8 USING THE GILL WINDDISPLAY

The WindSonic M is designed to link directly to the Gill WindDisplay unit to provide a
complete wind speed and direction system.
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.
Important:

WindSonic M must be set for RS422 output (E2), connected as shown in
Section 7.7 Connecting to a Gill WindDisplay.
 The WindSonic M must be set for Polar Mode (M2) and 9600 Baud (B3) to
interface with the Meteorological Wind Display.

If used with a Marine NMEA 4800 Baud WindDisplay set the WindSonic M
for NMEA (M5) and 4800 Baud (B2).

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 (i.e. the factory default output setting).

A separate Heater DC or AC power supply is required for a heated
WindSonic M.
