PC control over Cat5

Post by fancontrol » Tue Sep 28, 2004 12:11 pm

Remember this? Well, I just can't let it die.

Today I found an article from intersil about how to use their parts to send video over cat5. It looks like I can sample most of the parts, so I'm thinking I might be able to build one (or three) of these things.

The trick is keyboard and mouse. The video only uses 3 of the 4 UTPs, any thoughts on how to squeeze mouse & kbd onto the remaining pair?

Anyone know of a sparky kinda forum that might be able to help?
Anyone willing to part with some cash to take part in the effort? I ask primarially because the board shop, ExpressPCB, makes 3 sets of boards minimum for $65 total. Spreading the pain would be nice.

If I had $65 right now I'd bet all of it that this project goes nowhere. I'm too freakin' busy these days...

Use a dual-PS2 to USB converter like this and send the data and clock signals through the cat5? Then the +5v and gnd could be hooked up at the workstation with a power brick or something.

Check www.avsforum.com
Search the front projectors forum, there are a couple threads on a nice adapter that lets you do nice in wall VGA to Cat5e installs.

As for Mouse and Keyboard, there are a few KVM's that have a Cat5 extension. Belkin has one. Also, you could use Cat5e USB extenders, but it would probably be cheaper to just buy the KVM switch.

The mouse and the keyboard are feed with 5V and GND, then each of them has a Clock and a Data signal.

1. Data Mouse
2. Data Keyboard
3. Clock Mouse
4. Data Keyboard
5. VCC = 5V shared Keyboard - Mouse
6. VDD = GND shared Keyboard - Mouse

Get a cable with more wires inside. ;)
