Operational summary

The AvaLAN AW900mT module allows a user to create an ultra-long-range, wireless Ethernet network for up to 16 subscriber units per
access point.

The access point (AP) automatically scans for the best of the 12 available radio channels, encrypts Ethernet data received from the
network, and transmits it wirelessly to the correct subscriber unit (SU). The AP is constantly monitoring the network performance and
automatically changes channels if the performance is degraded due to interference. The user may manually select any of the 12 radio
channels by toggling DIP switch settings (see Page 5). It is possible to operate up to 12 APs in the same area with each AP on a different
channel. To avoid interference, the APs should be spaced at least 10 feet apart. Typically the AP is attached to the wired network via an
Ethernet cable. The AP does not have a MAC/IP address.

Any 10BaseT Ethernet client device (ECD) can be connected to an AW900mT 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. Crossover cables are never needed. Only one ECD can be attached to each SU, and xed IP addresses are recom­mended for the attached ECDs. The DIP switches on the SU should be in the default OFF setting. To avoid overloading the module’s
receiver, the SU should be placed at least 10 feet from the AP, and 100 feet spacing is recommended if using the higher gain AW11 or
AW15 antennae.

The SU does not have its own MAC/IP address. AvaLAN modules use electronic network keys that allow the user to group modules
together to form a network. Network keys are shared between modules by connecting an Ethernet cable between the RJ45 ports while
the modules are in “key exchange mode” (modules that are in “key exchange mode” display the 6 LINK QUALITY LEDs blinking sequen­tially back and forth).

To share the keys and to create the network, the user rst selects which module will be the access point (AP) by setting DIP switch 1 ON

(see Page 5 for DIP details). The other modules will function as subscriber units (SUs) and do not require any DIP settings. The user then

connects an Ethernet cable from the AP to each SU to transfer the network keys. For the AW900mT the key exchange will occur though
an Ethernet cable attached to the supplied POE injector. Key exchange will not work through a switch or hub. Once the key sharing is
complete the AP and SU change their LED displays in conrmation of the successful programming:

— The SU blinks one of the GREEN LINK QUALITY LEDs.

— The AP illuminated the LED labeled RF RX and the AP remains in “key exchange mode.”

If the user’s needs change, additional SUs can be added to the network and/or a SU can be reprogrammed to join a different network
and/or a SU can be changed into an AP and/or an AP into a SU. The modules cannot be damaged by incorrect programming. If DIP 1 is
accidentally toggled then DIP 1 can be turned back and the module still retains all the network associations it had in its previous mode

(assuming that the module had not yet successfully key exchanged with a new network). An AP can be reset by programming it as a SU

to a new AP and then turning it back into an AP again.

Continued from Page 2

SUs that have not yet received a network key boot up in “key exchange mode” and wait to receive a key. SUs that have received a
network key will boot up for 5 seconds in “key exchange mode” and will look to see if a new AP is present. If a new AP is present, then
the SU exchanges keys with the AP, otherwise the SU begins normal operation after the 5 seconds.

APs that have not yet issued network keys boot up in “key exchange mode” until they have issued network keys to at least 1 SU. Once
the AP has issued keys it will only boot up for 5 seconds in “key exchange mode.” If a SU is present during the 5 seconds, then the
AP will issue new keys to the SU and will then remain in “key exchange mode,” waiting for more SUs to be attached. Once all new

SUs have been attached, the AP must be power cycled. The AP will boot up and will enter normal operation after 5 seconds of “key

exchange mode.”

Advanced operation

Please call AvaLAN technical support at [phone] if the system topology requires:

— More than 16 subscriber units per access point for roaming/mobility applications

— Multiple access points that use the same network key for roaming/mobility

— Low packet loss rates when using broadcast or multicast Ethernet packets

NOTE: Broadcast and multicast packets (example: DHCP, UDP) are sent once and may experience losses at extended range. Unicast
packets (example: HTTP, TCP) are sent using advanced error correction and retransmission techniques to ensure delivery.

Initial setup

1) Select the module that will operate as the access point (AP) and set DIP switch 1 ON to enable AP operation.

2) Plug in the access point.
— The LINK QUALITY LEDs will blink sequentially showing that the module is hunting for a subscriber unit (SU) to share keys
— with.

3) Plug in a subscriber unit.

— The LINK QUALITY LEDs will blink sequentially showing the module is hunting for an AP to supply a network key.

4) Connect an Ethernet cable from the AP to the SU and the units will automatically exchange keys over the Ethernet cable (key
exchange will not work through a switch or hub — crossover cables are required).

— On the AP, the LINK QUALITY LEDs will still show that the module is still in “key exchange mode” and the RF TX LED will be
— lit showing that the keys exchanged successfully — ignore the other LEDs.
— On the SU, the LINK QUALITY LEDs no longer blink sequentially and will show that the module has stopped hunting and now
— has a slowly blinking pulse on one of the GREEN LINK QUALITY LEDs — ignore the other LEDs.

5) Repeat steps 3 and 4 until all SUs are successfully programmed.

6) Power cycle all modules for the new keys to take effect.

7) Deploy the modules.

Automatic frequency selection mode (DIP switches — DIP 3-8 OFF for automatic mode)

The AW900mT is designed to automatically select and continuously optimize the performance of its radio channel. The radio chan­nel is monitored to ensure it is providing low error rates necessary for successful data transmission. In the event that the error rate
rises, the access point will autonomously change to a new channel. There are 12 non-overlapping channels.

Manual frequency selection mode

The operation of the AW900mT can be restricted to a specic channel within the 900 MHz band by setting DIP switches 3-8 on

the access point as shown in the table on Page 6. The subscriber unit responds to the access point’s choice of channel and its DIP
switches have no effect and do not need to be selected.

FCC-Approved Antennas (900 MHz)

Fixed base station and mobile applications

AvaLAN Modules are pre-FCC approved for use in xed base station and mobile applications. When the antenna is mounted at least

20 cm (8”) from nearby persons, the application is considered a mobile application.

Portable applications and SAR testing

When the antenna is mounted closer than 20 cm to nearby persons, then the application is considered “portable” and requires an

additional test be performed on the nal product. This test is called the Specic Absorption Rate (SAR) testing and measures the

emissions from the module and how they affect the person.

RF exposure (This statement must be included as a CAUTION statement in OEM product manuals.)

WARNING: This equipment is approved only for mobile and base station transmitting devices. Antenna(s) used for this transmitter

must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in con­junction with any other antenna or transmitter.
