Test Mode
DIP switch #4 on the SIM (see illustration on page 6) 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, located below the jack to the right of the battery on the
SIM, will flash each time the transmitter broadcasts a signal, which should be every 2.5
seconds.
If the LED flashes only once and then remains dark, there is a problem with the
anemometer 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:
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. Interference has to
be very strong to prevent the console from receiving a signal while in the same room
as the anemometer transmitter!
4. There is a problem with the console/receiver. See “Contacting Davis Instruments” on
page 11.
Note: Remember
to
turn 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 Anemometer Transmitter
Keep the following factors in mind as you choose a location for your anemometer and
the transmitter shelter:
•
Mount the anemometer at least 4' (1.2 m) above the roofline for accurate wind
readings. As shown in the ISS manual, the anemometer can be mounted on a pole
or on a vertical surface such as a wooden post. It comes with 40' (12 m) of cable
to connect to the transmitter shelter.
•
Mount the transmitter shelter nearby, with the solar panel facing the sun. In the
Northern Hemisphere, position the transmitter shelter with solar panel facing
south, for maximum sun exposure. (In the Southern Hemisphere, position the
shelter with solar panel facing north.)
•
If you need to increase the distance between your anemometer and the transmitter
shelter, use extension cables #7876 from Davis Instruments. Please be aware that
maximum wind speed reading decreases as the total length of cable from the
anemometer to the ISS increases. If this distance is greater than 240' (73 m),
maximum wind speed may be less than 100 mph (161 kph).
Note:
Not all cables are compatible with your Vantage Pro2 system. To be sure they will work, order
extension cables from your dealer or directly from Davis Instruments.
