ID
Each wireless transmitting station must be set to one of eight transmitter IDs.
DIP switches #1, 2 and 3 on the SIM allow you to control the ID — the “chan-
nel” the station will transmit on. (DIP switch #4 is used for transmission test-
ing, not for transmitter ID.)
The transmitter and receiver communicate with each other only when both are set to
the same ID.
The factory default transmitter ID is ‘1’. Looking at the table below, you can see
that means the DIP switches are in the OFF position when each transmitting
station leaves the factory, whether it is an ISS, a wireless temperature station, or
another kind of station.
The ISS is included with every Wireless Vantage Pro, so the console/receiver is
set to find the ISS on ‘1’. Set your temperature station to its own ID number.
Use a ballpoint pen or paper clip to toggle DIP switches #1, 2, and 3. The set-
tings for transmitter IDs 1 – 8 are shown in the table below:
Use this table to ensure that each wireless transmitting station in your system is
broadcasting on its own transmitter ID.

SettingtheTransmitterID Page5
Setting Console/Receiver(s) to Same ID
1. Put your console into Setup Mode — press and hold the DONE key and press the
DOWN arrow key.
The console will show you Screen 1: Transmitters. You should see the words:
“RECEIVING FROM...” and “STATION NO.” followed by the transmitter
IDs that your console detects. One of these should be the ID number you just
set on the temperature station transmitter. If you don’t see it, make sure the
console is within 10' of the transmitter, and verify that you set the DIP
switches correctly. If you still don’t see it, go to “TEST mode” on the next
page.
2. Press the DONE key to move on to Screen 2: Selecting Transmitters.
Setup Mode – Screen 2 is where you will set the console to recognize signals
on that ID as coming from a temperature station.
3. Press the LEFT or RIGHT arrow key, or the STATION key, to scroll through transmitter
IDs.
When you see the ID you chose for the temperature station, use the UP or
DOWN arrow keys to activate reception of that ID code. Make sure the
screen shows “ON”.
4. Press the GRAPH key to change the type of station assigned to that transmitter ID.
Press the GRAPH key until the word “TEMP” appears.
5. To exit Setup Mode, press and hold the DONE key.
(See the Vantage Pro User’s Manual & Setup Guide : “Setup Mode – Screen 2:
Selecting Transmitters.”)
Viewing Current Temperature
Press the TEMP key until you see an ‘outside’ temperature displayed on the
console screen, with the correct Station No. displayed above or below it. This
confirms communication between your temperature station and the console —
go on to “Choosing a Location for the Wireless Temperature Station” on page 6.
If You Do Not See Current Values from the Correct Station No.
First, verify that the console/receiver is powered and is not in Setup Mode (exit
Setup Mode by pressing DONE key and holding it for a moment). Then, on the
temperature station, check that the battery is properly installed. Walk around
the room with the console, standing for a few moments in various locations to
see if you are picking up signals.
If you don’t see readings no matter where you stand with the console, put the
transmitter in TEST mode.

TEST mode
DIP switch #4 on the SIM (see illustration on page 4) is the TEST DIP-switch.
Switch it to the ON position using a ball-point pen or paper clip. This puts the
transmitter in Test Mode. An LED indicator light will flash each time it trans-
mits:
✦
The LED will immediately flash once to show that the light itself functions.
✦
Then it will flash each time the transmitter broadcasts a signal, which should be
every 10 seconds.
If the LED flashes only once and then remains dark, there is a problem with the
transmitter. See “Contacting Davis Instruments” on page 10.
If the LED flashes repeatedly but your console isn’t picking up a signal any-
where in the room, it could be related to one of the following causes:
1. The DIP switches were not correctly set on the transmitter.
Review the procedure on page 4.
2. The ID was not correctly set on the console/receiver.
Review the procedure on page 5.
3. Reception is being disrupted by RF (radio frequency) interference.
4. There is a problem with the console/receiver.
See “Contacting Davis Instruments” on page 10.
Note: Remember to turn the Test DIP switch OFF when you’re finished testing wireless transmis-
sion. If it is left ON, the blinking LED will reduce battery life significantly.

