Tvheadend

I use geniatech NetStream ATSC Tuner. This tuner is very restrictive because it can use by private application. But I want to add this tuner On tvheadend IP-SAT Tuner. Can I get a help anyone succeed Connect tuner in tvheadend?
There is tuner's description.xml , So connect tvheadend maybe able.
But ssh don't access this tuner. I think upload firmware first.
