Installing
the
Terminal
In
this chapter you'll learn
how
to connect the terminal to a computer (or
modem) and to a
serial printer.
Unpack
and
inspect your terminal
and
report anything that's missing or visibly
damaged to your local salesperson.
You
should have a terminal, a keyboard
with
coiled cable,
and
a power cord.
You'll need a 25-pin male
RS-232C
cable to connect the terminal to your
computer or modem,
and
another cable if you plan to connect a printer
directly to your terminal. If the connector cables supplied
with
your devices
do not match the
pin
assignments
in
Appendix B
(or
if you don't have
cables). see your local salesperson. You'll need to plug the terminal into a grounded power outlet. Make sure
your building's
voltage
(115
in
the
U.S.)
matches the voltage shown
on
the
back of your
terminal. If it doesn't, contact your local salesperson.
Allow three inches around the terminal for ventilation.
Follow these steps to connect the terminal to your computer
and
printer:
1.
Press the front half of the power switch
on
the right side of the
terminal to turn the terminal off.
Chapter 1
2
Turning
on
the
Terminal
2.
Plug
the keyboard cable into the terminal's keyboard socket
on
the left
side
and
into the keyboard.
3.
Connect your computer interface cable to the terminal MODEM port
and
to the computer
RS-232C
port. If you're connecting a modem,
follow the modem manual instructions to connect it to your telephone.
Power
Connector
4.
If you have a serial printer, connect the printer interface cable
to
the
terminal AUX port
and
to the printer RS-232C port.
5.
Tighten the screws
on
both sides of each connector with a
Va-inch
flat-blade screwdriver to secure the connection.
6.
Plug
the slotted (female) end of the power cord into the three-pronged
connector
on
the back of the terminal. Plug the pronged end into a
grounded power
outlet (three-slot
in
the U.S.). If there's
no
grounded
outlet nearby, you
can
use
an
adapter if you ground the outlet by
attaching the adapter
pigtail to the outlet faceplate screw.
After the
terminal is properly installed, turn it
on
by pressing the back half of the
power switch
on
the right side of the terminal. Listen for a beep indicating
that the
terminal has received power.
When you turn the
terminal
on,
it tests itself for a
few
seconds. If it's been
on
recently, the screen flashes several display patterns
as
the test runs. If
testing uncovers a problem, a beep sounds,
an
error
code-A,
C,
K,
P,
X, Y,
0,
or
9-appears
in
the bottom right corner of the screen,
and
you can't
operate the
terminal.
See
Chapter
4,
"Troubleshooting.
If
Installing the Terminal
Making
Comfort
Adjustments
When you see the cursor
in
the upper left corner of the screen, the terminal
has
passed
all
of its tests
and
is
ready for operation. Generally, the next
thing to appear
on
the screen
is
the status line. This line
is
a bold rule at the
top of the screen
with
the letters
FDX,
BLK,
or
HDX
on
the upper left side.
Adjust the
terminal so the center of the screen
is
slightly below your eye level.
Tilt
it to find the
most
comfortable angle. Adjust the screen's brightness
with
the slideswitch
at
the lower right corner. The slide switch markings are
for your convenience. Brightness
levels may vary from terminal to terminal.

Setting
U p
the
Terminal
In
this chapter, you'll learn
how
to enter setup mode
(a
nonoperating mode)
to adapt your
terminal to your computer, peripherals, and application
programs. The terminal cannot communicate
with
a computer or printer
unless they communicate
in
a common language.
In
the first six levels of setup mode, you choose parameters such
as
baud
rate and
compatibility,
as
required by your computer, peripherals, and
application programs.
You
choose other parameters, like cursor style and
carriage return, to suit your
particular needs.
In
the seventh level of setup mode, you
can
program the terminal control
keys,
as
well
as
the accounting keys
and
function keys. Thus, you can enter
frequently repeated key combinations, or even long character strings,
with
a
single keystroke.
Default values for each parameter are set
at
the factory and you can always
return
to
them. Values you save
in
memory when you leave setup mode
remain
in
memory until you change them. Values you
don't
save remain
in
effect only until you turn
off
the terminal.
Several
other terminal features
can
be turned
on
from the keyboard (see
Chapter
3).
The terminal's default values may not match the requirements of your computer, modem, or printer. Look
in
their manuals
and
note the
requirements
in
the inside back cover of this manual for future reference.
~
Caution-Don't enter setup mode while data
is
being transmitted between the
terminal
and
the computer. The terminal cannot receive data during setup
mode. To
enter setup mode, press the SHIFT
and
SETUP
keys simultaneously.
Any information
on
the screen remains frozen until you exit setup mode,
and a
line of boxes, called fields, appears at the top of the screen. These
fields prompt you
in
setting
up
your terminal.

the top
row
of
the
keyboard. Although 16 function keys are labeled
as
such, you effectively have 32. All
16 function keys can be shifted giving you a total
of
32 function keys.

