Oops, of course you are right, because off all the guessing of your
hardware I had mainly this setup with a mini-DiSEqC relay in mind:

S19.2E  11700 V  9750  v A W100 [E0 10 38 F0]
S19.2E  99999 V 10600  v A W100 [E0 10 38 F1]
S19.2E  11700 H  9750  v A W100 [E0 10 38 F2]
S19.2E  99999 H 10600  v A W100 [E0 10 38 F3]

S21.5E  11700 V  9750  v B W100 [E0 10 38 F0]
S21.5E  99999 V 10600  v B W100 [E0 10 38 F1]
S21.5E  11700 H  9750  v B W100 [E0 10 38 F2]
S21.5E  99999 H 10600  v B W100 [E0 10 38 F3]

In the mail I changed some items without a deper thought about a real
DiSEqC relay.
Sorry for the confusion.
