ST290 Instrument System Owner’s Handbook
The system components communicate with one another over Raymarine
SeaTalk and SeaTALK
2
buses.
Both digital and analog instrument types are available.
System buses
The ST290 products are connected via Raymarine SeaTalk and
SeaTALK
2
buses to form a single, integrated system. On each bus, the
ST290 products are linked by means of a single cable, which feeds both
power and data. Details of bus/product compatibility are given in
Section 6, Installation.
SeaTalk and SeaTALK
2
communicate with one another via the Data
Processing Unit.
Digital instruments
ST290 digital instruments can display a wide range of system data, on
both Graphic and Data Displays:
•
Graphic Displays use dot-matrix screens.
•
Data Displays use preformed, segmented characters.
Information on both digital instrument types is organized in ‘chapters’
and ‘pages’ to enable you to easily find the data you want.
Graphic Displays provide the most versatile way of presenting data, as
they can show dynamic graphs and other animated information, in
addition to the alphanumeric information available on both digital
instrument types. They are also used to calibrate the system transducers.
For a description of the functions and operation of the ST290 digital
instruments, refer to Section 2, Using Digital Instruments.
Analog instruments
Analog instruments are available to show:
•
Wind
•
Close Hauled Wind
•
Compass
•
Rudder angle
For a description of the functions and operation of the ST290 analog
instruments, refer to Section 3, Using Analog Instruments.
