The prudent mariner

will

never rely solely on any single means of

navigation.

He

will

always

use

whatever information

available.

The Global Positioning System

(GPS)

is

developed and operated by

the United States Department

of

Defense (DOD).

Only partof the

system

is

available

for

civil applications.

The

expected position accuracy

is

better than

100

meters for

95

percent

of

the time; but may be up

to

300

meters occasionally. The derived

speed

and

course readings may

be

hampered

accordingly.

The availability and precision

will

be

kept within the stated

limits

as

far

as

the

military

and

political situation

allows.

The

MK8

and

MK9

are

preparedfor direct connection

to

a

DGPS

Beacon Receiver

(Philips

PBR

1000).

The

MK8

will for this purpose

need

a

DGPS

software upgrade and a new interface cable allowing

data

input. The position accuracy

is

hereby improved to better than

5

meters

for

95%

of

the time subject to availability

of

DGPS

transmissions

from

public Radio Beacons.

Please

notethat

a

position obtained from a chart

is

not always

as

accurate

as

The

MK8

&

MK9

Navigators are designed for installation both above and below

deck. The

unit

I

S

fully splash proof

but

not watertight. The installation should

in

the

first instance meet the requirements of

the

heimsman

or

the crew,

but

secondarily the site should be a smooth and flat nearly vertical surface to

insure

that

the

gasket around the holes for connection plugs and fixing screws

are waterproof. Please ensure that the navigator

is

mounted

in

a place where

water easily flows

off.

Never install

it

in

a place where the navigator

will

be

below

water

for

any

period

of

time.

Two

installation accessories

are

optionally

available:

A

Flush Mounting

Kit

and a Mounting Bracket (please see the chapter

containing technical data page

The

12V

or

24V

battery supply,

but

the

unit

will

work

with

any

DC

voltage from

9.6V

to

32V.

The installation kit includes a

9

socket

D

-

SUB

connector mounted

with

all the

necessary cabling. The Power Cable is a joint

RED

and BLACK pair:

BLACK wire (D

-

SUB socket

51

should be connected to the minus

pole

of

the battery.

RE5

wire (D

-

SUB socket

9)

should be connected to the plus pole of the

battery.

Please be sure to have a fuse

in

the circuit

-

not to protect the navigator

-

but

to protect

the

cabling. (Short

-

circuiting

a

cable with direct connection

to

a

battery

will

make severe damage).

A

typical installation

is

The electronics

of

the navigator

is

isolated

from

the external power supply.

It

is

recommended

to

ground the shield

of

the navigator

to

avoid static charge

built

up.

This can

be

done

in

one

of

two ways:

1)Connect

the

D

-

SUB

'GND'

1

of

the

navigator

to

boat's seawater

ground.

2)Connect the antenna mounting

(nut

etc.) to the boat's seawater

ground.

'Seawater ground' is any structure

in

connection

with

the sea below the water

-

line. The connection could be through

a

10

KOhm resistor.

Antenna mounting

and

navigator shield

is

electrically connected through

the

screen

of

the antenna cable.

To

avoid current loops do only

use

one

of

the two

grounding methods.

If

the antenna

is

mounted on the push

pit

or

similar metal

structure

we

recommend using that

part

for

grounding of the navigator

(possi

-

bly

by connecting

it

to

boat's

seawater ground).

is

either

a

or

a

joint GRAY pair with one wire marked

with

a

black stripe.

The

should

be

a

is

normally

the

and

The

NMEA

Standard provides

for

asynchronous transmission,

with

a single

TALKER

and

multiple

LISTENERS

per line. Typical use includes information

transfer from

oicclr

onic positioning and navigational devices to autopilots,

plotters, terminals, printers, etc.

The

NMEA

uses

protocol,

that

is

not

compatible

with

the

NMEA

0780

simple

format or

the

plex format due to differences

in

Data

Format.

Data are transmitted

in

different sentences, each containing one or more data

fields.

A

field consists of a string of characters immediately preceded

for

the

which

is preceded

by

"5".

The

data

fields

are

identified only by their position within the sentence as

determined by

the

field delimiters (comma).Numerical data fields within

a

sentence may vary

in

length

from one sentence to another, depending on

the

precision available.

Data

field position

is

therefore determined only

by

counting

'I,"

(commas) rather

than counting the total number of characters from beginning of the sentence.
