On a separate note has anyone found where you can enable/disable the S7/S5+ Controller boards Data port? It would be nice to either upgrade firmware and enable more than 3 data ports...
have you tried just soldering on new male connectors and hooking up boards? if you leave one board unpowered the miner does not leave ------- if i'm not mistaken is just appears blank. so it may be safe to assume scaling the system up is just a matter of physically adding the parts themselves.
