  1. David, Thanks for the reply. Yes, it is the Intelix Digi-USB unit that I'm using. It's on demo from them, so I can test it in this application for our field engineers. When talking to Intelix's techs they thought I might be having issues do to voltage loss, meaning the DSIs needed a powered hub (much like your posting recommended). However, I found no change when applying power to my hubs to when I was using them unpowered. It still only recognized 7 over the Intelix unit and 8 locally. - Note: I am using three 4-port hubs linked together to give me enough ports to have all 8 DSIs online at once. So far though. My limitation has been 7 amps at once over the Intelix unit because Windows says it has exceeded the maximum bandwidth. In system properties the Host Controller for that USB is at 94%, so possibly that is why it will not initialize the 8th amp ("failed to start" error in system properties). However. 7 is still stellar. And with the price tag on the Intelix unit at $190 MSRP, it looks like a great tool for our field engineers. The only issue I've ran into now is, once on two different laptops I was testing with, they have lost network connections while being connected to the amps. I don't know if this is related to SA or Intelix or neither. Both had to reenable the adaptors to get ethernet again. I'm trying to dive more into that one. Thanks again.
  2. Finally! We've been waiting to test out multiple DSI's (CDI, XTI...) via an USB hub. Today I finally had the chance, though it was a few hours in the shop, but I think this will be greatly beneficial out in the field for our engineers. Here's what I did, and the few problems I ran into: Stuff on hand: 8 DSI's, all with old firmware. Three 4-port USB 2.0 hubs, non powered. Intellix's USB over ethernet bauln. 100' Cat5e First off, I had to update each DSI with the new firmware, one at a time or Windows will blue screen. Time consuming. Second, I connected all updated DSI's to the hubs all linked together and connected to SA. (First problem here) SA ran into multiple addressing problems where alot of the time it tried to call multiple amps by the same name 'Amp 1', which lead to communication problems. I tried to auto address randomly, but because of communication problems it would hang up 'waiting on response'. So I, thirdly, went back to connecting to each amp one by one. Giving each a manual address number at this point. (Second problem here) Though sometimes those that all were still trying to be named 'Amp 1' would not recognize completely. I found powering off/on the amp fixes that. Sometimes coupling with restarting SA also helped. This one was hard to troubleshoot. Fourthly, with each of the eight amps having a different address, I reconnected to the daisy chain of hubs, hooked to my USB port and viola - They all appeared and no blue screen. Now, Fifthly, when I connect at the rack straight to my computer I can see each of the eight amplifiers as online. (Third problem here) But when I connect to the Intelix extender, only seven show online and an message balloon appears saying I have exceeded the maximum bandwidth for my USB host controller. The Intelix extender works wonderfully, no lost connection, but apparently seven units are all it can handle. So, any ideas from anyone on the addressing issues, where I had to spend quite a while doing it manually. Or any ideas on increasing bandwidth to a USB host controller in Windows? Thanks!
