AirLink Raven II CDPD Modem
User’s Manual
1. Introduction
This manual covers information for first-time setup and configuration of your
AirLink CDPD Raven II Modem, as well as technical details on this modem.
For detailed information on specific modem parameters please read the
AirLink Raven/PinPoint CDPD Modem User’s Manual. The parameters
for the Raven II are at this time identical to those of the Raven.
Updates to this manual and other manuals may be obtained online at:
http://ww.airlink.com/modems
What is CDPD?
CDPD is a technology used to transmit packet data over cellular voice
networks. It is ideal for wireless applications. It is also more cost effective
than circuit-switched cellular data for small amounts of data. It provides
instantaneous response for data communications because there are no dialing
delays. Built-in encryption maintains the security of the application data over
the air.
1.1 The CDPD Network
Figure 1 – Raven II in CDPD Environment

The Raven's rugged form factor is ideal for industrial and commercial
applications that require real-time communications. The Raven provides
wireless data communications for a variety of applications, such as oil and
gas monitoring, public safety, automated signs, financial transactions, and
security systems. It works with Remote Telemetry Units (RTUs) from several
manufacturers (configuration instructions are detailed in the
Raven/PinPoint User’s Manual).

2. Getting Started
This section covers:
• Getting an IP address from a CDPD Service Provider.
• Setting up Windows to configure the modem with Wireless ACE.
• Reading the lights on the modem to ensure your connection is
working.
2.1 Contacting the CDPD Service Provider
The first step you must take before using your AirLink modem, is to contact a
CDPD Service Provider in your area. You will need to obtain the following
information from your Service Provider (or carrier):
• You need a CDPD account for each modem. The carrier will provide
an IP address for each account. You will need to give them the
modem’s Equipment ID (EID) which can be found on the label on top
of the modem.
The IP address is a valid Internet address and is matched up with
your unique EID.
• Ask about Side Preference - Does your Service Provider provide
service on the A-side or B-side? Is there another CDPD Service
Provider in your area?
If you have CDPD service on one side only and will not be using the
modem outside this area, set the side preference to A only or B only.
If the modem will be used in other areas and you want to use any
other CDPD service that is available, set your modem to "A-side
preferred or "B-side preferred." Ask your Service Provider about the
costs of using CDPD services other than them.
WARNING: Sometimes there are additional costs if you use a side
other than your carrier’s.
2.2 Configuring the Modem
Now that you have the IP address and Side Preference for your modem, you
will need to hook it up to a PC to configure the Raven II with the correct
parameters.
There are two ways to accomplish this:
1. Use AT commands via a Terminal emulation program to configure
the modem (see Raven/PinPoint User’s Manual for further
instructions on this method).
2. Use Wireless ACE on a Windows computer to configure the modem.
This is the recommended method that is detailed in this manual.

AirLink Raven II CDPD Modem
Page 4 AirLink Communications, Inc.
Wireless ACE needs a Dial-Up Networking (PPP) connection to talk to the
modem via Windows. Before configuring the PPP connection, first do the
following:
• Verify no other modems are installed that will conflict with your
AirLink modem, and verify there are no applications running that
will interfere with the COM port you are using. (See Adding the
Modem for more information.)
• TCP/IP must be installed on the system. Verify this by checking
Control Panel→
→→
→Network.
• Dial-Up Networking must be installed which provides the PPP
connection for communicating with your AirLink modem. You can
verify this by checking:
Control Panel→
→→
→Add/Remove Programs→
→→
→Windows
Setup→
→→
→Communications→
→→
→Dial-Up Networking
It should have a black checkmark next to it. If not, check the box.
You may be prompted for your Windows CD to install DUN. After
installation, you may have to reboot.
• Ensure you have a disk labeled "Modem Utilities" (or you have
previously installed another AirLink Product from a CD).
Otherwise you will be directed to various website links in this
manual for finding the files you will need.
Each of the following sections will walk you through how to do the above,
step-by-step, and get your Raven II working so you can begin using it.
The Dial-Up Networking (PPP) configuration in this manual uses
Windows ME (Millennium Edition) setup screens for examples. This
setup is very similar to a Windows 95/98 configuration.
For precise instructions on a particular Operating System setup please check
the Appendix of the Raven/PinPoint User’s Manual (available online at
http://www.airlink.com/modems and select the Raven II support page), or go
to our website instructions at http://www.airlink.com/help and select the
Operating System you are installing on for step-by-step instructions online.
2.2.1 Adding the Modem in Windows
Your computer must have Windows ME (or some other version of Windows
for using Wireless ACE) and the computer must have an available serial
(COM) port to which you will attach your Raven II.
Important: Ensure the serial or COM port you will be using on your
computer is available. Below are the items you can check so that your
AirLink modem will work properly in Windows.
• Do you have any software running that uses a COM port? Confirm
that the Windows computer that you are using does not have any
software loaded that may interfere with the COM port you're going to
use. For example, HotSync - software used for communicating with the

