The Wireless Repeater receives data from any DavisTalk™ compatible trans-
mitter and re-transmits it to any DavisTalk™ compatible receiver. The repeater
extends the transmission range and improves reception between the transmit-
ter and the receiver.
Each repeater has a transmitting and receiving range of between 100' to 1500'
(30 to 450 m) depending upon the terrain. The repeater can listen for up to 8
different transmitter signals and can pass those signals on to another repeater
or to any number of receivers.
Note: The Wireless Repeater operates on a low power frequency that does not require an FCC license.
The repeater's flexibility allows you to put together your weather system in a
number of different ways. The most common setup is to install the repeater in
between a transmitter and a receiver to improve reception. Another possibility
is to install a chain of up to 8 repeaters to carry the transmitter's signal over a
longer distance, or around obstacles. And a third option is to establish a
network of weather stations by linking the chain of repeaters to up to 8 different
wireless stations.
This manual describes three different setup options in separate sections based
on how many repeaters and transmitters you plan to install.
The fi r st section, "Single T ransmitter , Single Repeater Installation
discusses the most common and simplest installation—that of one transmitter,
one repeater and one or more receivers.
The second section,
"Daisy - Chain Installation (Multiple Repeaters)
discusses daisy
-chaining up to 8 repeaters in succession to increase the range
between a single transmitter and one or more receivers.
And the third section,
"Network Installation (Multiple T
discusses setting up a complex network of transmitters, repeaters, and receivers.
These setup instructions apply whether you have a solar-powered or an
AC-powered repeater.

Smaller numbers printed by default on the switch itself may not agree. EPEATER SWITCHES TO ELECT RANSMITTER Choosing a Location The range of the radio transmission depends on several factors.

  • Page 5: Testing Proposed Locations

    Solar-Powered Repeaters Look for a location where you can position the solar panel to receive maxi- mum exposure to the sun’s rays as follows: The solar panel works best when the surface of the panel receives full sunlight. Mount the panel away from fences, buildings, trees or other obstructions that may cast shadows over the panel.

  • Page 12 Network Installation (Multiple Transmitters) If you have two or more transmitters in your network, follow the instructions as if for a multiple repeater installation. Before you apply power to test your chosen locations, set unique ID codes for each transmitter and then set the clos- est repeater to each transmitter to listen to that transmitter.
  • Page 13 Combo Network - Multiple T ransmitters AND Multiple Repeaters A Combo Network can have any combinations of the multiple transmitter network on page 12 and the daisy-chain network on page 10. In the example below, the data all flows in one direction; it enters the net- work at a point somewhere upstream and exits the network somewhere downstream.
