2Installation
You can install the FI-30 Compass in three different ways:
•The compass transducer connected directly to the FI-30 Compass instrument
•By using the connection kit when both log and wind transducers are installed with a
single cable to the FI-30 Compass instrument.
•The installation may also include a FI-30 Server where all transducers may be
connected. All data including power will pass along one cable.
•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.
Large Philips and small flat head screw driver.
Hole saw for the instrument clearance hole 63 mm (2½").
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.

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 pinbolts to the instrument
•Put the instrument in place
•Screw the two nuts from the back
Note! The two nuts must just be tighten by hand
•Run the Nexus Network cable from the Server to
the instrument.
•If you want to cut the Nexus Network cable to
length, disconnect 4-pole jack plug and cut the
cable. 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.
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 the cable in to the cable leads.
•Mount the connection back cover with the screw.
Your instrument installation is done!

2.1.1 Installing cable
The power cable is connected via a 3A fuse from the battery or at the boats fuse panel
and direct to the instrument or Server. One red and one black power wire is included.
Note, Set C71 ON (see 5.4.1).
Always connect a 3 AMP fuse between Power supply and instrument.
2.1.2 Connections in Nexus Network
If you already have a Nexus Network i.e. a Server, it is more practical to connect the
transducer to the Server due to the single instrument cable installation. Note, Set C71
OFF (see 5.4.1).
The instrument is then connected to the Server’s Nexus Network terminal (pin 5, 6, 7
and 8) or at any FI-30 instruments terminal .

2.1.3 Connection of log transducer
If you have another log instrument i.e. a FI-30 Log, you may connect the single log
pulse wire from that instrument to the Compass Data instrument terminal 4.
If you don’t have a log instrument, but want to install a log transducer, use the
connection box (Art. no: 21453).

3First start
At each power on, the instrument will first show all segments lit
up, then the ID number and software version [VER]. Number 8
is the fixed ID when the Compass transducer is connected
direct at the instrument and the setting in C71 is on (default
setting).
3.1 Initialising the instrument in a Nexus Network
At the first power on after installation, you will be asked to press
SET [PrSKEY]. This will give the instrument a logical ID number
from 16 and upwards on the Nexus Network.
To initialise the instrument, press SET, one at a time, on all
installed digital instruments,.
Note: Always wait for the text ”Init OK”
to be displayed, before you press SET
on the next instrument!
The Server automatically gives the first unit ID number 16, then
17 and so on. The order in which you press SET, will be the
same order as the instruments will be addressed by the Remote
Control, if used.
The example shows that the instrument version number is 1.00
and the given logical ID number is 16. The ID number will
always be 8 if the Compass transducer is connected to this
instrument. If the instrument is a repeater, it may have any
number from 16 and up.
3.2 Re-initialising the instrument
If and when two instruments by mistake have the same ID number, you must re-
initialise the instruments to avoid network disturbance and blockage of data.
To re-initialise the instrument, press MINUS and PLUS together
during the power up sequence, i.e. when version and ID
numbers are displayed.
The display test is then re-started on all instruments and you will
be asked to press SET (ANY KEY) on each instrument as
explained above.
Note! If you do not succeed to re-initialise, we suggest you disconnect (just pull out the
connection plug) all, except one of the instruments that had the same ID number, then
repeat the above procedure. Reinstall the instruments and redo the ”PRESKEY”
procedure.

4.5.3 Advanced use of (STR) MEM
The text [STR OFF] or [MEM] is displayed.
Press CLEAR. The text [OFF] or [MEM] is flashing, select one of
the following four different steering modes that are available;
[MEM], [AWA], [BTW], [CTS] or [OFF] and press SET.
Each function is explained in detail. The function [STR] is a Nexus network function,
i.e. it will transmit the steer reference data to other FI-30 instruments. The steer
information used on the Compass Data instrument is functioning within the same
concept as the STEER Pilot instrument. The instrument is especially designed for
displaying steer or Compass heading information in the most efficient way. You may
also use one or more external TRIM buttons to set new references. To be able to
utilise the wind steer function AWA, you will need either a Wind Data instrument, or a
FI-30 Server with a wind transducer. For the [BTW] and [CTS] functions you will need
any NMEA GPS, Decca or Loran C navigator to be connected.
Also, if you have installed a FI-30 Autopilot, and it is activated, you may change the
course or wind angle by using the STR function.
You can not activate or turn the pilot off with STR, so use with care !
4.5.4 Steer reference [AWA], option
The text [OFF] or [MEM] is displayed.
This function may be used when sailing upwind or downwind, where Compass course
is chosen to be the secondary steer priority, after windangle.
Press CLEAR. The text [OFF], [MEM] or the previous selected function is flashing,
select [AWA] and press SET.
A copy of the present windangle is flashing, press SET to accept, or enter preferred
windangle, then confirm with SET.
You will now see the text WA flashing with a pointer at the left or right side. For now,
just press the SET again, then press PAGE to see the closed
hauled angle.
Example, you have set 40°as your tacking angle.
The boat is sailing with the pre-set wind angle when the
LCD pointer is displayed as a vertical line strait up. A
windangle deviation is displayed as a filled sector. When
sailing too high, segments are.
