The Bridge comes with a mounting cradle that allows the Bridge to be installed on a vertical
surface, such as a wall (see
supplied) excessively to avoid damaging the cradle. When mounting the Bridge vertically, attach
the cradle to the vertical surface, and then insert the Bridge into the cradle.

The heavy-duty version of the Bridge is supplied in a Deutsch EEC-325X4B enclosure and is
available in both sealed and unsealed versions. The heavy-duty Bridge supports SAE J1455
power specifications (+4.5 to 36 VDC).
Figure 5 identifies the components on the Bridge in its heavy-duty packaging. These
components include:
An external antenna.
A Deutsch 12-pin DTM13-12PA-R008 receptacle for power and signal connections.
A Reset switch.
Four indicator Light Emitting Diodes (LEDs) on the top of the Bridge.
The Heavy-Duty Bridge has four indicator LEDs for viewing its current status and connections
(see Figure 5). These indicators allow for monitoring and troubleshooting of the Bridge. They
also indicate the Bridge’s power-up status, link, connection, and data-activity status. Table 3
describes the status of the indicator LEDs.
You can mount the Bridge on a flat surface, such as a desk or table, or on a vertical surface,
such as a wall. It can also be mounted on the ceiling. If you mount the Bridge vertically, use the
supplied mounting cradle previously described.
Choosing a good location for the Bridge is important because it affects the reliability of the
wireless link. The most important considerations are distance from the Access Point and
clearance from obstacles.
When considering a location for installing the Bridge, ensure that it:
Provides sufficient ventilation around the Bridge.
Allows easy access to disconnect the Bridge from the AC wall outlet if necessary.
Does not expose the Bridge to excessive heat, humidity, vibration, or dust.
Conforms to local regulations.
Because radio waves travel in a straight line, the location where you will install the Bridge must
provide a clear path to the Access Point that is free of major obstacles. The effects of obstacles,
both along and near the path, have a significant bearing on the travel of radio signals and can
cause both interference and signal cancellation. Consider the effects of the following common
obstacles:
Trees and large plants
A tree or large plant directly in the path can totally block the signal. With clearance
above the trees, there are usually no blocking effects.
Man-made obstacles
Square or rectangular objects, in or near the path, have rectangular surfaces that can
block and interfere with signals over and around them.
Floor
A floor can interfere with signals if the Bridge is mounted too low. Mount the Bridge so
the antenna is high enough to allow adequate clearance from the floor.
The following procedure describes how to connect the Bridge:
• Place the Bridge in a dry, clean location near the device to which it will be connected. The
location is required to have an AC power source and be within 300 feet (100 meters) of an
IEEE 802.11b/g-compliant wireless LAN Access Point with DHCP enabled. The location
should be away from transformers, heavy-duty motors, fluorescent lights, microwave ovens,
refrigerators or other equipment that could cause radio-signal interference.
Note:
Do not connect the Bridge to the intended Ethernet client at this time.
• Raise the antenna on the Bridge so it is pointing vertically.
• Connect the supplied power adapter to the Bridge and to a grounded 110/240V, 50-60Hz
AC power source.
• If your Access Point is using WEP or WPA, disable the security. You can re-enable WEP or
WPA after the Bridge has been configured.
• Connect the RJ-45 jack on the Bridge’s Ethernet cable to an RJ-45 jack on your Ethernet-
After you verify that the indicator LEDs have gone through their power-up sequence, start the
configuration application for your Access Point (your Access Point manual should describe this
procedure). Then go the appropriate screen in the application and perform the following steps:

manufacturers. In the following steps, there are suggested screen names where
you might find the Access Point settings required to operate the Bridge. The
screens in your Access Point’s configuration application may differ from those
mentioned below. Refer to the documentation that came with your Access Point
to locate the appropriate screens where these settings can be accessed.
Go to the Wireless Settings or equivalent screen in your Access Point’s configuration
application that shows the Access Point’s SSID. Record the SSID in Table 4 (on
page 20). You will need this information to configure the Bridge.
Go to the Wireless Settings, Security, Encryption, or equivalent screen in your
Access Point’s configuration application that shows the WEP/WPA setting. If WEP or
WPA is enabled, disable it (you can enable the AP security after the Bridge has been
configured).
Go to the Attached Devices or equivalent screen in your Access Point’s configuration
application that lists the IP addresses of devices attached to the Access Point. Find
the IP address for the Bridge and record it in Table 4 (on page 20). You will need it to
access the Bridge with the Airborne Control Center (ACC).
If you do not see the Bridge as an attached device, refresh the configuration

