READY

-

This

input

line

is

a

data

source

signal

indicating

that

the

data

source

is

open

for

communication

and

can

accept

or

transmit

data.

In

this

status,

the

signal

should

be

at

the

MARK

level.

Normally,

in

the

printer,

this

line

is

strapped

to

the

SPACE

level.

To

implement

half

or

full

duplex

opera-

tion,

this

trace

should

be

cut.

(See

figure

2-9.)

This

pin

is

not

inserted

in

J2

but

is

available

and

tied

back.

-

This

input

signal

is

a

data

source

signal

indicating

the

availability

of

the

data

source

to

receive

data.

It

is

expected

that

this

signal

is

normally

at

the

SPACE

level

and

shifts

to

the

MARK

level

when

data

can

be

received.

In

the

printer,

this

line

is

strapped

to

the

RTS

output

(MARK

level).

Users

requiring

half

duplex

operation

should

cut

the

strapping

trace.

(See

figure

2-9.)

This

pin

is

not

inserted

but

is

also

available

and

tied

back.

TTY

CURRENT

LOOP:

This

interface

system

provides

an

asynchronous

serial

bit

communi-

cations

mode

using

the

20/60

rna

current

loop

data

transfer

technique.

The

printer

has

facilities

for

both

receiving

and

transmitting

data.

(See

Figure

2-8

for

the

pin

connections

for

serial

connector

J-2.)

Data

transmission

timing

is

the

same

as

for

RS-232-C

communications.

2.10

OPTIONS

Only

one

standard

option

is

applicable

to

the

Model

DP-9000/

DP-9500

or

DP-900l/DP-950l

Printers:

Option

R

(FIFO

buffer

expansion).

This

option

may

be

installed

by

the

factory

at

time

of

order,

by

the

dealer

at

time

of

sale,

by

an

Authorized

Anadex

Service

Center,

or

by

the

user

at

any

time

after

pur-

chase.

When

the

option

is

ordered

separately,

installation

instructions

will

be

provided

with

the

option

hardware.

2.10.1

OPTION R:

This

option

expands

the

FIFO

Random

Access

Memory

(RAM)

buffer

from

the

nominal

600

characters

standard

memory

to

a

nominal

2.7K

character

FIFO

buffer.

This

option

is

particularly

useful

in

graphic

printing

and

applications

requiring

transfer

of

large

blocks

of

data

without

"handshakeo

signals

such

as

CRT

dumps,

etc.,

or

where

it

is

desirable

to

transfer

a

large

block

of

data

and

allow

the

data

source

to

perform

additional

processing

while

the

printer

is

printing.
