Thank you for your purchase of the AW-D2-900 wireless Ethernet dome. The AvaLAN wireless radio functions in place of an Ethernet
cable and provides a transparent wireless point-to-point Ethernet cable replacement.
If you have any questions when conguring your AvaLAN system, please send an e-mail to support@avalanwireless.com.
For a live technician, please call technical support at (650) 384-0000.

Initial setup
CAMERA
1) Set up your network camera while attached to a network. Please refer to the manufacturer’s instructions provided with the
camera.
2) Check that the video from the camera can be viewed on a networked PC.
3) To optimize the camera for use over a wireless link, please see the camera performance FAQ at www.avalanwireless.com/support.
DOME
1) Install the Dotworkz D2 dome housing. Please contact Dotworkz for installation support
on the dome housing [www.dotworkz.com; (866) 575-4689].
2) Mount the network camera within the dome housing according to Dotworkz’ instructions.
3) Attach the antenna to the dome.
WIRELESS SETUP
1) Install the AW900x.
2) Attach the antenna to the AW900x (see Appendix A for polarization guide on Page 7).
3) Attach the white power injector to the end of the Ethernet cable.
4) Attach the 120 VAC to 12 VDC power supply to the white power injector.
5) Connect an Ethernet cable from the injector to the network (or directly to a PC).
6) The AvaLAN radios automatically select the best radio channel, encrypt the Ethernet data, and transport the data wirelessly to its
mate.
7) Use an Internet browser on a networked PC to view the video from the camera. Make sure the subnet/IP addresses of the PC and
the camera are compatible.
8) For radio/network troubleshooting, see Page 4.

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 reorienting the antennas. 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 plane (i.e. vertically or horizontally).
Radio LINK LED 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
reorienting the antennas.
No Ethernet LINK LED
Check your network connections.

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:

Continued from Page 4
Or the user may wish to select a specic channel. This can be done by setting DIP switches 5 through 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 trafc 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 lower power applications (i.e. solar).
