DPP44 Without Power Inserter = Overheating 722?

In my new install, I have a Dish1000+ with a DPP44 running one coax (~60 ft) to a single VIP722. I have no other receivers.

I had problems with pixellating channels earlier in the week and when I checked the signal strength, I had 47-50 on the satellites. Sometimes red, sometimes green. On a scale of 125, that seemed low to me.

I called support and the support person asked me to make sure the 'power inserter' was plugged in. I don't have a power inserter and she seemed quite surprised when I told her that. We basically determined that I need a service call.

I went up on the ladder to verify (my switch is mounted on the dish) and sure enough, no power inserter. I also noticed that the dish is pretty loose, it seems that instead of a full length cross bolt on the lower mast anchor, the installer used two small bolts (one on either side) and now it twists pretty easy. So lots of thing for the service guy to fix. :lol:

But that's not my real question.

I've also noticed that my 722 has had that 'new electronics smell' pretty much all week long. I would expect a few days, but not 10 days later. I'm speculating (based on a forum search) that the 722 is itself powering the switch and perhaps overworking the power supply. Anybody have any experience with that? Could that be what I'm smelling? An overworked power supply?

Did you check the other end of the cable? Usually, the inserter is most easily inserted in the cable on the receiver end since it's transformer needs it's own electrical plugin for power and the receiver has one close by.

Thanks for the suggestion. Yes, I did check the receiver end and there's only the splitter/diplexer connection to power both tuners. No transformer on that end either.

I think the installer just gambled that the cable run was short enough that an inserter wasn't needed. It's easy to gamble when it's someone else's money. :nono2:

I don't know about the 722, but when they installed my 612, they said that the 612 provides more than enough power to power the dpp44 and removed the power inserter. I haven't had any problems with the power inserter removed.

I've never heard anyone say officially that the power inserter was ever not required/needed. There are some cases where the ViP series receivers in particular can provide enough power to run the switches, but the receivers were not designed to do this and you're asking for other problems down the road.

As for the signal levels at "40 or 50" seeming low on the 125 scale... Well, Dish changed how they use that scale a while back and I don't think you can get above 100 anymore even with virtually perfect signal. Don't know why they didn't change the scale, but typically I'm in the 70-80 range on 110/119 transponders and 30-50 on 129 transponders.

Glad for me that they just installed two DP34 switches when I upgraded to a ViP612

Wow. Installing the 44 switch on the back of the antenna and no power inserter for one 722? Talk about a pain if it's time to service that switch! No DPP44 can (at least on paper) run without a power inserter. I always install one because it's there in the box and what am I going to do with just a power inserter anyway? The new DPP33 switch does not need a power inserter. Strange about that install, the 1000.+ LNBs actually have 3 DPP outputs and one input, hardly a need for an additional switch. When I install a DPP44, I ALWAYS use DP Duals because every DPP44 with a DPP Twin or even a DP Twin (or quad) will fail due the amount of switches in the system with the internal LNB switches...oh well...

The power supply inside the receivers are NOT designed or rated to provide enough power to run the DPP44 switch, which is why a power inserter is supplied with every new DPP44 switch and is *required* for every DPP44 installation.

The ozone smell means that your 722's power supply is being severely overtaxed by supplying too much power, and will soon burn itself out.

You definitely need a service call.

That's what I kinda' thought....

Thanks everyone for the great info.

We'll see what the service tech does.
Fortunately, I don't think it'll be the same guy.

I have a Vip 622 with the DPP44 switch I was told also that since I only have one receiver it was not needed. Now the thing is I have the power supply. how do I conect it to my system. He left it and told me that if the DPP44 had to be replaced down the road that I would have to send back both to get new ones replaced. My system has been running like this for over a year.

Don't believe it. A dpp44 uses roughly the same power with one receiver as it does with 4. The power inserter should have a wire (it is detachable) that you connect between your satellite and your receiver. Make sure to connect with the power off on the receiver and the power inserter and that correct orientation (one side says to switch, and the other to the receiver satellite input). You probably will connect the receiver satellite input side to your DPP seperator and then the two seperator outputs to your receiver.
