The NS3100 DEPTH comes in several configurations.

This Installation and Operation manual.
In addition, the standalone configuration usually
requires a depth transducer (see section 5-3).
One or more NS3100 series instruments will be
connected to the boat 12 V power supply via:
An accessory switch to turn the instruments on
and off.
A fuse. Use a 1 A fuse for between one and five
instruments.
The NS3100 DEPTH is usually used with a through
hull depth transducer. However, the unit can take
readings from another instrument, in which case it
may not need a transducer (see section 4).
A through hull transducer generally gives the best
performance and is the best choice for displacement
hulls. It is mounted in a hole drilled through the
bottom of the boat.
A plastic through hull transducer is suitable
for GRP or metal hulls. Plastic through hull
transducers are not suitable for solid wooden
hulls (use Northstar's bronze transducers).
These accessories are available from your Northstar dealer.

Kit configuration
The NS3100 DEPTH is available in several kit
configurations with different grades of through hull
transducer, with:
The parts for the standalone configuration, listed
above.
Through hull depth transducer.
Transducer Installation manual.
Optional external beepers or lights can be fitted. The
NS3100 DEPTH output is switched to ground, 30 V
DC and 250 mA maximum. If the beepers and lights
require more than 250 mA, fit a relay.
For systems of several instruments, wiring and
connectors are required (see section 4 or the NavBus
Installation and Operation manual).
A bronze transducer is suitable for
wood or fibreglass hulls. Never install
a bronze transducer in a metal hull,
because it will cause electrolytic
corrosion.
A range of Northstar through hull
transducers are available, plus in hull
and transom mount transducers. For
more information, refer to the Transducer
Installation manual or consult your
Northstar dealer.
