1. Introduction
Congratulations on your purchase of the Harmony 8430 Series
802.11b PC Card wireless LAN adapter. The Harmony 8430
Series 802.11b PC Card is a long range, high performance,
wireless LAN adapter card that complies with the IEEE 802.11b
standard.
The Harmony 802.11b PC Card supports Windows 95, Windows
98, Windows 2000, and Windows NT. Computers with the
Harmony 802.11b PC Card installed “look” like standard
network nodes to the operating system.
The Harmony 802.11b PC Card can be used with other 802.11b
PC Cards to form a stand-alone wirefree Ad Hoc network or
used in conjunction with a Harmony infrastructure to provide
mobile clients with wirefree access to an Ethernet network.
Proxim is the leading supplier of wirefree networking solutions.
Proxim’s unmatched expertise in spread spectrum radio network-
ing technology, combined with the company’s extensive experi-
ence serving the communication needs of the mobile computing
user, have kept Proxim at the forefront of the wireless LAN

The Harmony Family
The Harmony 802.11b PC Card is a member of a product family
that provides a complete wirefree networking solution.
qThe Harmony Access Point Controller Model 7560
centralizes the management, security, and filtering
capabilities of a wireless LAN. The Access Point
Controller communicates with Harmony Access Points
over the Ethernet network to provide wirefree network
access for mobile clients. The Access Point Controller
can support multiple Access Points, even if each Access
Point follows a different wireless standard.
qThe Harmony Access Point is a networking bridge that
operates at Layer 2 of the OSI networking model.
Working in conjunction with a Harmony Access Point
Controller, the Access Point forwards packets between
its radio and the Ethernet network. Two models of the
Harmony Access Point are available to support either
the OpenAir or IEEE 802.11b wireless standards: the
OpenAir Access Point Model 7550 and the 802.11b
Access Point Model 8550. Note that the Harmony
Power System operates only with the 802.11b Access
Point.
qThe optional Harmony Power System Model 7562
provides remote DC power to Harmony 802.11b Access
Points over the unused pins of a twisted pair Ethernet
cable.

qThe Harmony PC Card is a wireless LAN adapter that
fits into a PCMCIA Type II slot in a laptop computer.
Two models of the Harmony PC Cards are available to
support either the OpenAir or IEEE 802.11b wireless
standards.
The Harmony 802.11b PC Card Model 8432, which includes an
integrated antenna (with built-in diversity), is shown in Figure 1.

2. Installation
This chapter describes how to install the Harmony 802.11b PC
Card and software in a computer running Windows 95, 98, 2000,
and NT.
Windows 95/98 Installation
This section describes how to install the Harmony 802.11b PC
Card in a computer running either Windows 95 or Windows 98.
Pre-installation Considerations
Before beginning the installation of a Harmony 802.11b PC
Card, confirm that you have a Windows CD or diskettes avail-
able (either Windows 95 or Windows 98, depending on the
computer’s operating system). You may be prompted to insert a
Windows CD during the installation.
If you do not have the Windows CD or diskettes, it is possible
that you already have the Windows 95 or Windows 98 installa-
tion files on your hard disk. These Windows installation files
are known as Windows Cabinet files or CAB files. The Win-
dows Cabinet files are commonly located in
C:\WINDOWS\OPTIONS\CABS.
Note:
You may need the Windows CD, diskettes, or Cabinet
files to complete the installation of the Harmony
802.11b PC Card. Proxim recommends that you do
not proceed with the installation until you have con-
firmed that you have one of these Windows 95 or
Windows 98 installation media available.

Note to Customers Who Have a Laptop Without a
CD-ROM Drive
If you are installing a Harmony 802.11b PC Card in a laptop that
does not have a CD-ROM drive, you should follow the steps
below prior to installing the Harmony software:
1. Confirm that the Windows cabinet (CAB) files are
installed on the computer. The CAB files are typically
located in C:\WINDOWS\OPTIONS\CABS\.
2. If the computer does not have the CAB files installed, copy
the WIN95 or WIN98 folder, found on the Windows
CD-ROM, to a temporary folder on the computer.
3. Copy the contents of the Harmony Installation CD-ROM to
a temporary folder on the computer. Alternatively, you
may download the Harmony software from Proxim’s Web
site at http://www.proxim.com/support/.
4. Follow the installation instructions contained in this chap-
ter. When the instructions call for either the Windows CD
or the Harmony Installation CD, direct the installation
wizard to search the temporary folders you created in Steps
#2 and 3 above.
5. When the installation is complete, remove the temporary
folders you created in Steps #2 and #3 above from the
computer’s hard drive.
