The Wireless Repeater receives data from any DavisTalk™ compatible transmitter and re-transmits it to any DavisTalk™ compatible receiver. The repeater
extends the transmission range and improves reception between the transmitter 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 first section, “Single Transmitter, Single Repeater Installation” on page 3,
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)” on page 10,
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 Transmitters)” on page 12,
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.

If you have just one DavisTalk™ transmitter and just one repeater, simply
follow the instructions below to install your system. If you have a more
complex setup that involves multiple repeaters or multiple transmitters within
1500' (450 m) of each other, see “Advanced Installations” on page 10.
Setting up the Repeater
The repeater is pre-set by the factory to listen for a transmitter whose ID code is
also set to the factory default (ID #1). If you have not reset your transmitter’s ID
code from the factory default, then your repeater should pick up your transmitter’s signal automatically and you can skip to “Choosing a Location” on
page 4.
If you changed the Transmitter ID code to one of the 7 other optional dipswitch settings, you need to set the repeater to listen for that ID code. To do so,
first find your current transmitter settings. For stations that do not use dipswitch settings, refer to the station installation manual. For other transmitters,
you can find the current transmitter settings by looking at the position of the
first three dip-switches.
TRANSMITTER DIP-SWITCHES
Next match the ON/OFF settings to the Transmitter ID code in your transmitter’s table. Here’s the transmitter ID code table for a typical transmitter.
TRANSMITTER
ID CODE
#1 (default) off off off
#2 off off ON
#3 off ON off
#4 off ON ON
#5 ON off off
DIP -SWITCH 1 DIP-SWITCH 2 DIP -SWITCH 3 DIP-SWITCH 4
The position
of this dipswitch is not
part of the ID
code.
#6 ON off ON
#7 ON ON off
#8 ON ON ON
Finally, set your repeater to listen for that transmitter signal by flipping the
appropriate dip-switch on your repeater to the ON position. Make sure all
other dip-switches are in the OFF position.

CAUTION: Use the larger white numbers (1-8) printed on the green board to indicate which dip-
switch belongs to which Transmitter ID code. Smaller numbers printed by default on the
switch itself may not agree.

Choosing a Location
The range of the radio transmission depends on several factors. Position the
repeater as close to the transmitter and receiver as possible for best results.
Note: Given the maximum ranges below, the repeater may need to be somewhat closer to the receiver
than to the transmitter.
Typical maximum ranges between the transmitter and the repeater:
✦ Line of Sight: 1500 feet (450 m)
✦ Through Walls and Ceilings: 700 feet (225 m)
✦ Through Trees and Foliage: 700 feet (225 m)
Typical maximum ranges between the repeater and the receiver:
✦ Line of Sight: 400 feet (120 m)
✦ Through Walls and Ceilings: 100 to 200 feet (30 to 60 m)
✦ Through Trees and Foliage: 100 to 200 feet (30 to 60 m)
AC-Powered Repeaters
Look for a sheltered location with access to an AC-power outlet. For
example, you could mount the repeater in a room or garage.
Page 4 Wireless Repeater
Solar-Powered Repeaters
Look for a location where you can position the solar panel to receive maximum 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.
✦ The solar panel should be mounted facing south in the Northern
Hemisphere and north in the Southern Hemisphere for maximum
sun exposure.
Testing Proposed Locations
Test your proposed transmitter, repeater and receiver locations to ensure
successful data transmission as follows:
1. Make sure your transmitter and receiver are in position and are operating in test
mode.
To place the transmitter in test mode, flip dip-switch #4 to “TEST” and then
power it up. Verify that the receiver is in test mode. Please refer to your
receiver manual to learn how to start the test mode.
In test mode, depending on your model, the transmitter either beeps or
flashes when it is transmitting and the receiver beeps or flashes whenever it
receives data from the transmitter (approximately every 2.5 seconds if the
signal is within range).
2. Place the repeater temporarily where you plan to mount it.
