2.8 mm (0.11") drill for the mounting holes Plastic cable ties If the cable is not long enough, you can buy the optional Nexus 8 m (26 ft) extension cable ( Art. No.21266-8 ), or use left over Nexus cable from other installations. The same 4-pole Nexus cable is used for all connections.
Drill the 4 screw holes using a 2.8 mm (0.11") drill. Mount the Server using the 4 mounting screws. Apply silicon paste on the screw terminal. Connect the 8 m Nexus Network cable labelled number 5 and supplied with cable protectors to the Server on pins 5, 6, 7, and 8.
Run the Nexus Network cable from the Server to the instrument. Cut the Nexus Network cable to length. Peel off about 35 mm (1,4") of the cable insulation. Remove about 6 mm (1/4") from the 3 isolated wires (the 4:th wire is a earth / screen). Attach the 4 cable protectors to the wires using a pair of flat pliers.
INSTALLATION Silicon paste Silicon paste Apply silicon paste to the instrument connection pins at the back of the instrument. Press the jack plug onto the instrument pins. Press down the cable in the cable leads. Mount the connection back cover with the 1 screw. Mount the instrument in the pre-drilled position.
Install the transducers according to the separate instructions supplied with each transducer.

Red wire to Server pin 2 (ALARM RED). Black wire to Server pin 4 (BLACK). 2.6.4 Nexus instruments All Nexus instruments are connected directly to the Nexus Network in a daisy chain. They all use the same colour coded 4-pole jack plugs. (For instrument installation, see 2.2).
GPS, Decca, Loran, NMEA compass and wind transducer etc. If a NMEA instrument is connected, most information will be available and can be displayed on the Nexus Network. You must know which 2 cables from your other NMEA instrument carry the NMEA out signal. If you have trouble call the dealer you bought your NMEA instrument from.
Note b: We do not recommend the use of NMEA transducers like wind and compass, because the update rate of data is slow compared to the very fast Nexus data bus. Note c: If the NMEA instrument has only one output cable, put a ”bridge”...
INSTALLATION Note a: Try to keep the power cables as short as possible. Note b: Up to 32 Nexus instrument units (Server, digital and analogue instruments, Autopilot servo-unit or a Nexus GPS) can be connected to the single Nexus data bus cable.

FUNCTION OVERVIEW Function overview The functions in the Multi Control instrument are divided into 4 pages: SPEED, DEPTH, NAVIGATE and WIND. The selected page is indicated by the LCD arrow at top of the display. Each page has 2 types of functions that can be displyed together: 1.
SPEED FUNCTIONS SPEED functions SPEED main-function Boat speed through the water. Unit available in knots (KT), km/h (Kh) or miles/h (Mh) (See 12.1.2,C11). If a navigator is connected, speed over ground (SOG) can be displayed. (See 12.1,C11 and C13). SPEED sub-functions 6.2.1 TRIP LOG (TRP) 0-199,99 NM, only displayed in NM.
Page 30
SPEED FUNCTIONS Default value is (LOW), for use in calm sea. But if the sea is rough, you may want to ”stabilise” the readout on the display, then select (MID) or (MAX). Damping is set separately for each instrument. 6.2.8 DEPTH (unit/DPT) Depth from the water surface or the keel depending on calibration setting (See 12.2.3, C22).
DEPTH FUNCTIONS Depth functions General information Alarm on = minute sign ( ´ ) displayed above the last depth digit in the sub-function. Alarm off = no minute sign ( ´ ) displayed. The alarms will be triggered, if the actual depth becomes less (shallow alarm), or more (depth alarm), than the set depth value.
DEPTH FUNCTIONS You can either store the suggested values or set your own values. The logic is that when you are at anchor, the alarm will warn you if the boat is drifting towards deeper or shallower water. (See 7.4). 7.2.4 TEMPERATURE (TMP) Water temperature.
DEPTH FUNCTIONS Set and turn on shallow (SHA) and depth alarm (DEA) Select shallow (SHA) or depth (DEA) alarm, press KEY. The first digit in the previous value flashes. If you want to reset the previous value to zero (0), Press DOWN and UP together.
