How to hook up more than 4 LNBs?
Hi,
I'm thinking of starting a dish farm. (heh)... so with a regular DiSeqC switch, you can hook up four dishes at one time...
What if you need more, say 6,7,etc dishes (two extra dishes), what can you do?
Can you daisy-chain two 4-port DiSeqC switches together somehow? Or what's this 22-khz switch thing, what's that for/about?
....

check sadoun.com under technical support multi dish and receiver installation should explain the switches you will need.

Diseqc and 22 Khz switch connections for 5 to 8 LNBs

I've seen drawings on another site where a single 2-port 22 Khz switch connects to two 4-port diseqc switches. The Sadoun drawing shows one 4-port Diseqc that connects to four 2-port 22 Khz switches. Assuming both methods work, is there any advantage to one over the other? |

most 22k switches will not pass diseqc commands so the 22k first theory doesn't work. Been there tried that
I use to have 4 4x4 multiswitches go to 4 4x1 diseqc switches. 4 recievers running 8 LNB's

I have not done this myself (yet), but have read the way to do it is with a "committed" diseqc switch connected to an "uncommitted" diseqc switch.
I searched google.com for... committed uncommitted diseqc
...and found this...

The ecoda brand 22k switches pass the diseqc commands fine (or at least well enough for controlling 2 separate diseqc switches). putting the 22k switches after the diseqc works well too (any brand), but you'll need 1 22k switch for every lnbf you add. You might also check some of those nifty switches that allow you to connect a ton of lnb's to them and then reference them as diseqc posititions (satellite positions) instead of ports