software (see page 25XX) to help determine the Bridge’s IP address.
•Verify the MAC Address
Go to the Attached Devices or equivalent screen in your Access Point’s configuration
application that lists the MAC addresses of attached devices. Verify that the MAC
address shown for the Bridge matches the one on the label on the back of the
Bridge.
•Verify the Dynamic Host Configuration Protocol (DHCP) Name
Go to the Router Status or equivalent screen in your Access Point’s configuration
application that shows the Bridge’s DHCP client name. Verify that this name
matches the last six characters in the Bridge’s MAC address (AIRBORNExxxxxx) on
the label on the back of the Bridge.

Access Point’s SSID
Bridge’s IP address
You can also use the device discovery feature of the Airborne Control Center
If the Bridge is unable to obtain an IP address through DHCP, after the
Note:
acquire limit is exceeded (150 seconds) the bridge will install the fallback
IP address (192.168.10.1) and subnet (255.255.255.0).
The bridge can be accessed using this address, after DHCP fails, by the
attached host using a different IP address in the same subnet
(192.168.10.8).
When the Bridge is powered-up, the indicator LEDs at the top of the Bridge will indicate the
status of the Bridge. See Table 2 on page 11 for standard packaging, or Table 3 on page 15 for
Heavy-Duty packaging.
If the LEDs indicate a problem with a wired or wireless connection, remove the power source
from the Bridge, wait a few seconds, and re-apply power. If the LEDs still do not behave
appropriately, see the guidelines in Table 11 on page 52.
Other Access Points in the area may interfere with the Bridge’s ability to
Note:
associate with your chosen Access Point (the Bridge will try to associate with
the first available “best-quality” AP). If you encounter difficulties with connecting
to your chosen AP, either remove power from these Access Points or move to
an isolated location and perform the setup shown in Figure 1 on page 3.
The WPA and LEAP software modules provide advanced security configuration and
communication services required by today’s enterprise-class deployments.
Please refer to IEEE standard 802.1x 2001 (section 4) and IEEE standard 802.11i 2004 (section
4) for additional information.
System Requirements
Both WPA and LEAP require radio firmware version 1.1.1.111.8.4 or later. The AP requires
WPA support. LEAP must be supported in the AP or a separate authentication server.
Computer Resource Requirements
WPA-PSK
In order to function properly, an Access Point that supports WPA-PSK must be available. The
WPA-PSK passphrase installed on the Access Point must match the passphrase configured on
the bridge.
LEAP
In order to function properly, a RADIUS server configured for LEAP containing
usernames/passwords, and an Access Point that supports LEAP, must be available. The
RADIUS server username and password must match the user-leap and pw-leap command
values configured on the bridge.
The blank character (space) may not be included in a passphrase or LEAP
Note:
password.
System Implementation Considerations
The bridge must be in infrastructure mode for WPA-PSK or LEAP to operate properly. A bridge
configured for WPA-PSK requires a connection to an AP with WPA-PSK enabled. A bridge
configured for LEAP requires a connection to an AP with LEAP enabled and connected to a
RADIUS server to provide authentication.
Until the bridge is authenticated by either the WPA-PSK enabled AP or the RADIUS server, no
IP network communication can proceed.
Symptoms of an unauthenticated client include:
A bridge configured for DHCP will not obtain host configuration from the DHCP server;

