User Datagram Packets
Connectionless Protocol◦email instead of phone call
No error checking◦Faster data transmission◦Less bandwidth needed
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
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.
Implementation Design
SHOTS TELESCOPE
SYSTEM
Video Control Switch
Serial Device Servers
Outputs Network
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
Sent out: “**Y<output#>,<input#>!!” Receives:
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)

Inputs/Outputs Network
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.
