Help - LNB required for Second Receiver

[gymant]

I have a SV360 Elite connected to a DN 500 dish with a Dishpro Plus lnb (110, 119). I added a second receiver a nFusion. Everything works fine when using either receiver, but not together. From what I read the Dishpro Plus cannot power 2 receivers simultaneously. Is that correct? If so, could anyone please tell me if a Dishpro Quad would do the trick? Or what you would recommend.

A few of the post I’ve read recommend attaching a dpp 44 switch with a power supply. Would it not be more cost effective to just replace the LNB with one that would power two receivers?

Thanks for your assistance.

No, it isn't correct. The receivers power the lnb, not vice versa. Most often when you have multi-receivers on an lnb, problems are caused by improper or poor grounding. Chances are if you ground your cabling, the issues will disappear.

Thanks stman, I'll recheck the grounding.

I read the below article in “Identify your LNB”

Since the DishPro PLus Separators passes control codes back to the switch from only one of its out puts, and one receiver has no way to know what channel is needed by another, DishPro Plus can not be used to connect two individual receivers.

That how I came to believe that the lnb was the culprit.

Did you run a new cable to the LNB, or are you using a separator to split the line?

Pictured is a DPP Separator. It looks similar to an SW21 or DP21. They are typically placed behind a receiver in a Dishnet installation to operate a dual tuner receiver on a single feed. The only FTA receiver that can use them is the SV Elite. Both feeds must go to the dual tuner receiver as the other feed will not operate another box.

Yes, I have individual coax cables runs from each receiver to the lnb. Also, I have a dp Plus separator for the SV360 Elite duel tuner.

If you had a Dish 500 with two receivers, which lnb would you use to fire up both receiver simultaneously?

Thanks for your input.

The LNB on the Dish 500 will run two receivers at the same time, I have a feeling it's an issue with your settings, or improper/non-existent grounding.

The DP LNB's have internal Diseqc switches, this means you still have to set your satellite menu settings to Diseqc port 1 for 119 and Diseqc port 2 for 110, this has to be the same for all attached receivers.

If you use an external Diseqc switch the same holds true for them.

The DP+ LNB has the same switch assignments.

Agree the LNB has an internal DisEqc switch. Each receiver is set to Sat 119 port 1 and Sat 110 port 2.

If the power weren’t sufficient, would the DishPro twin or quad LNB fix the low power to each receiver? They indicate two receiver capability and in the case of the quad four.

Thanks for your input.

The lnb being able to support the units isn't the issue as I explained before. The lnb 'powers' nothing. :) This is an issue of conflict between the receivers. I doubt changing the lnb will change anything.

[stman]

Have you tried removing the DPP separator from the SV to see if that changes anything?

[gymant]

Problem Fixed: On the advise of stman I concentrated on the receiver configuration, once I replaced the DPP Separator the signal to both receive held strong, at least for the past hour. All Smiles, thanks to all.

I'm glad that solved it for you. I still think that it indicates a grounding problem. That extra connection to the SV was causing it to dominate the lnb. JMO

Now comes the problem as to needing more LNB outputs to run the dual tuner at the SV 360 Elite, using the DPP separator will get you back to the problems you had before, and the current LNB does not have enough outputs to run both receivers with the Elite needing 2 and the nFusion needing another.

You can go with a DPP44 switch, this will give you 4 outputs, you run 2 out to the Elite and 1 to the nFusion.

Or you change your current LNB to a DP quad this will give you 4 outputs also.

In any setup you will have to run a second coax to the SV 360 Elite to get it running right, as it looks like the control codes for the DPP separator from the Elite are spilling over to the other LNB output inside the DP LNB, this is confusing the nFusion and it doesn't know what to do.