encounter a problem using the AirborneDirect™ Ethernet Bridge.
TROUBLESHOOTING SUGGESTIONS
Table 10. Troubleshooting Suggestions
The Bridge cannot find the Access
Point.
The Access Point cannot find the
Bridge.
You cannot access the Bridge’s
configuration interface via the ACC.
Verify that the Link LED is solid green. If it isn’t,
refer to “LED Troubleshooting” on the next page.
Click the Refresh button in your Access Point’s
configuration application.
If the problem remains, check the Bridge’s physical
connections. Then power-down the Bridge, power it
up, and check the power-up LED sequence
described under “XXVerifying Your ConnectionsXX” on
page XX20XX.
Make sure that there is not another AP in the area
that may be interfering with your AP.
The Bridge may be associated to another AP.
Check the Link LED on the Bridge.
If the problem remains, contact Quatech, Inc.
You may have typed the wrong IP address.
If you typed the correct IP address, your computer
may be on a different subnet than the Bridge. Be
sure the computer and Bridge are on the same
subnet of the same network.
Change the location of the Bridge to improve
reception.
If that does not help, launch the ACC, go to the
XXNetwork Settings PageXX, and be sure the SSID
matches that of the Access Point (remember the
SSID is case sensitive).

Troubleshooting
After changing the Bridge’s static IP
address, the ACC stops responding.
You used the ACC to change the
Bridge’s configuration settings, but the
new settings did not take effect.
You tried to update the firmware, but
the new firmware did not take effect.
Once the static IP address is changed and you click
Save, the Bridge switches to the new IP address
and loses connection with the ACC. To resolve this
problem, restart the ACC.
You may not have clicked the Save button on the
ACC page. Click this button after making your
changes on the page.
You uploaded an incorrect file. Go to the XXUpdate
Firmware Page
XX and check the current level. Make
sure the one you will upload has a higher (later)

Bridge has not established an IP address either
through DHCP or Static methods.
DHCP is the default method by which the unit
obtains an IP address. Your network must have a
DHCP server available when the bridge is poweredup. Most AP/Routers have a DHCP server built-in.
Enable your DHCP server and re-start the module.
Bridge has not found an Access Point with which to
associate. Be sure the Access Point you want to
use is turned on and has WEP disabled (you can
enable WEP after the Bridge has been configured).
If this does not help, be sure there are no nearby
devices causing interference. If there are, either turn
off or move the device causing the interference or
move the Bridge and Access Point to another
location.
Be sure an Ethernet device is connected to the
Bridge and that the device is turned on.
Comm LED is Red and Link LED is
Green but you are unable to pass data.

Wireless standards developed by the IEEE that specify an "over-the-air"
interface for wireless Local Area Networks. 802.11 is composed of several
standards operating in different radio frequencies.
802.11b is the international standard for wireless networking that operates in
the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a
throughput of up to 11 Mbps.
802.11g is the international standard for wireless networking that operates in
the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a
throughput of up to 54 Mbps.
An interface between a wireless network and a wired network. Access Points
can combine with a distribution system (such as Ethernet) to create multiple
radio cells (BSSs) that enable roaming throughout a facility.
A wireless network composed of only stations and no Access Point.
An IEEE 802.11 service that enables the mapping of a wireless station to the
distribution system via an Access Point.
Type of synchronization where there is no defined time relationship between
transmission of frames.
The process a station uses to announce its identify to another station.
IEEE 802.11 specifies two forms of authentication: open system and shared
key.
The amount of transmission capacity available on a network at any point in
time. Available bandwidth depends on several variables such as the rate of
data transmission speed between networked devices, network overhead,
number of users, and the type of device used to connect PCs to a network.
A set of 802.11-compliant stations that operate as a connected wireless
network.
A measurement of data transmission speed over communication lines based
on the number of bits that can be sent or received per second.
Basic Service Set Identifier. A 48-bit identifier used by all stations in a BSS in
frame headers. Usually a MAC address.
A function that determines the state of the wireless medium in an IEEE
802.11 network.
Any computer connected to a network that requests services (files, print
capability) from another member of the network.
Combines a data signal at the sending station with a higher data rate bit
sequence, which many refer to as a “chip sequence” (also known as
“processing gain”). A high processing gain increases the signal’s resistance
to interference. The minimum processing gain that the FCC allows is 10, and
most products operate under 20.

