I'm trying to understand your actual diseqc setup from the tables you 
attached -- you have two cards, each with a single diseqc switch that 
has a single universal LNB attached.

[card1] ---- [2 port switch] --- (port 1) --- [universal LNB]
[card2] ---- [2 port switch] --- (port 1) --- [universal LNB]

Is there actually something on the second port of that switch that you 
just haven't defined yet, or for future expansion or something?

Do those cards actually have separate hardware (i.e. two sets of 
switches and LNBs), or are the cards chained or otherwise connected to 
the same devices?
