Unicable Settings and Tuning Issues

[GeoffatMM]

Hi,

I am having problems with tuning the receiver with my Gigablue UHD UE 4K using an Inverto unicable LNB (Details in my signature).

Following forum discussions I moved from a single cable setup to a dual cable setup. Before starting, I checked both cables on my smart TV to check they were working properly and they were. The Inverto only has 4 scr so only 4 tuners could be set up as shown here:

Each tuner has been set up as follows:

Once setup and rebooted I checked the signal for each of the four tuners. A and B were fine but nothing shown on C and D, possibly because the tuner was not being called on to show a programme?

I then did four recordings from the main guide which still showed all the channels previously scanned, most I set as immediate from the guide with one timed. They all worked.

However I then noticed that the freesat selections I had done through ABM were not working (can't remember exactly what made me realise it and I have no screenshot). So I tried to update the Freesat settings and got this result:

I noticed it was using tuner B not A (any reason why?). The result was odd because when I checked the signal it was still fine. I have read that the delay on unicable can be an issue and I see that Abu has posted instructions on what to do when the "Tune Failed" messages comes up (and it has on a couple of occasions) but before I mess with that I wanted to get feedback on the results so far.

The results of the scan only gave 260 channels not the 800+ that I had. I then noticed that it was 26 copies of the same ten channels.

When I then looked at the freesat listings, most channels were not there. I tried to rescan again but it once more would not let me:

I do not think it is a signal problem (but it might be). I think the settings are as they should be (but could others check please?). So I am unclear why the scanning is not now working in this new 2 cable setup.

Hope someone can help.

So you are using a splitter on the single unicable output from the LNB to make two connections to this Gigablue UHD UE 4K box?

[GeoffatMM]

Yes BB , that is right.

Take a look at this post from Huevos:

Yes Willo,

This is the post I incorrectly attributed to Abu. It was Huevos. I am not sure that this is the scanning problem. By the time I come to scan the machine should have settled down?

Physical setup:
Remove the splitter. Attach/hook up the signal wire to socket/tuner A.

Software:
Change settings for tuners B-D so that they are all "Connected" to tuner A.

I will update the unicable guide soon.

Thanks Abu,

I have been playing with it unsuccessfully just before reading your post and started by swapping the two cables and that made no difference so went back to the single cable setup and wired direct to the unicable source and it has downloaded a record 870+ programmes. Why? It is a bit frustrating and actually fairly critical at the moment.

I am renovating a house and have gone down the unicable route as I did not want the multiple cables wired all through the house (basically, from the central point to each room requires 5 cables for safety using legacy cables. Unicable seems to overcome this but my confidence is much lower now. I can wire the house so that I can get the main unicable to the receiver whenever necessary but it would be a bit of a pain to do that every time I want to scan.

Is it the quality of the splitter that is the issue or something else (I did ask for guidance on this previously but it was amongst many other issues so got lost in the noise)? Happy to invest im higher quality components if that is what is required.

I suggest we have a different thread for your "scanning" issues. There are different types of scanning. They do things differently and results are based on options you select.

[GeoffatMM]

I thought the whole of this post was about scanning issues but if you feel something should be split out please tell me what, how and where to put the new thread.

[abu baniaz]

Please confirm you have modified the wiring (removed splitter) and modified your tuner configurations.

Tuner setup and scanning are different topics. Please deal with the more important one first.

Hi Abu,

I would like to return to this issue wrt the development of my new home wiring. I thought unicable was meant to deliver the full band of signal to each output by simply splitting it at the splitter or switch. If this is the case, why was it necessary to link the unicable direct to the tuner?

It is important as I had planned to go from the LNB to all rooms on a single cable splitting off at each one as I reach them. For minimum cabling I planned my cabling path as:

:LNB to GTL/ETEL (Obligatory dedicated electrical cupboard for incoming electrical and communication connections for all new homes in France) split to device 1 (VBox):
:GTL/ETEL to kitchen split to device 2 (TV outlet with accompanying RJ45 connection, also obligatory in each room under French regulations):
: Kitchen to Master bedroom split to device 3 (Outlet):
:Master Bedroom to Study split to device 4 (Outlet):
:Study to Bedroom 2 split to device 5 (Outlet):
:Bedroom 2 to Lounge split to devices 6, 7 and 8 (Outlets for smart TV, satellite tuner [2]):
:Lounge to Courtyard split to device 9 (external smart TV for summer):
:Courtyard to Garage/Man-Cave terminating with device 10: (Outlet for ejected husband/testing purposes)

Are you saying that the tuner really needs a direct unicable feed prior to splitting? If so it sort of destroys the concept of unicable doesn't it?

What I do not understand is why the tuner would not work after the splitter (well it worked but only gave 10 channels) but the smart TV worked on the same split cable and brought down all the programmes.

As I asked earlier, is it the quality of the splitter that needs upgrading to enable this daisy chain or series connection layout to work or something else? Or should I be using a centralised, powered multi-switch with a star configuration (i.e., from the central GTL/ETEL to each device with a separate cable?

I appreciate you may not know the answer to all this but perhaps you can point me to someone that does?

[abu baniaz]

You do not need two signal wires to an FBC matrix. Use one wire to the matrix and use the "connected" option.

[GeoffatMM]

Abu et al,

Have done as suggested but as soon as I put the split line back onto the UHD UE 4K it fails.

Then I noticed that although tuner A and B had no signal, C and D did! Still would not tune properly. So the new splitter arrived this afternoon and I changed them over. SCR 1 came back but kept dropping off then coning back. So I removed tuner D and gave scr 4 from tuner D to tuner A and the three remaining scr are working fine.

I now suspect the splitter is fine but the LNB is the problem. The 24 way s due to arrive tonight so will try to fit it tiomorrow and see if that cures the problem. Seem to remember I bought a tuner tester in the dim past so will rifle through my stores to see if I can find it.

[GeoffatMM]

Not sure that conclusion is right either as the cable when connected direct to the receiver worked properly so perhaps even these new splitters are not good enough quality? How can I tell?
Are there any tests I can run on them to check them out?

[GeoffatMM]

Not sure I understand the difference but happy to follow your lead.

Yes unicable in A. B connected to A. C to H FBC Automatic.
