3900 receiver

[gml9858]

I hooked up a 3900 receiver to a dish 500 dish and the check switch results would only see the odd transponders and no evens. It also sees the switch as a switch 64. I then took another dpp lnb from my other setup and the receiver still saw the switch as a 64 but picked up all transponders. The funny thing is, is that I took the dpp lnb that only picked up the odds on the 3900 and put it in place of the second lnb I used from the other setup which incidently uses a 625 receiver, and it worked fine over there. What's up.

Do you have a DPP Twin? If so, there's must be a DP receiver connected to the lnb to make a legacy receiver work.

Legacy receivers see the DPP Twin as a SW64.

Are the newer generation dpp twin lnbs now compatible because I have a somewhat newer one that works and an older one that does not work with the legacy receiver but will with everything else so I know the lnb is good.

Like I said, a DPP Twin needs to have a DP receiver to make a Legacy receiver work. If you have a DP Twin, it will not work with a Legacy receiver unless you get a DP Adapter.

Like I said, I have 1 that works with the legacy receiver and one that does not work with the legacy receiver.

 

[RandallA]

Ok, do you have any other receiver connected with the one that works with the legacy receiver?

No That is why I can't figure this out

It's funny you mention that scenario. A few years back, when DPP Twins 1st came out, I accidentally did the same thing by connecting a Legacy receiver to a DPP Twin. In the short term, it DID work...but eventually the receiver stopped working. As Randall already stated, in order for it to PROPERLY work, you will need either (a) a DP style receiver connected or (b) a DP adapter. The Legacy receivers just don't have enough juice to sustain operation for the long haul; at least by themselves.

That's what I was thinking webby, it might work but it will eventually begin to have problems.

Look at this post from another installer, he says that it's worked for him and no TC, yet:

So, he split load between TWO legacy receiver; sort of risky setup - in case if one receiver will be disconnected for ( how long ?) say day, other one will be dead and first soon too when it will be reconnected.

The ONLY problem with the scenario in that link is the fact he was using 2 Legacy receivers and not just one. I don't see it working as a long-term solution with just one receiver
