The Compass transducer is either connected directly to the Nexus
Compass Data instrument or by use of the connection kit art.no. 21453.
The kit is used when the NEXUS log transducer are installed to form a
sole Compass Data system without the NEXUS Server. In a larger
NEXUS system, the installation may preferably include the Nexus Server
adding NMEA in/out, and where all transducers may be connected. All
data including power will then pass along in one single NEXUS network
cable, making installation, maintenance and service very easy.
The installation includes 6 major steps:
1. Read the installation and operation manual.
2. Plan where to install the transducers and instruments.
3. Run the cables.
4. Install the transducers and instruments.
5. Take a break and admire your installation.
6. 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 transducers, the Server and the instruments. 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 or at the Server 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 may accumulate.
−
Do not run cables close to fluorescent light sources, engine or radio
transmitting equipment, in order to avoid possible electrical
disturbances.
−
Do not rush, take your time. A neat installation is easy to do.
The following material is needed:
Wire cutters and strippers.
Small and large Philips and small flat head screw driver.
Hole saw for the instrument clearance hole 63 mm (2½").
2.8 mm (
7
/
64
") drill for the mounting holes in wood.
3.2 mm (
1
/
8
") drill for the mounting holes in fibre glass.
Plastic cable ties.
If you are doubtful about the installation, obtain the services of an
experienced technician.
