</span>How confident are we in the ground at each end of the run? Is the<br>
existing cabling shielded and grounded at both ends? If we're going to<br>
ground both ends of the run, let's make sure we're not making a<br>
significant ground loop.<br>
<br>
I don't know nearly enough about the electrical service at Omni to have<br>
an opinion on whether a ground loop is likely, and I'm definitely not a<br>
pro at this kind of thing, but I think if you stop just short of<br>
hooking it up and measure the current through the drain wire, as long<br>
as it's reasonably low you're in good shape.<br>
<br>
I don't do a lot with shielded twisted pair though, so if I'm confused,<br>
please correct me. :)<br></blockquote><div><br></div></span><div>No you're right. We need to ensure we're not doing something stupid here and I don't know anything about the grounding at Omni. If someone else runs the cable and leaves the ground wire dangling then I'll take care of grounding (or not) as needed.<span><font color="#888888"><br><br>-- <br></font></span></div><span><font color="#888888"><div>marc/juul<br></div></font></span></div></div></div>
