I also have problems with 4 quad LNBs on a diseqc switch (1.0 and another 2.0) If I plug out the cable from the card and plug it back again (reset switch and LNBs) I can use szap to change the channels. I believe the quad LNBs have diseqc switch inside and at reset they are in backward compatible mode (Tone/Voltage). In Diseqc specifications/recommendations they recommend the diseqc LNB should ignore responding to Tone/Voltage commands when they receive one diseqc command. Unfortunately, I did not find the proper diseqc commands for the LNBs. I will try today a workaround to reset the LNB before sending the diseqc.conf sequence in backward compatible mode: - switch to another LNB (hope the power will be cut for the one I need for the channel) - do the sequence for current channel t v [E0 10 38 FF] W500 (switch to LNB4 and wait 500) [E0 10 38 F0] W100 A W15 t (switch to LNB1, wait for power to stabilize, use back compatible) If I am lucky enough the switch will cut the power for the LNB1 when I switch to LNB4. Does anybody knows the Diseqc commands for Quad LNBs??
