Hello, i have two dishes and i'm using a satconn diseqc 2.0 4x1 to switch between them,when i first turn the dm500s on i can't get any channels from the dish on lnb2 but after a while it start to work ok.
What could the problem be the switch or the dreambox.
Thanks.

Try using a different port instead of port 2 and see what happens.

I have found this on some types of switch, was using an "Orbital" switch on a job the other month and initially it wouldn't work on the second port, until the first port had been used. :)

Just tried that and couldn't get it to work at all,i did notice that i could spin the plug so i have nipped it up with a spanner.
If i got a 2x1 do you think the problem would go if the tightend plug doesn't do anything.

Well if you only have two inputs, a 2 way would be better, as it has a lower insertion loss. :)

Thanks for your help.

Still doesn't work.
After a bit of searching it seems that a spaun diseqc switch is recomended to be used with the dm500.
Does anyone know the best place to get one of these.

The 4x1 switch is a Satconn and the 2x1 is a Vialuna ,both cheap off ebay,if i thought it would make that much difference i would have gone for something better in the first place.
The thing is now i don't want to be spending £30 to find it still doesn't do its job.
Do you think if i brought the cable from the other dish indoors and put the switch next to the dreambox it would make a difference.

That shouldn't make any difference and it is always advisable to put the switch within a couple of metres of the dish.

I have to say that I have installed several types of switches and apart from one occasion when a receiver was faulty, I have always managed to get them working with whichever receiver was in use.

Whereabaouts are you?

PS. what are your exact DiseqC settings?

The first dish has 1m of coax and the second dish has 7m of coax from the switch.
I'm in Sheffield.
The box is set for 2 satellites via diseqc a/b ,the 2x1 switch isn't as good as the 4x1 switch,once the 4x1 is working it doesn't seem too bad but the 2x1 looses it most of the time.

What other choices of DiseqC do you have?

I have had another mess around with it and put the 4x1 switch back on,this time i swapped the dishes around and did a rescan ,it seems to be a lot better with just the odd channel not coming on until i change channels.
I will give it a few days and see what happens ,looking round it seems that this is a common problem with dreamboxes and the spaun switches are the only ones that are recomened.

These are the options in the menu.

One satellite
Two satellites via tone burst
Two satellites via 22khz (only highband)
Two satellites via diseqc a/b
Many satellites via diseqc rotor
Non standard user defined configeration

Dreambox dm500s using Gemini 3.4 ,dish one is a zone 2sky dish at 19.2e, dish two is a zone 1sky dish at 28.2e, i get a good signal from both and don't have any other problems other than the switching.

Not sure, as the 22Khz tone is used to change band on the LNB as well, I've never personally used one.

I'll check to see if I have a 2 way global switch and if I do, I'll send it to you to try.

I wasn't too sure myself if it would work, although i do have an option of two satellites via tone burst,i wish i knew what i was doing :-rofl2.

Thanks for the offer of the switch,that will be good,theres one on ebay at the moment but was unsure about spending more just to try it out.
I'm on the verge of ordering the spaun switch ,if that isn't going to work for me nothing will.

I believe your problem is not with the DiSEqC switch, I believe you will need a SW21 switch in addition to your DiSEqC switch as the the SW21 switch is what switches from 1 dish to another dish. The DiSEqC switch switches the signal from Vertical to Horizontal or Linear to Circular. You may want to read into the SW21 switches as it may give you more insight as to what I'm referring to.

Thanks for the input intrepi but i think you are wrong.
Just to update this , i now have a global switch and fitted it but i'm still having the same problems sometimes it switches and then i doesn't.
Reading the instuctions it says don't mount no more than 1m from the lnb ,could this be the answer,anyway if the weather is any good this weekend i'm going to move the dishes side by side and see if it works.
I have also contacted global to see what they think.

Sounds more like a deficiency in the Dreambox, I know they say about mounting distance on the switch instructions, but can't see how that would affect the switching.
