Help setting up Unicable II setup requested

30 June 2024 - 12:52

Hello all,

hopefully someone is able to offer me some help setting up a Unicable II solution. Any help will be greatly appreciated.

The goal is as follows.
 
I have number existing satellite receivers, one is VU+ Duo4K (first edition) and the others are VU+ Zero4K
 
Currently I have a setup using 2 Optical LNBs that are connected via 2 Optical to Coax converters. The output of these optical converters are 2 sets of VL / VH / HL / HH coax outputs that are fed into a SAB SMS 9/8 S Multiswitch.
 
LNB one is used to receive Canal Digitaal via the 23.5E Satellite position. 
LNB two is used to receive UK FTA channels via the 28.2E Satellite position. 
 
I'd like to upgrade this setup to a Unicable II setup where the VU+ Duo4K will be able to to use all virtual FBC tuners using a single Coax cable and while being able to receive 8 transponders at the same time through both satellite positions 23.5 and 28.2.
I'd like to keep using the optical LNBs and optical to coax converters I have installed. I would assume that an optical LNB + converter would have the same result as a "normal" quattro LNB.
 
Through some online research I found that it should be an option to replace the current SAB multiswitch with two Inverto Unicable switches (2x Inverto IDLU-UWT110-CUO1O-32P). One switch per LNB and feed the two Unicable outputs from the two switches into a combiner (Inverto IDLU-UCM1O1-OOO2O-OPP). From the combiner a single cable could be connected to the coax cable that currently feeds the VU+ Duo4K and if I understand correctly the Unicable signal should allow to provide the 8 FBC tuners 8 transponders across the 2 satellite positions.
 
I'm following this setup as provided by Inverto: https://inverto.tv/u...-1502440753.png
Be it I don't use 4 wideband LNBs, but 2 quattro LNBs instead.
 
So I ordered the 2 Inverto Switches + Combiner and hooked it up like this:

After connecting the swithces and the combiner I cannot seem to get both satellite positions working at the same time.
 
If I connect VL-VH-HL-HH for the LNB pointed to 23.5E to multishwich 1 -> add the power inserter -> connect to the Combiner port 1, I can receive a signal successfully.
 
If I connect VL-VH-HL-HH for the LNB pointed to 28.2E to multishwich 2 -> add the power inserter -> connect to the Combiner port 2, I can receive a signal successfully as well, but only if I disconnect 23.5 from combiner port 1. If I connect both multiswitches at the same time to the combiner, neither will return any signal and I cannot watch any channel.

So both positions work independently, but just not if connect both at the same time.

Surely I’m overlooking something obvious and maybe someone could point me to the correct direction. How should the tuner be configured in OpenPli so that the receiver and switches will know which channel is for what satellite position? 

These are the Tuner settings I set up:

LNB1 for 23.5

LNB2 for 28.2
Attached File  Tuner_A_LNB2.jpg   80.72KB   0 downloads

But this doesn't allow receiving both positions at the same time. These settings work fine if I connect only one of the cables feeding the switch into the combiner. however as soon as I connect both no signal on either satellite
 
Note I have also tried setting the Userband to other channels for each LNB, but same result, no signal when both are connected, only if I disconnect one and leave the other will I receive a signal.
Also if I change the setup for positions; so I tried changing the settings for 23.5E by changing LNB1 + Position 1 into setting LNB2 + Position 2, and if I vice versa, I tried changing the setting for position 28.2E from LNB2 + Position 2 to LNB1 + Position 1, the same issue.

Any idea what ' doing wrong? Will I need to use a programmer to setup the 2 switches to be tuned to a specific satellite position? And if so can this be done using SP-IDLU-SPAL03-OOOBT-OPP ?
Or is the setup as I intend possible using the default settings for the Inverto Switches?

Hopefully someone can help me figure this out.

Thanks!
