1-6 Main Unit

Attaching a Monitor

The

A1200

has

three

display

outputs,

allowing you to

use

any

of

several

kinds

of

display

devices:

• VIDEO port:

analog

RGB

monitor

(multiscanl15

KHzNGA);

television

with

SCART connection

• COMP.

jack:

composite monitor;

television

(using

VCR video

input)

RF MODULATOR jack: NTSC television;

PAL

television

See

the

documentation

for

your

monitor

and

any

other

graphics

expansion

hardware

you

may

have

for

specific

information

about

making

the

proper

connections.

Appendix A has

more

information

on

monitor

compatibility.

Your

dealer

can

help

you choose

the

right

combination

of

graphics

hardware,

monitor,

and

monitor

cable

or

adapter

for

your

use.

After

connecting

your

monitor,

skip

ahead

to

the

section

"Connecting Power

and

Turning

On the

Amiga"

if

you

have

no

optional

equipment

to

install.

Power

connection

is

always

the

final

step.

RGB Monitors

An RGB

monitor

gives

the

highest

quality

picture,

and

allows

you

the

widest

selection

of

the

Amiga's

many

display

modes.

Several

types

of

analog

RGB

monitors

can

be

used

with

the

A1200,

including

multiscan,

15 KHz,

and

VGAlSVGA monitors. A

multiscan

(multiple

horizontal

scan

rate

or

"multisync") RGB

monitor

provides

the

greatest

flexibility. A

multiscan

monitor

is

required

if

you

wish

to

use

display

modes

that

have

different

horizontal

scan

rates.

A 15 KHz

analog

RGB

monitor

can

display

only

the

Amiga's

default

display

mode

and

other

15 KHz

scan

rate

modes. A VGA

or

SVGA

type

monitor

can

display

the

Amiga's

de-interlaced

and

higher

resolution

modes,

but

not

the

standard

15 KHz video modes.

Main Unit

1-7

Connect

a 15 KHz

monitor

with

a 23-pin

female

connector,

such

as

the

Commodore 1084

or

10848,

directly

to

the

A1200

VIDEO

port.

For a monitor

such

as a multiscan,

VGA,

or

8VGA model

that

has a small

15-pin VGA-style

connector, connect

the

23-pin to 15-pin

adapter

included

with

the

A1200 to

the

VIDEO

port,

then

connect

the

monitor

cable

to

the

adapter.

With

the

proper

adapter

cable, a television

with

a SCART

input

can

be

used

as

a 15

KHz

RGB monitor. See

the

"SCART

Televisions"

section

below for

more

information.

Composite Monitors

o

Use a connector

cable

with a male

RCA-type

plug

at

one

end

~

and a plug

compatible

with

your

monitor

input

to

connect

a

composite

monitor.

Plug

the

RCA

end

into

the

Amiga's

composite

output

jack

(labelled COMP.)

and

the

other

end

into

the

composite

input

jack

on

the

monitor.

You

can

also

plug

this

end

of

the

cable

into

a VCR

that

has

a

composite

input

(usually

an

RCA-type

jack

labeled

VIDEO

IN

or

EXTERNAL

VIDEO).

This

allows you to record

Amiga

output

onto

video

cassette

and

use

a television connected to

the

VCR for

the

Amiga

display.

This

method

provides a higher

quality

picture

than

using

the

RF

modulator

output

to connect to

the

VCR

or

television

antenna

inputs.

However,

only

the

standard

15 KHz

display

modes

can

be

displayed

this

way.

An

RGB

monitor

is

required

to

properly

reproduce

the

Amiga's

de-interlaced

and

higher

resolution

display

modes.

NTSC Televisions

Connecting

an

NTSC

television

requires

a computerlTV

switch

box

and a connector

cable

with

male

RCA-type

plugs

at

both

ends.

If

your

television

reception

is

through

a coaxial cable

with a round

"F"

connector

you

also

need

a 75-ohm

to

300-ohm

adapter.

These

items

are

available

from

any

department

or electronics store.

1-8

Main Unit

If

you

have a VCR

or

television

set

with

a composite video

input

(an

RCAjack

usually

labeled

VID~O

IN)

you

should

use

the

composite

output

as

described

in

the

"Composite Monitors" section above.

This

is

simpler

and

produces a better

picture.

If

your

TV

or

VCR

has

antenna

inputs

only,

use

the

following

procedure:

1.

Disconnect

the

cable

or

VHF

antenna

wire

from

the

TV

or

VCR.

2.

For

coaxial cable:

connect

the

end

of

the

cable

to

a 75-ohm

to

300-ohm

adapter.

3.

Connect

the

VHF

antenna

or

adapter

leads

to

the

CONNECT

TO

terminals

on

the

switch

box.

4.

Connect

the

short

twin-lead

wire

on

the

side

of

the

switch

box

to

the

VHF

terminals

on

the

TV

or

VCR.

5.

Plug

one

end

of

the

connector cable

into

the

RF

MODULATOR

jack

on

the

Amiga.

6.

Plug

the

other

end

of

the
