1 Introduction
General information
The IS20 Graphic is a multifunction instrument that
displays speed, depth, heading, position, wind and
environmental data measured by sensors and other
equipment connected to the system.
Navigational data, engine/battery status and vessel
parameters as e.g. accumulated log and rudder angle
may also be displayed.
The instrument calculates speed trim, wind head/lift,
trip distance and time, average speed, set and drift
parameters. A race timer is also included in the IS20.
Instrument layout
The IS20 has a 130 * 104 pixels LCD. The display may
be set to red or white illumination color, and the contrast
and light level are adjustable.
The instrument is equipped with 2 SimNet connectors,
an
d with one NMEA0183 input connector.
Keys
The instrument is operated by 6 keys. These are used to
adjust the light, scroll between data pages, to operate
the menu and to set parameter values.
Softkeys
When the basic operation of the
keys is changed, softkey symbols
will be displayed right above the
keys to indicate the alternate
function.
The softkey symbols are illustrative, and they are
described under the functions as these appear in this
manual. The following general softkey symbols are used:

IS20 system examples
The IS20 may be installed as a stand-alone instrument
system, or as part of an advanced instrument or steering
system on the boat.
The figures on the next two pages show simplified
illustrations for basic and an expanded IS20 system.

SimNet group function
The SimNet group function provides global control of
groups of units. This option is used on larger vessels
where many units are connected via the SimNet network.
By assigning several units to the same group, a function
change or update on one unit will have the same effect
on the rest of the group members.
The table below shows available SimNet groups.

Units Simrad, None, 1-6 Simrad
Language Simrad, None, 1-6 Simrad
Damping Simrad, None, 1-6 Simrad

The figures on next page illustrates how the instruments
on a flybridge and in a cockpit are assigned to separate
language, damping and display groups, and how this
affects the setup for the different instruments.
The SimNet groups are congured during system
configuration. Further information about how to set up
the groups are found in SimNet groups.
