NSTALLATION MANUAL
The SensorLink Transmitter (#7610) and SensorLink Receiver (#7611) are
designed to work with Davis Instruments’ Weather Monitor II® and the
Weather Wizard III
sors and console up to 400 feet (120 m). The SensorLink Transmitter/Receiver
pair takes the place of the junction box and cable that would normally connect
the outdoor sensors to the display console. The outdoor sensors connect to the
transmitter while the display console connects to the receiver.
One transmitter can send data to any number of Monitor II or Wizard III consoles, providing the console contains an receiver. The transmitter/receiver
communicate on one of 8 different ID codes set by the user. This allows multiple systems to coexist in the same geographical area.
Note:
SensorLink operates on a low power frequency that does not require an FCC license.

Setting the ID Code
The wireless weather station may be set to use any of eight selectable ID codes
(the default is ID Code #1). The transmitter and receiver will only communicate with each other if they are both set to the same ID code. Use the default
setting unless you have another Davis wireless weather station operating
nearby which you want to work separately from the new system. The dip
switch settings for the eight possible codes are shown below.

To change to another ID, toggle dip switches 1, 2, and/or 3 on both the transmitter and receiver to the desired code. Remember that the transmitter and
receiver must use the same ID code in order to communicate. If, later, you ever
want to change ID codes, remember that you will need to remove and reapply
power to the console before the changes take effect.
Note: Dip switch #4 is used for testing and warnings, not for ID codes.

Silent Operating Mode
Dip switch #4 on the receiver allows you to set the console to either stay silent
or emit audible warnings. In Silent Mode , the console does not beep to indicate
problems such as low battery or poor reception. The factory sets Silent Mode
off as the default so that the console will warn you when problems occur.
When Silent Mode is OFF:
Triple Beep Warns of Transmitter Battery Problem
✦
A triple beep every 10 minutes indicates that the transmitter battery is
extremely low on power . If you hear a triple beep, replace the transmitter
battery as soon as possible to prevent possible loss of data.
Double Beep Warns of Data Reception Problem
✦
A double beep indicates that the SensorLink has not received data for at
least 30 minutes.
Dip switch #4 on the console’s receiver controls Silent Mode (see figure below).

SILENT MODE ON
SILENT MODE OFF
(Audible Warnings ON)
You can set your console to Silent Mode on or off. If you were to power up
your console with dip switch #4 in the “OFF” position (as shown above),
Silent Mode would be off and audible warnings would be on. On the other
hand, if you were to power up your console with the dip switch in the “ON”
position (not shown), Silent Mode would be on and audible warnings off.
The key is the position of dip switch #4 when you power up the console. Flipping the dip switch without repowering up the console will take you in and out
of Test Mode (see below for details), but will not change the Silent Mode setting.
Test Mode
To test signal reception at any point, simply flip the receiver’s dip switch #4 to
the opposite position from where it was when the console powered up. (You
will hear a periodic beep about every 2.5 seconds if the transmitter is within
range of the receiver and is also set to Test Mode.)
Therefore, to set the console’s operating mode (Silent Mode on or off), flip dip
switch #4 to the appropriate side and then repower the console. Then, to place
the receiver in Test Mode, simply flip the dip switch to the opposite side.

The instructions below will take you through the process requir ed to install the
transmitter and receiver.
Choosing a Location for Transmitter and Receiver
The range of the radio transmission depends on several factors. Try to position
the transmitter and the receiver as close as possible for best results.
Typical maximum ranges:
✦
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)
As you position your console, be aware of possible interference from cordless
phones and other items. To prevent interference, maintain a distance of 10 feet
between the console and the cordless phone (handset and base). Also, for best
reception, avoid positioning the console near large metallic surfaces (e.g., most
refrigerator surfaces).
Installing Transmitter and Receiver
Install the transmitter in an attic or garage, or in one of Davis’s weatherproof shelters.
1. Remove the cables from your existing junction box.
We recommend that you label the end of each cable as you disconnect it.
This will help you identify the cables when attaching them to the transmitter.
