SAFETY INSTRUCTIONS
WARNING
Do not work inside the
equipment unless totally
familiar with electrical
circuits.
Hazardous voltage which can
cause electrical shock, burn
or serious injury exists inside
the equipment.
Turn off the power at the
mains switchboard before
beginning the installation.
Post a sign near the switch
to indicate it should not be
turned on while the equipment is being installed.
Fire, electrical shock or
serious injury can result if the
power is left on or is applied
while the equipment is being
installed.
CAUTION
Ground the display unit to
prevent loss of sensitivity
and mutual interference.
Confirm that the power supply voltage
is compatible with the voltage rating
of the equipment.
Connection to the wrong power supply
can cause fire or equipment damage. The
voltage rating appears on the label at the
rear of the display unit.
Use the correct fuse.
Use of a wrong fuse can cause fire or
equipment damage.
Keep the following compass safe
distances:

2. DISPLAY UNIT
The display unit can be installed with either of four methods as shown below. Refer to the
outline drawing at the end of manual.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the display unit away electromagnetic field generating equipment such as motor,
generator.
• Allow sufficient maintenance space and a sufficient slack in cables for maintenance and
repair.

3. ANTENNA UNIT
Mounting
Install the antenna unit referring to the installation diagram at end of manual. When
selecting a mounting location for the antenna unit, keep in mind the following points.
• Select a location out of the radar beam. The radar beam will obstruct or prevent reception
of the GPS satellite signal.
• Be sure the location offers a clean line-of-sight to satellite. Objects within line-of-sight to
a satellite, for example, a mast or funnel, block reception and cause prolonged acquiring time
or interruption of position fix.
• Mount the unit as high as possible. Mounting the antenna as high as possible keeps it free
of water spray, which can intercept reception of GPS satellite signal, if water spray is frozen.
• The antenna unit GPA-018S must be grounded. Connect ground wire of 1.25 sq or larger
(local supply) between the antenna unit and a stainless steel screw fastened to the mast.
• The antenna unit GPA-018S must be taped. See chapter 7 for instructions.
Extending Antenna Cable Length
The standard cable is 15m long. 30m and 50m long extension cable sets are optionally
available.

4. WIRING
Grounding
The display unit contains several CPUs. While they are operating, they radiate noise, which
can interfere with other radio equipment. Ground the unit as follows to prevent it.
• The grounding wire should be 1.25sq or larger.
• The grounding wire should be as short as possible.
External Equipment
The DATA1, DATA2, and DATA3 ports are used to connect an external equipment such as
autopilot, remote display, navigation equipment. Refer to the interconnection diagram on
page S-1 for connection of DATA1, DATA2 and DATA 3 port. The DATA4 port is used to
connect NMEA equipment, IBM-PC or DGPS beacon receiver as follows;

DGPS Setup
The default setting is "manual".
Automatic DGPS setup
The beacon receiver (GR-7000A) can automatically select optimum reference station by
feeding GP-90’s position data. If it takes more than 5 minutes to fix DGPS position at the
automatic mode, switch to manual mode. Use the manual mode when an external beacon
receiver has no automatic function of station selection.

correction data. In this time, position
fixing is done by using past position data.
When the ship is in the service area of a
beacon station, this value should be 21 or

• Check the grounding.
• Check the radar beam interference.
• Check the noise of power generator of
the ship.

5. INITIAL SETTINGS
Input/Output Setting
The GP-90 can output navigation information to external equipment. For example, it can
output position data to a radar or echo sounder for display on their display screen. You can
convert a Loran Plotter to a GPS Plotter with position data from the GP-90.
Before selecting data to output, confirm what data the external equipment requires. Output
necessary data only. Outputting unnecessary data can cause receiving problems at the
external equipment.
Talker
All data transmitted by marine electronics equipment is prefixed with a two-character code
which tells external equipment what equipment is transmitting data. This two-character code
is called the talker. The GP-90 contains the talkers GP, LC and DE.
Because GPS is a relatively new system some early model equipments do not recognize
the GP talker name. In this case transmit data using a conventional talker, which equipment
recognizes, such as Loran C.
