Operational summary

The AW900x replaces costly wiring with a wireless Ethernet bridge that can enable remote Wi-Fi access points, Ethernet pan/tilt/zoom
security cameras, VoIP phones, or Internet kiosks. AvaLAN’s product offers the ideal combination of price, range, data rate, security,
interference avoidance, quality-of-service, and ease-of-use.

The AW900x is the best solution when:

— a Broadband Ethernet drop will cost too much or is impractical to install
— guaranteed DSL-rate throughput is required (kiosks/Wi-Fi access points/PTZ cameras)
— guaranteed latency for voice or video is required (PTZ cameras/VoIP)
— Wi-Fi is too slow due to saturation or 2.4 GHz interference (airport/mall/PTZ cameras)
— ultra-low current consumption is required (1 Watt/solar powered systems)

AW900xUser’s Manual

Quick setup

1) Plug in the AW900x using the supplied injector and power adapter.

2) Connect an Ethernet cable from each AW900x to a network device.

3) Send Ethernet trafc. For troubleshooting, see Page 4.

System diagram

Each AW900x radio automatically selects the best radio channel, encrypts the Ethernet trafc, and transports the data wirelessly to its

mate. Any Ethernet device can be connected to the AW900x. The AW900x functions in place of an Ethernet cable and provides a trans­parent wireless point-to-point Ethernet cable replacement. Crossover cables are not necessary as the AW900x automatically senses
the device (client or switch).

Troubleshooting

See the online installation tutorial and FAQ at www.avalanwireless.com.

No Power LED

Check the power connections.

No Radio Link LED

The radio is looking for its matched partner. If both units are powered up and the Power LEDs are active, they may be too far away
to create the radio connection. Try other locations that may have a less obstructed path or try to reorient the antennae. Yagi type
antennae get their best range when they are oriented to point directly at each other with the antenna elements oriented in the
same place (eg. vertically or horizontally).

Radio LINK LED is on but Link Quality Indicator is low

The units may be too far away to create a good radio connection. Try other locations that may have a less obstructed path, or try to
reorient the antennae.

No Ethernet LINK LED

Check your network connections.

Installing multiple systems in close proximity

See the online installation tutorial and FAQ at www.avalanwireless.com

Still not working?

Temporarily use an Ethernet cable to see if the network is working over a wired connection. If an Ethernet cable does not work
then the problem is with the network.

Advanced settings

Automatic frequency selection mode (DIP switches — all OFF for automatic mode)

The AW900x 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 radio transmission. In the event that the error rate
rises, the AW900x will autonomously change to a new channel. There are 12 non-overlapping channels.

Manual frequency selection mode

To restrict the operation of the AW900x to a subset of the 902-928 band, the user may activate a manual selection mode that allows
the radio to automatically choose the best channel within a grouped subset of the 12 available channels. This is enabled by the 8
position DIP switch on the master unit. These settings allow the AW900x to operate on the optimal channel in one of three subsets,
LOW 4, MID 4, or HIGH 4. The DIP switch settings are:

Or, the user may wish to select a specic channel. This can be done by setting DIP switches 5-8 as shown in the table below (turn
DIP 2 Off / 3 Off).

Site survey mode (DIP switch 4 — default is OFF for normal operation)

In this mode, the AW900x can perform a site survey. With this mode activated, the radios send and receive at 100 percent capac­ity by transceiving self-generated simulated data. The installer can monitor the Link Quality display to assess channel quality while
optimizing antennae orientation. The installer can manually select each channel to evaluate performance and identify the best
channels for operation. By identifying channels with poor performance it is possible to identify possible interferers and use “manual

frequency selection mode” to avoid portions of the band or select a xed operating frequency.

Note: Ethernet trafc does not get transported while the radios are in this mode.

Power save mode (DIP switch 1 — default is OFF for normal LED display)

In this mode, the display LEDs can be turned off for low power applications (solar).
