TomHoward Posted February 22, 2018 Share Posted February 22, 2018 I've got a job where I'm trying to find a rogue Cat5, there's five ends at a projector, four of them on stage but one unaccounted for which I'm hoping goes back to a rack.I've got one of those tone tracers, a piece of BT equipment I think - but the environment is pretty noisy so it's quite hard to hear what's going on. I've tried shorting the ends and metering out on the rack to find continuity but no luck there either... Is there anything more up to date available now for this kind of job? That could give any kind of help? Link to comment Share on other sites More sharing options...

If the cat 5 is connected to a switch, some testers will flash the switch port light which might help find it. Link to comment Share on other sites More sharing options...
TomHoward Posted February 22, 2018 Author Share Posted February 22, 2018 I don't think it's patched - there's an unterminated CAT5 at the projector, which might go back to a rack and be terminated or not.Weird thing is if I stick the tone on it, I get a really strong signal from another line, but not the right one as that meters out both ends as it's labelled. Waiting to hear back from the installer in case they remember anything weird - the building's less than a year old, just the install's a mess.

bruce Posted February 22, 2018 Share Posted February 22, 2018 Tone and probe probably the best bet - and ladders! A proper CAT5 tester would also give cable length, which might give a clue. Link to comment Share on other sites More sharing options...
themadhippy Posted February 22, 2018 Share Posted February 22, 2018 125A 3phase ceeform to ethercon adapter is all you need,plug it in,turn it on with a long stick and listen for the bang,it may also give a visual indication via smoke signals.

abbotsmike Posted February 22, 2018 Share Posted February 22, 2018 I use a fluke intellitone pro 200. Works well, more "clever" than a standard tone and probe as it is very good at locating a cable within an area, then a specific cable in a bundle. Also quite loud and has blinky signal level lights on the probe. Link to comment Share on other sites More sharing options...
lonemorf Posted February 23, 2018 Share Posted February 23, 2018 I have one of these - very helpful in this scenario, but mega mega bucks - luckily a company purchase for me :)https://www.idealnetworks.net/uk/en/products/cable-testing/copper-testing/cable-certifiers-lantek-iii-series.aspx?utm_source=GoogleAdwords&utm_medium=PPC&utm_campaign=Data_Cable_LanTEK_III_UK&utm_term=cat5%20tester&gclid=EAIaIQobChMIh-bb0Iy82QIVS7obCh3m6g_UEAAYAyAAEgLlevD_BwE Link to comment Share on other sites More sharing options...
Martin Posted February 28, 2018 Share Posted February 28, 2018 The Fluke Intellitone stuff is much better at finding signals in noisy environments than the traditional analogue toners. Link to comment Share on other sites More sharing options...