An IEEE 802.11 term that defines the process a station or Access Point uses
to notify that it is terminating an existing association.
An IEEE 802.11 station uses the distribution service to send MAC frames
across a distribution system.
General Purpose Input/Output refers to the digital I/O lines.
Same as an Access Point (usually found in public areas such as coffee shops
and airports).
Institute of Electrical and Electronic Engineers, an international organization
that develops standards for electrical technologies. The organization uses a
series of numbers, like the Dewey Decimal system in libraries, to differentiate
between the various technology families.
An IEEE 802.11-based wireless network that has no backbone infrastructure
and consists of at least two wireless stations. This type of network is often
referred to as an “Ad-Hoc network” because it can be constructed quickly
without too much planning.
A client setting providing connectivity to an Access Point. As compared to AdHoc mode, whereby PCs communicate directly with each other, clients set in
Infrastructure mode all pass data through a central Access Point. The Access
Point not only mediates wireless network traffic in the immediate
neighborhood, but also provides communication with the wired network. See
Ad-Hoc Mode and Access Point.
A software application that runs on a computer (which is attached to a LAN,
Intranet or the Internet) and using various protocols, can communicate with
the Bridge.
Lightweight Extensible Authentication Protocol developed by Cisco. LEAP
provides username/password-based authentication between a wireless client
and a RADIUS server. It is one of several protocols used with the IEEE
802.1X standard for LAN port access control.
A system of connecting PCs and other devices within the same physical
proximity for sharing resources such as Internet connections, printers, files
and drives. When Wi-Fi is used to connect the devices, the system is known
as a wireless LAN or WLAN.
One of two sub-layers that make up the Data Link Layer of the OSI reference
model. The MAC layer is responsible for moving data packets to and from
one network node to another across a shared channel.
A wireless or wired computer network that has no server or central hub or
router. All the networked PCs are equally able to act as a network server or
client, and each client computer can talk to all the other wireless computers
without having to go through an Access Point or hub. However, since there is
no central base station to monitor traffic or provide Internet access, the
various signals can collide with each other, reducing overall performance.
An operating system implementing components and services that explicitly
offer deterministic responses, and therefore allow the creation of real-time
systems. An RTOS is characterized by the richness of the TTservicesTT it
provides, the performance characteristics of those services, and the degree
that those performance characteristics can be controlled by the application
engineer (to satisfy the requirements of the application).
An identifier attached to packets sent over the wireless LAN that functions as
a "password" for joining a particular radio network (BSS). All radios and
Access Points within the same BSS must use the same SSID, or their
packets will be ignored.
A virtual terminal protocol used in the Internet, enabling users to log into a
remote host.
Temporal Key Integrity Protocol and is used in encryption. TKIP is an IEEE
802.11i standard and an enhancement to WEP security.
A device for transmitting and receiving packets between the computer and
the medium.
A commonly used protocol for establishing and maintaining communications
between applications on different computers. TCP provides full-duplex,
acknowledged, and flow-controlled service to upper-layer protocols and
applications.
A communication system of connecting PCs and other computing devices
across a large local, regional, national or international geographic area. Also
used to distinguish between phone-based data networks and Wi-Fi. Phone
networks are considered WANs and Wi-Fi networks are considered wireless
LANs.
Wi-Fi is a name for 802.11 wireless network technology.
A non-profit international association formed in 1999 to certify interoperability
of wireless LAN products based on IEEE 802.11 specification.
A security protocol for wireless LANs defined in the IEEE 802.11 standard.
WEP is designed to provide the same level of security as a wired LAN.
Also referred to as a wireless LAN. A type of Local Area Network that uses
high-frequency radio waves rather than wires to communicate between nodes
and provide network connectivity.
Wi-Fi Protected Access. It addresses all known Wired Equivalent Privacy
(WEP) vulnerabilities. WPA uses RC4 for encryption and TKIP for key
management. It includes a message integrity mechanism commonly called
Michael or MIC.
WPA-LEAP
WPA-PSK
Wi-Fi Protected Access - Light Extensible Authentication Protocol, an
implementation based on the IEEE 802.11i 2004 and IEEE 802.1X 2001
standards, which includes the LEAP protocol for initial key assignment.
Wi-Fi Protected Access - Pre-Shared Key, an implementation based on the
IEEE 802.11i 2004 and IEEE 802.1X 2001 standards, where the PSK is
