The one they sell is 6'. I have them in 10' and 15' as well. Shorter is better. VFDs are noisy critters though, the USB isolator Greg is working on may be a good fit in your application.

OK I take it that no one knows what the reset on the SS does or how to implement it.

It has been answered at least twice in this thread, or are you meaning something different?

Well, I have already stated twice what it does, what the heck maybe the third time is the charm...It clears the flash memory. You have to have the jumper in place when the SS is powered up. It is something you will most likely never need to do.

Well I must apologise.  

"Clears the flash memory"    I guess I did not understand what that meant.

I was under the impression that the plugin in Mach reset the flash memory every time Mach booted up.

EDIT:  I reread Jeff's post number ten where he explained that.  First reading I was just seeing talk of noise elimination discussion and skipped over that bit.  Sorry.
