The Ross NK-SCP/K2 allows Kondor 2 Routing Systems to be extended by using NK Series routers. Any combination of NK Series routers can be added to a Kondor 2 system with a maximum size of 255 inputs and 255 outputs with up to 8 levels. Kondor 2 inputs, outputs and levels are directly mapped to NK Series inputs, outputs and levels, with no user mapping required.
