                                                      MA-0811-90.DG




System Box
The system box contains the terminal’s logic and memory boards. It also
provides the connectors for power, system communication, and other
devices. A cover panel attaches to the rear of the system box to conceal
the connectors and cables. The system box is 368 mm deep 394 mm
wide 57 mm high (14.5 inches 15.5 inches 2.25 inches).

Monitor
The terminal comes with one of the following monochrome monitors:
    VR315 (380 mm/15 inch) with tilt-swivel stand
    VR319 (480 mm/19 inch) with tilt-swivel stand
    VRE01 (480 mm/19 inch) flat panel display
When connected to a host system, the monitor displays information you
send to the host system and information the host system sends to you.
For more information about your monitor, see your monitor’s installation
guide.

Keyboard
The keyboard has four groups of keys and two indicator lights. The
keyboard cable connects to the system box. Chapter 8 describes the
keyboard.

Mouse
The mouse is a three-button pointing device. You use the mouse to make
selections from screen menus, enter data for graphics, or select points on
the screen. The mouse connects to the system box. Chapter 4 describes
how to use the mouse.

X Window Sessions and Video Terminal Sessions
You can use two types of sessions on your host computers:
   X Window Session
   To use an X window session, you log in to a host and use that host’s
   X window software. In an X window session, you can use all the
   applications and utilities provided in the X Window System. For more
   information about Digital’s X applications, see the VMS or ULTRIX
   version of the DECwindows User’s Guide.
   Video Terminal Session
   You can use your VT1200 as a video text terminal. The VT1200
   has a video terminal (VTE) window that lets you log in to a host
   as you would on a conventional video terminal. The VTE window
   offers most of the features of Digital’s VT320 text terminal with some
   enhancements.
You can open one X window session and several VTE sessions at the same
time.

X Window System and DECwindows
The X Window System is a graphically oriented user interface that
lets you display one or more windows on the screen. Each window can
represent a different software application running on its own host system.
For example, you could run a word processing application in one window
and a spreadsheet application in another window. With windows, you can
perform many tasks in an easy and efficient manner.
The X Window System was designed at the Massachusetts Institute
of Technology. Digital’s DECwindows software is based on and fully
compatible with the X Window System.


                                                                  Chapter 1
4 A Look at the Terminal



System Requirements
You can use your terminal with the VMS, ULTRIX, and UNIX based
systems.

VMS Systems: LAT Protocol
The VMS operating system is one of Digital’s operating systems. To make
network connections to a VMS host system, use the local area transport
(LAT) protocol. LAT is a communications protocol for connecting to VMS
host systems.
To open a video terminal (VTE) session:   You can use any version of the
VMS operating system.
To open an X window session: You must have VMS Version 5.3-1 or higher
installed on your system, and your system manager must enable certain
options (Appendix D).

UNIX and ULTRIX Systems: TCP/IP TELNET Protocol
The UNIX operating system was created by AT&T and is used throughout
the computer industry. The ULTRIX operating system created by Digitial
is based on the UNIX operating system. To make network connections
to a UNIX or ULTRIX host, you normally use the transmission control
program/Internet protocol (TCP/IP) networking software. TCP/IP is the
preferred communication protocol for UNIX-based systems.
The VT1200 uses the TCP/IP TELNET protocol to make network
connections to UNIX-based host systems. TELNET is the TCP/IP protocol
that lets terminals connect to host systems in a wide-area network.
To open a video terminal session:   You can use any version of UNIX or
ULTRIX.
To open an X window session:   You can use any version of UNIX to open
an X window session, as long as any X11R3 client is installed on that
host. ULTRIX workstation (UWS) versions 2.1 and higher include an
X11R3 client.

