  • Page 8: Installation

    WIND DATA Installation You can install the NX2 Wind Data in three different ways: • The wind transducer connected directly to the NX2 Wind Data instrument • By using the connection kit when both log and wind transducers are installed with a single Wind Data.

  • Page 9: Installing The Instrument

    Run the Nexus Network cable from the Server to the instrument. • If you want to cut the Nexus Network cable to length, disconnect 4-pole jack plug and cut the cable. Peel off about 35 mm (1,4") of the cable insulation. Remove about 6 mm (1/4") from the 3 isolated wires (the 4th wire is an earth / screen).
  • Page 10 WIND DATA • Apply silicon paste to the instrument connection pins at the back of the instrument. Press the jack plug onto the instrument pins. Press the cable in to the cable leads. • Mount the connection back cover with the screw. Your instrument installation is done!

  • Page 11: Installing Cable

    3A Fuse Connections in Nexus Network If you already have a Nexus Network i.e. a Server, it is more practical to connect the transducer to the Server due to the single instrument cable installation. Note, set C71 OFF (see 6.5.1)

    220 log, you may connect the single log pulse wire from that instrument to the Wind Data instrument terminal 4. From log transducer, NEXUS, Star, D-20, 2200 or 220 3A Fuse If you don’t have a log instrument, but want to install a log transducer, use the connection box (Art.

  • Page 13: First Start (Only In A Nexus Network)

    The Server automatically gives the first unit ID number 16, then 17 and so on. The order in which you press SET is the same order as the instruments will be given a logical ID number on the Nexus Network.

  • Page 17: Main Function

    WIND DATA Main function Top data is relative Wind angle, [AWA] (Apparent Wind Angle). As an alternative to [AWA] the following can be displayed: [AWS] (Apparent Wind Speed). [TWA] (True Wind Angle) if the log transducer is connected. [TWS] (True Wind Speed) if the log transducer is connected. To change between these functions, see C12, 6.1.2.

  • Page 18: Sub-Functions

    Wind. The water speed information from the log transducer is needed. The speed information can be taken from the log transducer or from Nexus Network. VMG = 0.0 knots when the true Wind angle is perpendicular to the boat. 4-17...

  • Page 19: Battery Voltage [Bat], Option

    Water temperature [TMP], option The text [TMP] is displayed with water temperature in Celsius or Fahrenheit. This function require a NX2/Nexus or Star log transducer. 5.5.9 Trim function for optimum Wind angle or speed, option The text [TRM] and [OFF] is displayed when this function is off. The trim function can be used as an aid to keep the correct tacking angle or to discover speed changes caused by sail or rig trimming.
  • Page 20 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.

    WIND DATA 5.6.5 BTW / NXT, Bearing and angle deviation relative next course To get this function, set NAV = On C14 (See 6.1.4). This function is using both the Compass and the navigator information to calculate the angle deviation between the bearing and the course after tack.
  • Page 25 WIND DATA Down Wind: When sailing down Wind, the boat can always be sailing at the highest WCV (speed towards the mark). When [NXT] is [00°] you should jibe because your drift is not important. The functions [BTW] and [NXT] is toggling, but can be locked or unlocked by use of the SET.

  • Page 26: Calibration

    WIND DATA Calibration To get the most out of your NX2 instrument, it is important to carefully calibrate the instrument. The calibration values are stored in a non volatile memory. To access calibration PAGE, press and hold SET more than 2 seconds. To select a calibration code, press MINUS, PLUS and PAGE as required.
