G – Graphical
U –User
I - Interface
An interface that allows the user to
interact with the computer using a
mouse.
 Tool
Command Language
◦ Easy string based scripting language
 Toolkit
◦ Used with TCL to create the Graphical
part of the user interface.
 Platform
independent.
◦ Build in Unix used in Windows
Implementation Design
 Build the GUI to given specifications.
 Connect all the devices together correctly
and test each component.
 Use the serial device server to reach video
control switch.
 Send commands to the video control switch
over network using UDP and confirm
results.

Design Specifics:
◦ One input may have many outputs (Not vice
versa).
◦ Load in configuration and labels files
◦ Save current configuration to a file.
◦ Communicate with a Serial Device Server over
Ethernet.
◦ Display the current configuration in real time.
◦ Simplicity

Unfamiliar with TCL/TK language in Linux
environment.
◦ Normally used csh in windows

Networking
◦ Incorporating a networking feature into a program
◦ Working with UDP


Hardware Problems
◦ Faulty cables
◦ Serial Device Servers
 Can only be fully configured using Internet Explorer (IE).
 Configurations have a tendency to change.
 Reboot about every 6 hours. (Loss of Connection)

Was able to successfully communicate with the
server and switch.
Create the GUI with a few add-ons but still
meets the specifications.
Documentation for testing and setting up the
devices.
Serial Device Servers changed over to static IP.
