INTRODUCTION TO GPSPLUS

The GPSPlus display unit processes the information from its
accurate 12 channel GPS antenna/receiver unit or from an
additional LORAN-C or DECCA receiver. The unit can
select between either of the two input devices to display
accurate positional information, along with waypoints, routes
and information concerning GPS satellites, LORAN-C T.D.'s
or DECCA L.O.P.'s.

The GPSPlus display has alarms that can be set and
adjusted to suit your requirements. When an alarm condition

will indicate which alarm has been triggered. When the
GPSPlus is part of a fully integrated Network Instrument
system the alarm conditions will be displayed and sounded
by all Network display units.

INTRODUCTION

After installation the GPSPlus can be used immediately with
minimal setting up for basic operation. To use the advanced
features of the GPSPlus display it is necessary to program
various parameters and enter waypoints and routes into the
units library. These will be discussed in later sections of this
handbook.

SWITCHING ON

The GPSPlus will power up and start receiving and
processing the signals from the satellites when the switch or
contact breaker for your instruments supply is turned on.
The display unit does not have an ON/OFF switch.

INITIAL DISPLAYS

On power-up the unit will show its satellite receiving status:

On subsequent power-ups the GPSPlus should quickly
obtain enough satellites for a fix, and the WAIT message
will only be displayed momentarily. If after a period of 15
minutes the display still shows NO DATA then check your
installation. If everything seems to be in order consult your
dealer.

The GPSPlus system requires only three satellites to obtain
a `fix'. When the unit has obtained a fix (in GPS mode) the
display will show the following:

If the GPSPlus display has not been programmed with any
navigational data (i.e. waypoints or routes) only the POS
key gives useful information.

When a brand new unit is powered up for the first time, or if
the unit has moved more than 1500km since it was last
powered up, it may take up to an hour to acquire enough
satellites for a fix.

Your GPSPlus has the ability to be used with a secondary
position fixing device, either a LORAN-C or a DECCA. The
unit will initially power-up using its own GPS
antenna/receiver unit. Selecting LORAN-C or DECCA
receiver will be explained later in this manual. Once
selected the GPSPlus will always power-up using the
selected receiver.

USING THE LIGHTS KEY

The GPSPlus display unit has 3 levels of illumination and
off, controlled by the LIGHTS key. It also changes the
illumination level of the key legends. The LIGHTS key is
always illuminated so even in complete darkness the key
can be located.

NOTES ABOUT ENTERING DATA

• When a number or name is flashing the ▼ STEP ▲ knob

can be turned to alter the flashing display, without the
need to press any other keys. To select the value that is
currently flashing, press the ENTER key.

INTRODUCTION TO WAYPOINTS

A "waypoint" is simply a point you wish to go to. It can be an
anchorage, a point off a landmark, buoys, harbour
entrances or any position at sea. Whatever the waypoint, it
is necessary to know its position in latitude and longitude or
determine its range and bearing from your present position.
This can be taken directly from your chart.

The GPSPlus display can store 250 waypoints in its
memory, this is commonly called a waypoint library. The
waypoints are given unique numbers, and can also be
named, so they can be recalled when required. After a time
your waypoint library will contain all your most commonly
used navigational points. The waypoints in the library can
be edited if required, i.e. copied, named and deleted. This
will be necessary if you have used all of the 250 waypoint
library locations. Until at least one waypoint has been
entered into the GPSPlus library defining a route the
advanced navigational features obtained by pressing the
NAV key are not available.

ENTERING WAYPOINT DATA

Waypoints can be entered into the waypoint library of the
GPSPlus unit in many ways. The following is a list of these
methods:

1. Mark facility, one-touch waypoint entry.

2. Entry of waypoint latitude and longitude.

3. Entry of present position as a waypoint.

4. Copying from a library waypoint to another.

5. Entry by range and bearing from another waypoint.

6. Copying or "uploading" from another position fixer.

NAMING WAYPOINTS

It is possible to give any waypoint a name. This could be the
charted name of buoys, navigational markers, or any unique
name you wish to use. The name must not exceed eight
characters in length and can be any combination of letters,
numbers, spaces and the symbols <, >, /. All spaces count
as characters. For example:

BUOY, <BUOY>, 123/BUOY, B U O Y
The following words are reserved for use by the GPSPlus

unit and can not be used as waypoint names:

INSERT DELETE START END

All waypoints can be named before or after their position
has been entered. This allows you to generate a list of
library names and then at a later date enter the latitude and
longitude. The waypoint library can be sorted and listed
either numerically (default) from WPT 1 to WPT 250 or
alphabetically by name. Setting this feature is explained
later.

TRANSFER OF WAYPOINT DATA

It is possible to copy the waypoint library from the GPSPlus
display to another or any NMEA device. This is called
"downloading". There are two methods which will be
explained later. The reverse process, when waypoints are
copied from another GPSPlus display is called "uploading".

10

MARK FEATURE - INSTANT WAYPOINTS

The Mark feature allows 20 waypoints to be entered by
using a single key, the MARK key. This enables pots, drift
nets, and other points of interest along your present course
to be instantly memorised. Pressing the MARK key enters
your present position as a MARK into a reserved area of the
waypoint library. These mark waypoints are automatically
allocated the waypoint library names MARK01 to MARK20
and are waypoint numbers

To enter a mark simply press the

The first press will display the waypoint
library, the second and further presses
enter the MARKS. This can be carried
out 20 times.

After all 20 mark library locations have
been used the LCD will show

MARKFULL.

WPT 231

to

MARK

key twice.

.

If the Marks are of particular interest then it is good practice
to copy them to other waypoint library locations, name them
for easy identification, and then erase the original MARK. By
erasing the original more MARKs can then be entered,
because once the MARK library locations are full no more
MARKs can be entered. These procedures are explained in
this section of the handbook.

MARKs can be used to define a route. If on a passage you
enter MARKs into the library, and then use them in the
correct order to define a route, they can be used in reverse
to lead the way home. These procedures are explained in
USING ROUTES, later in this handbook.

IMPORTANT NOTE

create a route ensure that the MARK latitude and longitude
is as you expect. If the MARKs have been erased and then
re-entered (by pressing the MARK key) the MARK latitude
and longitude will have changed and the route could be
entirely different. THIS COULD ENDANGER YOU, YOUR

CREW AND YOUR VESSEL. CHECK BEFORE YOU
ENGAGE THE ROUTE.

It is suggested that you use a table to record your MARK
waypoints, it will help you identify and record them in the
future. The following pages could be copied for this purpose
or a table of your own design could be used.

: If MARK waypoints have been used to

Mark waypoints can be used exactly like any other waypoint
that you have entered using the methods described in the
following pages.
