INTRODUCTION
Breeze ECT is a standalone terminal used to connect to Railway Application servers through Serial
port or through LAN for performing various activities related to Railways Ticketing applications
This can be used as a Dumb Terminal or Client of a Server based Computing System wherein all
applications and data are deployed, managed and supported on the Server. In addition, the entire
execution of the application takes place on the server. As the application logic is separated from the
user interface i.e., screen updates at the server and transported to the client, the Bandwidth occupied
is very less.
The Breeze ECT is a DEC VT320 Compatible data communication display terminal with many
advanced features. It consists of Three Modules. They are Display unit, Control Unit, and Keyboard
Unit. The Keyboard is Detachable.
This manual is intended for the users of ECT and provides the information needed to install and
operate the ECT. Screenshots have been used wherever possible to improve understanding.

INSTALLATION
This chapter provides instructions to install and turn on ECT. Perform each step in order.
2.1 Box Contents
The ECT comes with the following items. Unpack the carton box and Check to make sure that you
have the following items.
i. ECT (Terminal Unit)
ii. 12V DC Adapter along with power cord
iii. User's Manual CD.
2.2 Do’s and Don’ts
Do’s and don’ts that needs to be taken care while installing the terminal is as follows
Do not place the terminal where it is subjected to a great deal of shock or vibration.
Do not use or place the terminal where there is excessive dust or heat.
Locate the terminal as far as possible from noisy electromechanical devices and avoid
locations that are characterized by strong magnetic fields.
Avoid placing objects on or around the terminal that will restrict the airflow through its
ventilation slots.
Place the terminal on a flat hard surface allowing 5 inches on all sides for ventilation.
Always use a grounded AC power outlet for powering the terminal.
Place the terminal sufficiently near the AC outlet for power connection to avoid any strain
on the AC power cord.
2.3 Connecting the Cables to Terminal
CAUTION: Do not force the connectors into the socket. If any resistance is encountered, ensure
that the connector is oriented correctly to the socket.
Before connecting the cables, ensure that the cables are of the correct lengths. Before applying power
to the terminal ensure the following:
Ensure that the Power ON Switch Located at the Front Side of the terminal is switched
off before connecting the connectors. The LED should not be glowing in the terminal.
Place the keyboard in front of the Monitor and connect the keyboard to PS/2 port on the
back side.
In case of using a RS232 Connector, Connect console cable from LANSTERM to the
Terminal to DB25 connector in the rear side. In case of using DB9 console cable connect
to the DB9 terminal Serial port.
In case of using a network connection, connect a 10/100 Base – T twisted pair network
cable to the network connector.
Depending on the configuration needs, connect a printer to the parallel port
Connect the video signal cable from the monitor to the 15 pin D type female connector at
the rear side of the Terminal. Secure the cable firmly by tightening the screws available
in the video signal cable.
Plug the Power Cord in to a 230V AC Grounded AC Outlet

2.4 Switching On the Terminal
Connect the Power cord to the DC Adapter
Plug the DC adapter Outlet to the socket in the Terminal.
Connect the monitor to the Power source and switch on the monitor.
Press the power on switch provided in the front side of the Terminal to turn on the
terminal. The power on LED indicator located at the front will glow.
When the terminal turns on, boot messages will appear on the screen and all LEDs in

GLOSSARY
..an embedded design lab
37
ASCII : American Standard Code for Information
Interchange
ANSI : American National Standards Institute
Auto print mode : It is a method of printing information directly from
the host system. The terminal sends a display line to
the printer after a carriage return or form feed character.
Character set : This is a group of graphic characters and control
characters stored as a unit in the terminal. Graphic
characters are characters displayed on the screen. Control
characters perform special functions.
Cursor : Cursor is an indicator that highlights the active
position on the screen. The terminal uses different cursor
characters which can be modified in menu.
Display : It is the information that appears on the screen.
Factory default : This is a standard setting for a feature. The terminal
uses factory-default settings, unless you select a new
setting. Many menu features have default settings.
Host system : The computer servers the user connects to the
terminal. If the user connects the terminal to two systems,
one is the primary host and one is the secondary host.
Menu : A set of display screens on the terminal that allows
the user to view and modify the settings of the terminal's
operating features.
Modem : Modulator - demodulator. A device used to convert
data from a computer or terminal into signals that can be
sent over a telephone line.
Modifier key : A key pressed in combination with another key, to
modify the code sent by that key. Ctrl is a modifier key.
National replacement character set : Seven-bit character sets for many European
languages. Each character set with 94 characters. NRC
sets are similar to the ASCII set, except for a few
characters.
Nonvolatile memory : Nonvolatile RAM (Random Access Memory). The
settings are not lost when the terminal is switched off.
Port : The logical route for data in or out of the controller
board on the terminal. Also, another term for connector.
One port can support one or more connectors.
Scrolling : Moving data between the margins of the page
currently displayed. Data scrolled past the margins is lost
from page memory, but usually not from the host system.

Scrolling region : The area on the current page i.e. between the top,
bottom, left, and right page margins. The default scrolling
region is the complete page. Only a programmer can
change the page margins.
Session : An active connection between the terminal and
a host system. When user log-in to a computer from the
terminal a session is opened.
Status line : A display line that provides information about the
session's current operating state. The status line appears
at the bottom of the screen.
Terminal server : An intelligent unit that can connect a number of
asynchronous devices (terminals and printers) to a host
system.
Visual character attribute : A quality of a display character that highlights the
character, such as bold or underline.
Window : A specified area of the screen used to display
information from page memory. User can divide the screen
horizontally into two windows, to display information from
two sessions at the same time.