NAVIGATION FUNCTIONS NAVIGATION functions NAVIGATION main-function Heading 000° to 359°. Heading true (HT) or heading magnetic (HM) can be displayed if the compass transducer is connected. (See 12.3, C32, C47). If a navigator is connected, course over ground (CG) can be selected instead of compass heading.
Figure of merit (F) is a factor for the GPS reception quality on a scale from 1 to 9 where F1 = best reception and F9 = no reception. This function is only valid if a Nexus GPS receiver is connected to the Nexus Network. Steer reference (Pilot) The sub-function (Pilot) is intended to be used together with the optional analogue instrument steer pilot (Art.
Automatic waypoint, corrected for drift and current (AWA)=Apparent wind angle Manual (OFF)=Steer pilot off When any steer reference function is activated, the text on the display will be copied and shown on all Multi Control instruments in your Nexus Network.
(Pilot OFF) function. (Available from Server software version 1.9.) 8.3.3 Steer reference (BTW) This function requires the Nexus or NMEA compass transducer and a Nexus GPS or NMEA navigator. When selected, the function displays (BTW) and the analogue steer pilot instrument displays the difference between the compass heading and the bearing to waypoint (BTW).
NAVIGATION FUNCTIONS 8.3.4 Steer reference (CTS) This function requires log transducer, Nexus or NMEA compass transducer , Nexus GPS or NMEA navigator. When selected the function displays (CTS) and the analogue steer pilot instrument displays the difference between the compass heading and the bearing to waypoint (CTS) including set and drift.
When a Nexus Autopilot is activated in wind mode, the (AWA) function on the Multi Control instrument can be used to perform an automatic tack. The minus sign ( - ) in front of the wind angle value = port side.
Nexus Network which is keeping the waypoints in memory, but the waypoints can be reached from all instruments. If a portable Nexus GPS is connected, the Server takes over the navigation. If a Nexus GPS Navigator instrument (art no 21032) and...
NAVIGATION FUNCTIONS If the longitude is more than 99° East or West the cursor for the 100:th digit flashes. If the 100:th digit is not displayed, press UP to activate it. To enter the new longitude co-ordinates, and to select hemisphere East (E) or West (W), press MODE, DOWN and UP as required.
The (Go FROM) position is mainly used to define your track line, to calculate XTE etc. When the Nexus Network is set to be a repeater for an external NMEA navigator which is performing the navigation, you can display the waypoint in the (Goto WP) function, but you can not edit a waypoint other than in the NMEA navigator.
NAVIGATION FUNCTIONS To add waypoints/legs to the sailplan, press UP to display (Goto NXT). To unlock and add waypoints/legs, press KEY and repeat the above described process. To exit the (Goto WP) function, press MODE. When you arrive at a waypoint in the sailplan, a series of automatic actions take place: The audible and visual arrival alarm is triggered.
NAVIGATION FUNCTIONS To start navigation to waypoint number (06), continue from above example and press UP until (Goto NXT) is displayed. To unlock the value, press KEY. To change from waypoint number (05) to (06), press UP. To store the new value, press KEY. From waypoint (05) to (06) the bearing is 345°...
Factory setting radius value is 0.10 nautical mile. (See 12.3.12, C41). When the audible alarm is triggered (beeps 3 times), the text (ArriVAL) flashes 3 times on all connected Multi Control instruments. After the arrival alarm the instrument will revert to the previous displayed function.
WIND FUNCTIONS Wind functions WIND Main-function Apparent wind angle (AWA), true wind angle (TWA) 000° - 359°, apparent wind speed (AWS) or true wind speed (TWS): The main-function WIND, allows you to display wind angle or wind speed, true or apparent. The wind angle is indicated by a symbol to the right of the wind angle value: = Wind from port side.
WIND FUNCTIONS 9.2.2 DAMPING (SEA) Damping of wind information. Controls the response time of wind changes. To change damping, press KEY. To select damping level, press UP and select from: LOW) 1 sec, (MID) 5 sec and (MAX) 22 sec. To store the selected value, press KEY. Factory value is (LOW), for use in calm sea.
= heeling to port side. The Server will compensate the wind angle and the wind speed errors due to heeling. The compensation is already implemented in the Nexus Network, but a transducer to indicate roll is not yet available. Tactical function This function requires a compass transducer and displays course memory.
