----------- TRS-SO ® -----------
Introduction
What is a data terminal?
Terminus: Lat. Boundary or End.
A
data terminal is the connection hetween you and a
computer. It is not a corrputer. It is a connection to a
computer
and transfers information fran hurran form (e. 9•,
letters, nU1lt>ers, etc.) to a forrrat corrputers understand
(e.g., electrical pulses).
There are three Parts to a Terminal:
The Keyboard, where you enter data.
The Video SCreen, where the Computer outputs data in
visible form.
The
Input/Output Channels, where the Terminal
communicates wi th the Computer.
Vhen you connect a Data Terminal to a power source and turn
the switch ON, nothing really happens unless the Terminal is
connected to a"Host" corrputer. A Host is the controlling
computer in a rnultiple-computer system. Consequently, the
cperation and caPabilities of your Data Terminal are limited
onl y by the li mi tations of the Host corrputer -- your
Terminal can only do what the Host can do and no rrore!
For instance, your Data Terminal cannot store programs or
data itself, but it can access inforrration stored by the
Host System.
tbte that different Host Systems operate in different ways.
In fact, they may even recognize different keyboards. If you
press a key on the Terminal when it is connected to one
Host, the reaction rray he totally different than when you
press the sarre Terminal key when it is connected to a
different Host!
In other words, the specifie q;>eration of your Data
Terminal depems upon the Host that is in control.
Consequently, good Data TerminaIs (like the DT-I) must he
designed to oPerate with a variety of different Hosts.

Where is the Host cœputer?
ONner'sManual
The
Host corrputer rray he located near the IJI'-l (directly
connected), or it rray he hundreds of miles away and
connected to your Terminal via rrodems and telephone Unes.
can aDT-I cœm.mi.cate with another or-l?
Yes, t\\U DT-l' s can cormumicate (e. g., you and another IJI'-l
user can "talk" by typing on the keyboard) but that 1 salI
they can do. They can 1t process or store any inforrration
unless they 1 re connected to a Host.
other special fea.tures of the or-l include:
A 7~-key console keyboard that includes a 12-key
nurœric pad and conforms to standard Data Terminal
keyroard forrrat.
A 12-inch SCreen to display inforrration.
Both serial and Parallel Printer Interface for
hard-copy output of data (requires a seParate printer,
optional/ex:tra) .
RS-232-e
Interface for quick and efficient inforrration
transmission hetween the Data Terminal and the Host
System.
Software selectable "switches" to establish
Input/OUtput Pararœters, such as Reverse Video, Baud
Rate, Autorratic Line Feed, and nnre.

1/ Description of the DT-l
Before you begin using the DT-l, it's important that you
become familiar with it. This section will describe the
Terminal, particularly sorne of the keys which you may not be
familiar with. Remember though, the description of a
particular key (e.g., what it does) may differ from Host to
Host.

Figure 1. The DT-l Keyboard Console
There are two parts of the DT-l keyboard. On the left is
the standard, typewriter-style keyboard with a few
additional keys. On the right is a standard l2-key numeric
pad that also has special functions.
To right of the numeric pad is the red, "power-on light."
Whenever the DT-l is on, this light will illuminate.
Around the edges of the standard typewriter keys are sorne
keys that most typewriters do not have.
