Chapter 3: Installation

•
The transducer cable is fitted with spade connectors for direct con-
nection to the rear of the instrument. However, it may be necessary to
remove these to facilitate installation, e.g. if the cable has to be routed
through narrow apertures. Extra spade connectors are provided, to
replace any that are removed when running the cable. When fitting
spade connectors, prepare the cable as at (a) in the following illustra-
tion, then fold back the wire strands and insert into the spade connec-
tor as at (b). Ensure the wire strands do not extend beyond the rear of
the spade connector insulation, then crimp the connector to the wire.
Connecting the instrument
Types of connection
The ST60 Speed instrument, can be connected:
•
As a stand-alone, master instrument connected directly to the Speed
transducer.
•
As a SeaTalk repeater.
•
To fulfil both repeater and master roles by being connected both to the
transducer and to SeaTalk.
If instruments are connected to SeaTalk, 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 Raymarine 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.
