DPP44 and SW44 or DP34

[Jerasa]

Hello all,
I have the attached setup and want to add two more units, a total of 4 receivers. In addition to the setup, I have the shown equipment, I found out that the SW44 will not work with the DPP LNB's and switch but thinking of a DP34? please help if you have a similar "working" setup or have tried it before...
Thanks all...

Remove your diseqc switch from 91 & 82 and replace it with a 4x4, this gives you 4 outputs from the DPP44 and 4 outputs from the 4x4, then use a SW21 for each receiver to combine the feeds from those 2 switches.

yep, replace diseqc with sw44 would work just fine

4x4 and DPP44 need power inserters, can the SW21 pass power to the switches?
What would the receiver settings be? diseqc and legacy switches? I did what you mentioned but there is no signal at the receiver

a 4x4 does not require a power inserter

Your trying to combine two different technology's* into one, it's very very very hard to get this to work right.

(*Dish DP technology and Standard LNB technology, two conflicting systems)

Your also trying to run 6 satellites into 2 or more receivers, this also brings up some headaches.

It's best to use all one type of LNB, less stuff to go wrong, the problems with useing Dish DP type LNB's and switches it the fact that they were never designed to run more then 4 LNB's at a time, to do a 5 or more setup you would need a Diseqc 1.1 or 2.0 compatible switch and receivers, this would get you up to 8 to 16 satellites (single LNB's, one per satellite)

EMP has switches that can take 16 LNB's and run 32 or more receivers, and they are internally powered, (AC power) you just have to get the right LNB's and switch to make it all work without major headaches, however some of their stuff is for legacy switching type LNB's, this requires 2 outputs per LNB to run the system right.

So to do this the right way, all LNB's have to be changed out and a new switch is needed, 6 legacy LNB's equals 12 outputs, you would need one of their 13 x 4 switches. (one input is for an external TV antenna, not needed)


Remember the more stuff you add to the system, the more insertion loss to the system, and the more that can go wrong with the system.

Keeping it simple and with the less stuff to go wrong is the best bet.

It could be done by adding a new DPP44 switch and adding 4-22 KHz switches but you going to add more stuff to the system, and add more problems.

That is a legacy 2x4 switch, 2 inputs from 2 legacy LNB's, +13 and +18 from one LNB (22 KHz off, H and V switching), and +13 and +18 from another (22 KHz on, H and V switching).


And to run 4 standard or DP type LNB's the switch needs an external or internal power supply, some single LNB's need up to 200 mA of DC current to run right, not very many FTA receivers can do this, most can only supply 500 mA.

You see a 4 x 4 switch will run all 4 LNB's at the same time, this adds up in the power drain to the receiver if the switch is not externally powered, if the LNB's used only draw 100 mA then it's OK, but some draw a lot more, this could be why some receivers are running hot, too big a load on the power supply by running too many LNB's at once.

The 4x4 needs no power, you connect both ports on the 82 LNB to one side of the 4X4, and both ports on the 91 LNB to the other side of the 4X4, so 4 cables connected to the 4x4 from the LNB's in total. Now depending on how you connect it your settings will look something like this....

91 - SW21 Dish1 - 22kHZ ON
82 - SW21 Dish1 - 22kHZ OFF
Then your DN sats will all be on the (SW21 Dish2) side, with the proper diseqc settings for each sat.

The SW21 will have to go inbetween your receiver and your power inserter for the DPP44, but it should be said that connecting a receiver on the same line as a power inserter could damage your receiver over time.

The switch posted in the picture by BanHammer is not true 4x4 but a 2 legacy LNB input to 4 receivers output, the #1 receiver powers the LNB's on the +13 or +18 volts for switching between the transponder polarities from the satellites.

On a true 4x4 switch using standard single output LNB's or DP type LNB's you would need an external DC source to run the 4 LNB's at once if the combined DC current for all the attached LNB's exceeds 450 mA. (you need about 50 mA to run the switch)

It's all about the DC current load, if the switch is not an externally power one you may run out of juice to do the switching right.

There may be a true 4x4 un-powerd Diseqc switch out there but most are getting the SAT1 A/B SAT2 A/B type and have problems when trying to combine them with a DP LNB and switch system, they just don't like each other.

Thanks Guys for all your help
will this one work? it says directtv but I only have Bev and DN

That one will work for 2 (two) legacy LNB's to 4 receivers, give it a try.

And please next time no live outside links, make them dead like I did to the one you posted.

[Jerasa]

Will try it
Thanks and sorry for the link

[Jerasa]

All done and works perfectly... thanks all
