Enabled FBC tuners for first time.

[gws]

Not sure if this is gigablue or vix 6.9.03. I ordered a unicable lnb from WOS , a gt s2dcss24. First mistake was to run 2 cables to the tuners, learnt you only need one, after this tuners working . 1st problem it takes approx 5 seconds for a program to show on the telly when I switch on, used to be instantly? 2nd issue when the AutoBouquetsMaker runs it now blanks the screen while the ABM runs and when it finishes the program returns as normal. As I have never used FBC tuners before is this normal or is there some settings that need to be changed when you use FBC? Thanks.

I assume that you have mapped the 8 tuners to different frequencies? Tuners B —-> H should be mapped to tuner A

 

[gws]

@ twol I have mapped the tuners as you have stated. I do wonder if it is a power issue to the LNB?

The reason you get a blank screen when ABM runs is that ABM is coded to use an independent tuner.

Easiest way around this is to set the preferred tuner to any other tuner, that way the root tuner won't be occupied.

Alternatively, you could use a splitter. That way A and B have independent signal.

Thank you for the advice and info. When I first set this up I had 2 wires connected 1 for tuner A and one for tuner B via a splitter and could not receive any signal ,signal strength meter and AGC just showed zero, removed cable from tuner B and it all worked? Is there anything special that has to be done to use 2 wires? I have just tested using c as preferred tuner it made no difference.
Addendum; I forgot to restart gui when I tested the ABM fix, now done it and the screen does not go blank when ABM works. Thanks abu for a good tip.

Which receiver? Some receivers require a power injector.

 

[gws]

@Huevos The receiver is a Gigablue UHD Quad 4k pro.

Let's wait for twol to reply, he has one set up with unicable... but I think you need a power injector to avoid the long pause.

Initially I had Quattro LNB's into a switch that output as Unicable and legacy and that worked fine, but as I then moved boxes into different areas and moved everything to Unicable I ran into issues.

2 unicable LNB's (19.2E/28.2E, different brands) running to about 8 boxes including 2 Pro's.
My boxes are separated between different areas so there can be quite a cable run between LNB's and 1st splitter and then onto next splitter.
I would find issues that some boxes would take ages to pick up the signal from the Unicable LNB (legacy no issue) or some boxes not at all with the standard power up delays - especially on the longest runs..

Bottom line is that 1) I have installed power inserters (Inverto ) on both (and have updated tuner configs to say externally powered), so 1st connection is the power inserter (3 connections, input from LNB, power connection, output to 1st splitter)
and 2) I use a branded 1st splitter (1 in 6 out) - (over time I have a collection of splitters that I have tried and once you go over 1 in 2 out, there can be issues) but this one(Edision) seems to work well.
I then use 1 in 2 or 3 out elsewhere.

So Yes, I think power inserters are a good idea. Otherwise keep the setup as simple as possible.
It also helps that I live in a country & area where every house has a sat dish regardless so these components are still available.

 

[gws]

Thank you all for your replies. I shall investigate power inserters .

 

[Huevos]

"updated tuner configs to say externally powered"... where is that setting... I can't find it.

Edit: hidden for me...

                    if not SystemInfo["FbcTunerPowerAlwaysOn"] or not self.nim.isFBCTuner():
                        self.list.append(self.externallyPowered)
