Lnb Unicable compatible in TBS6905 and Tvheadend?

[ArraY]

1-How to activate unicable-support on Linux in TBS6905?
2-Do I have to plug in only one cable to an input on the card (In what number of input would you have to connect) or do I have to buy a splitter to have four outputs and plug four cables into the card?
3-In tvheadend how do I have to configure the tuners so that the unicable system works for me?

Thanks

Need 4-input splitter (with diode pass-block circuit, usual marked as satellite splitter 950-2150MHz).

P.S. TBS 6909/6909x support reception up to 8 transponders from one input (unicable or single-cable from one sat pol/band).

And in tvheadend the config how to?
¿In parameters->satellite Config->universal lnb Only?
