NCTIONAL DESCRIPTION.

The remainder

of

Section

I describes in more

detail

primary Display

Control-

ler,

Display

Station,

and

Printer Station

functions.

The Display

Controller

consists

of

an

interface,

central

control

and

symbol

generator

assembly, station

driver

assemblies,

printer

driver assembl

ies,

and may

contain

up to two

poller

assemblies.

On

diagrams and some figures

the

central

control

and

symbol

generator

assembly is referred to as CBU, station drivers as SDU's and

printer

drivers as PCU·s.

The

interface

enables

Display

Controller

communications with a 3000

Series

computer.

Two

cables

(up to 200

feet

long),

identified

as "All and "BII, provide the

data

link

between

the computer and Display

Controller.

Twisted-pair

signal

lines,

contained

in

cables

A

and

B,

are

described

under

interface

signals in

Section

III.

Symbol

generation,

timing, and

data

flow

gating

logic

are

contained

in

the

central

control and symbol

generator

assembly.

Video

pulse

trains,

representing

symbols,

are

developed

in

the

symbol

generator.

These pulse trains

are

made

availa-

ble

to

each

station

driver.

The station

driver

selects

the

proper pulse train and

transmits

it

to the

crt

where

it

is displayed by unblanking the beam in a 5 by 7

dot

matrix.

Symbol dimensions

are,

nominally,

1/8-inch

wide by

1/4-inch

high.

Each

station

driver

contains

logic

circuitry

controlling the

operation

of

a Display

Station.

It

receives

data

from

the

Display Station keyboard and the

central

control symbol

generator

assembly. All

data

sent

to

the

station

driver

is

stored

in

an assoc iated

Section I 3290 General Description

10-millisecond magnetostrictive

delay-line

memory. All stored

data

is

assembled

and decoded in

each

station driver, fed

to

the

Display Station, and displayed on

the

crt.

The display remains visible as long as stored

data

is

continually

refreshed

on

the

crt.

One

symbol requires

16.8

microseconds

to

display while one line

is

displayed

in

of

50 symbols,

therefore,

require

19.824

milli-

seconds allowing 9 symbol times for horizontal

retrace.

Thirteen lines

of

80 symbols

require

19.437

milliseconds.

A printer driver contains

the

Printer Station control

logic.

Data

from

the

station driver assembly register

is

translated and sent

to

the

printer

driver.

Printer

control and priority control logic

are

in

the

printer

driver.

One

Printer Station

can

serve as an output

device

for up

to

10 Display Stations if one

poller

is

used

or

it

can

be

used for an output

device

Each Printer

Station

contains

a

Selectric

* typewriter; depressing

the

PRINT

key

at

a Display

Station

activates

the

typewriter.

If

the

PRINT

keys

at

several Display

Stations associated with a Printer

Station

are

depressed

while

the

Printer

Station

is

busy

printing,

the

requests

are

processed in

is

designated

IIData

No.

111

** and

type

spacing

is

10 symbols

per

inch

in

a line with 6 lines

per

inch.

The

printer

uses a

black

fabric ribbon to

type

symbols

on

a

9-7/8-inch-wide

continuous strip

paper.

The paper

is

perforated for folding

and

tearing

at

ll-inch

intervals.

Feed holes

are

9-3/8

inches

apart

and

spaced

1/2

inch in

the

longitudinal

direction.

Printout

is

accomplished

at

the

following speeds: print

one

symbol,

64.5

milliseconds;

carriage

return,

129.0

milliseconds;

shift,

64.5

milliseconds; and

space,

64.5

milliseconds.

The Display

Controller

may

contain

a maximum

of

two

pollers.

Data

is

sent

to

or

from

the

remote stations

via

the

poller

in

8-bit

serial

codes.

The Data

Set

synchronizes

all

received

or

transmitted

data.

A

poller

controls

the

remote site1s

requests to transfer

data

by

periodically

polling (scanning) them

in

sequential

order.

