ROUBLESHOOTING
If you encounter an error when testing the connection, one of the following sit-
uations may exist:
✦
Serial Port Error
Make sure you have selected the correct serial port or baud rate. Use
Loopback to determine the correct serial port, if necessary (consult the
software manual for instructions).
✦
Connection Configuration Error (GroWeather only)
Make sure you have selected the correct connection type, address, and
link revision. The error message you receive may help you pinpoint the
error:
✦ “Unable to make a connection” may mean you have
selected the wrong connection type or address.
✦ A “not answering (timeout)” message may mean you have
selected the incorrect address (among other possibilities.
✦ A “not understood” or “failed CRC check” message may
mean you have selected the wrong WeatherLink revision.
✦
Station Type Error
Make sure you are using the correct software for the station to which you
are attempting to connect. For example, you cannot connect to a Weather
Monitor II
®
using the GroWeatherLink software.
✦
Power Not On
Make sure both the base and field station radio modems have power. If
power conservation is being used at the field station, check that power is
switched on at the time of test.
✦
Hardware Problem
For both the base and field stations, check that all power, WeatherLink,
and Antenna connections are correct and secure. Check that there is an
unobstructed line-of-sight path between the base and field station anten-
nas. If using directional antennas check that they are aligned (aimed at
each other) and have the same orientation (horizontal or vertical). If one
antenna is an omni and one a Yagi, the Yagi must be vertical.
