not
the default configuration you need to run set
up
(Chapter 2) before printing.
Review
the entire installation procedure before
you
start.
Make
sure you have the necessarycables
and
have
preparedasuitable location, as instructed
in the previous sections.
~
WARNING
II
Neveropen the terminalcase. You can
receive aserious electrical shock,
even when the terminal
is
off and un-
plugged. Always call atechnician to
service the interior of the terminal.
This
chapter
containsinstructionsfor installing the
terminal. Following this is asection
on
connecting
the
COMI
(or
COM2)
serial port to ahost com-
puter, the
COM2
(orCOMl)
serial portto asecond
host
or
serial printer, and the parallel port to a
parallel printer.
Preparation
Before
you
start the installation process, plan
your
system
layout:
•Prepare the site.
•Decide
on
acomputer interface type and
obtain all cables.
Choosing aSite
•Choose alocation with indirect lightingfrom
windows or other sources of indirect light.
•Allow about 4inches (10 em) of clearance
for ventilation
on
all sides.
•Place the keyboard lower than the screen.
•Select furniture conducive to good working
posture.
Interface Types and Cables
The type of interface you select depends
on the distance between the host
and
the
terminal.
If
the distance between the terminal and your
computer
or
modem
is less than
50
feet, connect
them
with an interface cable that mates with the
serial ports
on
the terminal.
Cables for connecting the terminal to acomputer,
modem,
or
printerare not included with the termi-
nal.
The
service technician in
your
organization
should
be
able to obtain the cables,
or
you can
contact a
computer
supply dealer.
Installation
USER'S GUIDE
1-1
INSTALLATION
.1
IHost Connections
Make sure you have the appropriate interface, as
discussed at the beginning
of
this chapter.
For
an
RS-232C interface, connect the cable between the
COMI
port and the RS-232C port
on
the host
or
modem.
The
COM2
port has a9-pin connector.
If
you have to rewire the cable for proper communi-
cation with the computer, see the pin assignments
for
COMI
and
COM2
ports
on
the fol1owing
pages.
Port Pin Assignments
The terminal has two serial communication ports
and aparallel printer port.
Serial Ports
Determine the signalsthateach unitrequires. Typi-
cally, the tenninal requires only Transmit Data,
Receive Data, and Ground for serial communica-
tion. Some computers, however, may require ad-
ditional signals. Find out
if
the serial port for each
interface isdatacommunication equipment(DCE)
or
data tenninal equipment (DTE) type. Checkthe
hostcomputerand printermanuals for dataon port
type, required signals, and signal direction.
NOTE: Before buying any cables, check pin
assignments in Table 1-1, Table 1-2, and
for the connector on the host computer.
Make sure the connectors at each end mate
(male to female) properly.
COM1 Serial Port
The
COMI
port has afemale 25-pin D-connector;
your computer
or
printer may not have a25-pin
connector (some units have a9-pin connector)
or
the DCFJDTEinterfacesmay notmatch up. In such
cases, consult atechnician
or
yourdealerfor assis-
tance. When connecting the
COMI
port to ahost
computer, refer to its manual and Table 1-1.

Since the terminal has the capability to toggle
(Host 1or Host 2) between two host computers,
use the COM2 port to connect to the second host.
NOTE: Before buying anycables, check pin
assignments for
COM1
and COM2 (Tables
1-1
and 1-2) and for the connector
on
the
device. Make sure the connectors at each
end mate (male to female) properly.
Checkthe portconnector
on
the secondhost. Make
sure the cable you use has connectors (9-pin
or
25-pin) that mate with connectors
on
the terminal
and host computer.
If
you connect the
COM2
port to aserial printer,
use acable with afemale 9-pin D-connector; the
other
end
must mate with the printer connector.
When connecting the
COM2
portto acomputer
or
other serial device, refer to Table 1-2, and to the
manual supplied with the computer
or
device.

PARALLEL Port
TIle parallel port has a25-pin D-connector, with
Centronic-compatible signal levels. At aprint
command, the STROBE signal gates the first byte
of
dataout on data lines DO-D7 to the printer. The
printer responds with acknowledge signal ACK,
and the process repeats until the last byte is sentto
the printer. TIle presence
of
any other input signal
from the printer (BUSY, PE, or ERR) will inhibit
all data lines to the printer. Pin assignments are
shown in Table 1-3.
Plugging In the Terminal
Do not push in the power switch before plugging
in the terminal. Plug the power cable into the
terminal first, then plug the cable into agrounded
wall outlet.
NOTE:
In
the United States, use athree-
prong electrical outlet with aNational Elec-
trical Manufacturer's Association (NEMA)
Standard 5-15R rating. If you use atwo-
prong adapter, make sure it is properly
grounded.
Turning On the Power
To
turn on the power, press the right side
of
the
green rocker switch on the front
of
the terminal;
make sure the switch is illuminated.
After 10 to
15
seconds, acursor appears. (The
default cursor is ablinking block.) There may be
astatus line above the cursor, and you may see a
login message
if
the terminal isconnected to ahost
computer.

INSTALLATION
The terminal
is
ready to operate when you turn it
on, but you need to checkthat its parameters agree
with your host, your printer and otherperipherals,
and yourapplication programs.
There are three basic types
of
set-up parameters:
•Communication values that must match
those of other system components. (For
example, terminal and host must communi-
cate at the same data rate.)
•Operating values that must agree with your
application program. (Does your spread
sheet require 80 or 132characters per line?
What terminal emulation mode does your
program require?)
•Personal preference values. (silent or click-
ing keys? darkorlightscreen background?)
When in doubt about aparticularparameter, don't
change it. Default (factolY set) values are those
commonly employed in system communication
and data enti)'/processing.
Application programsoftenreset terminalparame-
ters for you automatically. Refer to yourcomputer
and application program manuals first,
or
consult
your system manager, for specific information
about your system.
Parameter Menus
This chapter presents the set-up menus. Their
names are displayed nearthe top
