Have two issues.

1) Can only set one pool.

2) All but 1 of my units have stopped working after trying to change the the miner settings. I have tried setting eco, balanced and even advanced with power from min to 45%. Only  One unit will work when I make these changes but the rest will not function at all. Even the main controller will not function with no unit connected and shows the default config with default pool.
 
Update: I was able to now get some units working again by connecting each one to the USB 1 port and booting the units individually. All but 1 of the units are now working. I will try connect the still bad unit to a PI and run it on its own.

Any advice would be greatly appreciated.
