1Introduction
1.1 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.
1.2 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,
and 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

keys to indicate the alternate
function.

described under the functions as these appear in this
manual. The following general softkey symbols are used:
OK
Cancel

The IS20 may be installed as a stand-alone instrument
system, or as part of an advanced instrument or steering
