Limited warranty policy
Northstar Technologies, Inc. warrants the Northstar 958 to be free from defects in materials and
workmanship for a period of two (2) years. This warranty applies to the original purchaser and to any
subsequent owner during the warranty period, which begins on the date of shipment of the unit,
F.O.B. Acton, Massachusetts, to an authorized Northstar dealer.
Systems may not be returned to Northstar without a Returned Materials Authorization (RMA) number. Call the Northstar dealer or Northstar for instructions.
During the unit’s warranty period, Northstar will repair or replace, at its option, any part of the unit it
finds to be defective due to faulty material(s) or workmanship. All such repairs and/or replacements
will be promptly performed by Northstar free-of-charge to the owner, excluding freight costs
incurred in shipping to the factory. Return shipments from Northstar to points within the United
States are made via ground transportation, freight prepaid. Special shipping charges (overnight,
two-day, and so on) are the responsibility of the owner.
To be covered by this warranty, the Northstar equipment must have been in normal use. This warranty does not apply to units with defects caused by improper installation, physical damage, abuse,
tampering, lightning or other abnormal electrical discharge, or to units with defaced or altered serial
numbers, or to units repaired by unauthorized persons or repaired in a manner that violates Northstar’s recommended service procedures.
All repairs and/or replacements made under this warranty must be performed at Northstar’s facilities
in Acton, Massachusetts. Performance of warranty work elsewhere will not be authorized, and Northstar will not pay for any charges for such work. Northstar will not be responsible for payment of any
charges imposed by a Northstar dealer or other party for services requested by and/or performed for
a unit’s owner in connection with this warranty. Such services might include removal of the unit
from a vessel, inspection, packaging, handling, reinstallation, and the like.
Northstar Technologies assumes no responsibility for any consequential losses of any nature with
respect to any of its products or services sold, rendered, or delivered. The foregoing is the only warranty expressed or implied. No other warranty exists.

SECTION ONE: Introducing the 958
Checking the 958 package
The Northstar 958 is a full-featured color GPS navigation system that you can connect to a wide
variety of optional equipment, including the Northstar 490 echo sounder; Northstar radar; and VGA
output equipment, such as the Northstar 1201 remote display. Other optional interfaces include any
NTSC-compatible video input equipment, such as a video camera, TV, DVD, or VHS, and the optional
Northstar 2701 DGPS/WAAS receiver (instead of the 2201 or 2301) for WAAS/GPS/radiobeacon
differential. For installation instructions for the Northstar 490 or Northstar radars, see the Northstar
490 Installation Manual (P/ N G M491) or the Northstar Radar Installation Manual (P/N G MK R adI M).

SECTION TWO: Installing and wiring the 958
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 958’s voltage rating
of 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 958.
Bench-testing the 958
Northstar recommends bench-testing the 958 before installing it onto the vessel. Bench testing
ensures that the equipment is fully operational, and lets the 2201/2301 antenna or 2701 beacon
receiver collect the current almanac and ephemeris data for the installed location, which results in
less on-board installation time.
Mounting the 958
CAUTION!
Proper installation of the Northstar 958 is critical to accurately receive
and effectively use GPS/WAAS signals under a wide variety of weather
conditions.
Keep the following safe compass distance from the 958: 1.0m
standard, 0.8m steerin g.
Choosing the best 958 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 958 out of direct
sunlight. See the figure below for additional mounting recommendations.
958 Installation Manual, Rev. A1 Page 3
SECTION TWO: Installing and wiring the 958
Regardless of the type of mounting, the 958 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 958 is
yoke-mounted low, tilt the
958 back for best
viewing contrast.
Figure 1: Mounting recommendations
Page 4 958 Installation Manual, Rev. A1
SECTION TWO: Installing and wiring the 958
Flush-mounting the 958
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 958 to overheat, which, in turn, may
cause the display screen to darken. For overall width and height requirements, see the Northstar 958
Flush-Mounting Template (P/N GT958), which you can use to drill the mounting holes and cut the
mounting panel in the exact recommended locations.
CAUTION!
When flush mounting, be sure to mount the 958 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 ca se and compromise its waterpr oof sea l. This
type of physical damage will void the warranty.

Wiring the 958
Avoiding cable wiring shortcuts
Most installation problems are caused by shortcuts taken with system cables. When wiring the 958,
follow the guidelines in Figure 4 and Figure 5 below.
DON’T DO THIS!
Don’t make sharp bends in the cables
Page 6 958 Installation Manual, Rev. A1
Don’t run cables in
a way that allows water to flow down

.
DO THIS!
•
Do make drip and serv ic e lo ops
•
Do tie-wrap all cab l es t o ke ep 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 958

Electrical power requirements
Power source
The 958 is a negative-ground system that’s reverse-polarity protected. Power requirement is 10 VDC
minimum to 36 VDC maximum with at least 16-gauge connecting wire.
CAUTION!
As a good safety practice, Northstar strongly recommends
that you connect the 958 to a circuit breaker or 20-amp fuse
at the power source (battery).
Connecting the 958 to ship’s power
The 958 ships with a 10-foot power cable that you can lengthen 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
Page 8 958 Installation Manual, Rev. A1
SECTION TWO: Installing and wiring the 958
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
American Boating and Yachting Counsel specifications to find the correct fuse for 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. The power
cable has an inline fuse to protect the vessel’s wiring, and prevent electrical fires and damage to the
958. 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 958 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.
