Configuration-->DVB inputs-->TV Adapters
Select the DVB device in the list on the left and in Parameters section on the right change the satellite config to Advanced(non-Universal LNBS, rotors etc). Hit save. The page will refresh.
On the left Select Advanced and in the Parameters section enter the number of Orbital Positions or Satellite configurations you wish to use. You can add more later on at any time if need be. Hit save. The page will refresh.
You will now see Orbital positions on the left. Select one and configure the parameters. C-Band is now available as an LNB LO option. Generic is for Diseqc. You have to assign a network to it before it will tune anything. You add networks on the Networks tab. Just hit add and choose type DVB-S then select the options you want for the network and hit create. Probably want to name the network to match the satellite. When you add muxes with the frequency to scan later on you'll choose that network. Any way, for now you have selected C-Band LNB and Generic switch. Hit Save. The page will refresh.
Now on the left in the orbital position you'll see generic. Select that and on the right in Parameters you can specify the diseqc switch configuration. Then hit save.
