For anyone that does need an injection power supply they are going to be available from WoS.

I sorted mine out anyway, i bought a VU+ ultimo, as gigablue don't seem to think there's a problem, bit disappointed with there attitude, i won't buy another gigablue.

Did you log the issue with Gigablue?? Their support forum is in German, but Google translate does a good enough job.Originally Posted by scouse645
yes i did do that, they answered me telling me to try Teamblue image, i had already tried that but no good, on the gigablue german forum there are post's about this problem, they sound as frustrated as me with there lack of help, they never answered anymore emails.
Of course it won't make any difference, it is a driver issue.
I've been testing the GT-Sat power inserter with Gigablue UHD Quad 4K and different configurations on the VU+ Ultimo 4k.
Cures power issues for the Gigablue models and also stops many tune failed message on the VU+ Ultimo 4K depending on the setup you have.
In my honest opinion no receiver works spot on with a Unicable LNB unless its powered 24/7. Being powered also saves waiting 2-3 seconds for the first boot.
I'd recommend the Power injector all day long when using a Unicable LNB no matter what receiver you have: https://www.world-of-satellite.co.uk...power-inserter

There is an option for "externally powered". I have not checked the output voltage from tuner with this enabled though. However, it should not be an issue because you could have multiple receivers connected to an LNB.
The output voltage is controlled by drivers. The "externally powered" is just so Unicable power up delay can be ignored.
@Sicillian, do you know if that inserter block lets voltage through from the STB. e.g. if you remove the power source from the inserter does the VU+ FBC tuner "A" still work?

So how are drivers told not to power LNB?
Independent power going to uplead of Unicable LNB.
Only tuner controlled dual voltage wigglies to Legacy.
The tuner setup asks if there is an external power source. I assume the answer instructs tuner what to do.
That just tells it to ignore the wake up time. ( just learnt that)
Not sure what you mean. Sending voltage up the co-ax line from the STB will happen regardless of the "externally powered" setting. This can be confirmed with a multimeter.
I was asking how to tell the receiver not to send voltage to the LNB when power from receiver is not needed.
Also, if you are using a power pass splitter it should be diode protected so voltage from one STB cannot arrive at the aerial socket of another that shares the same LNB. i.e. the voltage can only flow from the STB to the LNB but not in the opposite direction... and the STB itself should also have diode protection at the socket to prevent external voltage from entering it.
1) As far as I know you can't... so if your LNB is powered over a shared co-ax line the device supplying the highest voltage will be the one that powers the LNB. This is due to the diode protection, i.e. if the voltage is greater outside the the STB than supplied by the STB there will be a negative voltage at the protection diode and therefore no forward current from the STB.
2) If you want to be certain the STB is not supplying current to the LNB use a DC blocker. https://www.tdtprofesional.com/es/bl...oaApzVEALw_wcB
3) A wall plate for a community Unicable install would/should have a DC blocker built in.
