Introduct ion
USING THIS MABUAL
Chapter 1 contains step-by-step instructions showinq how to
install the terminal.
Selecting the terminal's operating characteristics and
configuring it to communicate with your computer and printer
are covered in Chapter 2.
Chapter 3 describes the keys and terminal operations
controlled from the keyboard.
Chapter 4 has a troubleshooting table and tells how to get
assistance if you have questions or problems.
Chapter 5 is for programmers and operators who want to control
the terminal through programming commands. It explains the
commands and the terminal operations they control.
At the baCK of the manual is reference material: appendices,
glossary, index, and a programmer's quiCK reference guide.
Attention, Please
This manual has three types of notices you should read
carefully:
NOTE: Information of special interest or importance about a
feature.
WARNINGl Potential loss of data or damaqe to the terminal.
STOP I Possible harm to the user.
xii

1. INSTALLATION
Thi s chapter te 11 s you how to ins ta 11 the 9220. A summary of
installation steps is at the end of the chapter.
UliPACKING
Unpack the terminal carefully. Keep the shipping carton and
packing material in case you move or ship the terminal.
The packing carton should contain (besides this manual):
Terminal
Keyboard
Two keyboard legend labels
Coiled keyboard cable
Power cable
Inspecting the Terminal
STOPl Do not open the case to inspect the interior unless you
are a qualified technician. Opening the case exposes you to
potential shock hazards.
Inspect all the parts for shipping damage. If anything is
missing or damaged, call your distributor or dealer.
If the screen is broken, protect yourself by using tongs and
gloves to handle the broken fragments. The fragments are
sharp and the coating on the inside of the tube is poisonous.
Selecting a Site
Choose a site with indirect lighting, away from windows and
other sources of bright lights and glare, to avoid eyestrain.
Figure 1-1 shows comtortable terminal lighting.
MaKe sure the terminal has adequate ventilation. Allow at
least 4 inches (10.2 cm) for ventilation on all sides.
Select furniture conducive to good working posture and place
the terminal at the correct height. The keyboard should be
lower than the screen.

Installation
HO~E: You need not worry about X-ray emissions. Tests
performed on TeleVideo terminals by Underwriters Laboratories
indicate they emit virtually no radiation and pose no health
hazard.
Figure 1-2 shows the ideal relationship between the terminal
and the operator.

Installation
COnnectinq the ~eyboard
Insert the preprinted leqend label into the bezel directly
above the row of function keys. Save the other blank label.
Pluq the ends of the coi led keyboard cable into the back of
the keyboard case and the front of the terminal (Fiqure 1-3).
Before You Connect the ~er.inal
Make sure the terminal voltaqe settinq matches your electrical
outlet. The terminal should carry a label st~tinq whether its
settinq is 115 volts or 230 volts ac power. Call the
~eleVideo Customer Service Department for instructions if you
want to chanqe the voltaqe settinq.
If you need a neutral fuse to meet international standards.
ask your dealer or service technician to install it for you.
Measure the distance between the terminal and your computer or
modem. If it is less than SO feet, you can connect the two
with an RS-232C interface cable (with a 25-pin connector).
If yo~r CCL:puter is mo!'e than SO feet away, use a 20 mA
current loop interface with an eiqht-pin connector.
COnnectinq the ~er.inal With an RS-232C Interface
If you use an RS-232C interface, follow these steps:
1. Compare the suqqested connector pin assiqnments, listed
in Table 1-1, with you!' computer's. (Figure 1-5 shows
the terminal pin numbers.) If necessary, ask your
service technician to chanqe the interface cable pin
af:siqnments.
BO~E: Not all computer connector pins are compatible
with standard RS-232C pin assiqnments. See Table 1-1 for
required siqnals. If your terminal does not operate
properly, check your computer manual or company service
department for assistance in wirinq the interface cable.
2. Connect the ·interface cable to the terminal port labeled
RS-232 COMPUTER and the computer RS-232C port.

Connecting the Terminal With a Current Loop Interface
The 9220 or your computer can supply the 20 mA power source to
drive a current loop signal. Table 1-2 shows the-9220 current
loop connector pin assignments, and Appendix H shows terminal-
host interface wiring for various power source configurations.
To connect the terminal with a current loop interface:
1. ~SK your service technician to correctly wire the
interface between the terminal and host. (Figure 1-6
shows the eight-pin 20 mA connector numbers.)
2. Connect the interface cable to the eight-pin current loop
connector (see Figure 1-4) and the host current loop
connector.

1. As you did with your computer, check your printer
connector against the terminal printer port pin
assignments, shown in Table 1-3.
2. Connect an RS-232C interface cable with a 2S-pin
connector to the 25-pin port at the back of the terminal
labeled PRINTER. See Figure 1-4 for the location of the
printer port.
NOTE: Not all printer connectors are compatible with
standard RS-232C pin assignments. See Table 1-3 for
required signals. If your printer does not operate
properly, check the manual or company service department
for assistance in wiring the interface cable.
