It is the owner’s sole responsibility to install and use the instrument and transducer/s in a manner that will
not cause accidents, personal injury or property damage. The user of this product is solely responsible for
observing safe boating practices.
The choice, location, and installation of all components in any autopilot system is critical. If installation is not
correct, the unit can not perform at its designed potential. If in doubt, consult your Northstar dealer. Ensure
that any holes that cut are in a safe position and will not weaken the boat’s structure. If in doubt, consult a
qualified boat builder.
Using the PILOT 3300 system :
The PILOT 3300 system is intended as an aid to save a helmsman from having to steer for long periods of
time, not as the main means of steering the boat.
The PILOT 3300 system is not intended for use in extreme weather, in adverse conditions or in water near
other boats, dangerous waters or land.
The PILOT 3300 system can not control the boat better than a helmsman. In adverse conditions steer the
boat manually.
Never leave the helm unattended. Keep a watch at all times. The helmsman should always monitor the
course of the boat and the PILOT 3300 system and be ready to resume steering the boat manually.

1-2 Using the PILOT 3300 system with other instruments
1-2-1 Using other instruments
The PILOT 3300 system can use data from these instruments:
GPS: A GPS or chartplotter, such as a Northstar 6000i chartplotter must be connected to the PILOT 3300 system
for the PILOT to operate in GPS mode (see the PILOT 3300 Reference manual).
Note: GPS must be via NMEA input.
WIND: A wind instrument, such as a Northstar WIND series, must be connected to the PILOT 3300 system
for the PILOT to operate in WIND mode (see the PILOT 3300 Reference manual).
SPEED: A speed instrument, such as:
Northstar’s MULTI with a paddlewheel speed sensor
or a GPS or chartplotter, such as Northstar’s 6000i series can be connected to the PILOT 3300 system to
increase steering accuracy.
Note: The speed from a paddlewheel sensor is the speed that the boat is moving through the water. The speed from
a GPS is the speed over the ground. If there is a water current then these two speeds will be different. If the PILOT
3300 system is connected to an instrument with a paddlewheel sensor and to a GPS, then the PILOT 3300 system will
automatically use the speed from the paddlewheel sensor instrument.
1-2-2 NavBus
NavBus is a Northstar proprietary system that allows systems of multiple instruments to be built using a single
set of transducers. When instruments are connected by NavBus:
If you change the units, alarms or calibration in one instrument, then the values will automatically change
in all other instruments of the same type.
Each instrument can be assigned to a group of instruments, called a NavBus group (see NavBus group in
the Setup > Comms menu, in the PILOT 3300 Reference manual). If you change the backlight in an instrument
in group 1, 2, 3 or 4 then the backlight will automatically change in the other instruments in the same
group. If you change the backlight in an instrument in group 0 then no other instruments are affected.
If an alarm sounds, mute it on any instrument which can display that alarm.
For more information, refer to the NavBus Installation and Reference manual.tt
Note: GPS must be via NMEA input.
NavBus and the PILOT 3300 system
The PILOT 3300 system will automatically work with additional PILOT 3300 displays.
The PILOT 3300 system can receive wind data from Northstar’s WIND over NavBus.
The PILOT 3300 system can receive speed data from Northstar’s MULTI over NavBus.

