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,
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.