Locate the station’s temperature probe where it will not be exposed to sources
of heat or cold that could distort temperature measurements.
The temperature probe is waterproof. It can be used to measure soil or water
temperature. The transmitter shelter is not waterproof.

Wireless Temp Page 6 Thursday, December 7, 2000 2:09 PM

ChoosingaLocationfortheWirelessTemperatureStation Page7
Consider these factors when locating the temperature probe to measure air
temperature:
✦
Place the probe where it will not be in direct sunlight and where it will have lim-
ited exposure to reflected sunlight.
If possible, place the sensor at least 5' (1.5 m) from any surface which is
exposed to direct sunlight.
✦
Limit the probe’s exposure to night sky.
The temperature probe will cool down faster than the surrounding air.
Inaccurate temperature readings from exposure to sunlight and night sky are
due to radiation effects. These effects can be minimized by placing your tem-
perature probe in a Radiation Shield #7714 or Fan-Aspirated Radiation
Shield #7750/7755 .
The following factors should be considered whether your temperature probe is
inside a radiation shield or not:
✦
If placing the probe on the outside of a building, a good location is under the
eaves on the north side of the building. (In the Southern Hemisphere, the south
side of a building is preferable.)
✦
Place the probe at least 10' (3 m) away from lights or lamps.
✦ Place the probe at least 5' (1.5 m) from chimneys and exhaust vents.
✦
Try not to run sensor cable across large metal objects such as aluminum siding.
Range of Wireless Transmission
The range of wireless transmission depends on many factors. For the best
reception, position the transmitter shelter and your console/receiver as close
together as possible.
Range is up to 800' (250 m) in the line of sight, under optimal conditions. Typi-
cal range under most conditions is 150' to 500' (45 to 150 m), but this may be
reduced by walls, ceilings, trees, or foliage. Radio-frequency interference (RF)
can also reduce transmission distance. Cordless phones and ham radios are
common examples of RF interference.
A metal roof or other large metal structure can interfere with the signal (alumi-
num siding, a furnace with metal ducts, and your refrigerator are examples).
Sometimes transmission between wireless units is obscured by something you
cannot identify, or by some obstacle that you can’t work around. If necessary,
consider using Wireless Repeater #7624 or #7625 to strengthen the signal or
increase the distance between the transmitter and the console/receiver.

TESTING TRANSMISSION FROM PROPOSED LOCATION
It is very important to test reception from the proposed location before perma-
nently mounting the temperature station.
Place the shelter at the intended mounting site, or have someone hold it there,
so you can walk around with the console/receiver for a few minutes. Rotating
the antenna may help to improve reception.
Test wireless reception anywhere you might want to use or mount your con-
sole/receiver now or in the future. Take your time. If you aren’t picking up
strong signals where you intend to place your console, better to move the shel-
ter now than after it has been mounted. Experiment.
If you have irregular terrain in the area, it may interfere with the signal. For
example, if the transmitter is mounted downhill from the console/receiver, the
ground may block a wide angle of the transmitted signal.
MOUNTING THE WIRELESS TEMPERATURE STATION
Mounting on a Pole
1. While holding the shelter against the pole, place a U-bolt around the pole and
through the two holes on at the top of the shelter.
2. Place a flat washer, a lock washer and a hex nut on each of the bolt ends.

A NOTE ON SECURING CABLES
To prevent fraying or cutting of cables, secure them so they will not whip about
in the wind. Secure a cable to a metal pole by wrapping electrical tape around
them both. Make sure cables are secure by placing clips or ties approximately
every 3 – 5' (1 – 1.6 m).
Note:Do not use metal staples or a staple gun to secure cables. Metal staples—especially when
installed with a staple gun—have a tendency to cut the cables.