Reference Manual
1-2-3 NMEA
NMEA is an industry standard, but is not as flexible as NavBus as it requires dedicated connections between
instruments. The PILOT 3300 system has one NMEA input port and one port that can be configured to be an
input or an output (See PILOT 3300 Reference manual).
PILOT 3300 system NMEA inputs
GPS: The PILOT 3300 system can receive NMEA GPS data from a compatible GPS or chartplotter, such as
Northstar’s 6000i series chartplotter:
XTE (from APA, APB or XTE sentences) is required for the PILOT 3300 system to use GPS mode
BRG (from APA sentences) and BOD (from APA or APB sentences) are optional and improve performance
COG (from VTG sentences) is optional and can be displayed.
WIND: The PILOT 3300 system can receive NMEA wind data from a compatible wind instrument:
True or apparent wind direction (from MWV sentences) is required for the PILOT 3300 system to
use Wind mode.
SPEED: The PILOT 3300 system can receive NMEA speed data from a compatible paddlewheel or GPS
instrument:
SOG (from VTG sentences) is optional and improves performance.
Note: If the PILOT 3300 system is connected to a Northstar series wind or speed instrument using NavBus, then the PILOT
3300 system will automatically receive and use the wind or speed data, and the NMEA connection need not be wired.
PILOT 3300 system NMEA outputs
The NMEA 2 port can be configured to be an input or to be output:
either heading (HDG & HDT) and rudder angle (RSA) at once per second
or heading (HDG) at ten times per second
(see NMEA mode in the Setup > Comms menu, See PILOT 3300 Reference manual ).

Northstar NS3300 Pilot System Intallation
Power supply: The PILOT 3300 system requires two power supplies, both nominally 12 V DC:
A heavy duty supply for the steering drive
A light duty supply for the PILOT 3300 system electronics and display unit; this supply also powers any
additional display units and other instruments.
The power supplies require one or two switches and fuses or circuit breakers (see section 3-4).
Steering drive: The PILOT 3300 system can power a hydraulic pump, constantly running pump set, hydraulic
linear drive or mechanical drive rated at 12 V DC and up to 20 A.
Rudder linkage: To link rudder to rudder feedback unit (see section 3-5).
For wiring, see Select Wire Table in section 3-4-2.
External beepers or lights (optional ): The external output is switched to ground, 30 V DC and 250 mA
maximum. If the beepers and lights require more than 250 mA total, fit a relay.
Other marine instruments (optional): Wind, speed or GPS instruments can be connected (see section 1-2).
Other parts: For systems of several instruments, wiring and connectors are required. Northstar junction boxes
can simplify wiring several Northstar instruments together (see section 1-2 or the NavBus Installation and
Reference manual).
Coupling connectors and 10 m (33 ft)
extension cables are available to extend the rudder feedback unit,
compass or g yro cables. Do not fit more than one extension cable to each unit.

Northstar NS3300 Pilot System Intallation
3-2-2 Wiring guide
The PILOT 3300 system has two kinds of cables:
The heavy-duty power supply and steering drive usually require high-current cables:
Select the wire gauge from the wire size table (see section 3-4-2).
Fit high-current cables at least 1 m (3 ft) away from other electronic devices in the boat.
Keep the cables as short as possible.
Twin 2 mm (#14) cable is supplied with the PILOT 3300 system and can be used for the high current cable if
its gauge is suitable.
All the other cables are low-current:
Fit low-current cables at least 1 m (3 ft) away from sources of electrical signals or noise, such as the high-
current cables, other boat cables, engines, fluorescent lights, power inverters and radio or radar transmitters
and antennas.
If the cable for the rudder feedback unit, compass or gyro is too long, do not shorten the cable; instead coil
the cable up near the main control unit.
The cable for the rudder feedback unit, compass or gyro can be extended by adding a 10 m (33 ft)
extension cable and coupling connector. Do not fit more than one extension cable to each unit.
When fitting any type of cable:
Do not crush, pinch or strain the cable.
Secure the cable at regular intervals.
Ensure no connectors or exposed terminals are in the bilge.
This is a general guide for locating and wiring the parts of the PILOT 3300 system. The instructions for a
particular part may have additional requirements.
3-2-1 Location guide
Do not mount any part where it can be used as a handhold, where it will interfere with the operation of the
boat or where it might be submerged.
Do not mount any part where it will interfere with launching or retrieving
the boat.
Do not mount any part within 0.5 m (20”) of the plane of a radar antenna.
Mount the compass and gyro:
At least 1 m (3 ft) away from sources of electrical signals or noise, such as the batteries, high-current
cables, other boat cables, engines, fluorescent lights, power inverters, radio or radar transmitters and
antennas.
