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

. Select text (BSP) by pressing

 and confirm  

with

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 ”

S

peed” 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.
