Hi I have just been reading this thread.

The multiswitch you have can do two satellite positions to all receiver and also has terrestrial feed to all receivers. The most I have seen as said is 4 satellite positions and terrestrial but these are very expensive.

You would need to look at earthing. This is VERY important especially as the system is connected to two houses. A fault at one house could cause the other house to CATCH FIRE, hence the regulations. As an installer that has done earthing for apartment wide systems.

Beware the multiswitch is basically splitting the signal over`16 different ways so it is VITAL the dish is large and aligned perfectly.

You need to check the signal BEFORE the multiswitch on firstly a quad then a quattro. You need to make sure each lead of the quattro is giving a good signal. After the multiwsitch it is hard to measure the signal properly as the multiswitch has a booster inside. Depending on the model and what is inside it may always give high signal readings even if nothing is connected.

If you have long runs of Satellite cable you need the best quality cable. It needs to have a solid copper core, solid copper screen and solid copper foil. Anything else will not work well.

As suggested some multiswitches have variable gain and you can vary the output signal at each outlet to compensate for long or short runs.

Ideally you would set every receiver up to get an ideal level, not too much, not too little. Otherwise some channels may not work reliably.

it does look right yes. I can't check for sure at moment though.

If you're checking 28 east, include some of the Eutelsat 28A tps as well, since it is at the 28.5 slot, whereas the Astras are at 28.2 & you might have to compromise a bit on alignment.

Full list of 28 east here. Afaia, all receivers switch the lnb to its 10600 mHz L.O. (high band) for tp frequencies above 11700 mHz.

icsmjd

Ok

Just found out that the lnb was in position 1 for region 1. As we are in region 2 i adjusted it and hey presto, i have signal quality on all bands

I still have no picture on the outputs of the TMP 9x32.
i have noticed some gain adjustments on the switch.
VL VH HL HH gain on each side.

Should i adjust any of these or will it cause damage?

Ronnie Raygun

Afaia, only Sky lnbs have skew marks 1, 2, 3 etc. Are you connecting a Sky quad to the multiswitch?

Someone else asked this already (& I don't mean to insult your intelligence), but is the switch plugged in?

zg3409

Make sure the 28.2 dish is connected to Sat 1 input on the multiswitch and not Sat2
as per the data sheet:
http://www.dastechnology.co.uk/docs/DAS1429_Triax_TMP_9_x_32.pdf

It should work without adjusting the gain. When working it might be worth adjusting them, but first mark them with tip-ex so you can return to defaults.

icsmjd

Yep the switch is powered on, the quattro doesnt have a marking but i turned it the same as the sky dish(approx). It made a difference but i'm not sure why.

icsmjd

hehehehehehehe

how simple it is when ya know what to do. The inputs were in SAT2. I just moved them to SAT1 and Eureka, it works, it works, it works.

Many thanks to everyone for the help, i could'nt have done it without all of you. Now i just have to get the 13 up and going.


The electricial ppl are looking at the earthing issue later today and there is a bar on the switch to connect to.

would it be possibe to connect a 17 x 5 to this switch so that i could have 4 quattro lnbs to this system to give all sats to each output. If so can it be added close to the dish (power there already) and just use the existing 4 cables to the inputs on the 9x 32.

AAAAANNNNNDDDD what lnb rail would i use and do i need to get a bigger dish for Donegal?

oh yeah, i changed the quattro to a sky standard dish and it is working fine. Wifey made me remove the big dish as it was considered an eyesore, huummmm

Good to see it's working now, should have asked earlier which set of inputs you were using.

No. You should learn what the multiswitch does and how it works or you will confuse yourself as the system gets larger.

By the way earthing is more than just earthing the multiswitch:

Scroll down here:
http://www.aberfanaerials.co.uk/commercial.htm

and here:
http://www.digitalsmart.co.uk/small-irs-system-image-29.html

If a multiswitch is feeding separate dwellings, which may be on different mains power supply phases, it is essential to get a qualified electrician to "earth-bond" the multiswitch. He will understand what this means and will know how to do it. Please consult him first, to ensure that the multiswitch is installed reasonably close to a suitable earthing point.

