Re: USB cables RE: [BlindHandyMan] New Tool Review
technically it is true. The better cable, the better the transfer. I use digital audio as a reference. I *Know digital for the 16 bit 44.1 mhz of audio, and higher, will do better with a better cable. But that isn't where most folks are centered. The computer industry surely isn't centered there. It is hard enough to get *real audio folks to get past brand names, to some of the craziest things that you can replicate ; to finding the difference... the idea that a coat hanger is a good audio conducter is still near at hand. As long as Radio Shack sells a cable for less than $5; it is sadly a mute point. Now to the practical, if it is a critical or otherwise high demand app; you'll find that everything from the power supply, to the cards, shielding, and nearly every other point in the *separates used for the job, will be necessarily contributing to the final product.

Correct me if I am wrong but as a general principle if quality is a concern would you not think that the longer the travle data has to go the more you might be concerned about the quality that is needed to cary the data? I am not an electronics guy but it just seems logical.

This was at a local Big Lots store and didn't cost more than a few bucks. Anybody tells you not to use cheap USB cables, unless over a very long distance, is nuts, cheapies work fine. tom [Non-text portions of this message have been removed]

robert, I think Tom meant that cheap USB cables are just fine to use unless you are going long distances, in which case you want more expensive cables. -- Blue skies. Dan Rossi Carnegie Mellon University. E-Mail: [EMAIL PROTECTED] Tel:(412) 268-9081

Did I say it backwards? I meant, I think, maybe, that cheapie cables are fine except perhaps over long distances. Standing on it's little blind head. Tom
RE: USB cables RE: [BlindHandyMan] New Tool Review
Tom So just to clarify for me and others that are not that knowledgeable about elictronics. Would it be true that the longer the distance data has to travel the more important quality of wire needed, becomes? -Original Message- From: blindhandyman@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of Tom Fowle Sent: Thursday, October 04, 2007 12:45 PM To: blindhandyman@yahoogroups.com Subject: Re: USB cables RE: [BlindHandyMan] New Tool Review Did I say it backwards?

Re: USB cables RE: [BlindHandyMan] New Tool Review
robert, yep, the quality of the insulation is probably more important than that of the wire its self but that's nit picking. I think the USB limit is fifteen feet anyhow, so I doubt cables matter much in that length. Depending on the type of signal being sent, there are all kinds of issues that need considering like impedance of the cable, capacitance and inductance shielding etc. Of all of these, probably the actual metal that makes up the wire is least important as long as its copper. Silver plating only matters for corosionresistance unless you're into extremely high frequencies say microwaves,which USB ain't. Tom
