Transducer Installation manual.
5-2 Other parts required
One or more 310 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.
Optional external beepers or lights can be fitted.
The Explorer D310 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).
5-3 Transducer
The Explorer D310 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).
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.
