The Doc says that if I have a PMDX-126 (Rev C) , an ESS and a PMDX-107, I have to power the ESS from a separate 5v supply. Is that still true? I thought I heard Steve say that was no longer a problem, but I may have imagined it.
If still true, which jumpers do I need to open? J3 and J4, but I thought there was a third one. I'm looking through the doc now but haven't located that info yet.
