USER’S MANUAL ADDENDUM

Matched Pair Bridges

Certain AvaLAN radios are sold as matched pairs, pre-congured as a wireless Ethernet
bridge. The manual supplied with the pair does not include information about the pair
conguration, hence this addendum.

This addendum applies to these products:
AW900xTR-PAIR AW2400xTR-PAIR

AW900iTR-PAIR AW2400iTR-PAIR

AW900xTP-PAIR AW2400xTP-PAIR

The pair conguration as shipped from the factory consists of these features:

1. One unit of the pair is congured as an Access Point and the other is congured

as a Subscriber Unit.

2. The Access Point is given the IP Address 192.168.17.17.

3. The Subscriber Unit is given the IP Address 192.168.17.18.

4. User-specied encryption keys are disabled and the two radios are keyed to

each other using the “Auto-Key” method.

5. RF Channel selection is set to automatic mode.

If these conguration parameters work for you in your system, you need only to connect
antennas, power and LAN and the pair should work transparently, looking just like an
Ethernet cable.

If you need to change any of the pair’s parameters, you may use the browser interface as
described in the accompanying manual. You might need to do this if you need to set the
pair to a particular channel, or you wish to provide your own encryption keys. If the default
IP Addresses won’t work in your system, the best way to change them is by using the
ipnder utility described in the manual and downloadable from www.avalanwireless.com.

In case of diculty, you may nd additional help under the Support tab on our website or
by contacting AvaLAN Technical Support using the information in the manual.

Quick Start Guide

PROGRAMMING:

Step 1. Gather the AvaLAN radios, power supplies, 2x CAT5 cables and a computer with an RJ45

Ethernet interface.

Step 2. Connect the radios one at a time directly to the PC via an Ethernet cable. Set your computer
to an IP address of 192.168.17.1 (refer to page 6 for detailed instructions). Enter the radio’s default
IP address* of 192.168.17.17 into a web browser.

Step 3. Enter the password and click login. The default password is “password”.

Step 4. Click “advanced admin” at the bottom of the web page.

Step 5. Toggle to select the device type - Access Point or Subscriber Unit. An access point (AP) can

communicate with up to 16 Subscriber Units (SU).

• For the AP, enter the maximum number of SUs communicating with the AP.

• For each SU, set the subscriber ID incrementing from one. (Ex. 1, 2, 3, etc.)

Step 6. Enter the “Network Name” and “Encryption Key” using numbers “0-9” and characters “A-F”.
All radios in a single network must have the same “Network Name” and “Encryption Key”.

TESTING:

We recommend connecting and powering up the units on the bench before deploying in the eld.
During bench testing, keep the radios at least 10 feet apart to prevent overload of radio receivers.

Step 1. Power on all the radios with the computer wired directly to the AP.

Step 2. Use the AvaLAN IP nder utility to assign a unique IP address to each radio. (See page x)

Step 3. Open a web browser to view the operation of all the radios. (See page y)

Step 4. Perform PING ood testing to simulate network data and observe overall performance.

INSTALL:

Every installations is dierent, however radio performance is typically best at shorter distances
using directional antennae with unobstructed paths in low noise environments. It can be challenging
to determine the best approach for a unique installation. The radio’s browser interface has a link
performance statistics and a spectrum analyzer display that is helpful for troubleshooting radio
interference noise levels. (See page 9).

AW900iTR

User’s Manual

Operational Summary

The AW900iTR Radio allows the user to create a long-range, wireless Ethernet network with up to
16 subscriber units per access point. The conguration may include any combination of AW900iTR,
AW900xTR and AW900xTP radios. (Please note that older AvaLAN 900 MHz radios can exist on the
same LAN but cannot be used to form wireless links with the AW900iTR units because link encryption
protocols have changed.)

Conguring a wireless link with the AW900iTR requires the establishment of six elements:

• Each radio must know whether it is to be an access point (AP) or subscriber unit (SU).

• Each radio must have an IP address that is unique among all others on the same network.

• The AP must know how many SUs are expecting communication with it.

• The AP and any given SU must agree on which radio frequency channel they are using. This can

be ma nua lly se t or al low ed t o c han ge a u tom ati cal ly.

• The SU must be assigned a unique subscriber ID to specify which time division slot it will use
when communicating with the AP.

• The AP and any given SU must share a common 128-bit encryption key and 32-bit network name.

The access point (AP) automatically scans for the best of the 12 available radio frequency channels,
encrypts Ethernet data received from the network, and transmits it wirelessly to the correct subscriber
unit (SU). The AP is constantly monitoring the radio link and can automatically change the channel
if performance is degraded due to interference. If two AP units are very close to one another, they
may interfere if operating on adjacent frequency channels. Place them at least 10 feet apart and
manually select non-adjacent channels for their operation. Also, the SU should be placed at least 10
feet from the AP to avoid overloading the radio’s receiver.

Any 10/100 BaseT Ethernet client device (ECD) can be connected to an AW900iTR subscriber unit.
Each SU encrypts Ethernet trac received from the attached ECD and transmits the data wirelessly
to its AP. Each SU can be plugged directly into an ECD without adding drivers or loading software.
Essentially, once the AP/SU pair is congured and running, it behaves like a transparent Ethernet
cable that encrypts and then passes all trac including VLANs.

Physical Setup

1. Before placing the radio in its nal location, it may be best to perform the digital setup procedure
described in the next section.

2. Connect the AW900iTR’s RP-TNC RF connector to a suitable antenna. A 2 dBI omni-directional
dipole antenna (AW2-900) is included and is suitable for testing and general applications. Application
specic antennas are available if greater range and/or directionality is required. Choose one of our
other antenna models that can be found on our website at www.avalanwireless.com.

3. Power is provided to the unit by means of the 120 VAC to 12 VDC 0.5A wall power supply.
