Safety
SECTION TWO: Installing and wiring the 957
considerations
WARNING!
Before starting the installation, be sure to turn
power off. Further, Northstar highly recommends
keeping power off while you’re installing the
system. If power is left on or turned on during the
installation, fire, electrical shock, or other serious
injury may occur.
Be sure that the voltage of the power supply is
compatible with the 957’s voltage rating—10 to 36
volts DC. Connecting to the wrong power supply
can cause fire or damage to the equipment. Be
sure to ground the equipment to prevent electrical
shock and mutual interference.
Be sure to use the proper fuse. Using the wrong
fuse can cause fire or damage to the 957.
957 Installation Manual, Revision C1 Page 5
SECTION TWO: Installing and wiring the 957
Bench-testing the 957
CAUTION!
CAUTION!
Northstar recommends bench-testing the 957 before installing
it onto the vessel. Bench testing ensures that the equipment is
fully operational, and lets the 2201 antenna or 2701 beacon
receiver collect the current almanac and ephemeris data for the
installed location, which results in less on-board installation
time.
Make sure that the 957 doesn’t interfere with any
other on-board systems. Check all other systems to
ensure that their performance doesn’t degrade
when the 957 is turned on.
Proper installation of the Northstar 957 is critical to
accurately receive and effectively use GPS/WAAS
signals under a wide variety of weather conditions.
Mounting the 957
Choosing the best location Choose the mounting location carefully—before you drill or cut.
The display screen is high-contrast and anti-reflective, and is
viewable in direct sunlight, but for best results, install the 957
out of direct sunlight. See the figure below for additional
mounting recommendations.
Page 6 957 Installation Manual, Revision C1
SECTION TWO: Installing and wiring the 957
Regardless of the type of mounting, the 957 should be installed in an accessible location
(dry) where the operator can easily use the controls and clearly see the display
screen. Be sure to leave a direct path for all of the cables.
Regardless of the type of mounting, the location should have minimal
glare from windows or bright objects. If the 957 is
yoke-mounted low, tilt the
957 back for best
viewing contrast.
Figure 1: Mounting recommendations
957 Installation Manual, Revision C1 Page 7
SECTION TWO: Installing and wiring the 957
CAUTION!
Keep the following safe compass distance from the
957: 1.0m standard, 0.8m steering.
Flush-mounting the 957 When flush mounting, leave at least two and a half inches of
clearance space behind the mounting panel for all of the
cables and connectors.
Flush mounting requires good ventilation behind the
mounting panel. Poor ventilation will cause the 957 to
overheat, which, in turn, may cause the display screen to
darken.
Figure 4 below shows the overall width and height
requirements for flush-mounting the 957. For further details,
see the full-size Northstar 957 Flush-Mounting Template (part
number GT957). This template should be used to drill the
mounting holes and cut the mounting panel in the exact
recommended locations.
CAUTION!
When flush mounting, be sure to mount the 957 on
a flat surface. Mounting on a curved surface can
break or distort the plastic and break the waterproof
seal.
Do not overtighten the mounting screws; you may
damage the case and compromise its waterproof
seal.
This type of physical damage will void the warranty.

SECTION TWO: Installing and wiring the 957
Yoke-mounting the 957 Before drilling, turn the 957 to the desired angle on the yoke to
make sure there’s enough space for the cables. Leave clearance
space as follows:
•
at least 2 inches of space all around the sides and the top
•
at least 2.5 inches of space in the back for all of the cables
and connectors
•
at least 2.25 inches of space in the front for opening and
closing the chart cartridge door and inserting and
removing a chart cartridge
For an illustration of the recommended clearances, see Figure 3
and Figure 4 on the following pages.

Avoiding cable wiring
shortcuts
Most installation problems are caused by shortcuts taken with
system cables. When wiring the 957, follow the guidelines
illustrated in Figure 5 below.
DON’T DO THIS!
Do not make sharp bends in the
cables
Do not run cables in such a way that
might allow water to flow down into the
connectors
DO THIS!
•
Do make drip and service
loops
•
Do tie-wrap all cables to keep
them secure
•
If cables are shortened,
lengthened, or re-terminated,
do seal and protect all wiring
connections
•
Do leave room at the back to
service the 957

Power source
The 957 is a negative-ground system that’s reverse-polarity
protected. DC power is required from a 10-volt minimum to a
36-volt maximum using at least 16-gauge connecting wire.
CAUTION!
As a good safety practice, Northstar strongly
recommends that you connect the 957 to a circuit
breaker or 20-amp fuse at the power source
(battery).
Connecting the 957 to
ship’s power
A 10-foot power cable is shipped with the 957 system. You can
lengthen this cable to a maximum of 25 feet:
•
for a cable length up to 15 feet, the power connections
must use 16-gauge connecting wire or heavier
•
for a cable length from 15 to 25 feet, use 14-gauge
connecting wire or heavier
If you lengthen the power cable, use an external fuse at the
battery end as an added safety precaution. The fuse size
should match the size of the wiring on the vessel. See the
NMEA or the American Boating and Yachting Counsel
specifications to find the correct fuse to use with your cable.
For the best protection from noise, connect the power cable
directly to the battery or dedicated electronics buss. The green
ground wire should be connected to ship’s ground directly.
957 Installation Manual, Revision C1 Page 15
SECTION TWO: Installing and wiring the 957
The power cable has an inline fuse to protect the vessel’s
wiring, prevent electrical fires, and prevent damage to the 957.
If you shorten this cable, be sure to keep the inline fuse intact.
The wires in the power cable must be connected as follows.
•
red → positive(+)
•
black → negative(–)
•
green → ship’s ground
NOTE:
Ground the 957 to the vessel to eliminate
interference. Without an earth grounding,
performance may be reduced. Secure the green
wire to the vessel’s nearest grounding point. If a
noise-free earth grounding point isn’t available, cap
and insulate the green wire—it shouldn’t be used
when an earth ground isn’t available, or with
systems using “floating” grounds.
Page 16 957 Installation Manual, Revision C1
SECTION THREE: Installing and wiring the 2201
Introducing the 2201
The Northstar 2201 GPS pod is a self-contained, high
performance GPS antenna/receiver that also receives Wide Area
Augmentation System (WAAS) differential correction signals.
When connected to the 957, the 2201 provides the 957 with
WAAS-enhanced GPS position information.
For the 2201’s technical specifications, see Table 15, “2201
technical specifications,” on page 64.
CAUTION!
Do not open the 2201: There aren’t any serviceable
parts inside. Unauthorized tampering will
automatically void the warranty.
