I have a VU duo+2 and two satellite one prime focus (28.2) and the other Triax TD 110. The problem is when I set the box with a Vu+ Dual tuner 1 works just fine or in tuner 2 works fine but with both set up only one tuner 1 will only work. Could it be the a problem with the Tuner or with the vu duo itself.

Dish 1 both dual lnb 13 and 19 into diseqc 4/1 into diseqc 2/1 line 1
Prime focus 28.2 quad into diseqc 2/1 line 2

Dish 1 both dual lnb 13 and 19 into diseqc 4/1 into diseqc 9/1 line 1
Prime focus 28.2 quad into diseqc 9/1 line 2
Here are some pictures of it.
I did try it with

When you say dual LNB do you mean a 6 degree monoblock LNB, for 13E and 19.2E. or do you mean twin LNB's, with two outputs?
please post more details regarding your dish set up, and make/type of LNB's.

Stupid question: Surely you do not connect the output from the DiSEqC 2/1 switch to both inputs, no?
What goes into input #1, and what goes into input #2? Do you have two DiSEqC 2/1 switches?

ok Sorry just two dishes (one prime focus and the other offset) one has two twin lnb's on it tow lines going to 4/1 diseqc from that going to 2/1 diseqc on line one then 28.2 prime focus with twin lnb going straight to line two on the same 2/1 diseqc. From the 2/1 output going to vu duo 2

Then the same setup going to the line one on the 9/1 diseqc and then the 28.2 prime focus going to line two. the rest of the input lines on the 9/1 diseqc are empty.

the twin diseqc is inverto Black Ultra Twin HGLN Universal LNB, 0.2dBI
Hope that clarifies the setup a bit more.

Thanks
Jason

Thank you for the clarification.
Your set up sounds basic, and no need to use the advanced configuration options.
Go into the menu, Tuner Configuration, select Tuner A, set it to Simple, Diseqc A,B,C,D, and set each port to the satellite using the Diseqc switch,
Once done do the same for Tuner B.
What image do you have loaded?

My Satellite Setup
OpenBox X5 on a 1 meter motorized dish.
And now a 10 foot "C" band dish.

Custom built PC
My Location
Deep in the Boonies in the central Sierra Nevada mountains of California.
I would have use a single multi switch, 4 in 4 out, or......

I would use this switch, it combines all into one with two outputs, less stuff to go wrong.
EMP-Centauri - DiSEqC switch S8/2PCN-W2 (P.167-W)

And be sure all switches are grounded to each other and to a good Earth ground, this will prevent 22 kHz switching cross-talk from the coax jumpers.

So I take it that both your 4/1 switches are 'normal' diseqc 1.0 switches?
And that you have your dishes far apart from each other, and the receiver somewhere inbetween, therefore needing the cascaded switches solution?

The S2/1PCN-W1 is a queer kind of switch. From the manual I deduct that it acts on diseqc 1.0, 1.1 and 1.2 commands; whatever it receives first? Though I'm not 100% sure about that.
You'll have to set the diseqc menu according to that first command needed; in your case best diseqc 1.1.

Does this help:
for 13E and 19E also set diseqc 1.1, to 'input 1' (leaving diseqc 1.0 command as you have it setup already as B and C (I presume thatś correct?))
set command order for all sats to 1.1 - 1.0 - toneburst,
while testing always put fast diseqc to NO,
1.1 repeats and sequence repeats probably NOT necessary
for 28E set diseqc 1.0 command to NONE (or A)


Added:
The 9/1 switch P168-W V2 acts similar; reacts to "highest" diseqc mode for which a command is recognized, if I read the manual correctly. For the use as diseqc 1.1 switch: do as above.
Maybe the VU receiver has the possibility to copy the LNB-settings from tuner to tuner?

Sorry one more thing to clarify both dishes are in opposite sides of my block side 20meters on each side with the vu duo box in the middle that is why I need to cascade the diseqcs. I will be adding two more lnbs to the 4\1 diseqc later on. But the question was why does it works only with tuner A or tuner B with that setup but not both at the same time.
I am using openatv image

Thank you.

Having read your post again, I'm now a little confused.
Where are your Diseqc switches situated?
You could simplify things by running your cables to a distribution centre, like your attic, then a cable from each Diseqc switch to your receiver, eliminating the 2/1 Diseqc switch.
Can you please draw a diagram, scan it into your PC, then upload it, explaining how your cabling is connected, from each LNB to your Diseqc switches.

I guess the answer can be found here (it was what I suspected):

That would mean: diseqc 1.1 switches direcly 'after' the receiver, the four resulting cables running opposite directions (2x2) to both dishes, at one dish two 4/1 switches for (ATM) 2 twin LNB's.

Correct me if I'm wong?

That's correct then two cables going straight to the prime focus twin lnb.

I changed the setup on tuner B on the vu Dou+2 but now I have added more lnbs to the mix.
So 0.8, 4.8, 13, 19 and 28.2. They are all with one diseqc going to the 9/1 diseqc but now I can't get that to work.
That's
Line A on the vu Dou+ 2 is with inline diseqc first to 28.2 on line two and then to the other four lnbs. That one I get
Working with 13,19and 28.2 but nothing on the 0.8 and 4.8. I know they are working because if I set the to simple diseqc I get 0.8, 4.8, 13, 19 with no problem on both tuner A and B.
What am I doing wrong. Please help and thank you.
PS it takes me time to do the adjustments with the system so if I done respond I am just trying what I've been suggested to do. So again thank you all for your help.

Hi Jason/@Jaska-oz,

Do I understand rightly that you got 13-19-28E working correctly, with the suggested diseqc commands?

And that now you are adding 1W and 5E on the 4/1 diseqc 1.0 switch, and have trouble finding the right commands for them?

Then try this:
-for 1W and 5E also set diseqc 1.1, to 'input 1'
-for 1W and 5E set diseqc 1.0 commands at A and D (I don't know which LNB you connected to which switch-port)
All other commands equal as in the other LNB-menus.

Take your time, but please report back your feedback if it works or not.

Greetz,
A33

Hi there,
They started working after I updated the openATV.
So I got the 9/1 diseqc working with all the lnb's so thats great.
But the two diseqc switches inline with tuner A worked for one night with all the lnb's (five satellite lnb's) but then this morning the 0.8 stopped working with that setup. Mystery
I think I might just add another cable and get a second 9/1 diseqc switch, it seems more stable.
Thanks for the help everyone.

Jason

Nice that it is (partly) working. :)
Do you mean that updating openATV did the trick?

With switching problems: try setting sequence repeat to YES instead of No. When a switch is starting up 'slowly' (some switches do), that could help. Setting diseqc 1.1 repeats to ONE would probably have about the same effect, so you could try that on top.

Are you sure there isn't a little contact problem at the cables of 1W? Did you check reception, leaving the switch(es) out?

set it to 1.1 with one repeat and now they all work again. Thanks for your help. I think updating it helped but I guess it could also be a slow switch for the inline switches.

So all working now. Thank you all here for your help.
