After some brief investigation, it appears this DiSEqC switch is using a non-standard? scheme, which is not supported by w_scan nor vdr. Correct me if I'm wrong. To get the switch working with VDR I need an option to turn off the switch power. This is part of the sequence to program the switch. I've attached patches for w_scan and VDR to work with the DiSEqC switch I've got. I don't have any documentation on the switch. All the programming was the result of two days of reverse engineering. And I did not open the switch either :-) Manufacturer homepage: http://www.kjaerulff1.com/en-gb/p/30_maximum_diseqc_41_switch Information needed for VDR's diseqc.conf # # Full sequence for LNB-A # LNB.A 11700 V 9750 t F W45 v W15 W45 F W45 v W15 W45 t W45 LNB.A 99999 V 10600 t F W45 v W15 W45 F W45 v W15 W45 T W45 LNB.A 11700 H 9750 t F W45 V W15 W45 F W45 V W15 W45 t W45 LNB.A 99999 H 10600 t F W45 V W15 W45 F W45 V W15 W45 T W45 # # Full sequence for LNB-B # LNB.B 11700 V 9750 t F W45 v W15 [E0 10 26] W45 F W45 v W15 [E0 10 26] W45 t W45 LNB.B 99999 V 10600 t F W45 v W15 [E0 10 26] W45 F W45 v W15 [E0 10 26] W45 T W45 LNB.B 11700 H 9750 t F W45 V W15 [E0 10 26] W45 F W45 V W15 [E0 10 26] W45 t W45 LNB.B 99999 H 10600 t F W45 V W15 [E0 10 26] W45 F W45 V W15 [E0 10 26] W45 T W45 # # Full sequence for LNB-C # LNB.C 11700 V 9750 t F W45 v W15 [E0 10 27] W45 F W45 v W15 [E0 10 27] W45 t W45 LNB.C 99999 V 10600 t F W45 v W15 [E0 10 27] W45 F W45 v W15 [E0 10 27] W45 T W45 LNB.C 11700 H 9750 t F W45 V W15 [E0 10 27] W45 F W45 V W15 [E0 10 27] W45 t W45 LNB.C 99999 H 10600 t F W45 V W15 [E0 10 27] W45 F W45 V W15 [E0 10 27] W45 T W45 # # Full sequence for LNB-D # LNB.D 11700 V 9750 t F W45 v W15 [E0 10 27] W45 F W45 v W15 [E0 10 26] W45 F W45 v W15 [E0 10 27] W45 F W45 v W15 [E0 10 26] W45 t W45 LNB.D 99999 V 10600 t F W45 v W15 [E0 10 27] W45 F W45 v W15 [E0 10 26] W45 F W45 v W15 [E0 10 27] W45 F W45 v W15 [E0 10 26] W45 T W45 LNB.D 11700 H 9750 t F W45 V W15 [E0 10 27] W45 F W45 V W15 [E0 10 26] W45 F W45 V W15 [E0 10 27] W45 F W45 V W15 [E0 10 26] W45 t W45 LNB.D 99999 H 10600 t F W45 V W15 [E0 10 27] W45 F W45 V W15 [E0 10 26] W45 F W45 V W15 [E0 10 27] W45 F W45 V W15 [E0 10 26] W45 T W45 Good luck!
