Connecting the instrument

4. Place the Auxiliary Alarm in position with the foam seal between
it and the mounting surface, and secure it using the four self-
tapping screws (supplied).
5. Connect a 2-core cable to the connector block and run the other
end of the cable to the rear of the ST60 Multi instrument. The
manner in which you run the cable will depend on the locations
of the Auxiliary Alarm and instrument, but however you run the
cable, observe the following guidelines:
• If the cable has to be fed through the deck, always use a
proprietary deck gland.
• Where cables are fed through holes, always use grommets to
prevent chafing.
• Secure long cable runs so they do not present a hazard.

Introduction

The ST60 Multi instrument is connected to SeaTalk as a repeater, and
derives its power directly from SeaTalk so that no separate power
connection is necessary. Where a SeaTalk system includes an
autopilot, the power for the system is provided by the autopilot.
A range of Raytheon SeaTalk extension cables is available to connect
separated instruments. These cables are supplied with a SeaTalk
connector fitted to each end. A junction box can be used to join cables.

Connection options

Connection to SeaTalk is mandatory.
The NMEA connectors can remain without any connections or can be
used in one of two ways:
• You can connect for communication to and from NMEA (see
Chapter 1, Operation for details of the functions supported).
• If the Auxiliary Alarm option is fitted, the NMEA out terminals
provide the alarm signals to the buzzer.

Signal connections

Make the necessary connections to your ST60 instrument (see the
Connection to ST60 Multi instrument illustration).
