The Wireless Repeater receives data from a Wireless Weather Station sensor
array and re-transmits it to the console. The repeater serves to extend the
transmission range and improve reception between the sensor array’s
transmit-
ter
and the console’s
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
net-
work
of weather stations by linking the chain of repeaters to up to 8 different
wireless stations.
This manual lays out the 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 ACpowered repeater.

NSTALLATION
If you have just one sensor array (with 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. 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 have changed the Transmitter ID code to one of the 7 other optional dip
switch settings, you need to set the repeater to listen for that ID code. To do so,
first find your current transmitter settings by looking at the position of its first
three dip switches.

Then match the ON/OFF settings to a Transmitter ID code in the following
table. For example, if your transmitter’s dip switches are set to OFF, ON, OFF,
then your Transmitter ID code is 3.

Finally, set your repeater to listen for that transmitter signal by flipping the
appropriate SensorLink Tx dip switch on your repeater. For example, if your
Transmitter ID code is 3, then, use a pencil or some other pointed object to flip SensorLink Tx dip switch #3 on your repeater to ON (see the illustration below).
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, or in one of Davis’
weatherproof shelters.
Solar-Powered Repeaters
Look for a location where you can position the solar panel to receive maximum exposure to the sun’s rays:
✦
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 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.
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. To place the receiver in test mode, first apply power to the console and then flip dip switch #4 to the opposite side of wherever it was on
powerup. Refer to the Wireless Weather Station or SensorLink installation
manual for assistance if necessary.
In test mode, the transmitter’s indicator LED will flash to indicate that the
sensor unit is transmitting and the receiver will beep whenever it receives
data from the transmitter (approximately every 2.5 seconds if the signal is
within range).
2. Temporarily place the repeater where you plan to mount it.
