Location of the unit

The IS20 should be mounted with special regard to the
unit’s environmental protection, temperature range and
cable length. Refer to page 59.

Avoid mounting the control unit(s) where it is easily
exposed to sunlight, as this may shorten the lifetime of
the display.

Mechanical installation

Panel mounting

The mounting surface must be flat and even to within 0.5
mm.

Drill the 4 mounting holes and make a panel cut-1
out according to the drilling template included in
the package

Use the supplied 19 mm selftapping screws to 2
secure the control unit to the panel

Apply the front panel corners3

Do not over-tighten the screws!

38 | Installation

Bracket mounting

An optional bracket is available for the IS20.

The illustration below shows the mounting details for the
bracket.

Installation | 39

Cable connection

The IS20 Combi may be connected to SimNet network
using SimNet cables.

SimNet

The SimNet cable system with very small plugs in both
ends makes it easy to run the cables. Only 10 mm (3/8”)
holes are required through panels and bulkheads.

The SimNet accessory program contains the necessary
items to make a successful installation. Refer to SimNet

cables and accessories, page 58.

SimNet cables

A SimNet unit has one or two yellow SimNet connectors.
There are no dedicated “in” or “out” connectors.

Route the SimNet cables with the figures on page 41, 42
and 43 as a guideline. Select cables and accessories from
the SimNet accessory program.

Connect products with two SimNet connectors in a daisy
chain and use drop cables and T-joiners when required.
For cable extension in-line cable joiners are available.

Total length of SimNet cable installed in a system should
not exceed 150 meter (500’)!

If you plan to extend your SimNet system in the future it
may be advantageous to prepare for it by adding a few
T-joiners in central locations. The T-joiners provide easy
access to the network and can be replaced with a new
product, or the new product can be connected via a drop
cable.



40 | Installation

The connectors are weather proof according to IP66,
when properly installed. All unused SimNet connectors

must be tted with the plastic cap to protect them

against dirt and moisture.

SimNet power and termination

The following rules should be observed when installing
SimNet:

It must have a separate 12VDC power from the 1
battery bus or the circuit breaker board to reduce
interference

It must not be connected to the supply voltage 2
terminals of the Autopilot Computer

It will power a SimNet compatible instrument 3
system. Hence SimNet to other equipment can be

supplied via the autopilot, see the gures on page

41, 42 and 43

SimNet must be properly terminated, i.e. unless it 4

is a small system (see the gure on page 41) there

must be terminations at each end of the Simrad
backbone

The SimNet network has to be terminated according to
the number and type of products connected.

In a small system consisting of maximum 5 SimNet
products and a total length of 5 m SimNet backbone
cable, you only need the SimNet power cable with built-in
termination (red disc on cable plug).

For additional information about SimNet, ask for the
separate SimNet Manual.

48 | Configuration

Calibration

After installation, certain functions in the system must be
calibrated to adapt to the physical position and type of
sensors installed.

All calibration is initiated from the CALIBRATION sub
menu.

Boat speed

The hull shape or the location of the speed sensor
may cause incorrect speed readings, and calibration is
required to ensure that correct speed and log readings
are displayed.

Configuration | 49

Calibrate by speed over ground

With a GPS connected to the system, the speed may
be automatically set identical to the speed over ground
value.

This adjustment should be made in calm sea with no
effect from wind or tidal current.

Bring the boat up to cruising speed (above 5 knots)1

Select 2 Calibrate w/SOG and press the Menu/
Enter key to start the calibration

When the calibration is completed the 3 SPD
Correction factor is set to 1.00

Manually adjust the speed value

If you experience an incorrect speed reading this can be
manually re-adjusted as follows:

Compare the speed reading with that on another ­boat

Run the boat at constant speed over a known ­distance in both directions and average the speed
reading

Then adjust the SPD Correction factor to get the
correct speed reading.

Range Change per step Default value

50 | Configuration

Depth

The default value for the depth offset is 0.0, which
indicates the displayed depth from the transducer to the
seabed (b). Refer to the illustration on the next page.

The value should be increased or decreased, depending
on whether the depth reading should be from the water
line or from the keel, respectively:

A negative offset equal to the vertical distance ­from the transducer to the keel will display the
depth as measured from the vessel’s keel (a)

A positive offset equal to the vertical distance from ­the transducer to the water line will display the
depth as measured from the water line (c)

Configuration | 51

The symbol in front of the depth reading will change to
indicate that the depth is measured from:

the keel or the water line

Range Change per step Default value Units

-10 - +10 0.1 0.0 m, ft

52 | Configuration

SimNet groups

The SimNet group function is used to globally control
parameter settings in groups of units. The function is
used on larger vessels where several units are connected
via the SimNet network.

By assigning several units to the same group, a
parameter update on one unit will have the same effect
on the rest of the group members.

For additional information about SimNet groups, refer to
SimNet group function, page 31 and onwards.

Setting the unit’s instance number

The instance number is used to identify multiple units
of the same model when connected to a SimNet or
NMEA2000 network. The instance number is added to the
product name e.g. IS20-3 for easy identification of the
unit.

Range Change per step Default value

Maintenance | 53

8 Maintenance

General maintenance

The IS20 instruments are “repair by replacement” units,
and the operator is therefore required to perform only a
very limited amount of preventive maintenance.

If the unit requires any form of cleaning, use fresh water
and a mild soap solution (not a detergent). It is important
to avoid using chemical cleaners and hydrocarbons such
as diesel, petrol etc.

Make sure that all open SimNet connectors are fitted
with a protection cap (part no. 24006355).

Always put on the weather cover when the unit is not in
use.

Service information

The main menu includes a
Service item giving access to
several options for displaying
data used when testing or
trouble shooting the system.

SimNet status

The SimNet status screen