User’s Manual
AirLink Communications, Inc. August 9, 2001 Page 5
PalmPilot can occupy the COM port even if you do not have your
PalmPilot connected to that COM port at this time.
Check any software that loads when your computer starts up - any
software that appears as an icon on your Windows Taskbar - and
Disable/Exit any applications that normally use a COM port.
• Do you have another modem installed? Older internal modems can
cause COM port conflicts. PC Card (PCMCIA) modems in laptops can
switch the COM port number of your built-in COM port. For example,
your built-in COM port is COM1, but when you install your PC Card
modem, that modem becomes COM1 and your built-in COM port becomes
COM2.
Remove your PC Card modem until you verify your AirLink Modem is
working, or ensure your internal modem won't be conflicting with the
COM port your AirLink modem is attached to.
• Infrared ports on laptops/desktops may cause similar conflicts. They too
can change the COM port number, or sometimes “share an interrupt”
with an existing COM port which can cause your serial port not to work
(since the IR port is usually active by default). Check your BIOS settings
or computer manual to disable this port, or ensure it will not be
conflicting.
Now setup the Raven II on the computer:
1. Plug in the AC adapter and attach it to the modem. Verify the Pwr
light is lit.
2. Attach the antenna to the modem.
3. Connect the PC to the modem with a standard DB-9 male connector
for the modem end, and a DB-9 or DB-25 on the other end for the PC.
The cable wiring should be straight through, not a null-modem cable.
(This cable may be provided with your modem.)
4. If you have previously installed another AirLink product (like ATS)
from a CD, then skip to step 6.
Insert your “Modem Utilities” disk into the computer. (Or download
the Windows modem driver from http://www.airlink.com/modems.)
5. Copy the file mdmarlnk.inf to the Windows' INF directory. Usually
this is "C:\Windows\Inf".
NOTE: This is a hidden directory and you will not see it with a
default configuration. Turn on the ability to view hidden files in your
Windows Explorer to see the directory. Select "Show all files" under
View→
→→
→Folder Options→
→→
→View.
6. Open Control Panel→
→→
→Modems→
→→
→Add. This brings up the "Install
New Modem" dialog box.
7. Select Other then Next. This changes the dialog box.

2.3 Installing and Using Wireless ACE
This section walks through installing Wireless ACE and then using it to
initially configure your modem.
Before proceeding with installing and using Wireless ACE, you must first
have configured the Dial-Up Networking connection on your system. (See
Configuring the Modem for details.)
Wireless ACE (or ACE) is a Windows-based utility that is used for
configuring or checking status on your AirLink CDPD Modem either locally
or remotely. ACE needs a PPP connection to talk to the modem over a serial
port (a local connection). This is required for initial configuration of a modem.
Note: Some of AirLink’s other products will install Wireless ACE along
with it. If another AirLink product is installed, check to see if you see a
Wireless ACE icon in its Program Group. This installation assumes
Wireless ACE was only provided with the “Modem Utilities”disk.
1. Insert the "Modem Utilities" disk.
2. Go to Start→
→→
→Run and type in A:\acesetup.exe
3. You'll be prompted for the default directory C:\ACE, hit Enter and
this installs Wireless ACE to C:\ACE on your hard drive.
Note: If you download ACE from the AirLink website, it will be in the
form of a ZIP file, in which case the contents should be extracted to
C:\ACE. (You can download the file from http://www.airlink.com/ace)
4. Start Wireless ACE by double-clicking on ace.exe (or creating a
shortcut for it). You should see the following...
Note that the Reg (Registered) light is red, and occasionally the Link
light turns red. The modem is trying to register on the CDPD network
and cannot because it doesn't have a valid IP address yet.
If you see a picture of the modem with a red X, it means Wireless ACE
cannot communicate with the modem. Check that:
• The modem is On.
• The cable is properly installed.
• The antenna is on securely.
• Dial-Up Networking has established a connection to the modem.
• If you are on a LAN, ensure your machine’s IP address is not in
the 10.x.x.x network (e.g.: 10.0.0.1 or 10.1.23.5, etc.)
• If you receive an Error 629 or Error 630 while connecting to the
modem with DUN, ensure there is nothing else on the COM port -
software like HotSync, internal modems, or PC Card (PCMCIA)

User’s Manual
AirLink Communications, Inc. August 9, 2001 Page 15
modems. Also ensure you are set for the correct baud rate.
Default is 9600.
• see the Troubleshooting section for more.
5. Select the Maximize button (the arrows button). This causes Wireless
ACE to display its Status Screen.
6. Select Tools→
→→
→Communications Options. This causes ACE to
display the Communications Options Dialog box.
7. Select Local Host (PPP Direct to Modem) radio button, ensure either
“Only for Local” or “For Local and Remote Modems” is selected in the
AutoDial-Up (Window DUN) box.
8. Select the OK button.

9. Select the Configuration button. This causes Wireless ACE to
display its Configuration Screen:
10. Change the modem password. The default password is 12345. You
need to change the password to your modem. Passwords can be case
sensitive and include numbers. Use Options→
→→
→Change Modem
Password... or Ctrl-H. The password can be up to eight characters in
length.
11. Double-click on the New Value column for each of the following to
change it:
• Side Preference – enter the side preference that your CDPD
Service Provider gave you. This is important so you are not
overcharged for "roaming" to another CDPD carrier.
The CDPD RF channels are divided into side A and side B. This
enables two carriers to provide service in the same area.
The choices are:
1 = A only
2 = B only
3 = A preferred
