It says it has two tuners. The card appears to have two connectors. Are they BOTH for LNB in? So one could be a KU LNB and the other a C LNB? Does this card provide power to the LNB? And if I have two LNBs input, one to each connector, does it power BOTH LNBs? Is there a LINUX driver? I would use my DSR-922 to position the dish and power the polarizer, but I would not connect any LNB to the DSR-922. Is this OK to do this? I'm thinking that the DSR-922 would select the correct polarizer setting based on TP selected on the DSR-922 even though it would not actually be connected to the TP. I will use the TBS-6902 display on my PC to visualize signal strength while using the dish positioner and polarizer control on the DSR-922 to fine-tune. Thanks all.
