Point of clarity needed:
In the description of the A741 you talk about it using a controller (sold separately) connecting to the AUC3 device which in turn can of course link with up to 5 miners, max 3 AUC's per controller etc.
All standard for Avalons up to this line:
This driver is sold separately and is required for the operation of the AvalonMiner 741.
Does that refer only to the RasPi controller (sold separately as always) or is the AUC3 /link cable not supplied either? In the past each miner came with 1 AUC3 and 1 link cable.