How the Terminal Works
You can use the VT1200 with one or more computer systems. You have
several options for connecting your terminal to a computer. You can
connect the terminal directly to a computer through one of two serial
ports, or you can connect the terminal indirectly through an Ethernet
network using the ThinWire port.
The computer system you connect to is called the host. You can connect
several VT1200 terminals to a single host or connect one VT1200 terminal
to several hosts.
You use the keyboard and mouse to interact with applications on your
system. You send data to the application by typing on the keyboard or
selecting window options with the mouse. Data sent by the application
appears as text or graphics on the screen. You can print text or graphics
from the terminal.

6 A Look at the Terminal



You can use a variety of host software applications on the terminal. For
example, your host may have applications for word processing, data entry,
programming, or business graphics. Most applications involve interactive
processing. This means the terminal immediately sends the information
you enter from the mouse or keyboard to the host.
Applications use programming functions to perform many operations. The
terminal can work with standard American National Standards Institute
(ANSI) functions. See Chapter 10.

features. You can
•   Change individual feature settings.
•   Recall factory-default settings or your own stored settings from
    memory.
•   Make temporary changes for the current session or store new settings
    for all future sessions.
Chapter 7 describes how to customize your terminal settings.

Compatibility with VT Series Terminals
The VT1200 can operate as a video text terminal when you want to log
in to a host system as you would with a conventional video terminal. You
can use the terminal as one of Digital’s VT320, VT220, VT102, VT101,
or VT100 text terminals. Chapter 5 describes the video terminal (VTE)
window and how to use it.

Character Sets
When you use video terminal (VTE) windows, you can choose different
character sets to match your computer system or software application
requirements. You can choose from:
•   Two 8-bit multinational character sets—DEC Multinational or the
    the ISO Latin Alphabet No. 1 set of the International Standards
    Organization
•   Several 7-bit national replacement character sets (NRCs) for Western
    European languages
Chapter 5 describes how to choose characters sets.

Programming the Terminal
The VT1200 video terminal (VTE) windows emulate Digital’s VT320 text
terminal. The VT320 Programmer Reference Manual explains the control
functions used to access the terminal’s video terminal (VTE) window
features. Chapter 10 of this user guide is a summary of VT1200 specific
control functions and commands. Programmers use these functions in
their applications.

to a host computer system:

ThinWire       Lets the terminal operate with X window applications and
connector      multiple text terminal sessions, using either the LAT or TCP/IP
               network protocol. You must use the ThinWire connector to operate
               with X window or DECwindows software.
Serial         Lets the terminal connect to a single host or terminal server as a
line           traditional text terminal.

Selecting a Location
Use the following guidelines to select a good location for your terminal:
•   Select a surface area that is large enough to hold your system box,
    monitor, keyboard, and mouse.
•   Select a location near ac power outlets and communication connectors.
•   Keep your terminal away from heaters, photocopiers, direct sunlight,
    and abrasive particles.
•   Do not block the air vents on the sides of the system box or place the
    system box on its side. Blocking the air vents can cause the system to
    overheat.
•   To avoid screen glare, select a place where bright light will not reflect
    off the monitor.
•   Place your monitor so that the top line of the monitor display is at eye
    level.
•   Keep the air well circulated, to prevent excess heat and dust from
    accumulating.
•   Keep the temperature between 10° and 40° C (50° and 104° F), and
    the relative humidity between 10% and 95%.
•   Keep the area clean. Do not place food or liquid on or near your
    terminal.

                                              Getting Started


This chapter provides step-by-step procedures on how to begin using your
terminal with a host computer. The chapter also introduces some of the
terminal’s screens and menus.
If you are unfamiliar with using windows and a mouse, you may want to
read the information in Chapter 4 before continuing.
Before you start, you should set the terminal to use the desired display
language and keyboard type. By default, the terminal uses the English
language and the North American keyboard type.
You can use your terminal with the VMS, ULTRIX, or UNIX operating
systems. You can open two types of sessions on these systems—a video
terminal session or X window session.
The chapter includes sections on:
•   Terminal Manager window
•   Choosing the correct display language
•   Choosing the correct keyboard type
•   Opening a session on a VMS host system
•   Opening a session on a UNIX or ULTRIX host system
•   Ending a session
