1Introduction
1.1 Package Contents
The Atheros AR5BAP-00030 Access Point is provided in a completely enclosed plastic
housing with two 180°swivel antennas, a power supply, and a serial cable for use in AP
software configuration. The AP Reference Design contains a single 10/100 Ethernet port.
Using this Ethernet port, a RJ-45 cable, (not provided) should be used to connect the AP
to a wired Ethernet LAN.
1.2 System Requirements
The AP uses the WindRiver Systems VxWorksreal-time operating environment,
Version 5.4. VxWorks documentation can be obtained through a license agreement with
WindRiver Systems. See www.wrs.comfor more information about VxWorks licensing.
The AP contains a small boot executive that allows the main VxWorks system software
to be downloaded using the Ethernet port over an FTP connection. The VxWorks system
software can also reside in the Flash memory of the AP, which allows booting without
the need to download VxWorks from the host PC over an FTP connection. A
configuration file is created in Flash memory to store user configurable parameters such
as WEP keys. A terminal or PC with a serial interface and an Ethernet connection is
required to perform the initial VxWorks system software loading operation as well as AP
configuration. A freeware FTP server (“a-ftp.exe”) is included on the Atheros
distribution CD in the \utils directory.

•The RS-232 serial interface is capable of 115 kbps operation, and is provided for
the purpose of configuring the AP through a terminal interface and connectivity to
other external devices such as analog modems. The AP software provides a
selectable serial interface data format to allow selection of the number of start,
stop, data, and parity bits. By default the serial interface is set to 9600 baud, 8
data bits, 1 stop bit, and no parity. Use the serial cable provided by Atheros to
attach to a terminal or PC for AP configuration.
•The RJ-45 Ethernet jack is provided for 10/100 Mbps connectivity to a wired
Ethernet LAN. The Ethernet subsystem is based on a single chip 10/100 Mbps
integrated PCI Ethernet Media Access Controller (MAC) + PHY (DP83815) from
National Semiconductor Corporation.
•An on-board MAX6713 reset circuit provides reset to processor, memory, and
PCI devices. A manual push-button reset option provides easy generation of the
reset signal without cycling power to the AP. A 3.3 V power supply is provided
to power the AP.
•A 3.3 V power supply is provided and is plugged into the power supply connector
of the AP.
Installation Note:
•To ensure compliance with FCC RF exposure requirements, the antenna used for
this device must be installed to provide a separation distance of at least 20 cm
from all persons.

2.3 AP Network Attachment and Configuration
AP Network Configuration and Network Boot
Figure 1 shows an example connection of the AP to a Host PC (HPC). Follow these steps
to establish the physical connections:
1. Plug the serial cable from the AP RS-232 serial interface to the HPC serial COM
port.
2. Connect the AP Ethernet port to the HPC Ethernet card through the Ethernet
hub/switch or an Ethernet crossover cable. An Ethernet switch/hub or crossover
cable is not included with the Atheros AP Reference Design.
3. Plug in the 3.3 V power supply adapter (provided by Atheros) to the AP power
supply connector.
Figure 1 –Connection Between AP and Host PC
At this point, the HPC needs the following configuration steps in order to control the AP:
1. From the Start menu, choose Settings and open the Network and Dial-up
Connections window.
2. Right-click on the Local Area Connection icon, which belongs to the Ethernet
controller that is connected to the AP and select Properties.

4. Configure the IP address for the Ethernet connection in the Internet Protocol
(TCP/IP) Properties window. Click OK to continue, and close Local Area
Connection Properties. Note that this IP address is used by the AP to access the
VxWorks files stored on the HPC using the Ethernet connection.

5. The AP uses File Transfer Protocol (FTP) to download the VxWorks image from
the HPC. A freeware FTP software package is included on the Atheros
distribution CD in the \utils directory. Make sure there is no other FTP program
such as Internet Information Service (IIS) running on the HPC. Double-click
a-ftp.exe under the \utils folder in the distribution CD to start the FTP server.
This utility runs in the background to perform the required data transfer between
the AP and HPC.
6. The HPC is ready to control the AP through the serial interface. A terminal
program such as HyperTerminal needs to run on the HPC. To launch
HyperTerminal, go to the Start menu, select Programs, Accessories,
Communications, and HyperTerminal.

9. Set COM port settings to 9600 Bits per second, 8 Data bits, None Parity,
1 Stop bits, and no Flow control. Click OK, and plug the AP power supply into
the power source to start the connection.
10. An auto-boot message appears on HyperTerminal a few seconds after the AP is
connected to the power source. Press any key to stop the auto-boot process and
follow Section 3.1.1 to load the VxWorks file over the Ethernet connection, or
Section 3.1.2 to load the VxWorks file from Flash memory.
2.3.1 Booting VxWorks From the Ethernet Connection to the HPC
Follow these steps to configure the AP to boot VxWorks from the Ethernet:
1. Type “c” at the command prompt to configure the AP.
2. Follow the Boot from Ethernet settings described in Table 2 to enter the
parameters in the configuration steps.

2.4 Configuring the AP
When the VxWorks system software is loaded, the AP has to be configured to set some
options such as the channel frequency and Service Set Identifier (SSID). This can be
done in two ways, either through a web browser with access to the built-in AP web
server, or by issuing commands through the serial port command line interface (CLI).
2.4.1 Web Browser
The following procedures show the steps to configure the channel frequency and SSID
using a web browser:
1. Launch a web browser (Netscape Navigator or Internet Explorer are examples of
commonly used web browsers) from the Host PC or other PC on the same IP
subnet as the AP, and enter the IP address that is assigned to the AP as the URL.
This is the “inet on ethernet (e)” value specified during the configuration step in
Section 3.1.1 or Section 3.1.2. The Access Point Web Server page appears.
