1. Put the mounting bracket (3) on the vessel where you are to at-
tach it. Make sure that you will not cause damage to other equipment,
ropes or electrical cables when you attach the bracket.
2. Use the mounting template to mark the position of the four attach-
ment holes. Examine the location again to make sure that it is a good
location, then drill 4 x 3.5 mm holes.
Note: If screws are to attach the bracket to wood, drill 1.5 mm pilot holes and
not 3.5 mm clearance holes.
3. Use two screws to temporarily attach the bracket to the vessel.
4. Put a 15 mm dia. drill bit into the centre of the mounting bracket
and drill a cable access hole into the vessel. Remove the two attach-
ment screws and bracket. Deburr all holes and clean them fully.
5. Put a 15 x 6 mm grommet on to a NMEA 2000 micro cable (Not
supplied). Carefully push the cable through the hole and set the grom-
met in this hole.
6. Push the NMEA 2000 micro cable through a bracket gasket (if
used) and then the bracket. Align the bracket to its attachment holes
in the vessel.
7. Use the not magnetic stainless steel screws to attach the bracket
to the vessel.
Do not cause damage to the cable or surface of the vessel.
8. Align the keyway in the cable connectors and then push the NMEA
cable into the socket in the bottom of the Navsensor
(1) .
Turn the collar to lock the cable
9. Make sure that the arrow on the bottom of the sensor is aligned
with the vessel’s keel
10. Put the Nav sensor on to the bracket. Carefully push the cable
through the grommet in the access hole while you do this.
11. Tighten the set screw
(2) (3 mm hex key).
12. Get the free end of the NMEA 2000 micro cable and connect it to
a T-junction of a existing NMEA 2000 backbone.
Note: Make sure that you set the cable away from sources of Electrical
Magnetic interference. Also make sure that the foot of a person cannot touch
the cable and cause injury to the person or cause damage to the cable.
