SAFETY WARNING

The terminal power cable

is

supplied with a safety ground. Do not use the
terminal with an ungrounded outlet. Disconnect the power cable from the termi­nal before removing the top cover for any reason.

Dangerous voltages are present when the terminal

is

on and may remain after the

power

is

off. Be extremely cautious. Do not work alone.

The internal phosphor

of

the

CRT

(cathode ray tube)

is

toxic. Wear safety goggles

and rubber gloves whenever the CRT

is

handled. If the tube breaks, exposing skin

or

eyes to the phosphor,

immediat~ly

rinse the affected area with cold water and

consult a physician.

This equipment generates, uses, and can radiate radio

frequency energy and

if

not installed and used in accordance with the

INTRODUCTION

To

use this guide effectively, you should already

have

a hasic

working

knowledge

of

ANSI

alphanumeric

terminals such as the

DEC

VT-IOO.

WY-7S VIDEO DISPLAY TERMINAL

Introduction 1

INSTALLATION

Please read the following procedures and precautions before turning on the
terminal.

1.

If

you have not already unpacked the terminal, carefully remove it from the
container. Save all packing materials in case the terminal must be shipped
or stored.

Caution: Sharp instruments should not be used

to

open the container.

Immediately notify the transfer company, if there

is

any damage.

2.

Place the terminal on any sturdy table or desk.

3. Set the

ON/OFF power switch on the front

of

the video module base

to

OFF

by pushing the bottom

of

the switch.

4. Connect the keyboard cable to its receptacle on the video module base.

5. First connect the power cord to its receptacle on the video module base.
Then plug it into a nearby three-pronged, grounded electrical outlet.

6. Connect the host computer communications cable

to

the modem port (see

"Connector Pin Assignments").

Note: All the connectors are keyed so that connections can only be made

in

the correct way.

The WY-75 has a female RS-232C connector that requires a male RS-232C

connector on the host interface cable. This

is

opposite the

VT-lOO

connectors.

7. Connect the printer communications cable, if required, to the auxiliary port.

2 Installation

POWER ON/OFF

After verifying that the terminal

is

properly installed, you are ready to proceed.

I. Turn on the terminal by pushing the top half

of

the ON/OFF switch.

2. Listen for

an

immediate beep. This indicates the power

is

on.

3. Watch for the cursor to display

in

the upper left-hand corner

of

the screen.

If the CRT were warm, you would first see the screen flash several display
patterns as the power-on self test

is

run.

4. Adjust the screen brightness with the thumbwheel intensity control on the
front lower right-hand corner

of

the video module. Turn it downward for

high contrast and upward for dim.

5. Swivel the video module left or right and tilt it

up

or down, until you find

your personal comfort level.
The recommended height for the center

of

the screen

is

10

to 20 degrees

below eye level. The keyboard should

be

at

or

below elbow height.

6. To shut

off

the terminal, just push the bottom half

of

the ON/OFF switch.

Power On/Off 3

SETUP PARAMETERS

The first time the terminal

is

turned on, a default setup controls the way it operates
for many variables called parameters. You can accept the default setup or choose
one

to

match your application program.

Whenever the parameters are changed, you can save the new choices

in

non-

volatile memory so they will be in effect the next time the terminal

is

turned on;

or you can easily return to the default setup, if necessary.
Caution:

Upon entering the setup, although screen data

is

preserved, all data

received from the host computer and any unprocessed data

in

the datacomm

buffer

is

lost.

ESCAPE CODE SEQUENCES

The following table briefly describes the actions perfonned by the WY-75 tenni-

nal when it receives

ANSI mode escape code sequences. Also listed

is

the ANSI,
DEC, or WYSE private mnemonic for the command. WYSE mnemonics begin
with

WY.

DEC mnemonics begin with DEC. All others are ANSI mnemonics.

Within the escape code sequence, parameter values are noted within angle brack­ets (e.g.,

<PO>

is

the first parameter; Pi signifies any legal parameter value).
