Anyone have references to Twisted pair cable/ Shielded twisted pair? I am looking for general guide lines as to when twisted pairs should be used, and how shields should be used. I have used RS-485 shielded twisted pairs just dont understand why one end of the shield is grounded but not the other end. I suspect it is to prevent ground loops, but I see in other applications where the shield is tied at both ends.