Full-Duplex
Mode
Full
duplex
is
the default mode.
In
this mode, the terminal sends keyboard entries only to the computer. The computer may send data back to the terminal, where it's displayed
on
the screen. While the terminal
is
in
full-duplex mode, FDX appears
on
the status line.

In
half-duplex mode, data goes to the computer
and
the terminal at the
same time. While the terminal
is
in
half-duplex mode, HDX appears
on
the
status line.
Controlling the Terminal
Block
Mode
In
block mode, keyboard entries go only to the terminal's screen. When a
block
of
text
is
ready, you
can
send it to the computer
with
the SEND
key.
Data from the computer
is
also displayed on the screen. While the terminal
is
in
block mode,
BLK
appears
on
the status line.
Half-Duplex
Block
Mode
Half-duplex block mode
is
the same
as
block mode except the terminal
follows
Request-To-Send
(RTS)
and
Clear-To-Send
(CTS)
handshaking
protocol. While the terminal
is
in
half-duplex block mode,
BLK
appears
on
the status line.
Monitor
Mode
In
monitor
mode, the terminal displays
all
characters, including control
characters, but does not act
on
them. This
is
useful for debugging
programs.

Symptoms
and
Solutions
4
Troubleshooting
Often a suspected terminal malfunction
is
something you
can
easily fix.
Read
this chapter before placing a service call. The symptoms are shown
in
bold type, followed by suggested solutions .
•
Warning-We
are NOT suggesting that you try to fix internal terminal
problems.
DO
NOT open the terminal case unless you are a qualified service
technician.
While the case
is
open, dangerous voltages are exposed (even
after the
power
has been turned off).
Terminal doesn't maintain its tilt angle
with
all cables attached .
•
Warning-Do
not disassemble the terminal's foot mechanism because it's
spring-loaded under extremely high tension. Adjust the foot spring
with
a flat-blade screwdriver, not more than
one-quarter turn at a time.
If the foot does not extend when
the
terminal
is
tilted forward, turn the screw counterclockwise to loosen it.
Power switch
is
on, but display
is
blank.
If the foot stays extended so the terminal is too upright, turn the screw clockwise to tighten it.
Turn the
power
switch
off
and
on.
Did
the terminal beep? If not, make sure
the
power
cord
is
connected both at the terminal and at the electrical outlet.
Troubleshooting
Terminal beeps but you can't see cursor.
Adjust the brightness
slideswitch, sliding it to the far right.
Screen goes
blank while
the
terminal
is
on.
This
is
a normal condition if the screen saver parameter
(CRT
SAVER)
is
on,
and the terminal
is
inactive for
18
minutes. Press the SHIFT key to bring
back the
display without changing the data.
Display doesn't respond when you press a
key.
If
LOCK
appears
in
the status line, the keyboard
is
locked. Press the
SETUP
key. Press the
CAPS
LOCK key several times. If
CAPS
does not appear, make
sure the keyboard
is
properly attached
and
functioning. If
CAPS
appears, the
keyboard
is
working, but not communicating
with
the computer.
Go
into
setup mode
and
make sure the setup parameters match your computer.
(See
the next condition.)
The computer doesn't respond when you type
on
the keyboard.
Make sure the computer
and
keyboard cable connections
are
correct.
See
Chapter
1.
Check your setup parameters. Select
FOX
mode
and
make sure the
handshake, baud rate, data bit, stop bit,
and
parity bit parameter values
match your computer's requirements.
When
the
terminal
is
turned on, error codes A,
C,
K,
X, or Y appear
at
the
lower
right side of
the
screen.
Press the
SHIFT
and
SETUP
keys simultaneously to stop the manufacturing
self-test. If the error code continues, simultaneously press SHIFT
and
SETUP
twice more,
and
press Y to restore the factory default values.
