Introduction
Thankyou for purchasing a Raymarine product. We are sure your ST60
instrumentwill give you many years of trouble-free operation.
Thishandbook describes how to install and use the Raymarine ST60
Tridatainstrument. This instrument provides accurate depth, speed, trip
andtimer information, on a h ighq uality Liquid Crystal Display (LCD).
Theinstrument is constructed in a rugged weather-proofed case to pro-
videreliable performance, even under the most demanding conditions.

Data inputs

TheST60 Tridata instrument can fulfil master and/or repeater roles by
receivingdata either from the appropriate transducers and/or from a
SeaTalkinstrumentation system.

SeaTalk

SeaTalkenables a number of compatible instruments to operate as a
single,integrated navigational system. Instruments in a SeaTalksystem
arelinked by means of a single cable, which feeds both power and data.
Instrumentscan therefore be added to the system by plugging them into
thenetwork. SeaTalk is flexible enough to adapt to any number of
compatibleinstruments without requiring a central processor. SeaTalk
canalso communicate via an interface, with non-SeaTalk equipment
usingthe internationally-accepted National Marine Electronics
Association(NMEA) protocol.
