...@MarkConsidering the guy who posted the 'official' response from Behringer suggested a ProCo cable, maybe it doesn't matter. We'll try to recrimp with the metal RJ45s if possible, but if we can't we'll see how things turn out.
I made a mistake last night posting, the open cable was a Rapco Duracat 150NN (6e) Ethercon cable, not ProCo. I have edited my original post. I have no knowledge of the ProCo cables.
Hate to throw more problems in to this
Hate to throw more problems in to this when it sounds like its figured out. I have and X32 with two S16 as an up-fit(one in the amp rack and one mobile)and started to have dropouts. I was waiting on Behringer to spec a cable for reinstall the UTP to STP when I figured I would test with some production style STP to confirm others findings. I found when using 150ft of ProPlex shielded (foil with drain) cable I could still cause the drop out via the electronic igniter from a lighter. My video is a bit poor but you can see all the import thingshttp://youtu.be/H_cTXA9kNvY Things I found in my testing to try and avoid reinstall cable-shocking my X32 I could not make the sync drop with any style cable/connector. -using Behringer loop back test (connect port a and b of the same unit together) I could make the S16 drop with all cable/connectors but never made the x32 drop. -Using Ferite beads to UTP is as effective as shielded cable with no ethercon.-adding grounds and removing grounds changed nothing-changing clock master to the s16 changed nothing-adding a dn9610 into the mix changed nothing-verified with a multi meter.... the ethecon makes a better connection from the shielding of STP to the chassis ground.
1: How do you add ferrite beads to a UTP cable?
2: Since Brian earlier posted that an STP with no Ethercon is ineffective, does that mean the ferrite beads are equally ineffective?
3: Who put the connectors on the cable, and was it then tested to meet spec?
4: Were the dropouts happening to both the amp rack mounted S16 and the loose one? You only showed the loose one in the video.
-they are snap on style I had floating around. For reference they have a KG logo and RFC-13 and the core measures 1.1in long with an ID 0.57in. wire wrap one time around with a loop about 3 to 4ins in the hope of not bring the cable out of spec.-the UTP with beads does not make it immune to drop outs so yes it is ineffective, but I did see an improvement in the ability to withstand ESD as seen with STP without ethercon. My S16 drops on the first or second hit of the electron igniter on UTP, but I had to work harder to make it fail with the beads on the UTP. It also synced back up faster then the plan UTPSNIP
Hi Morgan,Hope your month-long show is going well, and thanks for this info.Based on the glimmer of hope you offered here about ferrite beads, I asked my AES engineer buddies about the problem Saturday night at a gathering we had, and they said that yes, adding ferrite beads might fix the problem.I got some of these http://www.amazon.com/gp/product/B007Q94CJS/ref=oh_details_o05_s00_i01?ie=UTF8&psc=1 , along with a large ferrite core that one of my friends happened to have there, and modified a BBQ sparker to provide the spark. That one is about half the size of my fist, with about an inch hole through it.The cable is a Gepco Tactical Quad Ethernet cable (four CAT5e UTP with individual jackets, all inside a larger, thicker jacket). The four CAT5e's were prepared as follows:- one with one ferrite bead on each end;- one with two beads on each end;- one with the large core on the S16 end and with the cable going through the core and then looping through again once (all that would fit through without taking off the Ethercon), with nothing on the console end since I only had one;- no beads on the fourth one as the reference.Cutting to the chase, all of them showed loss of sync, with the large cored cable taking a bit longer to do so and needing more of a hit to lose sync. But it still lost it.Connecting a Proplex shielded version of the same thing, it didn't lose sync no matter how long you hit it with a spark (my BBQ thing is battery powered and sparks as long as you hold the trigger).Rats. I don't see any hope here for using existing UTP. As I said earlier itt, the quad Proplex is much too stiff and unwieldy to use, at least in my scheme of things, and I feel the need for redundant cable runs so that a quad cable is perfect. The Gepco doesn't come in STP, and I haven't found any besides the Proplex.Phooey.
I'm glad that my results are being duplicated. Shielded is the ONLY way to go.
