According to the DiSEqC "Application Information for Tuner-Receivers/IRDS",
page 13, may setup should be correct.

The relay is configured to react on DiSEqC "Option A/B", and according to
the DiSEqC specs the values F0..F7 imply "Option A", while F8..FF imply
"Option B". So with a sequence like

   [E0 10 38 F0] W100 [E0 10 38 F0]

the first [E0 10 38 F0] goes to the relay, which switches to the first
switch (Option A), then (after 100ms) the same sequence is repeated and
reaches the switch. The switch then goes to satellite position A, polarization
V, frequency Low.

The dvb-kernel driver works fine now with hw_sections = 0 (see the other
postings in this thread).
