Welcome aboard the Nexus Network!
Thank you for choosing FI-30 and welcome to the world of the Nexus Network.
Through this manual we would like to help you install, operate and understand your
new Nexus Network.
The FI-30 speed log may be used stand alone where the log transducer is
connected direct to the Speed Instrument or in a Nexus Network where the log
transducer is connected to the Server and the Speed instrument work as a
repeater.
The Speed instrument will automatically sense if it is stand alone or in a
Nexus Network.
The Server is the ”heart” of your Nexus Network, to which transducers for speed,
depth, heading, wind and navigation (GPS, Loran or Decca) are connected.
From the Server the single Nexus Network cable transmits power and data to the
instruments, which repeat the information sent from the Server, or other FI-30
transducers.
The Nexus Network is designed with the industry standard RS 485 databus, which
allows you to connect up to 32 FI-30 instrument units on the single Nexus Network
cable, thereby allowing you the flexibility to easily develop your system. The Nexus
Network is capable of carrying data 10 times faster than NMEA 0183.
The connection system, with a single 5 mm (1/5") cable and 4-pole jack plugs with
cable protectors, makes the installation easy. No need to drill big holes and the
cable can be cut to exact lengths. The connections at the Server are colour coded
and marked with a number for easy reference.
The instruments large display gives you very good viewing possibilities from any
angle, even in bright sunlight. The display and the five push-buttons have red back
lighting which you can set to three different lighting levels.
To get the most out of your new FI-30 product, please read through this manual
carefully before you start your installation.
Again, thank you for choosing FI-30. If you see us at a show, stop by and say
hello.
Good luck and happy boating!

2 Installation
• The installation includes 6 major steps:
1. Read the 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, Server
and 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 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 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 do.
• The following material is needed:
Wire cutters and strippers.
Hole saw for the instrument clearance hole 63 mm (2½").
Hole saw for the Through hull fitting hole 43 mm (1 11/16").
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.
