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 AC-

powered repeater.

WIRELESS REPEATER WITH SOLAR OR AC -P O W E R 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 transmitter 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.

C OMPONENTS The Wireless Repeater includes the following components. Please be sure you have everything you need for either the AC-powered or the solar-powered model.

B A Base Cover REMOVING THE COVER OF THE AC-POWER REPEATER ✦ If you have a Solar-Powered Repeater, open the shelter door by loosening the two retainer screws with a flat-bladed screwdriver.

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).

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.

3. Apply power to the repeater. ✦ AC-Power Model Plug the AC-power adapter into the jack marked POWER, and into an AC-power outlet.Watch for the LEDs to light up (as described below).

Once the repeater is receiving and re-transmitting reliably, check your console’s reception. In test mode, the console/receiver should beep approximately every 2.5 seconds to indicate that a data packet has been received. If the console is not beeping or is beeping infrequently, reposition the repeater for better reception. Note: If necessary to overcome difficult terrain or excessive obstructions, you can add additional repeaters to boost the signal through—or carry it around—various obstacles. 4.

grounding your installation. For more information, contact your local lightning protection authority and/or refer to the following articles: ✦ MIL-HDBK-419A: Grounding, Bonding, and Shielding for Electronic Equipments and Facilities, 29 Dec 1987. ✦ National Fire Protection Association, 1997: Standard for Installation of Lightning Pro- tection Systems, 1997 ANSI/NFPA 780, National Fire Protection Association, Quincy, MA.

Mounting the Solar Power Model 1. Mount the shelter against a wall or post, or on a pipe. CAUTION: Remember to face the solar panel south in the Northern Hemisphere (or north in the Southern Hemisphere) for maximum sun exposure. ✦ Wall or Post Attach the shelter to the mounting surface in the desired location using the lag screws and 1/4" flat washers as shown below.

A DVANCED I NSTALLATIONS Daisy-Chain Installation (Multiple Repeaters) To transmit data up to one and a half miles (two and a half kilometers), or to improve reception in hilly, heavily-wooded or urban areas, you can daisychain up to 8 repeaters together. For instructions on daisy-chaining multiple repeaters, see below; for instructions on adding multiple transmitters to the network as well, see page 12.
PAGE 11
Setting the Repeater ID Codes To set each repeater’s ID code (except the first), use the table below to set the Repeater ID dip switches: REPEATER ID CODE DIP SWITCH 1 DIP SWITCH 2 DIP SWITCH 3 A (default) B C D E F G H off off off off ON ON ON ON off off ON ON off off ON ON off ON off ON off ON off ON Note: If you have only one repeater, you do NOT need to set any Repeater ID code dip switches. However, if you have more than one repeater, use the above chart.
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 but, before you apply power to test your chosen locations, set unique ID codes for each transmitter and then set the closest repeater to each transmitter to listen to that transmitter. Note: Each transmitter in your network must have a different ID code so that its signal remains distinct and identifiable throughout the network.

✦ Combo Network - Multiple Transmitters AND Multiple Repeaters Any combination of the multiple transmitter network on page 12 and the daisy-chain network on page 10. Notice in this example how the data all flows in one direction; it enters the network at a point somewhere upstream and exits the network somewhere downstream.

5. Turn off the “farthest” transmitter and then add the second farthest transmitter (and its receiver) to your network. Check the reception of that second signal at each point. The goal is to make sure that your network is functioning properly at every stage so that if, at some point, you add a transmitter, repeater, or receiver that is either malfunctioning or poorly positioned, you will know immediately. 6. Add additional transmitter/receiver pairs one at a time, making sure to test only one signal (i.e.
