I think you need to read more about what Unicable is and does, and how it works.
In a legacy setup, your tuner uses DiseqC to select an LNB, and gets the entire selected frequency band (HL/HV/LL/LV) from the LNB, and it does the selection of the desired transponder frequency, it its processing.
In a Unicable setup, the LNB (if you have Unicable LNBs) or the switch will do the transponder selection, it will select an SCR to communicate with the tuner, and it will frequency-shift that tranponder to match the SCR frequency. Your tuner will just listen to that SCR and use whatever comes in, without any further tuning.
So, DiseqC is a legacy term/technique, and not relevant/used in a Unicable setup. It does not exist.
No I was told this from HM-sat that programmed the switch:
Hello, How DiSEqC was set up? Mit freundlichen Grüßen/Best Regards Wolfgang Beierl HM-Sat GmbH Deutschland
So maybe they don't know the product they are selling?
