7.7 Connecting to a Gill WindDisplay
Meteorological Display
Marine Display
The WindSonic is designed to interface with the Gill WindDisplay unit to provide a
complete wind speed and direction system.
To interface to a non NMEA WindDisplay the WindSonic is set by default for Polar
(M2) and 9600 (B3) configuration settings.
When coupled to a WindDisplay, the WindSonic can be used as supplied, however if a
fault occurs the WindDisplay may lock into the last valid reading. Re-configuring the
WindSonic 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).
Notes
1.
WindSonic Option 2 or 3 must be used set for RS422 output (E2 Mode).
2.
Use the WindSonic in the factory default mode for the Meteorological Wind
Display – i.e. do not reconfigure.
3.
If used with a Marine NMEA 9600 Baud or4800 Baud WindDisplay set the
Wind Sonic for NMEA (e.g. M5) and 9600 Baud (B3) or4800 Baud (B2).
4.
The WindDisplay can provide power to the WindSonic.