ENVIRONMENTAL

CONDITIONS.

The Display

Controller

operates

at

normal room

temperature

but has a blower

assembly housing

located

beneath

the

logic chassis assemblies for

specific

cooling

of

the

logic chassis. The Display Stations and Printer Stations also

operate

at

normal

room temperature but

are

cooled

by

radiation

and

convection.

Tables 1-1 through

1-3

list

specific

environmental limitations for

all

three

units.

PHYSICAL DATA.

The

display

equ ipment

configuration

may consist

of

no more

than

12

Display

Stations,

Printer Stations, and

pollers.

No

more than two pollers may

be

employed,

so

the

maximum display equipment configuration

that

would

be

possible

locally

would

be

a combination

of

ten

Display Stations

and/or

Printer Stations with two

pollers.

The pollers are

capable

of communicating with up

to

16 remote Display

Controllers.

PROGRAMMING

This section describes programming aspects

of

the

display

equipment.

It

provides a complete description

of

signals, function and status codes, interrupts,

symbol

data,

word formats, various

read/write

operations, and programming aids

for both

interface

and poller assemblies.

INTERFACE

SIGNAL LINES.

The

Display Controller operates

from

the standard (12 bit) 3000 Series standard

communications

channels.

Figure 3-1 shows

the

interconnecting

data

and control

lines between the computer communications channel and the Display

Controller.

Following

is

a description

of

each

line

or

group

of

lines.

DATA

LINES

(12).

There are

12

bidirectional

data

lines.

During a read operation (input to the

computer), these

data

lines carry

data,

12

bits

at

a time,

from

the Display Controller

to the computer. During a

writ~

operation (output

fro~

the computer),· the

data

lines carry

data

from

the computer to the Display

Controller.

The

data

lines also

are

used to transmit the

12-bit

connect

and function codes associated with

Connect

and Function signals,

respectively.

PARITY

LINE.

A

parity

bit

accompanies

each

12 bits

of

data,

connect

code,

and function

code transmitted between the computer and the Display

Controller.

Odd

parity

is

used,

ie,

the total number

of

lis

transmitted

is

always an odd number.

CONNECT

LINE.

A

Connect

signal is

sent

to the Display Controller when a

12-bit

connect

code is

available

on the dato

lines.

The

li>isplay

Controller connects only

if

Display Controllers and

external

equipment controllers

associated with

that

communications

channel.

After a

delay

of

100 microseconds,

the communications channel

generates

its own internal Reiect

signal.

Once

a Display Controller

FU

NCTION LINE.

A Function signal is

sent

to the Display Controller when a

12-bit

function

code is

available

on the

data

I ines (function codes are listed under interface control

codes).

If

the Display

Controller

is

connected to the computer and is

capable

of

executing

the specified function

at

the time

it

receives

the

Function

signal,

it

initiates

the function and returns a Reply

signal.

If the Display

Controller

cannot

perform the function,

it

returns a Reiect

signal.

The Function signal and

12-bit

function code drop when a Reply or Reiect signal is

returned.

If

a Reply or Reiect

signal

is

not

returned within 100 microseconds, the computer

generates

its own

internal

reiect.

The specified function

is

not performed if a parity error exists on the function

code;

however, a Parity Error signal

is

returned by the Display

Controller

and the red

PARITY

error

indicator

on the Display

Controller

maintenance panel (figure

2-1)

lights.

Once

a function code is

accepted

by the Display

Controller,

all

other

function

codes

are

locked

out

until the first

one

is

acted

upon.

The Display Controller does

not

hold

or

stack up the function codes; a Reply or Reiect signal is returned within 5

microseconds. If a second function code is

received

which specifies the same function

as

the

previous function

code,

the second function code is

reiected

unless the function

can

be

performed immediately a second

time.

READ

LINE.

A Read signal transmitted to the Display Controller

directs

the

Display

Con-

troller

to begin reading

data

from

a specified Display Station memory.

