Hey,

Hopefully you can help me out with this one. I know that you can convert any Dishpro Equipment in a Legacy Environement with the Legacy Adapter, but will Dish Pro Switches such as DP34 work in a Legacy Environment with this adapter?

Thnx

You could use a DP LNBF and a DP34 switch with a 3900 receiver but you would have to have a DishPRO Adapter on the feed to the 3900. Using a Legacy LNBF and a Legacy Switch like a SW21 with a DP301 receiver requires no adapter.

Hope this helps,
Jason

DP44 has built in legacy adapter.

Yup, you are correct...but I based the example on the fact the original poster called out the DP34 specifically.

The term "Legacy Environment" is pretty confusing. You mean LNBFs, Switches, Receivers, some of that, all of that? And the next person that uses that term might mean something else entirely.

I'm going to assume you're talking about DP switch, but what type of LNBF? It/they MUST be DishPro.

I am talking about Legacy Recievers,

I wasnt aware the DP44 had a built in Legacy Switch.

Does a DP44 and SW21 work together, if working with a Dishpro -> Legacy Switch.

I am trying to think of alternative ways to get older satellite recievers to work on Dish Network...

Yes, the DPP44 has a built in Legacy Adapter.

You can NEVER mix ANY DishPro and Legacy 'outdoor' (LNBF, switch) equipment with ONE known exception that has VERY limited application.

The big exception is that you can use a FSS LNBF to drive a DP switch and get the ODD transponders of 105 or 121. Details if you really really want them.

So the Answer is yes then. You can use Dish Pro switches on Legacy Recievers, with the help of an adapter...

Yes Sir....DP21, DP34 can be used with a Legacy Receiver (4-Digit Model Numbers) with the use of a DishPro Adapter...A DP+44 (DPP44) can be used with a Legacy Receiver (4-Digit Model Number) without a DishPro Adapter since the DP+44 has the Adapter built in.

Now that's an interesting question. Since the feed from the DP+44 would be a legacy, I wonder if that would be possible. If so, you could actually use a legacy LNB on the SW21 in the mix with the DP LNBs....................

oooo. Now THAT is an interesting concept. Maybe alebowgm is on to something!

DP LNBFs ---- DPP44 ----> SW-21 ----> receiver (maybe not even legacy!)

No, I tried to run a DP Twin through an SW21 to see what would happen, and it ignored the SW21. However, I was wondering if there was a device that could bleed off some voltage from a DP line to give the odds a 13V lock on a legacy LNB like the way that one FSS LNB was hooked up 90 degrees off. This would be useful if you locals came on an odd trans and you had a switching FSS LNB instead of seperate H/V feeds.

No - the difference here is the SW-21 is talking to a DPP44, which I think looks like a SW64 when in legacy mode. So if a SW-21 will work with an SW-64, then there's a chance this will fly. It MIGHT require a real Legacy receiver that can't even try to enter DishPro mode.

Not sure what you're asking with the second half. I've thought about using a Legacy LNBF at 13V for odd-only - it should work fine, but there's no real point in it - just go with the DP LNBF.

If you MUST go for it, how about a splitter that is DC-blocking on one side (the DP feed) and just ram 13V up the other side. :)

Not neccesarily. The DP based receiver would sense that the switch is a DP+44 and probably ignore the SW21.

Ok, the DP sends out a 20V charge. Now, if you hook it up to a standard LNB, the LNB would send you the evens on the 950-1450Mhz band, and thus would be ignored by the receiver since it is the wrong set of trans. Now, if you could tap that 20V charge down to less then 15.6Volts, the LNB would sent back the odds, and it would work properly. OR, you could use a DC blocked splitter like you suggested and run a powered D* style MultiSwitch to run the LNB, and only hook up the 13Volt port.

That's why I said "It MIGHT require a real Legacy receiver that can't even try to enter DishPro mode.". ;) :p

The rest of your post is right on track with what I'm thinking.
