and

retrieval systems. A VISTA PLUS

contains

a

keyboard,

cathode

ray

tube

display screen,

control

and

refresh electronics,

and

one

of

several

data

interfaces.

In

addition,

the

V

1ST

A PLUS can

accommodate

a

number

of

optional

peripherals

and

Data Interface Modules

Each VISTA PLUS terminal

is

supplied with one

of

the

following customer-selected

data

interface mod-

ules as

standard

equipment.

Asynchronous Serial

Communication

Interface,

MUlti-Speed (1-103)

EIA RS-232C interface

to

modems,

couplers,

or

other

equipment.

Nine switch selectab

le

speeds (110, 150,

300,

600

,

1200,

1800,

2400,

3600,

4800

baud). Even,

odd,

or

mark parity bit, switch selectable.

Transmits

11

bits

at

110

baud,

10

bits

at

higher

speeds. Receives 10

or

11

bits. A

20

ma signal

output

is

provided

to

drive a

copying

device with

the

data

as

received on

the

data

line.

Asynchronous Serial

Current

Loop

(TTY)

Interface, Multi-Speed (1-104)

Provides

20

or

60

ma

current

loop

(TTY) interface

for

direct

connection

to

computer

or

other

equipment

at

distances

of

up

to

1000

feet

or

more. Switch

selectable speeds,

se

lectable parity

and

20

ma signal

to

copying

device are same

as

with 1-

103

interface.

Parallel Interface Line Driver (1-106)

A"ow

s transmission and reception

of

data

on para"el

lines

up

to

1000

feet

or

more

in

length.

Synchronous Serial Interface (1-107)

EIA RS-232C interface

compatible

with

Western

Electric 201 A

and

201 B

modems

.

Accepts

external

clocks

at

EIA levels.

Character

format

is

8-bit,

with

odd

character

parity.

Text

messages

followed

by

longitudinal

redundancy

check

(LRC)

character

.

Asynchronous Serial Interface

with

LRC (1-108)

EIA RS-232C interface

for

applications

which require

asynchronous

(1

O-bit)

character

format,

character

parity,

and

message

parity.

Character

parity

is

even.

Message parity

is

provided

by longitudinal

redundancy

check

(L RC)

character.

The

interface has

1200

baud

internal speed

and

an

external

clock

position

.

Asynchronous Serial Interface

to

Message

Concentrator (1-109)

Used

in

VISTA PLUS if

and

only

if

VISTA PLUS

is

connected

to

the

A-101 Message

Concentrator

. Trans-

mits and receives

data

at

9600

baud

in

asynchronous

format.

KEYBOARD

Layout

Keys

for

displaying characters are arranged

to

con-

form

with

the

proposed

ANSI

standard

for

keyboards

with logical

bit

pairing.

Rollover

When

one

key

is

already depressed

and

a

second

key

is

then

depressed,

the

code

for

the

second key will

not

be

generated

until

the

first key

is

released.

Repeat

When a

code

or

function-generating

key

is

depressed

for

more

than

0.4

second,

the

code

or

function

will be

repeated

at

a rate

of

10

per

second

.

INTRODUCTION

The

INFOTON

VISTA

PLUS

is

a

stand-alone

alphanumeric

display

terminal

for

use

in

data

entry

and

retrieval

systems

where

a

highly

flexible

interaction

between

man

and

machine

is

desired.

The VISTA

PLUS

incorporates

such

important

features

as

line

and

character

editing,

protected

fields,·

tabbing,

and

block

transmission

of

data.

In

a

typical

VISTA

PLUS

application,

an

operator

enters

data

on

the

screen,

visually

verifies

or

edits

the

data,

and

then

initiates

data

transmission

by

depressing

a

transmit

key.

The

VISTA

PLUS

is

ideally

suited

for

a

wide

variety

of

information

systems,

such

as

reservation

systems,

credit

~erification

systems

or

text

preparation

and

editing.

The VISTA

PLUS

is

functionally

different

from

the

INFOTON

VISTA

BASIC

and

VISTA

STANDARD,

which

are

teletype-compatible

terminals

that

transmit

each

character

as

its

key

is

depressed.

With

the

VISTA PLUS, a

computer

may

send

messages

to

define

protected

fields;

the

operator

may

enter

and

edit

data

in

any

unprotected

field

on

the

screen

prior

to

block

transmission.

A VISTA

PLUS

consists

of

a

keyboard,

cathode

ray

tube

display

screen,

refresh

electronics,

and

one

of

several

data

communications

interfaces.

Furthermore,

several

optional

features

are

available

\vith

the

VISTA PLUS.

These

options

include

a

magnetic

tape

cassette

storage

unit,

electronics

to

drive

a

printer,

a

light

pen,a

built-in

modem,

and

a

polling

module

which

allows

more

than

one

VISTA

PLUS

to

be

attached

to

the

same

communications

line.

The

VISTA

PLUS

may

be

incorporated

into

many

system

configu-

rations.

In

a

local

environment,

the

VISTA

PLUS

may

be

connected

to

a

computer

without

modems;

in

a

remote

environment,

the

VISTA

may

be

connected

CHAPTER

PRINCIPLES

OF

OPERATION

VISTA

PLUS

DESIGN

A

system

block

diagram

of

the

VISTA

PLUS

is

shown

in

Figure

2.

The

video

generator

logic

provides

video

signals

that

display

on

the

screen

the

images

of

the

characters

stored

in

the

memory.

In

addition,

a

blinking

underscore,

called

the

cursor,

is

always

displayed

on

the

screen.

The

cursor

marks

the

character

position

at

which

the

from

the

keyboard,

from

the

data

line

or

from

the

option

interface

will

be

displayed.

The

characters

presented

on

the

screen

should

be

thought

of

as

an

image

of

the

contents

of

the

internal

memory

of

the

VISTA PLUS.

When

a

character

is

entered

into

the

memory,

the

image

on

the

screen

is

automatically

updated.

The

details

of

the

method

whereby

a

character

is

inserted

at

the

proper

position

of

the

circulating

MOS

shift

register

memory

need

not

be

considered

by

a

user

of

the

VISTA PLUS.

In

fact,

the

only

access

which

the

system

user

or

designer

has

to

the

internal

memory

of

the

VISTA

PLUS

is

through

the

keyboard,

the

data

interfaces,

or

the

option

interfaces

'supplied

by

INFOTON.

A

specification

sheet

for

the

VISTA

PLUS

is

contained