The computer must first

to a

specific

Display Station before issuing

any interrupt

enable

function

codes.

Normally, status is

checked

immediately

following the

connect.

If

the computer desires to perform a

reset

operation

(function

code

0010),

or

a read

or

write

operation,

and wants to

be

informed when the

opera-

tion is

completed,

it

transmits function code 0022 (interrupt on end

of

operation)

prior to the

operation.

An

end

of

printout operation

can

interrupt the computer

if

the ready and

not busy interrupt is

enabled.

After

connecting

to a

specific

Display Station and

finding the station busy

executing

a

printout,

the computer has the option to

dis-

continue

the

printout

or

select

the interrupt on

ready

and not busy condition (function

code

0020).

Even though the function code is

directed

to a specific Display

Station,

it

enables

a station interrupt

from

any

Display

Station

satisfying the ready and not

busy

condition.

If

the computer wants to

receive

the

data

from

a local Display

Station,

func-

tion

code

0026 {station interrupt enable} is

transmitted.

An

interrupt transmits when

the SEND key on this

station,

or

any

other

Display

Station,

is

depressed.

Upon

receiving

an interrupt

from

the display

equipment,

the computer

nor-

mally

connects

to the Display

Controller

and

samples status to determine

what

caused

the

interrupt.

It

can immediately perform a read operation following a

connect

word having a

select

code

0000

if

the interrupt is a station

interrupt.

A write

opera-

tion

or

other

interrupt requires

connecting

to

a

specific

station before beginning the

operation.

After servicing an

interrupt,

the

interrupt

line may

be

cleared

by

reselecting

or

deselecting

the same interrupt

except

READ;WRITE

OPERATIONS.

Read

or write operations to or

from

a local Display Station may

be

performed

any time

at

the discretion

of

the computer, after checking

status.

The computer-

initiated

action takes priority over the

operator.

If

a read or write operation is

initiated

during a period when an operator is composing a message

from

the keyboard,

the operator1s keyboard is locked

out

and computer operation takes

over.

A read or

write operation to a Display Station performing a printout results in termination of

the printout and the read or write operation is performed

at

the specified Display

Station.

The Display Controller allows the computer to

enable

an interrupt on an end

of

printout

condition.

Following connection to a specific Display Station and

sampling status, print request status (line 3) is enabled

if

the Display Station requests

a print operation or

if

it

is presently performing a

printout.

Not

ready status

indi-

cates

the Display Station is

actually

performing a

printout.

Using function code

0020

octal,

the computer

may

enable

the

select

interrupt on ready and

not

busy

condition.

Upon completing printout, an interrupt is sent to the computer and status line 7

(ready and not busy interrupt) is made

active.

The

0020

function code enables an

interrupt to

generate

when any Display Station completes printout 0

Computer read and write operations do not take priority

in

the

poller.

The

poller scans the remote stations to determine

if

a SEND key

is

depressed.

If

this

condition exists, the selected station transmits a read message to the

poller.

After

storing the message

in

memory, the poller generates a send request and the computer

responds with a read

operation.

In response to the read message, the computer must

send a write message to the selected

poller.

The poller then relays this message to

the remote

station.

The

alert

function turns on the

ALERT

light and audible alarm

at

the remote

station; the SEND key must be depressed to tum them

off.

The subsequent read

message

enables

the computer to perform a write

operation.

Read

operations

may

be

initiated

from

the local or remote Display Stations

by an operator depressing the SEND key or

from

the computer by programmed

instructions (local Display Station

only).

A write operation is

initiated

only

from

the computer. Following is a description

of

read and write operationso

READ

OPERATION INITIATED

BY

A REQUESTING STATION.

A requesting station is a local Display Station

at

which a SEND key was

depressed, or a

poller

which

received

a read message

from

a remote

station.

At a

requesting station an end

of

message symbol is inserted

at

the entry marker

position,

I

the

entry

marker is moved to

the

upper

left

corner,

and a station interrupt is in

itiared

if

the

station interrupt is

enabled

by the

computer.

