2 Installation • The installation includes 5 major steps: 1. Read the installation and operation manual. 2. Plan where to install the Compass transducer and the instrument. 3. Run the cables. 4. Install the Compass transducer and the Instrument. 5. Learn the functions and calibrate your system.

Before you begin drilling ... think about how you can make the installation as neat and simple as your boat will allow. Plan where to position the transducer and instrument. Think about leaving space for additional instruments in the future.

• A few ”do nots” you should consider: − Do not cut the cables too short. Allow extra cable length at the instrument

so it can be disconnected for inspection without having to disconnect all attached cables.

− Do not place sealant behind the display. The instrument gasket eliminates the need for sealant.

− Do not run cables in the bilge, where water can appear. − Do not run cables close to fluorescent light sources, engine or radio

transmitting equipment to avoid electrical disturbances. − Do not rush, take your time. A neat installation is easy to accomplish.

• The following material is needed: Wire cutters and strippers. Small and large Philips and a small flat head screw driver. Hole saw to cut a hole for the instrument back of 63 mm (2½"). 2.8mm drill for the Compass transducer mounting screws 5 mm (1/4") drill for the mounting holes. Plastic cable ties If you are doubtful about the installation, obtain the services of an experienced technician.


7

2.1 Installing the instrument • Place the adhesive drill template on the desired location for the instrument. Drill the

2 holes using a 5 mm (1/4") drill for the two pin bolts. Use a 63 mm (2½") hole saw to machine the clearance hole for the instrument connection socket. Remove the template.

• Screw the two pin bolts to the instrument • Put the instrument in place • Screw the two nuts from the back

Note! The two nuts must just be tightened by hand only

• Run the Nexus Network cable from the Compass transducer to the instrument. • If you want to cut the Nexus Network cable to length, cut it in the instrument end.

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). Attach the 4 cable protectors to the wires using a pair of flat pliers.

• Connect the 4 cable protectors to the 4-pole jack plug as shown. Apply silicon paste on all locations as shown. Note: Must be done to avoid corrosion.

3 Installation 3.1 Location of the NX Compass

The transducer should be mounted horizontal or vertical (see pictures below). The surface may be leaning ± 10 degrees from the horizontal or vertical plane. It should be mounted perpendicular to the fore aft line (see picture on next page). Try to mount the transducer reasonably well away from magnetic disturbances such as objects containing iron, loudspeakers, window wipers etc. For safe distances, see page 11. The transducer does not have to be mounted in the centre of the boat. The optimum position for the transducer is at the centre of gravity of the boat. At that position there may be magnetic disturbances, therefore the transducer normally is installed more forward. The transducer is normally mounted below deck but its water resistant enclosure allows for outside mount, which is preferable for some steel boats.

3.2 Check the location: If you have large disturbance sources or a steel boat we recommend to connect the transducer, mount it temporary and check the readouts before mounting it permanently.

4 Electrical installation The transducer is connected to the Nexus Network. After the electric installation you should check the readings on the instrument before you proceed with the automatic compensation. If the readings are inaccurate with more than 20º at any course, the transducer should be relocated.

5 First start

5.1 Initialising the instrument You will be asked to press SET (PrESkey) on the instruments the very first time after installation. This will give the instrument a logical ID number that belongs to your specific Nexus Network. Press SET, on each installed instrument, one at the time.

Always wait for the text ‘Init OK’ to be displayed, before you press SET on the next instrument!

The first unit ID number is 16, then 17 and so on in the order which you press SET. The example shows that the NX Compass instrument has version no. 1.00 and ID number 17

5.3 Main function This function will always display Heading.

5.4 Analogue function The analog scale is showing heading (5 degree / segment) or Steer function (2 degree/Segment). To toggle between these two, press PAGE.

5.5 Sub-functions Select sub-function with PLUS or MINUS.

5.5.1 Steer function[STR] The text [STR] (STeaR Function) and its value is displayed below. To change the steer reference, press SET and select the new value with PLUS or MINUS. A short press on C will set the current heading as steer reference.

5.5.2 Boat Speed [BSP] The text [BSP] (Boat SPeed) and its value is displayed below. The unit for [BSP] (Boat SPeed) may be selected between [KTS] (KnoTS), [M/S] (Metres/s), [MPH] (Miles/h) or [KMH] (Km/h).

5.5.3 Velocity Made Good (VMG) The text [VMG] (Velocity Made Good) is displayed with the actual boat speed towards or against the Wind. The water and wind speed information are taken from the respective transducers which are required to provide VMG. 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.
