issue with signal

[Isaak]

I just setup 2 t5's, all is well except for one thing... I have to have the receiver on downstairs to have the one upstairs receive a signal.

I have a single LNB with 2 outputs, CNX spitters from each output that go into seperate lines into the house, one upstairs, one downstairs.

I have since deleted one splitter and still have the same issue.

I have nanosat wireless wifi on each but are on seperate IP's.


Anything I am doing wrong? I just don't get it.

simplest solution if your lnb is a legacy type, is to remove the Cnx switches and get one 3x4 switch. That switch will let you connect up to 4 receivers to one lnb with no problems.

[Isaak]

What if I for now... run each line to their own receiver without a switch? dual output single lnb...

I am still trying to wrap my head around how I had it wired years ago, been awhile!

I will be receiving a new dish this week that will be 2 DSS lnb's, so it will be necessary for me to use switches.

I will look into purchasing a 3x4 switch.

Thanks!

Sounds like a power issue. If the receiver upstairs is plugged into a power bar, try plugging it directly into a wall socket.

[Isaak]

I will try that.

But why would it only receive a signal (blue as opposed to red) if the one downstairs is turned on? Just seem's really odd.

[dishuser]

do you have it grounded?

If this is a legacy LNB then you can't split the outputs.

On a legacy system the two outputs are for the transponders, 13 volts at one input gets you the V or R transponders 18 volts at the other gets you the H or L transponders.

Trying to run 2 recivers off the one LNB wont work, as Riverman said use a switch go go between the receivers.

A 3x4 with let you connect the two receivers to the one LNB.

But you said you have a new dish on the way with 2 LNB's on it, you will then need a switch that will work with the new LNB's, what brand are they and who made them?

This is important because if you get the wrong switch you will have switching problems.

If they are the DP type (Dish or Bell) then the switch has to be able to handle the DP type LNB's, (any switch that is Dish or Bell rated, usually DP type) if they are the new type standard LNB's then you will need a standard 3x4 switch.

In either case the two receivers will need their own feeds from the switch.

[Isaak]

It is a dishpro type LNB

Is what grounded? splitters? no.

The new dish is a 18" kit I bought from LEESAT, comes with 2 DSS lnb's.

I will purchase a 3x4 switch to make all of this easier... what brand is recommended? I am in Ontario so I would be purchasing from LEESAT or Research Electronics as they are local to me.

Thanks guys!

Splitters will not work with DP type LNB's.

Any 3x4 switch will work with standard DSS LNB's, Spaun comes to mind.

For 2 or more receivers the 3x4 switch will have 6 LNB inputs, and 4 reciver outputs, it may also have a power inserter.

In your new setup the 2 LNB's will connect to the SAT 1 A&B and SAT2 A&B inputs, or they could be labled SAT1 +13 and SAT1 +18, SAT2 +13 and SAT2 +18, you don't need to connect the other sat inputs. (SAT3)

If the switch needs to use a DC power inserter (some do some don't) it will go on the first receiver coax, now some FTA recivers do not like to work too good with the DC power inserter in-line with them, so a separate coax must be used run to the #1 receiver port, the other 3 receiver ports will run the FTA receivers just fine.

This one from research electronics (your local supplier) will also work great, EMP-Centauri 2 SAT / 4 REC Switch (E-140A) it would be the better choice.

[Isaak]

Thats awesome, it makes sense to me now.

Both suppliers sell similar 3x4 switches, the other being a dish network type.

I just purchased that E-140A.....

Thanks so much! I owe you.

[Isaak]

I just received the EMP-Centauri 5x4 switch.

So your saying, I may or may not need to run a line from the DC to the receiver? Where on the receiver would I plug it in?

The multiswitch is labeled High Band and Low Band... LNC A being a 13V and LNC B being a 18V, same for the other side but it is labeled Low Band.

This has me confused, what is the difference?

I have a setup where I ran one line from each output on the lnb to a receiver and it works fine. No switches involved. when you say its not receiving a signal, does that mean the screen is just blank or does it say no signal or does it say scrambled channel??

[Isaak]

The receiver would not receive a signal from the lnb.

Some new issues...

Downstairs receiver is getting 97% signal on 91, upstairs is getting 78(ish), on the switch does it matter how I wire the lnb's?

If it matters, they are "circular lnbf Royal+ N18K brands, I bought the dish and lnb's from LEESAT, the 18" kit. (DSS lnb's they are called on the site).

Also, does it matter what lnb I place in the dish bracket? I am trying to get 82/91 but cannot for the life of me wrap my head around why it would get 91 signal great but cannot get 82, I obviously am doing something incorrectly. I have 91 lnb in the bracket and the 82 not, it is in a 119/110 bracket.

I am assuming you are using the new multi-switch. You have to match the passive and the active ports on the lnb with the switch ports. In your case you should have 4 cables coming into your switch from the lnbs. the first two ports to lnb1 and next two to lnb2. Within the two ports, one port is the 13 and the other is the 18 with the 18 being the active. You also have to match the proper ports in the receiver/dish setup just as you if you were using a disecq. Have a look in the dish/switch setup section and you will find some drawings that can better show you what I am trying to say.

[Isaak]

I have the emp-centauri e-140a multiswitch.

2 LNB's, one to 82 and the other to 91... but am still trying to figure that out, but I will do that another time.

The multi-switch is labeled LNC A (13v) LNC B (18V) LNC C (18V) LNC D (13V)

Then it has 4 outs (receivers, I only have 2)

I will take a look at the schematics on this site to see what I am doing wrong.

I know the issue I am having has something to do with my setup, pretty obvious... just have to figure it out! the whole 13v and 18v thing has me mixed up.
Thanks for your help thus far!

Did you run 4 cables from the lnb to the switch?? thats a must for the dual lnb. who made the cables?? most lnb I have seen have the first port as the passive and the right port as the active(18v) In your case you have to reverse the cables for your port 3 and 4 in order to get the active port on the second lnb to match your multi-switch.

[Isaak]

2 lnb's, yes 4 cables.

Cables I bought from princess auto, I was there, seen them, and they were the only ones to sell 3 foot lengths I could find locally.

Are the lnb's labeled? I think I remember seeing a 1 and 2.

I do believe I have to take them off anyway because if I am to get both 91 and 82, then I must put the 91 (left) on the arm, and then the 82 on the right side of that so then the signal is bounced off the dish properly (when looking at the dish from behind)

I am going to go back out and redo it all shortly.

Let us know when you have finished re-running the cables. Did you say 3ft cables?? Where is dish mounted?? The switch is not exposed to the environment is it?? Is it powered?? If not, your receiver has to supply all the power as well.

[Isaak]

I reran all the wires to the way it should be, following the 18v and 13v schematic.

These are 4 ft cables I think, nothing special.

Dish is mounted on side of house about 8 feet up in air. Currently pointed at 91.

Switch is exposed to environment and no it is not powered, I have been thinking about that but have read that sometimes it is necessary, others it is not... had me confused. Also I would have to find a way to route that wire to the inside as I only have 2 coaxial cables running inside, one to upstairs, one to downstairs.

I had the one downstairs good, all I had to do was turn on 22hz and everything was fine, but I went upstairs and signal was red, no matter what I tried, didn't work.

Should I have gotten 2 of EMP's because I am only using one Sat, but 2 LNB's (bracket) ? Probably one of the reasons why I am having these issues...
