however select a default Wind angle in set-up. See C64 6.4.7.
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 CLEAR. Select text (BSP) by pressing PLUS and confirm
with SET.
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 NX2 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
DRF Drift
WCV Speed towards a waypoint
VMG Velocity Made Good
TBS Optimum speed based on polar diagram
OFF Function is OFF
Each sector represents 2°
