I heard that too, but the engineer in me would really challenge that. Anyways, pulled almost all of the cable out - same problem. Shortened the cable (120 feet shorter) and left it all on the spool, NO problem. This is also a sample size of two as far as the fix goes, sample size of 3 spools as far as the errors go.


Everywhere that I read about the physics of Gigabit and cable length - 120 Meters is pushing the design (or by some standards, well beyond the design limits). My scenario validated the "theory" quite well. It is also hard for me to believe that the console or AR's are at fault since it was consistent across an AR2412 and two AR84's plus with just the shortened length, 0 errors.


Anyways, we are happy now and have run 6 large events with 0 errors.

Good to hear its working for you now.  I didn't want to push the limits so I bought a 300' and a 150' from TMB.  I have been extremely apply with them and have never had an error.  Only once have I been at the end of be 300' piece.  I think it is the pretty much the longest length needed for my business.  I use the 150' piece a lot more often.

Works great using TMB ProPlex PCCAT5EP:

This is shielded stranded Cat5e.

I'm running 100' and 200' lengths with Ethercon connectors.  This cable is officially supported by A&H:

Running the same cable for our iLive system (IDR32 -R72) 100 meters lengths (328ft) with ethercon connectors, works perfectly.

Running 150' whirlwind cat5 ether snakes 2 are 6 +2 ethercon models and 1 is a12/4/2/150. I just ordered a 200'. I don't think they as shielded. I checked with guys on here to see if anyone had used them bore ordering even though they are not officially supported by A&H. We like them a lot.

Mark McFarlane:
I've used both 100' ProPlex and 150' Duracat, both with Ethercons, between GLD and AR2412 for a few shows without any problems. 

Very little to no static electricity where I typically work.
