But wouldn't this mean that, if Switch 1 is currently at ZF 2 and I want to
tune to a channel on ZF 3, the following would happen:
- The first sequence of E0 10 38 F0 goes to the relay as well as Switch 1,
so the relay switches to Switch 1 (which it already was, so no change),
and Switch 1 will switch to ZF 0 (which is not what I want).
- The second sequence of E0 10 38 F2 also goes to the relay as well as Switch 1.
For the relay there is no change, because F0..F7 all mean "Switch 1".
The Switch 1 however now switches to ZF 3.
So, unless I'm missing something, with your setup the switch would go
through extra stages that are not intended.
Besides, wouldn't a sequence of [E0 10 38 F8] W100 [E0 10 38 F3] first switch
the relay into "Option B" (F8) and then back to "Option A" (F3)? After all,
_all_ DiSEqC sequences go to both the relay _and_ the switch. The repeating
is only done because the switch might have to power up if the relay newly
switches to it in order to actually see the (second) sequence. AFAIK it is
not so that the first sequence goes only to the relay and the second one
only to the switch.
