Dpp ?

I was doing an upgrade for a customer the other day. They we going from 2 old legacy receivers to a 522. Due to the way the house was wired I had to change out the LNB to a DPP Twin.

Now I have been told and have read on boards more than once that a Legacy receiver will only work if there is also a DP receiver also hooked up to a DPP. So I thought I would give it a try and see if 1 of the receivers would work on the DPP. Low and behold the old 2900 reads the DPP as an SW64 just like it should. It had no problem changing channels either. Now has anybody else tried this with an old Legacy receiver and gotten it to work?

What I am wondering is when the Dish1000 starts rolling out, if a Legacy recevier will be able to power all 3 LNB's. Has anybody tried that yet?

It's goofy, but I had a similar situation. A dishmover/installation with a 3900 Legacy receiver. The customer asked that I install a must-carry as well; Cleveland locals are spread out to the 61.5 as well as the 110/119. At any rate, I tried the whole "one legacy receiver to a DPP Twin and DP Dual" routine. And it worked fine. *knock on wood* No troublecall or anything thus far; and it's been going on 7 weeks now.

I was thinking it would work. Sure is alot better than an SW64.

Note that a Dish1000 is electronically equivalent to a D500+D300 (webbydude's job), so you've got a shot - but it IS unsupported.

The issue is likely voltage to the LNB. If the Legacy receiver is wanting odd transponders, it's going to send 13V, not the 18+V that DishPro wants.

So when hooking up a only legacy receiver to a dish 1000 would a DP adaptor fix the voltage problem and be a "supported" method?

No.

And remember - it doesn't apply to just a D1000. The key point is DPP-Twin.

No, not supported.

But yes, maybe!

Connect the DP adaptor (or other power insertion) to one port and legacy receiver to the other.

Keep in mind DP and DPP only require 12 vdc. But at more current than legacy can safely supply.

Hmmm. Didn't realize that DP could run on 12V.

Learn something new every day I guess.

Haven't been able to find the specs on it. This is based on my testing. It seems to check out when doing the worst case voltage drops on 200' of cable.

Its easy to check on my system. I have a DPP44 with power insertion near my test bench and no receiver fed from port one. I dropped voltage to +12 (as measured at lnb) (lowest I tried) and all worked well.

Knowing that DP works even when the 20+ vdc drops to +12 may even make some longer cable runs fly by using "out of the box" power insertion methods.

A little off topic, but I just remember why I did testing on this.

With the heat related FSS lnb problems. I thought maybe the power dumped by shunt regulators in the lnbs could be contributing to over heating. At least with short cable runs and full voltage available to lnb.