The computer responds

to

the

interrupt with a

connect

word

containing

a station

select

code

of

00

octal.

The

Display

Controller

then

connects

to the requesting station in scanning sequence and

activates

the status

lines.

The computer must perform a read operation to

clear

the send

request.

If

a read

operation

is not performed, the station interrupt is

sent

again

upon

receipt

of

the station interrupt

enable.

The station word (shown in

table

3-5),

containing

the number

of

the

scanner

selected

requesting

station,

is

sent

in response to

the

first Data signal during a

station-interrupt

initiated

read

operation.

If

the

selected

requesting station

is

a

poller,

the remote site and station

are

indicated

in bits 4 through

10.

Successive

words

after

the

station word

contain

data

stored in

the

delay

line starting

at

the

entry

marker

position.

When the end

of

message code is

detected,

it

is

sent

to the computer in a

data

word.

In

response to the

of

message

code,

the

End

of

Record signal

accompanied

by an

all-zero

data

word is

sent

instead

of

the Reply

signal.

The Read signal terminates the read operation and becomes

disabled for more than

200

nanoseconds. Data may therefore be read beyond the

end

of

message code

if

the Read signal remains

enabled.

local

Display Station or poller is not busy. Discretion is required in the use

of

After

connecting,

the entry marker may be moved to the upper left corner by

the

or

may

be left

at

its current

position.

In

response to the Read and Data signals,

data

words

are

sent along with

the

Reply

a specific station does

not

send the station word.

WRITE

OPERATION TO A

Data may be written into a connected station

at

any

time the station

is

not

starting

at

the position

of

the entry marker. A reset or

function

results in a

are

written into the

memory. The poller is informed

that

it

is to send the message when the Write signal drops. The

write,

message is sent to the remote station

wh

ich had iust previously sent

PROGRAMMING AIDS.

Following are several points concerning display equipment timing:

(a) The Display

Controller

is busy for 33 microseconds

after

the last Reply

signal is sent

at

the end

of

a write

operation.

(b)

The Display

Controller

is busy from

3.2

microseconds to

20

mi

lIiseconds

after

rece

ipt

of

a reset

function.

(c) If a read or write operation follows a reset function which transmits

an interrupt upon completion, 20-millisecond

delay

(after the end

of

operation interrupt

is

sent) occurs before the first

data

word

is

stored

or read

from

memory.

(d)

One

symbol time

is

16.8

microseconds. Each

data

word contains two

symbols and requires

33.6

microseconds. The

delay-line

memory

cycle

time

is

20 millisecondso During a read or write

operation,

successive

data

words must follow within 33 06 microseconds (time required to read

or write two symbols)

or

a 20-millisecond

delay

occurs between bytes

due to

delay

line

latency

characteristics.

PROGRAMMING RESTRICTIONS.

(a)

It

is necessary to read

at

least two

12-bit

words to

clear

the send ff

when a

connect

is issued

after

an

interrupt.

(b)

There should not be any unsolicited read or write operations (poller

only) •

(c) Sending an end

of

print message to a Display Station

initiates

operation

of

its associated Printer Station{s}.

Message.

The computer

cannot

directly

send a

mes-

sage to be written on a remote Display

Station.

It

can

indicate

to a remote display

equipment

that

the

computer has a message to be written by

initiating

an

alert

mes-

sage 0 The

alert

message is

initiated

by the computer as

an

alert

function to the

poller.

At the time the

poller

would normally poll a

site,

it

determines if an

alert

function was

rece

ived for

that

site.

The

poller

then sends an

alert

message instead

of

a pol'! message. The remote Display

Station,

upon

receipt

of

an

alert

message,

lights the

ALERT

indicator

and responds with an acknowledge message.

Polling 0

The following description

of

the

poller

operation assumes

that

no error occurred

while being transmitted

over

the

DATA-PHONE and

that

the remote site is operating

properly.

