PAGE 3Technical support (650) 384-0000 www.avalanwireless.comUser’s Manual AW2400mTROperational summaryThe AW2400mTR Radio Module allows the user to create a long-range, wireless Ethernet network with up to 16 subscriber units per access point. The congu-ration may include any combination of AW2400mTR, AW2400xTR, AW2400iTR and AW2400xTP radios. Conguring a wireless link with the AW2400mTR 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 manually set or allowed to change automatically. • 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. AW2400mTR radios may be congured by two different methods. They may be con-nected to a computer that will run a web browser, setting parameters via their built-in browser interfaces. They may also be programmed via the “easy key” meth-od using the DIP switches and LEDs on the module. The access point (AP) automatically scans for the best of the 29 available radio fre-quency 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 or 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 AW2400mTR subscriber unit. Each SU encrypts Ethernet traf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 continuous Ethernet cable.
AW2400mTR User’s ManualPAGE 4Technical support (650) 384-0000 www.avalanwireless.comEvaluation Kit ContentsThe AW2400mSPI-EVAL 2.4 GHz Wireless Ethernet Module Evaluation Kit contains two each of the following items:• AW2400mSPI Wireless Ethernet Modules• AW2-2400 Omnidirectional Antennas• AW-P8 Antenna to Radio Connectors• AW-POE Power Over Ethernet Injectors• AW-12VPS 12 Volt Power SuppliesAdditional quantities of any of these components may be purchased from AvaLAN Wireless or our distributors.To power up a radio module, connect the antenna via the pigtail cable provided. Connect an Ethernet cable to the RJ-45 jack on the module. Power may be sup-plied to the module using the 12 VDC wall hanger power supply either through the Ethernet cable using the POE or directly into the P5 jack on the module.Provide some physical separation between two radio modules — at least ve feet. If their antennas are in close proximity, the module radio receivers will be over-loaded, causing degredation in the bit error rate and slower link performance.

AW2400mTR User’s ManualPAGE 6Technical support (650) 384-0000 www.avalanwireless.comBrowser Interface Conguration1. Digital conguration is done by means of the AW2400mTR’s built in browser interface. It should be powered on and connected at least temporarily to a network containing a computer that can run a conventional web browser. 2. Download the AvaLAN IP Discovery Utility from our website and extract ipnder.exe from the zip archive, placing it on your desktop or in a convenient folder.http://www.avalanwireless.com/ipnder/ipnder.zipNote that this utility only runs on MS Windows, not linux or MAC. If you must use a non-Windows computer for conguration, make sure your subnet mask allows your computer to see 192.168.17.17. Connect to that default IP address with your web browser, continuing the setup procedure with step 6.3. Run the IP Discovery Utility, ipnder.exe and you should see a window similar to this:The AW2400mTR should appear in the list at the default IP address of 192.168.17.17. If it does not, click “Search” to regenerate the list. If it still does not appear, you have a connection issue and need to re-examine the cabling or you may have a rewall issue on your computer.4. Double click the list item that refers to the AW2400mTR being congured. You should see a second window that is similar to this:The information on the left is the current status of the radio, while the boxes on the right al-low you to change it. It is important that the IP address of the AW2400mTR is in the same sub-net as your computer. For example, if the subnet mask is 255.255.255.0 ( a class C network), the rst three number groups of the IP address must match. Choose your desired parameters and click “Apply.”
PAGE 7Technical support (650) 384-0000 www.avalanwireless.comUser’s Manual AW2400mTR7. The admin page has sections similar to the login page showing radio statistics and device information plus it adds several new sections. The Device Settings section allows setting the network information and choosing an RF frequency channel. The default is to allow the radio to choose its own frequency based on minimizing interference. If you set a xed channel, make sure the AP and all SUs use the same one. References to DIPs on this and the next web page refer to the DIP switches on the module that are used in the “easy key” method of con-guration and may be ignored when using the browser method.If you scroll down in the Admin browser page, you will come to three more sections:• A graphical spectrum analyzer display that may help you to select radio channels that avoid interference• A section to be used if an update to the AW2400mTR’s rmware is required• An Advanced Links section with a dire warning about advanced users only.5. Make note of the chosen IP address and password, then click “Go to Device Web Page.” This will cause your default web browser to launch with the device IP address in the browser address bar. Or you may launch the browser on your own and enter the web page address manually: http://[the IP address you just set]. 6. The browser page that loads rst shows the current device information and QoS statistics and provides a login at the upper right. Log in using the password you just specied (or “pass-word” if you kept the default). If the login succeeds, you will see an admin page similar to this:
AW2400mTR User’s ManualPAGE 8Technical support (650) 384-0000 www.avalanwireless.com8. On the Advanced Admin page, set the parameters as follows:• Choose Device Type: Access Point or Subscriber Unit.• For Subscriber Units, assign unique ID numbers in numeric order from 1 to 63.• For an Access Point, enter the number of Subscriber Units that will be communicating with it. • Click the box labeled “Enable User Specied Keys.”• Choose an 8-digit hex (0-9 and A-F) Network Name that will be common among the AP and its SUs and enter it. The hyphen is required.• Choose a 32-digit hex encryption key and enter it. Again, the hyphens are required. This key must match between the AP and the SU so make a note of it as well. After entering the parameters, click the “Apply” button to save them to the module.9. When all of the radios are keyed and operating, connect them to your network and Ethernet devices as desired and cycle the radio module’s power to begin normal operation. Now, brows-er management of the SUs can be performed over the wireless network. Note: avoid plugging actively linked radios into the same switch because this will corrupt its routing table and may cause network problems just as if you had plugged a CAT5 cable directly between two ports of a switch.Despite the warning, you will need to click the “Advanced Admin” button in order to set the device type, ID and encryption key. You should then see a page similar to this:

AW2400mTR User’s ManualPAGE 10Technical support (650) 384-0000 www.avalanwireless.com“Easy Key” CongurationIn most cases, the browser interface is a better choice for conguring the modules. But they also can be congured as a point-to-point bridge or a point-to-multipoint group using the DIP switches. When this method is used, the module that will oper-ate as the access point provides a unique network ID calculated from its MAC ad-dress and a unique random encryption key programmed into it during manufacture.If you do congure a set of modules this way, be aware that they will all have the factory default IP address of 192.168.1.17. If you later need access to a module via the browser interface, use the IP Finder utility, select the individual unit and give it a unique IP address.Initial Setup:1. Select the module that will operate as the access point (AP) and set its DIP switch 1 on (down). Set DIP switch 1 off (up) on the module(s) that will oper-ate as subscriber units (SUs).2. Select matching frequency channels on all modules or select automatic chan-nel selection by leaving DIP switches 3-8 off.3. Power up the AP module. Its link quality LEDs will begin blinking sequentially, showing that the module is hunting for an SU to exchange keys with.4. Power up an SU module (its DIP switch 1 is off). This module’s link quality LEDs will also begin blinking sequentially showing that it is hunting for an AP to supply a network key.5. Connect an Ethernet cable from the AP module to the SU module and the two modules will automatically exchange keys. (Do not connect through a switch or hub, but cable directly with a regular patch or crossover cable.)• On the AP module, the link quality LEDs will still blink sequentially in key exchange mode and the TX LED will light showing successful key exchange• On the SU module, the link quality LEDs will no longer blink sequentially, but one of the green link quality LEDs will slowly blink to indicate success-ful key exchange.6. Repeat steps 4 and 5 for any other SU modules to be congured to the same A P.7. disconnect the Ethernet cable and cycle power on all modules for the new keys to take effect. LED behavior should reect normal RF operation once the units are deployed.
