1.1
Overview
This chapter assumes the ST60 Graphic Display has been fitted in
accordance with the instructions in the
ST60 Graphic Display Installation
Guide

The ST60 Graphic Display receives both data and power from SeaTalk. You

configurations, the instructions given here describe the general requirement.
Adapt these instructions, to suit your particular situation.
A range of Raymarine SeaTalk extension cables and Raymarine 3-way
SeaTalk junction boxes are available to provide maximum flexibility when
installing your display.
Optional connections

connectors provide a useful means of
communicating with external systems, but you can carry out all basic
operations without making any NMEA connections.

Graphic Display, ensure that the system with the display included, will
