RJ45 UTP/STP cable tester

Hello,

I've built a simple RJ45 UTP/STP cable tester.
You can find the schematic of the emitter and the receiver on my site: **broken link removed**

Happy new year!

Huh! That's actually a great super simple way to check the cable is not broken anywhere. Happy late New Year and thanks for the link.

Edit: Does it pulse across the wire at a frequency or just a dc voltage?

Hello,
Just a DC pulse across the wire, from the counter output.
