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 termi-
nal 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.

FCC NOTICE
WARNING: This equipment generates, uses, and can radiate radio
frequency energy and
if not installed and used in accordance with the
instruction manual, may cause interference
to radio communications. It has
been tested and and found to comply with the limits for a Class A
computing device pursuant to Subpart J of Part 15 of FCC Rules, which are
designed to provide reasonable protection against such interference when
operating in a commercial environment. Operation
of this equipment in a
residential area is likely to cause interference in which case the user at his
own expense will be required to take whatever measures may be required
to correct the interference.
Only devices certified to comply with the limits for a Class A computing
device may be attached to this equipment. Operation with non-certified
device(s) is likely to result in interference to radio and TV reception.
This equipment is intended for commercial use only and is not suited for
operation in class B environments.
The use
of shielded I/O cables is required when connecting this equipment
to any and all optional peripheral or host devices. Failure to do so may

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, ifrequired, 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.
1. Press SET UP to display the configuration fields.
2. Press SPACE (BAR) to display the next selection for a parameter field.
3. Press
~ (CURSOR RIGHT) to select the next field on the right.
4. Press
.... (CURSOR LEFf) to select the next field on the left.
5.
Press. (CURSOR DOWN) to display the next level of fields.
6.
Press. (CURSOR UP) to display the previous level of fields.
7. Press
BREAK to display the default selections for all the parameters of the
currently displayed field level.
8. Press
ENTER to display the selections that were last saved for all the
parameters of the currently displayed field level.
9. Press
SET UP.
SA VE CHANGES FOR POWER-ON? displays.
10. Press Y or N to save changes in the setup, or go to instruction 11 or 12.
A. If you press Y, all changes, including function key definitions for F6
unshifted through F15 unshifted, are saved for the next power-on.
The screen blanks for two
to five seconds.
B.
If you press N, no changes are saved in memory, but the terminal
operates with the current parameter selections.
The next time the terminal
is powered on the setup is the same as it was
before these changes were made.
II. Press SET UP to return to level 1 of the setup parameters.
12. Press
BREAK to set all the parameters to the default setup.

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 brack-
ets (e.g.,
<PO> is the first parameter; Pi signifies any legal parameter value).
Sequence Default Mnemonic Action
ESC )) (space) WYID Reports the Wyse product
number to the host
computer (sends 75 CR).
ESC, WYDELAY Delays processing for
approximately 250
milliseconds.
ESC 5 WYXCH Transmits the character at
the cursor address.
ESC 7 DECSC Saves the cursor position,
attribute, wrap flag,
character sets, and
origin mode status.
ESC 8 DECRC Restores the previously
saved cursor position,
attribute, wrap flag,
character sets, and
origin mode status.
ESC = DECKPAM Turns on the keypad
application mode.
ESC > DECKPNM Turns off the keypad
application mode.
ESC D IND Moves the cursor down
one row, scrolling the
screen up at the last
row.
ESC E NEL Moves the cursor to the far
left column
of the next
row, scrolling the screen
up at the last row.
