7. USING WITH THE GILL WINDDISPLAY
The WindObserver II is designed to link directly to the Gill WindDisplay unit to provide a
complete wind speed and direction system.
When coupled to a WindDisplay, the WindObserver II can be used as supplied,
however if a fault occurs, the WindDisplay may lock into the last valid reading. Re-
configuring the Wind Observer to Fixed Field Output (O2) will ensure that any fault
is flagged on the WindDisplay.
After coupling to a WindDisplay, the Wind Speed units and the Averaging period can be
selected using the WindDisplay controls. See the WindDisplay User Manual.
Note that although the WindDisplay can display wind speed in various units, these are
calculated within the WindDisplay. The data coming to the WindDisplay must be in
metres/sec (the factory default output setting).
Figure 3 WindDisplay
The WindDisplay has been designed to provide anemometer power (approximately 15V
@40mA).
If the WindObserver II has a de-icing heater fitted, this will need a separate power supply.
(See Section 6.6 ).
NOTE:- If the WindDisplay is configured for NMEA mode then the WindObserver
II must also be configured for NMEA mode and 4800-baud operation (configuration
settings M5 and B2).
