Linking two Receivers on Camper Motorised Dish

davidod1

Hi Folks,

Following information that I gleaned from a long Saorsat topic elsewhere on this forum I am now a little more informed. However I have some further technical questions that I think are more suited to this particular area.

I have a fully automatic motorised dish on my camper. Through the menu system you select either to operate the special elements regarding the dish, or just select the channels for the chosen satellite.

The main controller/receiver (Antarion CS100) is not HD DVB-S2 compatible neither does it have DiSEqC ability. I will need both to receive Saorsat and regular FTA channels. Mind you I would prefer the second one to be a Freesat receiver, but I don't think that would be a runner.

I have written to the manufacturer regarding supplying a new model that would have DiSEqC and DVB-S2 compatibility and they replied that they do not but a suitable receiver could be added to the system and wired through the existing receiver. They attached a drawing - see my attachment. Translation of their instructions is also attached.

My question is simply this. Do any of you highly technical bods out there see it in the same was as Antares seem to see it. Putting it simply they are saying that a new receiver with HD DVB-S2 and DiSEqC can handle the two LNBs - one for Saorsat and one for Astra. The selection of the satellite could still be made using the original unit (the CS 100).

Apologies for the long post but I felt that a full explanation at this time might prevent going around in circles later.

The part in bold is what i would do. Use the original unit to send the motor to 28E or 9E. then get a second box with twin tuners or a diseqc switch to watch both freesat and saorview

Thanks Recyclebin. Looking at the attachments that I put up, have you any idea how to go about linking the two units together though?

The motor controls seem to operate independently of the lnb downlead (unlike DiSEqC).

If that's the case you can simply bypass the existing receiver with the lnb cables.

What size is the dish? It will probably take a bit of ingenuity with regard to where you aim it if you want to receive both satellites with either or both lnbs offset (unless you've got a combined Ku/Ka lnb but they don't exist).

Thank Peter,
The TV can only be connected to one of the receivers but I will need to be able to see the menu options from the original receiver.

On the drawing from Antares they showed a link cut (top left) and presumably a connection made from one receiver to the other at that point. Does this make sense to you?

davidod1

Thanks Peter,

A connection from the TV can only be made to one receiver but it will be necessary to access both the menu on the original receiver and then of course the new receiver.

On the sketch that Antares sent they showed a link that is to be cut (or removed). It looks like the new receiver should be connected at this point. Does this make sense to you?

Peter Rhea

You mean the lnb 'loop out'?

That won't solve the problem of only being able to view the output of 1 receiver on the tv but it would mean you could leave the lnb cable connected to the Antares receiver, should that prove necessary.

I don't know much about these systems, I must do a bit of reading now that it's caught my attention.

And I think it would if the receiver scans for signals while moving the dish . . .

Peter - I have just realised that I did not put up the intended document. I have just attached it here. I'm not sure if it will help or not but have a look at it.

Yes; the receiver does require a signal in order to lock on and fine tune. I would expect that this would need to be a direct link to the dish rather than coming through another receiver.

I don't know but it's looking a bit dicey to me. But yet the manufacturers seem to think that there isn't a problem. Have a look at the new document and see if it clears anything for you.

Thanks Peter for your time.

Peter Rhea

Yeah, you can use the lnb loop-out to connect the 2nd receiver.

Not sure how it would work out in practice wrt the lnb switching commands from the 2nd box.

davidod1

Ok - I think I'll chance getting a Ka LNB and if I can find it; a Freesat box with DiSEqC and DVB-S2 - oh and run off 12v. Although I'll probably have to settle for an FTA box.

When it comes to connecting up the second box I may have to revert back. Hope that's ok.
