Signal levels are adapted based on what the user has subscribed to and what the cabinet serves.
If there are lots of devices subscribed to the cabinet with splitters galore, they increase power levels.
Upside: People far from cabinet get better signal. But could need forward path attenuators
Downside: People near cabinet have too much signal and need attenuators.
It is a process of elimination of the varying factors/components in the setup.
I shall post the a general guide of order in which to do things and you can decide what you want to do/want to reject.
1.
Connect signal wire to correct port. Some Cable/Hybrid tuners have F-plug connectors, others have Belling Lee connectors. You may/may not need to use an adapter.
It has been known for people to connect the DVB-C signal wire to LNB input terminal of receiver. It has also been known for people to connect to the RF out connection.
Most twin tuner moudules have a single connection, the signal is split internally. Some people get confused by this and start wondering as it is a twin tuner, where does the second signal wire go? Don't worry about it. Just connect to the "RF input".
2.
If using PLI, it does not have a cables.xml. Source one and transfer it to /etc/tuxbox and then reboot receiver.
If there is no cables.xml, you won't get a provider option.
3.
In Tuner configuration, set to the following
Tuner Type = DVB-C
Configuration mode = enabled
Network ID = leave it as 00000. In the UK you can use any value, makes no difference. If you want to put in your net ID, go ahead.
Used service scan type = provider.
Country (If on your image) = Quicker to scroll left for the UK
Region. There are four UK Virgin options. Pure, ex-CW, Telewest and Bruteforce. If you know which system you are in, select it. If you don't know, select Brute force.
Do this forall tuners.
Scanning/plugins
Before we go any further, please be aware there are essentially only 5 free channels. Just because it is free on satellite, it does not mean it is free on cable.
BBC1, BBC2, ITV1, Channel 4 and Channel 5.
Please be aware that unless you are in a pure area, you will get channels that do not work in your area.
You can scan using the scanner in enigma2 and then make your bouquets or you can use plugins.
Enigma2 scanning
Menu > Setup > Service Searching (Tuner Config) > Manual Scan
Select the correct tuner
Type of scan: Change to Complete
Press OK/Green to scan
There are three plugins available that will work on cable:
AutoBouquetsMaker (ABM)
AutoBouquets Cable. (AB C2)
CableScan (Pointless using this but PLI love it, handy if you don't have an xml)
To avoid confusion please don't just say AutoBouquets as the plugins work differently.
ABM:
ABM does several providers and it does not need a scan first. So this may be your better option.
Install ABM if it is not already included. It is available on the plugin feeds under system plugins or available on forums
Menu > Setup > Service Searching (Tuner Config) > AutoBouquestMaker
Go to provider, Enable Virgin UK. Select your Net ID. Only headends are listed, number is the important thing. If you don't know it, pick one nearest to you.
Press OK to save
Highlight scan and press OK/press Green to scan.
If you have used he correct Net ID and adequate signal, the free channels in the Entertainment bouquet will work. There are no free HD channels on Virgin!
AutoBouquets Cable
When using this plugin, you must be on a cable channel.
Highlight your area and then scan. Pure areas have been bundled in one list.
Problems fault finding
If there is a problem, you will have to rule out the possibilities. Change one thing at a time.
Below is a list of possibilities:
No signal to property. (If you don't have any VM services, VM will disconnect the supply to your house)
Faulty isolator
Faulty splitter. Just because one port works, does not mean others are fine.
Faulty signal wire
Faulty F-plug to belling lee adapter
Faulty tuner
Faulty receiver
Too much signal (use an attenuator to compensate)
Too little signal (use a variable powered splitter to overcome issue. You may need a forward path attenuator too.)
It is important to note that different tuners have different sensitivities. Just because one worked, it does not mean all will.
The signal level readings on the receivers mean very little. Different brands/models will report back different values.
Don't forget to factor in "user error". It is only natural to think we are doing the correct thing. When posting, be descriptive as possible. You can see what you have, but others are not there. When people offer advice/ask questions, it is in your interest to answer the question. If you do something different say so rather than pretend you are following advice given but doing something different. Remember, they are trying to help you. Sometimes, people ask for photos because we all make mistakes. A second pair of eyes helps rule out mistakes.