Warning this is not recommended. It will work less well than a normal Sky dish. Normally for such a system a larger than normal dish is recommended, especially when you have cables running from one house to another house.

Why not put the dish on the brother's house. It doesn't matter what his wife says to you!

icsmjd

The longest run is 35meters and in nice weather here at the moment it is fine. when the rain starts and strictly/ xfactor and sky stops working i shall remind her of her choice regarding the dish. I would rather fall out with my wife that the bros. silence is bliss and i would have to listen to him as well as her

i do have an area when i can put the dish. its a little further away from the main house hence the question regarding the 17 x 5. I can put as many lnbs on it as i want

icsmjd

OK

Just setup the 19.2, these are the readings i am getting from each channel

The quality and S/N fall away. I have checked and rechecked the cables and where i am connecting. It makes no sense.

This is the SAT 2 on the 9x32. SAT1 is 28.2 and is working fine on all channels

has anyone seen this before?

mjd

Peter Rhea

How do you know the switch is outputting sat.2? Those tp freqs. are also used at 28 east. The ones with the poor quality figure are DVB-S2 tps.

icsmjd

hmmmm, I don't. is there anything that i need to do to enable SAT2 output on the switch. all the signals are fine on each cable. is there a switch?

mjd

Peter Rhea

The multiswitch will use DiSEqC commands for switching between sat. positions. I don't know if your meter can perform this function or if you'll have to connect to a receiver.

icsmjd

Ok have tried on the reciever, no picture and no signal strenght

mjd

Apogee

Have you setup Diseqc switching in the receiver? Port 1 or A for 28E and Port 2 or B for 19E.

icsmjd

Again, my lack of knowledge is evident. The meter is not capable of switching and the receiver i am using is set for a motorised dish. The samsung tv with the built in sat receiver has picked up both sats no problem.

It has however not picked up any of the french language stations, i have searched for all stations on 19.2 and no french stations have come up. The english ones are fine. Am i missing something again?

mjd

Apogee

In order to confirm that Samsung is switching correctly, can you list some of the channels which did scan in on 19E

snaps

the french language channels are all encrypted on 19 east.

zg3409

You need to read up on how a multiswitch works. The receiver should not be set to a motorised dish.

The receiver needs to be set to a DiSEqC.

Have you the french dish connected to Sat 2? or nothing?

You need to understand the basics of what a multiswitch does. You also need to read up on what a DiSEqC switch does. The multiswitch has a splitter, a switch for polarisation and polarity and a DiSEqC switch all in one.

The receiver needs to tell the multiswitch which satellite, which polarity etc.

icsmjd

The samsung tv seems to pick up more or less the same stations on 19.2 and 28.2. Has anyone experience of the 8000(mark1) series samsung and what changes i need to make to get it to work.

28.2 is connected to SAT1
19.2 is connected to SAT2

Again I don't think you understand how the switch works. The receiver needs to send a special signal to tell the multiswitch to switch from Sat 1 to Sat 2. Otherwise all you are doing is scaning 28.2 twice and so you end up with many of the same channels twice.

The receiver needs to be programmed to send a DiSEqC message to the multiswitch to tell it to switch from Sat 1 to Sat 2. This needs to be done before scanning.

Read the manual for the receiver or post the exact model number here and we can guide you through the process for setting up the receiver correctly.

Not all of them. Arte, TV5 Monde & France 24 are in the clear, maybe a couple more.

You'll get a few more unencrypted on 5W - France 2, 3, 5 and 0, TMC and TV5 Monde are the main ones.

If you want to get the full suite of French subscription free channels then you'll need a Fransat receiver box for 5W or a TNTSat receiver for 19.2E.

Do these receivers have DiSEqC? If not then they won't work with his current setup.

icsmjd what models of receivers do you have? Do any of them have a card slot?

icsmjd

The TVs with built in sat are Samsung UN55D8000 55-Inch 1080p 240 Hz 3D LED HDTV (Silver) [2011 MODEL]

Some of them do (e.g. Aston Simba HD I think) but price-wise they are expensive.

Actually...the Astrell 013130 also support's DiSEqC. and that is one of the cheaper Fransat boxes (it's SD).
