cascading SW44 switch for 5+ tuners - Page 14 - Canadian TV, Computing and Home Theatre Forums

So Pinza, your telling me that i cannot do this? I dont understand why the splitter is working for a second SW44 (See first post of this thread) and would'nt work with the receiver.

That is correct. I am telling you that as well. You could put a SW24 or SW34 ahead of the SW44 (2 inputs from the 91 LNB and two outputs to the SW44.) That will leave two outputs on the SW24 for up to two SD receivers.

Pinza · 2010-08-16, 04:45 PM

Yes I most certainly am, as Scary says.

As for why, the SW44, dedicates each input to a side of an LNBF;

1a outputs 18v giving even Transponders on the LNBF (91)
1b outputs 13v giving odd Transponders on the LNBF (91)
2a outputs 18v giving even Transponders on the LNBF (82)
2b outputs 13v giving odd Transponders on the LNBF (82)

So any splitter on an input MUST be fed by the same voltage. On a second SW44 it would feed the other INPUT 1a with 18v on the same LNBF.

Therefore each side of an LNBF is always fed by a constant voltage giving either odd or even transponders depending on that voltage.

Now looking at your drawing, you could use the splitter to feed the 2700 but as soon as you choose an even Transponder the 2700 would output 18v (The splitter already has 13v) and would then effect the 1a Input to the SW44. It is impossible to have 13v & 18v on the same coax, so the higher voltage would most likely win and all receiver tuned to an odd Transponder via 1a of the SW44 would then be switched to an even transponder due to the higher voltage on the input.

Hope that makes sense.......

I will read it again after a few beers and chack it.....lol

I all,

Just to let you know the result of the test that I did (ref: post 192 - 195) with the Eagle Aspen S-2140-CE as a SW34. Testing was done for the solution on post #3 and it is working well.

Question:

From the SW34 to the LNB, is there specific assigned connector on the LNB for the 13v and 18 V ?

Have a nice day.

Pinza · 2010-08-19, 03:41 PM

It is the SW34 that assigns the voltage that is then passed to the LNBF, most have the voltages written on them alongside each SAT input.

mhyndman · 2010-08-22, 10:29 PM

i have an s34 and an s44. Can I get use of 2 9200's and 1 sd reciever with these 2 switches? If so, can you tell me how to hook it up. Maybe even include a diagram?
Thanks.

Pinza · 2010-08-23, 07:47 AM

2 lines from the 82 LNBF feeding Inputs 2a & 2b on the SW44.
2 lines from the 91 LNBF feeding a 4 Way switch. 2 Outputs from 4 Way switch feeding Inputs 1a & 1b on SW44.
2 remaining Outputs from the 4 Way switch to SD Receivers.
SW44 can then feed 2 x 9200's with Port #1 having the Power Inserter on it.

mhyndman · 2010-08-23, 07:53 AM

Thank you Pinza. Is there an easy way that I can tell which lines at the switch are for which satellite if they are not labeled or do I have to trace them back to the dish?
Thanks again

Pinza · 2010-08-23, 08:01 AM

I would trace them back, also I would be moving the Switch's indoors too, if possible.

That way you will just have 4 lines into the house, making identifying them easier during any future troubleshooting.

mhyndman · 2010-08-23, 08:07 AM

Thanks again. The switch is inside. Just not labeled by the original installer. One of many things he did wrong, hence why I want to do it myself this time. Thanks to forums like this I can.

classicsat · 2010-08-23, 09:16 AM

If possible, bring a receiver and TV down to were the switch is, if possible, and conect the receiver to each line and run a check switch on them, to see what satelllite they are for.

Pinza · 2010-08-23, 05:08 PM

So you have the SW44 already hooked up, in that case 1a & 1b will be 1 Sat and 2a & 2b will be the other Sat.

As classicsat says, try just hooking up a Receiver to any 1 Input see which LNBF it is by doing a Check Switch from MENU, 6, 1, 1 or with the receiver on the Signal Strength Screen, if the Dish is accesible, get someone to watch the Signal Strength and cover the LNBF face with your hand, when you loose Signal, you can then tell which LNBF is on which Inputs.

mhyndman · 2010-09-05, 04:29 PM

Thanks all. I finally found the time today to carry this out. It all works fine except my 2 9200's do not get 549, 550 or 551. (there may be other but this stands out now as they are kids channels). The SD receiver does get these channels. Any suggestions as to what is happening and what I can do to correct the problem?

Pinza · 2010-09-05, 04:31 PM

I would just suggest a re-hit from Bell.

mhyndman · 2010-09-05, 06:34 PM

Pinza, you have been great help so far. Thanks again but I just spoke to Bell. The walked me through trouble shooting and came up with that I was not getting a signal from the "odd" transponders from the 91. I just re-read your first post to me regarding this. You suggested....
2 lines from the 82 LNBF feeding Inputs 2a & 2b on the SW44.
2 lines from the 91 LNBF feeding a 4 Way switch. 2 Outputs from 4 Way switch feeding Inputs 1a & 1b on SW44.
2 remaining Outputs from the 4 Way switch to SD Receivers.
SW44 can then feed 2 x 9200's with Port #1 having the Power Inserter on it.

If I have the 82's and 91's mixed up could that be a cause?

Bell suggested that the best I could do was 5. I know that was myoriginal request but if I can get 6 I'm all the happier. here is what Bell said to do....

All 4 sat cables to sw44.
out 1 and out 2 to 9200
out 3 and out 4 to sw34
out 1 of sw34 to sd receiver
and out 2 and out 3 of sw34 to 9200

Any thoughts?
