I do not see how the ports could interfere with each other. Your switch
provides 4 independent 1-of-3 switches and each of your 3 LNBs provides
4 independent 1-of-4 switches.

I've had a look at the source code today. kaffeine "uses" a VDR
diseqc.conf like this one:

S19.2E 11700 V  9750 t v W15 [E0 10 38 F0] W15 A W15 t
S19.2E 99999 V 10600 t v W15 [E0 10 38 F1] W15 A W15 T
S19.2E 11700 H  9750 t V W15 [E0 10 38 F2] W15 A W15 t
S19.2E 99999 H 10600 t V W15 [E0 10 38 F3] W15 A W15 T

S13.0E 11700 V  9750 t v W15 [E0 10 38 F4] W15 B W15 t
S13.0E 99999 V 10600 t v W15 [E0 10 38 F5] W15 B W15 T
S13.0E 11700 H  9750 t V W15 [E0 10 38 F6] W15 B W15 t
S13.0E 99999 H 10600 t V W15 [E0 10 38 F7] W15 B W15 T

S28.2E 11700 V  9750 t v W15 [E0 10 38 F8] W15 A W15 t
S28.2E 99999 V 10600 t v W15 [E0 10 38 F9] W15 A W15 T
S28.2E 11700 H  9750 t V W15 [E0 10 38 FA] W15 A W15 t
S28.2E 99999 H 10600 t V W15 [E0 10 38 FB] W15 A W15 T

I also had a closer look into the specification and into the
implementation guide. There is only one mandatory command for DiSEqC
1.0: the above used 0x38.

Bye.
