4. Insert the 3-volt lithium battery into the battery holder, matching the “+”
sign on the battery with the “+” sign on the battery holder.
5. Consult this drawing to locate the DIP switches. You will work with them
when you set the trans m itter ID.
Setting the Transmitter ID
Your Temp/Hum Station must be set to one of eight transmitter IDs. You set
the transmitter ID using DIP switches #1, 2 and 3, located on the SIM near the
battery holder. The transmitter and receiver communicate with each other only
when both are set to the same ID.
Note: DIP switch #4 is used for transmission testing and does not affect the ID.
The factory default tra nsmitte r ID set ting is ‘ 1’. Looki ng at the tab le on th e next
page, you can see that means the DIP switches are in the OFF position.
Since the ISS is included with every Wireless Vantage Pro, the console is set at
the factory to find the ISS on ‘1’. Set your Temp/Hum Station to a different
transmitter ID number.
Use a ballpoint pen or paper clip to toggle DIP switches #1, 2, and 3. The
settings for tr ansmitter IDs 1 – 8 are shown in the table on the following page:

Setting Cons ole Station ID on the Con sole
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 wor ds:
“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 Temp/Hum Station transmitter. If you don’t see it, ma ke sure the
console is within 10' of the transmitter, and verify that you se t the DIP
switches correctly. If you still don’t see it, go to “TEST mode”.
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 rec ogni ze si gna ls
on that ID as coming from a Temp/Hum 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 Temp/Hum 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 transmit-
ter ID.
Press the GRAPH key until “TEMP HUM” appears.
5. If you don’t see a 4X next to the station type, press and hold the TEMP key
then press the HI/LOW key once. A 4X should appear next to “TEMP
HUM” on the console LCD.
6. To exit Setup Mode, press and hold the DONE key.
Setting the Transmitter ID 5
Setting the Console Station ID using WeatherLink
You can also set the console ID for your Temp/Hum Station from WeatherLink
version 5.2 or later.
• In WeatherLink 5.2 and 5.3 set the station type to ISS (TEMP/HUM).
• In WeatherLink 5.4 or later se t the station type t o TEMP HUM 4x.
Note: These settings are required because of changes made to the transmitter in this
version of the Temp/Hum Station.
Viewing Current Temperature and Humidi ty
1. On the console, 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.
2. Do the same with the HUM key.
3. This confirms communication between your Temp/Hum Station and the
console. If you are not receiving the sensor readings on the console go the
the next section, “No Communication with Temp/Hum Station”.
4. Close the SIM housing cover. See page 3.
5. Go on to “Choosing a Location for the Temp/Hum Station” on page 7.
No Communicat ion with Temp/Hum Station
1. First, verify that the co nsole is po wer ed and is not in Set up Mode (exit Setup
Mode by pressing DONE key and holding it for a moment).
2. On the Temp/Hum Station, check that th e battery is properly i nstalled.
3. Walk around the room with the console, standing for a few moments in various locations to see if you are picking up signals.
4. If you don’t see readings no matter where you stand with the console, put
the transmitter on your Temp/Hum Station in TEST mode.
TEST mode
DIP switch #4 on the SIM (see illustration on page 5) 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
transmits:
• 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 11.
If the LED flashes repeatedly but your console isn’t picking up a signal
anywhere in the room, it could be related to one of the following causes:
6 Setting the Transmitter ID
1. The DIP switches were not correctly set on the Temp/Hum Station.
Review the procedure on page 4.
2. The ID was not correctly set on the console .
Review the procedure on page 5.
3. Reception is being disrupted by RF (radio frequency) interference.
4. There is a problem with the console.
See “Contacting Davis Instruments” on page 11.
Note: Remember to set the Test DIP switch OFF when you’re finished testing wireless
transmission. If it is left ON, the blinking LED will reduce battery life significantly.
Choosing a Location for the Temp/Hum Station
Consider the following factors as you choose a location:
• Do not mount the station near any source of cold or heat that might distort temperature measurements.
• The station’s radiation shield works best in a location with a steady
breeze. Mount it away from fences, buildings, trees, or other obstructions.
• Mount the station over vegetation or soil if possible.
• Do not install over or near sprinklers. The radiation shield is not
designed to protect sensors from water that is sprayed upwards.
• If mounting on a building, the preferred location is on the north side in
the Northern Hemisphere and on the south side in the Southern Hemisphere. Mount it on the side that receives the least sunlight throughout
the day.
Testing Transmission from Proposed Location
It is very important to test reception from the proposed location before
permanently mounting the Temp/Hum Station.
• Place the Temp/Hum Station at the intended mounting site, or have
someone hold it there, so y ou can walk ar ound with the console for a few
minutes.
Note: Rotating the antenna on the station and on the console may help improve
reception. Generally, for best reception the two antennas should be oriented
parallel to each other.
• Test wireless reception anywhere you might want to use or mount your
console 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 Temp/Hum Statio n now than after it h as
been mounted. Experiment.
Choosing a Location for the Temp/Hum Station 7
Mounting the Temp/Hum Station
The Temp/Hum Station can be mounted on a pole or on a ve rtic al sur face su ch
as a wooden post or wall.
Mounting on a Pole
Use a pole having an outside diameter between 1" and 1-1/4" (25 – 31 mm).
1. Slide the stud ends protruding from the top of the station through the holes
on the mounting bracket.
2. Secure the station to the mounting bracket using a #8 flat washer, #8 split
lock washer and #8 hex nut one each of the stud ends.
Tighten the hex nuts until the station is secu re on the mounting brac ket.
3. Hold the mounting bracket against the pole. Put two U-bolts around the
pole and insert the ends through the holes in the back of the mounting
bracket.
4. Secure the mounting bracket using 1/4" flat washers and 1/4" he x nuts.

Maintenance
• The ability of the radiation shield to keep fresh air flowing over the sensors will be reduced if the shield plates become dirty. Clean the surfaces
of the shield plates periodically with a damp cloth.
• Keep areas between the shield plates free of debris that may obstruct air
flow. Examples are leaves, twigs, webs, nests.
• DO NOT remove nesting insects or animals by spraying insect killer of
any kind into the radiation shield. Chemicals could easily damage the
circuitry inside your temperature/humidity station.

A Note on Securing Cables
T o 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).
Cable Clip
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.
