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.
