Unicable Motorised dish

[Johev]

Dear all,

I come here with a question regarding a motor for a unicable LNB. I will be buying unicable inverto black quad LNB. The setup means that one cable will go from the LNB to the motor and only then from the motor to the receiver.

Will any motor do as long as it«s disecq 1.2 or will I have to find a special unicable enabled one?

Many thanks.

For the motor the Unicable protocol makes no difference.
Make sure the motor supports 'Go To' (as most will do nowadays) so you can use USALS.

Thanks Rob,

I have ordered the Jaeger Moteck SG-2500A DiSEqC Motor which is DiSEqC 1.2/1.3 and states that has GoTo X, Goto 0 and USALS.

Do you think it will do the trick or do you have any feedback about this particular model / brand?

Many thanks.

[Rob van der Does]

I'm pretty sure you'll be fine.
But feel free to inform us when setup.

Help Rob, trying to configure the motorised dish but I am not bale to input any value in goto menu of the vix 29/9 image.

Any help please?

[Rob van der Does]

Hmm, just checked here: I can give in numbers in the GoTo line in positioner setup (ViX build 748).

BTW: why do you need that line? tbh: I never used it.
Have you configured the tuner to USALS?

[Johev]

We have configured the 0.8W to position the dish but when we select 0.8w in the channels the box is positioning the motor at 8 degrees.

We have also positioned it manually in the motor (using the buttons on it), we get good signal but after we change channel the receiver moves the motor to 8 degrees instead of staying at 0.8.

[Johev]

would you be willing to help me by phone? sorry but its complicated to explain easily. many thanks (let me know if that would be possible).

[Rob van der Does]

We have configured the 0.8W to position the dish but when we select 0.8w in the channels the box is positioning the motor at 8 degrees.

How do you know that?

We have also positioned it manually in the motor (using the buttons on it), we get good signal but after we change channel the receiver moves the motor to 8 degrees instead of staying at 0.8.

Well, that's intended behaviour. If the dish is indeed a few degrees out, you can correct your own position accordingly (still assuming you use USALS....).
If you have to move the dish westerly to get a good signal, you should move your own position easterly to compensate.
Do this in small steps: it's an iterative process.

[Johev]

The dish is 5 degrees West of, because we configured it manually like that. When we go to 30W it goes to 35W and gets very strong signal, when we ask it to go to 0.8E he goes to 4W and gets strong signal (due to the 5 degree deviation), but when we ask it to go to 23E the dish positions exactly at 23E and missed the satellite by the 5 degrees.

No clue what to do.

[Rob van der Does]

I now ask you for the third time if you use USALS?

[Johev]

Yes we use USALS, sorry and we updated to 5/10 version of vix

[davewhitaker]

Sounds like you may not have the correct long/latitude west/east entered into usals

After this I'd select a 0.8w channel let the dish align by itself then fine tune the mast pole west/east until you get a signal.

Make shore you mast pole is perfectly vertical. Then fine tune your dish angle.

Then check and fine tune everything again. Pole dish lmb

I presume when you put it all together you put the motor at the right angle for your latitude.

Then all you other sats should align automatically with usals

[Johev]

First thank you all for the help.

@Rob van der Does, sorry for the above request. After 18h of fine tuning and messing with everything we've finally given up. The strange thing is that we already installed 4 rotation satellite dishes in the past 4 months (solo2, vu duo (original), Xtrend 9200 and a gigablue), and all went fine, so we have some experience with this setup, but well today was not our day.

Components that we've used:
1) 80cm Aluminium dish
2) Inverto black unicable LNB (we only used the single cable output just for the configuration), we were going to use the unicable output as soon as everything would be working with the normal output but that never happened.
3) Vu+ Duo2 (opne vix 05/10 version), we've also tried a factory reset just to be sure it was not software (as much as we could, only using a different box would rule out 100% software bug)
4) Jaeger SG-2500A dish motor


We could get either 28,5E and 30W or 30w and 0,8W, we could never get all 3 dishes. After much thinking, we believe something is wrong with the motor. It moves correctly to 0.8W and 30W, but every time we choose 28.5E it is 5 to 7 degrees of. If we correct the change manually we get no signal in the other satellites.

No clue why. We have tried to reset the motor (put at 0 and use the reset button), it is by the way a SG-2500A Jaeger (ordered form Amazon.de), maybe something happened during the shipping, no clue.

We have it now setup on a fixed position and the dish is pointed at the 30w, and it is working (but I am not requesting the motor to move, as it would easily mess everything).

Any ideas would be greatly appreciated.

@davewhitaker

Thanks for the idea, but the long/latitude west/east is entered correctly. I went to dishpointer and got the precise coordinates aiming directly form the wall we mounted it on.

It moves to the right direction, but sometimes it just decides to move another 5 degrees more at some satellites, something we could not figure out.


Option 1:

The motor is not well.

Option 2:

VU+ Duo2 is sending confusing commands to the motor. Not sure how, but maybe something needs to be done.

Option 3:

The LNB has a problem, but so far at single cable output it is giving me 80% signal strength and its not even completely fine tuned (just manually aimed).

Option 4:

Something is wrong with the Aluminium 80 cm dish. Not sure what but its the last piece of the puzzle.

By the way the mounting tube is at a 90 degrees angel, we took great care to have it mounted properly.

I appreciate anyone help and ideas. Please keep them coming

[Rob van der Does]

Naah, don't give up.

1- What is your tuner configuration?
2- Is the pole to which the dish is connected 100% vertical?
3- How did you align the dish?
