Introduction
The WSD110 provides accurate digital instrumentation for
wind speed, average wind speed, apparent wind speed, true
wind speed and Velocity Made Good (VMG), apparent wind
direction, true wind direction and air temperature from several
different NMEA 0183 data sentences.
If NMEA 0183 boat speed or GPS data is available, the WSD-
110 will calculate true wind speed, true wind direction and
VMG with respect to the boat or respect to the ground.
Apparent wind speed/direction, true wind speed/direction, boat
speed and VMG data is logged to a non-volatile memory. You
can select 240 different logging periods between 2.5 seconds to
10 minutes per sample providing up to 40 days of data. Serial
logging data is output in comma delimited CSV (Excel) format.
The WSD110 displays Speed, Average Speed and Maximum
Speed up to 99.9 Knots (115 M.P.H.) in tenths, wind direction
in degrees and air temperature in degrees F or C. Speed can be
displayed in Knots, MPH, Km/H or M/S with selectable display
damping. Temperature can be displayed in degrees Fahrenheit
or Celsius. Speed, direction and temperature may all be
calibrated using the front panel keys.
In addition to the standard 0-360 degree scale you can view
wind direction on an expanded +/- 90 degree scale.
Five levels of backlighting can be selected and remotely
switched ON/OFF. All setup and calibration constants are
saved to a non-volatile memory. The WSD110 outputs NMEA
0183 data of wind speed, direction and air temperature and
works on both 12 and 24 VDC systems.
The WSD110 with its large display draws only .025 amps and
only .045 amps with full backlighting.
