This kit upgrades BK120S and BS120S and older BitScopes to BS220N standard.

It includes VM-220, the BNA-01 network adaptor and other components that should be replaced in these BitScopes to enable high speed network operation.

If you do not need networking we recommend the BU220U USB upgrade (or BU220S serial upgrade if you want to use your own USB to Serial cable instead).

Upgrade instructions are available here.
