First, power up and test just the weather station(s) and receiver(s) in your living room, garage or

office before placing the weather station(s) in their proposed outdoor location(s). This will verify

that the main components of your weather station network are functioning normally. If you

have both a console and Envoy, use the console for testing because it is easier to carry around

and has the ability to provide more data on reception diagnostics than the Envoy does. Consult

the Vantage Pro2 console manual for details on how to enter and use the diagnostic screen. If

you only have an Envoy, you will need to carry a laptop with you to read the data from the

Envoy. Select Console Diagnostics on the Reports menu to access this information. If you are

receiving 95% or more of the data packets after a few minutes of operation and your RSSI is 50

or greater while the weather station(s) and receiver(s) are adjacent, you have successfully

determined that they are working and can safely proceed to the next step in installation.

Consult the troubleshooting section of the appropriate manual if you fail to achieve these

results. Failure to receive any of the weather stations may indicate a problem with the receiver,

but you should go through the troubleshooting sections of both instruction manuals to be sure.

Next, take your weather station and receiver out to the weather station installation site and

install the weather station. Power up both units and verify that the receiver is successfully

receiving the weather station (using the same criteria as above). Force a resynch by going in

and out of the setup screen, then go into and clear the diagnostic screen on the receiver.

Check the background noise (measured only during signal acquisition). If the number is 10 or

greater, then you may have high RF interference issues outdoors. If you fail to achieve the

same success here in the outdoors that you obtained in your workspace environment or you fail

to receive any signal at all, your RF environment may be so poor that wireless technology may

not feasible in your area. Should you encounter such trouble, leave the receiver in the area for

a few hours to gather enough diagnostic information to be sure.

If successful, near the weather station, power up the first repeater in the chain, configure it to

listen to the weather station’s ID number, and place it in Test mode. You will need to

reconfigure your receiver to listen to repeater A (or whichever is first in the chain) and place it

near that repeater. Remember, unless you set the “first-in-chain” jumper, the first repeater in

the chain must be A. Clear the diagnostic screen on the receiver. When the receiver acquires

the signal from the repeater, check both the reception % and RSSI. An RSSI of less than 50 or

reception % of less than 95% while the weather station(s) and receiver(s) are adjacent indicates

the receiver is having trouble listening to the repeater. If the receiver tested well before, then

the problem may lie with the repeater. Go to the Current screen and select wind direction. The

number that appears there will be that repeater’s RSSI from the weather station while the

repeater is in Test mode. If the reception % is below 95% and/or the RSSI is below 50, this

indicates that the repeater is having trouble listening to the weather station. Should a problem

be indicated, consult the wireless repeater manual troubleshooting section to determine the

problem and course of action.

If you are able to receive the weather station through the first repeater in the chain as you just

tested, relocate the repeater to its proposed installation location. Again, on the receiver, force a

resynch and clear the diagnostic screen on the receiver. Check the background noise. (What is

shown is the receiver value, but it will be the same for the repeater if you are using a standard

repeater because they both have dipole antennas.) As before, a background noise of 10 or

more indicates high RF interference. When you acquire the repeater signal, take the RSSI

reading. Subtract the background noise value from it to get your signal to noise ratio value. If

the number is 10 or less and the reception % is 75% or greater after waiting a few minutes, then

you may confidently install the first repeater in the chain at this location.
