From what I can remember its diseqc 1.1 on both. I basically am pointing at 13e and 19e using the monobloc and 28e on a minidish. 13e on diseqc 1, 19e on diseqc 2 and I have 28e on diseqc 4. These are the settings I use on the azbox (at work at the minute so cant confirm)
The azbox is set up so that each 'antenna' has its on diseqc number (as shown above) and so when I choose the channel from the eps it automatically sends the diseqc commands and switches to the correct lnb.
