperTerminal. The Command Prompt application telnet.exe can be
used or any other telnet application.)
4. For the "Host address" enter the IP address of the modem. (AT*NETIP?
will reveal the current device IP address.)
5. For the "Port Number" use 2332. This is the default telnet port number
for the Raven CDMA modem.
6. Select OK.
AirLink Communications, Inc. Page 10 March 24, 2004
Raven and PinPoint CDMA User Guide Version 1.12
7. If the correct parameters have been entered, and the modem is currently
online, you will get a "Password" prompt as shown above.
8. Enter 12345 (default password) and press [Enter]. You will receive an
OK.
Now you may enter any AT commands to the modem as you would if you were doing
a local connection to the modem. See Section 5 for AT commands and their options.
You may want to set local echo in your terminal emulator to see what you type as you
type. There is no remote echo function in the modem.

4.2 Windows Dial-Up Networking (PPP) Configuration
This section describes how to setup a Windows Dial-up Networking connection using
an AirLink CDMA Modem. Windows 2000 Professional was used in this example.
The connection uses PPP to communicate to the modem and gain access the Internet.
Before you start, you need the following:
Administrator privileges to the computer you are configuring or access
granted by an administrator on the network to add/remove devices to your
computer. (Not necessary on Windows 98/ME.)
A 1xRTT user account, password, and access number (obtained from your
CDMA Service Provider).
Windows COM Port and modem set up for a Standard 33600 Modem (see
Section 4.1).
No other program is to be running that is using the serial (COM) port that
your modem is attached to.
OTE: If you have an existing LAN connection, then this dial-up connection to
our CDMA modem may interfere with your existing connection. Once the
connection is initiated it will take over as the "default route" for the majority of
our LAN traffic, specifically Internet access. It's recommended to disconnect your
AN connection before using a PPP connection with your AirLink modem.
f however you want the two connections to co-exist, you can de-select "Use
default gateway on remote network" (described later) and you can use the route
command to setup routing through the modem properly. Go to a Command
rompt and type route /? to find out more, or talk to your administrator.
Now that the modem has been added, the Dial-up connection must be created.
1. Select Start→ Settings→ Control Panel→ Network and Dial-Up
Connections.
2. Double-click on the "Make New Connection" icon.
