Despite the switches being the same model and bought at the same time each one responds to a different set of diseqc commands to change LNB.  IIRC one seemed to behave as a cascade of 2-way switches, the other responded to the more usual commands for a 4-way switch.

How you determine which number corresponds to which card is left as an exercise for the reader (hint: the margin may not be big enough).  These defines are placed in 'diseqc-multi.conf' and start with the card number but are otherwise the same format as those found in 'diseqc.conf'.

Dear Klaus, all,

That sounds good.  Using this proposal I would configure my system with the following diseqc.conf:

# diseqc.conf

S28.2E a1...
S28.2E a2...
S28.2E a3...
S28.2E a4...

S19.2E b1...
S19.2E b2...
S19.2E b3...
S19.2E b4...

S13.0E c1...
S13.0E c2...
S13.0E c3...
S13.0E c4...

2:

S28.2E A1...
S28.2E A2...
S28.2E A3...
S28.2E A4...

S19.2E B1...
S19.2E B2...
S19.2E B3...
S19.2E B4...

S13.0E B1...
S13.0E B2...
S13.0E B3...
S13.0E B4...

# EOF

where [a-cA-C][1-4]... are diseqc command sequences.

If I understand correctly, with Klaus' proposal my 'normal' switch (card 1) would use the [a-c][1-4]... commands, and my problem switch (attached to card 2) would use the [A-C][1-4]... commands.  Any additional cards would also use the [a-c][1-4]... commands.

Unless I have understood incorrectly this gets my vote, if someone implements!