The

poller

is normally in a poll status during

wh

ich time

it

sends periodic and

sequential poll messages to the

sites.

If

a SEND key is depressed

at

a

site,

the

remote display equipment responds with a

read

message.

If

a SEND key

is

not

depressed, the remote display

equipment

responds with a

reject

message.

If

a read

message is

received,

it

is transferred to the computer as a message

from

a local

station would be

transferred.

The

poller

responds with a

reset-write,

write,

or

clear-write

message addressed to the Display Station

at

which the SEND key was

depressed.

The

poller

sends the message to

the

remote Display

Station.

The remote

display equipment responds to the

reset-write,

write,

or

clear-write

message with an

acknowledge

message which completes the communication 0

Reject

Message.

The

reject

message is a reply

from

a remote site to a poll message indicating

that

a SEND key was not

depressed.

The

reiect

message also

is

used to inform the

poller

that

the previous

write,

clear-write,

reset-write

or

alert

function was

not

performed. The

poller

interprets this as an

error.

Read

Message.

The read message is a reply

from

a remote site to a poll message

indicating

a SEND key was

depressed.

The

data,

read from the

crt,

begins

at

the

upper

left

corner and terminates with

the

data

subset

end

of

message

code

0 The read message

enables

send request status

and

the station

interrupt.

The computer then reads

the

site

address and station address in the station

word.

After

reading

the station word,

the computer may

continue

to read the rest

of

the

data

in

the

message

or

may send

a

write

message

immediately.

The computer reading a

data

word

clears

the send

request.

Write

Message.

The write message contains

data

from

the

computer to be written on the

crt

of

a remote Display

Station,

starting

at

the present

or

reset

entry

marker

position.

A

write,

reset-write,

or

clear-write

message is always

sent

in reply to a read message

(with

correct

parity)

from

a remote

site.

After

receiving

a write message with

correct

channel

from

the computer, the

poller

switches to transmit

trans-

fers the

data

to a remote

Acknowledge

Message.

If

the message is an

acknowledge

in response to an

alert

message,

alert

request and poll interrupt status

are

set.

The computer, upon reading status, is

informed

that

the

alert

message was

received

by the remote Display

Station.

An

acknowledge response to a

write,

reset-write,

or

clear-write

message turns the

indicator

off

and the poll ing resumes 0

ERROR

PROCESSING.

Errors may arise between the sending

of

a message to a remote site and

receiv-

ing a message

from

a remote site 0 The

poller

recognizes these errors:

(a)

lack

of

response before time

out

0

(b) Parity error in a

received

message 0

(c)

An

unexpected

response such as a read message in response to a write

message.

Programming 3290 Section III

Anyone

of

the error conditions causes the message to be retransmitted. The

message is transmitted up to three times

in

attempting to

get

an

error-free

response 0

If,

after

three transmissions, an

error-free

response

cannot

be

obtained,

the

poller

ceases trying to communicate with

that

remote

site.

If

three attempts to successfully communicate an

alert

message to a remote

display equipment

fail,

the Interrupt signal

is

enabled

and the

poller

resumes

poll

ing.

When the computer se lects the

poller,

poll interrupt,

poller

error,

and

alert

request status are

indicated.

Three unsuccessful attempts to communicate a

write,

write-reset,

or

clear-

write message to a remote site results in an Interrupt

signal.

Selection

of

the

poller

indicates

poller

error, station interrupt, and send request

status.

The computer must

then read the station

word.

The computer may reread the station word,

if

it

con-

tained a parity

error,

by reconnecting to station

o.

In

order to

clear

the status bits

and resume

polling,

it

is necessary

that

the computer send a release function 0

If

a poll message

cannot

be successfully communicated in three attempts,

the Interrupt signal is,

again,

enabled.

When the

poller

is

connected,

it

indicates

send request, poll

failure,

and station interrupt

status.

The computer then reads

the station

word.
