Introduction
Thank you for purchasing a Raymarine product. We are sure your ST60 instrument
will give you many years of trouble-free operation.
This handbook describes how to install and use the Raymarine ST60 Depth
instrument. This instrument provides accurate depth information, in either feet,
meters or fathoms, on a high quality Liquid Crystal Display (LCD). The instrument
is constructed in a rugged weather-proofed case to provide reliable performance,
even under the most demanding conditions.
Data inputs
The ST60 Depth instrument receives data either from an appropriate depth
transducer and/or from a SeaTalk instrumentation system.
SeaTalk
SeaTalk enables a number of compatible instruments to operate as a single,
integrated navigational system. Instruments in a SeaTalk system are linked by
means of a single cable, which feeds both power and data. Instruments can
therefore be added to the system by plugging them into the network. SeaTalk is
flexible enough to adapt to any number of compatible instruments without
requiring a central processor. SeaTalk can also communicate via an interface, with
non-SeaTalk equipment using the internationally-accepted National Marine
Electronics Association (NMEA) protocol.
In a SeaTalk system, each instrument can be either a master or dedicated repeater
unit. A master instrument is directly connected to a transducer (the device that
provides the raw data), and provides data and control for the service it is
providing, to all other equipment on the SeaTalk network. A slave instrument is
