Is there a picture of exactly how the LNB's connect to the 4x4 switch? In looking at the inputs, I am a little confused as to how to wire everything up.
you need dual LNB's. Each 4x4 multiswitch has 4 inputs labelled
13v, 18v, 13v+22k, 18v+22k
you would hook both lines from the dual LNB to the switch
1 LNB gets hooked up to 13v & 18v
2nd LNB gets hooked to 13v+22k & 18v + 22 k
repeat for all 8 LNB's
I am also interested in exactly how each 4x4 is hooked up to the DiSEqc switches and how the receivers are programmed for each position.
what I do is label the multiswitches 1,2,3,4. I use the same output number from each switch to the same receiver to not confuse me
run a cable from the output of each multiswitch to a port on the diseqc. So the 1st output from multiswitch 1 hook into port 1 of the diseqc, 1st output on 2nd multiswitch goes to port 2 on diseqc, and repeat. I make sure to use the same output from the multiswitch so if there is an issue, you know that receiver 1 always has the 1st port of the multiswitch.
Programming is easy
1st multiswitch is diseqc 1
2nd multiswitch is diseqc 2 etc
the LNB attached to the 22k side would be DIseqc 1 22k on
I am curious how each position on the rail is wired into the switches and then referred to in the receiver.
that's up to how you label and wire them
It seems like it would be somewhat complicated thing to get setup, especially if you would need to do a factory reset which would entail repeating the setup exactly!
no need for factory reset...its just changing some info in the menus
