Nexus Wind Data Installation And Operation Manual page 18

Select the level of dampening [d0-d9] and confirm with the KEY.
The default (or latest used) Wind angle is displayed. You may accept the
proposed angle by pressing the KEY or enter a new Wind angle with UP,
DOWN and MODE before confirming with KEY.
The entered Wind angle will be lost when power off. You may however
select a default Wind angle in set-up. See C64 5.4.7.
Every time you select this function, or after power up, the pre-set value is
proposed.
On the display you will see the text TRM and AWA toggling together with
your Wind angle. On the graphic part you will see your reference angle as
one straight horizontal segment when actual angle is equal to the pre-set
angle. At the same time you will see apparent and true Wind angle.
The deviation is displayed visible upwards or downwards from the
horizontal line to +/-15°. The maximum visible deviation is 15°. When the
deviation is between 15° and 30° the 15° sector is lit. When larger then
30° the segment sector is blanked out.
Trim on speed:
Select the trim function.
Press UP and DOWN together. Select text (BSP) by pressing UP and
confirm with KEY.
There is a number of different "speeds" to be used for trimming. The
most common is [BSP] (Boat SpeeD) and [VMG] (Velocity Made Good).
The Wind Data instrument can also display deviation from optimum
calculated boat speed [TBS] or (Target Boat Speed).
The TBS is normally calculated by use of polar diagram on PC with
racing software. The value "Target Boat Speed" is transmitted through
the Nexus Server on the NMEA 0183 input. The Server will then transmit
TBS on the Nexus Network.
On the Wind Data display you will see both the digital value in % and the
graphical value as a 2% variation for each segment.
You may select "speeds" to TRIM, from this list:
BSP Boat speed
AWS Apparent Wind Speed
TWS True Wind Speed
SOG Speed Over Ground
