If the instrument are to be used in a Nexus Network, there are some systems settings that are dependent on where the transducers are installed, i.e. at the instrument or at the Server.

By using the connection kit when both log and compass transducers are installed with a single cable to the NX2 Compass instrument. • The installation may also include a NX2 Server where all transducers may be connected. All data including power will pass along one cable. •...
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).

COMPASS • 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!
3A Fuse 2.1.2 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 5.4.1).

COMPASS If you have another log instrument i.e. a NX2 Log, Nexus log, a Star log, a D-20 log, a 2200 log or a 220 log, you may connect the single log pulse wire from that instrument to the Compass Data instrument terminal 4.
ID when the Compass transducer is connected direct at the instrument and the setting in C71 is on (default setting). Initialising the instrument in a Nexus Network At the first power on after installation, you will be asked to press SET [PrSKEY].
COMPASS Operation About this manual • Each time a push-button is referred to in this manual, the push- button name will appear in bold and CAPITAL letters, e.g. PAGE. • Unless otherwise stated, the push-button presses are momentary. • Each time a function is mentioned in the text, it will be in brackets and in the same format, where possible, as displayed, e.g.
COMPASS How to use the 4 push-buttons COMPASS HEADING COURSE or STEER information INFOTEXT SUB- FUNCTION CLEAR PLUS PAGE DOWN 4.2.1 PAGE A press on PAGE, changes the mode page of the graphical display. It scrolls in a circular pattern, one step for every press. The PAGE button is also used to move the cursor when in edit mode.
To select between the 4 light levels, press UP: [LOW], [MED], [MAX] and [OFF]. To lock the selected level, press SET. The selected light level will be copied to all NX2 instruments connected to the system. When the lighting is on, it is not possible...
COMPASS Main function Top data is COMPASS HEADING. Top data is either magnetic or true HEADING and your choice is set in the set-up. When magnetic Compass course is selected, the small MAG sign is lit on the LCD. Analogue function Press the PAGE button to change from Compass heading to steer reference.
COMPASS Sub-functions Select sub-function with PLUS or DOWN. Information text for the sub-function is displayed. You may also ”park” your favourite function so it will automatically be displayed after power on. Press PAGE and SET together to ”park” the displayed function. The display will flash once to confirm that you have ”parked”...
You may also use one or more external TRIM buttons to set new references. To be able to utilise the wind steer function AWA, you will need either a Wind Data instrument, or a NX2 Server with a wind transducer. For the [BTW] and [CTS] functions you will need a NX2 GPS or any NMEA GPS ,Decca or Loran C navigator to be connected.
NX2 Autopilot is installed (and activated for wind steering). Use the PLUS and MINUS to change the direction of the WA pointer, then press SET. Your NX2 Autopilot, if activated in wind mode, will now perform an automatic tack. 4.5.5 Steer referens [BTW], option The text [OFF] or [MEM] is displayed.
COMPASS 4.5.7 Tactical use of [MEM] Function [MEM] is used to discover the smallest of wind shifts during upwind or downwind sailing, but it is your tactical decision wheter to tac or to stay on course. The Compass Data instrument will automatically keep track on wheter you are using the starboard or port MEM if the course difference between each trim is more then 45º.
4.5.11 Water temperature [TMP], option The text [TMP] is displayed with water temperature in Celsius or Fahrenheit. This function requires a NX2, Nexus or Star log transducer. 4.5.12 Dead reckoning [CMG / DMG] This function requires both Compass and Log transducers.

COMPASS When using the Compass Data in a Network with more then 3 transducers, we recommend you to use the NX2 Server. One Nexus Network power/data cable is used to connect all instruments. You will have NMEA 0183 in/out. Depth information will (if used) be repeated at more than one NX2 instrument.
C20 - C24 = BSP, Log transducer and temp calibrations. C30 - C37 = HDC, Compass settings. C70 - C74 = CON, Configuration of the NX2 system. To change a calibration value, press SET. To select calibration value, press DOWN, PLUS and PAGE as required.
If you suspect a current in the water, drive the boat in both directions and divide trip counter distance by two. If the Compass Data is installed with NX2 Server where the log is already calibrated, no further calibration is needed.
COMPASS 5.2.3 C23 Unit for temperature Select degree Celsius [C] or degree Fahrenheit [F]. 5.2.4 C24 Temperature offset By adding a positive or [-] negative value here, it will be added as an offset before displayed as the temperature. C30 Compass Settings To return to normal mode, press SET when the text [rET] is displayed.
COMPASS The text [CHK] starts flashing and a pointer will show you the course where to end. When you have taken the boat through the minimum 360° turn, press SET again, and if successful, the text [CHK Atd] will appear again, otherwise, ERR 17 or ERR 19 will appear, i.e. the difference between the last Autodeviation and this Autocheck is to big to be accepted.
COMPASS the boat is horizontal. By entering a minus sign [-] in front of the value the roll will be decreased by the value. When the offset is without a minus sign, it will be added. When a roll transducer is connected, both wind speed and wind angle will be compensated for the roll and thus increasing the accuracy.
To return to normal mode, press SET when the text [rET] is displayed. In the configuration you will be able to tell the Nexus Network where have installed the log and wind transducer. This is important because you may optionally install those transducers at the Server instead of the instrument.
COMPASS 5.4.4 Connection of trim button Connect the trim button as per the drawing. The button should make a short connection when pressed. It is also possible to connect more than one button in parallel, for example one on starboard and one on port side. Article number for the push button:19763.
