I was looking at my Extron catalog and they offer a cable that is called a STP20-2P. It's basically two twisted pairs, 20 AWG, with each pair wrapped in a foil shield and with each pair having a drain wire. Can I use this Extron cable? Would the twisting of the pairs present a problem? Please let me know.
The Extron cable should be OK. Twisting of the pairs is desired.