Page 52
WIND FUNCTIONS changed compared to the wind, that is you will be changing your heading due to the wind shifts. The tactical function will give you a fast and exact information about any wind shift compared to the magnetic heading. Select sub-function (TAC).
(MOB) button. (See 2.4.1). If only a compass and a speed transducer is connected, dead reckoning (MOB) will be displayed on both the Multi Control and the SPEED Log instruments. Dead reckoning (MOB) is also a very useful information, since a person in the water will drift almost as fast as the boat.
CUSTOMISE YOUR DISPLAY Customise your display All sub-functions are organised in a list under the main-function. The first location in the sub-function list is an empty display. You can have your favourite sub-function moved in the same sub- function list, or copied and locked to any other page. 11.1 Move and lock a sub-function Example: In SPEED page, move and lock the sub-function depth...
CUSTOMISE YOUR DISPLAY 11.4 Cancel a moved or locked sub-function Example: To cancel the previous moved sub-function true wind speed (TWS) from SPEED page. Select the new combination, SPEED page and sub-function (TWS). Press MODE and KEY together. All digits flash. To cancel the moved sub-function, press DOWN and UP together.
CALIBRATION Calibration To get the most out of your Nexus Network, it is important to carefully calibrate the Network. The calibration values are stored in a non volatile memory. To access calibration mode, press and hold KEY more than 2 seconds.
CALIBRATION 12.1.4 C13 (OFF SOG) Select speed transducer to be displayed as main-function under SPEED. (OFF) = Boat speed through the water from log transducer. (ON) = Speed Over Ground (SOG) from navigator. 12.2 C20, calibration of depth 12.2.1 C20 (RET) To return to normal mode, press KEY.
CALIBRATION 12.3.3 C32 (00.0 VAR) Magnetic variation. Maximum +/- 99.9°. Easterly variation = underlining ( _ ) sign. Westerly variation = minus ( - ) sign. The local magnetic variation is usually printed in the sea chart. 12.3.4 C33 (Auto DEV) Automatic compass deviation, (see 12.4.1).
(OFF) = All headings and bearings will be true. Note a: In the (Goto WP) function, the bearing for every leg will always be displayed as true bearing. Note b: The setting is only affects the independent Multi Control instrument in which is set. 12.4 12.4 Compass calibration...
CALIBRATION If the deviation is not corrected, an error message will be displayed. To verify the automatic compass deviation, perform an automatic compass check (Auto CHK), (see 12.4.2). Note: You will get the best result in calm water with a smooth turn on the steering wheel independently of how the circle is performed.
Select type of heading transducer, compass or navigator (COG), to be displayd as main-function under NAVIGATE. When COG is available (Nexus or NMEA), and no compass transducer is connected, you can set C75 to (ON), COG will also be used to compute TWD (true wind direction) 12.5.3...
By the term ”navigating”, we mean the active instrument in which the waypoint memory is used to calculate the navigation data, i.e. BTW, DTW etc. There can only be one instrument on the Nexus Network which is navigating. (OFF) = The Server is navigating.
The Server supports 29 different NMEA sentences. This means you can select up to 16 of the 29 available NMEA sentences. The Nexus Network uses the NMEA 0183 sentences, version 1.5 and 2.0. The number in brackets, example (C79), is the calibration code for the factory slot number given to the NMEA sentence.
Page 67
CALIBRATION (VLW) Distance travelled through the water (C87) (VPW) Speed relative to the wind (C88) (VTG) Distance made good and distance over ground. (C89) (VWR) Apparent wind speed and wind direction (C90) (VWT) True wind speed and direction (C92) (WCV) Waypoint closure velocity (C93) (WPL)
To select the sentence, press DOWN or UP until found. To lock the selected sentence, press KEY. One of the advantages with the Nexus Network is the very fast transmission speed of data compared to the relatively slow NMEA standard (about 10 times faster). Therefore we recommend that you use Nexus instruments and transducers for better accuracy.
1) Position related data: Position, SOG/COG, time, and a limited amount of satellite status if a GPS is connected. The information is read if no other Nexus GPS is connected. If a Nexus GPS is connected, it will take over the navigation.
PC. One contains TBS (target boat speed), the other CAD (customised angle data ) and CFD (customised fixpoint data ). These 3 data are retransmitted on the Nexus Network and can be displayed as a sub-function on the Multi Control instrument.
