DAMAGE MAY

RESULT

IF AC POWER

IS

APPLIED

TO

THE

INSTRUMENT

WITHOUT

PROPER

INSTALLATION

OF

THE

VOLTAGE

SELECTOR

CARD

AND

THE

CORRECT

FUSE.

The

Model 5

Calculator

will

operate

on

a line voltage

of

either

120V

ac

or

240V

ac.

Input

power

tolerances (+8,

-16%)

permit

operation

within

the

ranges

of

101 V

to

130V

ac

or

202V

to

259V

ac.

The

line

frequency

must

be

within

the

range

of

48

to

66

Hz (inclusive).

NOTE

The

voltage

selector

card,

located

inside

the

power

module,

is

designed

to

enable

the

selection

of

two

additional line voltages -

100V

or

220V.

Because

of

the

input

power

tolerances, these

two

positions are

not

connected

in

the

power

module.

The

voltage

selector

card

can

be

installed

by

performing

the

following

procedure

(refer

to

Figure

2-1):

by

using a

sharp-pointed

object

(e.g.,

a ball-point pen)

to

pry

the

card

out

of

the

module.

4. Install

the

card

into

the

module.

The

MODEl50PTIONS

-.~-----------------------------------------------------

General

Information

The

Model 5

Calculator

is

intended

to

be a

system

which

would

be

ordered

by

a

customer

to

satisfy

his

specific

requirements.

For

this

reason,

it

is

expected

that

a

customer

would

usually

have

no

reason

to

add

to

his

system

after

the

original

purchase.

However, since a few

customers

may

wish

to

change

their

system,

this

presentation

provides

the

information

required

for

the

field

installation

of

Model 5

Options

which

are available

at

the

time

of

this

printing.

Refer

to

the

most

recent

IOSM for

future

options.

Keyblocks

cannot

be

ordered

by

the

customer.

Instead,

he

must

order

a

complete

accessory

kit

which

contains

all

of

the

assemblies necessary

to

redefine

his

system.

The

accessory kits

may

contain

a

keyblock,

a

PROM,

a

peripheral

and

an

interface,

or

any

combination

of

those

three

assemblies.

"Any

Some

keyblock

keys may require the

installation

of

other

devices (e.g., PROMs

or

peripherals)

to

operate

correctly.

The

keyblocks

(or

cover plate)

can

be removed

by

using the

access

hole

in

the

bottom

of

the

calculator

to

push the

keyblock

out

of

the

basket.

NOTE

Keyblocks

may

use

keys

which

define

a specific

customer's

routine;

thus,

the

keyblock

will

have a

unique

set

of

key

tops.

The

keyblock

may be

identified

by

label

on

INST

PROM Blocks

Programmable

Read-Only Memories are devices which are

unique

to

the

Model 5. Basically,

they

function

exactly

the

same

as

the

traditional

9S00-series

ROM

Blocks

except

that

each

PROM can be specially

'programmed'

at

the

factory

to

accomplish specific, predetermined

tasks (e.g., banking, finance,

or

car dealer

routines).

Also, since

the

PROM may

define

the

function

of

some

of

the

keyblock

keys, it may appear

that

the

keyblock

is

unique

to

a specific system. This

is

not

true,

as

the

keyblock

must

be

one

of

several available keyblocks.

All

PROMs require

the

use

of

a

keyblock,

but

their

operation

may also be associated

with

the

use

of

the

ST.RT key.

PRGM

A single

slot

is

located

beneath

the

printer

cover

for

PROM Block installation (see Figure

2-31.

Interface Cards

Figure

2-3

shows a Model 5 with

the

top

cover removed

and

indicates

the

interface card

PC

slots.

Up

to

3 cards can be installed

at

one

time.

We

recommend

that

the

cards be installed with

the

first card in

the

left-most slot,

with

the

associated I/O

connector

in

the

bottom

backpanel

position.

Future

installations can be accomplished

more

easily with

the

card and

connector

installed

in

those

locations.

CAUTION

CARE MUST

BE

TAKEN TO ENSURE

THAT

THE

I/O CABLE

IS

NOT DAMAGED

DURING

ITS INSTALLATION.

Display

(Option

367)

A display can be installed

in

the

Model 5

by

replacing

the

A40(09S05-66540)

Father

board

with

an A41 Display assembly

(09S05-66541)

(see Figure 2

-3).

Exchange

credit

for

the

A40

-\

assembly will

not

be allowed.

Optional

Data

Registers (Options

365

or

366)

The

installation

of

additional

data

registers may be required

by

either

a

data

register

option

(Options

365

or

366)

or

an accessory

kit

option.

If

no

data

registers have been previously

installed,

either

the

30(09S05-11366)

or

the

1

00(09S05-11365)

data

register assembly may be

installed in

the

single slot

to

the

right

of

the

I/O cards (see Figure

2-3).

If

the

unit

contains

the

30

data

register assembly,

the

100

data

register

(09805-11365)

assembly (only) can be installed

by removing

the

previously installed assembly

and

replacing it

with

the

Option

365

assembly.
