Reverse band LNB - 13 or 21 tuners

here goes with a definitive (partially) response. Not a guess. If you go to sat setup, at least on my HR44, and you have a 21 tuner Reverse Band LNB, a message pops up that says:
"If a network has at least one NDS, Hx2x or HR34 only 13 SWM channels can be used".
No mention of H25s.
And it must be firmware-related because my HR24s running CE software work perfectly on my 18 tuner setup.

 

What is meant by NDS? Usually in context of D* that refers to the former company now a part of cisco but that wouldn't make sense.

 

NDS is the company that made the software that runs on SD receivers like the D12 and R16, which are SWM capable. (Any previous D1x and R1x models, as well as pre D/R/Hx-era receviers are not SWM capable and can only be hooked up to Legacy ports, so they are not part of the SWM tuner count)

People have reported problems when experimenting with the newer LNBs where the receivers listed in that warning had problems if certain SWM channels were already taken by other receivers, which would be a problem after a power outage and they didn't boot up in the right order.

 

I had no idea that NDS did the SW for the sd irds.

 

Here's what I found based on personal experience.

If the LNB is a "first gen", starts with 3D1 in the model number, you'll only get 13 tuners. If you have a "second gen", starts with 3D2, you'll get 21.

When I bought my RBLNB the Ebay Seller mistakenly sent me a 3D1RBLNB and I only got 13 tuners. When he corrected his mistake and sent me a 3D2RBLNB I got 21.

 

Maybe he set them up wrong in the menu? If he set them to SWM3 and not RB2 maybe? I don't know because I haven't used any with more than 13 tuners yet.

 

slice, opened a thread based on sg's FUD ? tsk,tsk,tsk

not before get info from SECOND other knowledgeable source, perhaps here

 

They auto detect. You can't set them up wrong.

 

Yes, it auto detects the Reverse Band LNB. The only thing you have to do is to go through sat setup completely if you are going from a 5LNB to the 3LNB reverse band.

 

Hx2x includes H25s as well as anything else with a H and a 2 in it.

 

Yes, after I posted I realized that....

I suspect this issue is IRD firmware related, and not the LNB itself. That might explain why the HR24s I have running CE software work fine in a 21 tuner configuration, and why the poster over at sat guys has some H25s that work and others that don't. But it's still all speculation.

 

I have setup 5 of these so far and they don't auto detect like a swm3 would. You have to pick the proper LNB from the drop down.

 

Mine autodetected fine. But if your current LNB is an SWM5, you need to go through sat setup completely and select from the dropdown otherwise the IRD thinks you still have a 5LNB

 

I've setup 2, both auto detected.

 

Ditto It wont let me manually change it

 

How would that have really been possible though?

Aren't all SWiM LNBs auto-detected by the receiver from the drop-down selection menu in the setup and then grayed-out to where it can't be changed manually?
