Digiality 8/1+1 Diseqc + dm600, Strange problem!

[hobbe1979]

Hi!

I have a Digiality 8/1+1 Diseqc 1.1 & 2.1 switch that refuse to work as it should. I use it together with a Dm600PVR and Gemini 3.60

The problem is that it won’t work if I connect more than 5 to 6 lnb. I doesn’t madder which lnb’s or input. When I connect more lnb’s a low whistling sound from both the box and the switch can be heard and it stops working. This will happens just sometimes when I using 6 lnb’s. so it seem to switch correct as long as I don’t connect to many lnb’s

I been trying both 1.1 and 1.2 on my dreambox but it makes no difference
settings:

INP1= Lnb [0] A/A Uncommitted Input1
INP2= Lnb [1] A/B Uncommitted Input1
INP3= Lnb [2] B/A Uncommitted Input1
INP4= Lnb [3] B/B Uncommitted Input1
INP5= Lnb [4] A/A Uncommitted Input2
INP6= Lnb [5] A/B Uncommitted Input2
INP7= Lnb [6] B/A Uncommitted Input2
INP8= Lnb [7] B/B Uncommitted Input2

..and...

Sequence repeat: checked
Swap Commands: checked
Fast DiSEqC: Tried Both checked and unchecked

It seems like I overload my dreambox when I connect more Lnb’s …
And I have Of course measured my cables….
Anybody else heard this whistling sound?

I haven’t really understood how it is working but:

Technical specifications say’s.
Diseqc: Max loopback 400 mA.
Dreambox: max 500 mA, shortcut protection
Lnb:1 70 mA
Lnb:2-8 110-140 mA

Are all the lnb’s powered all the time or only the one used for the moment ?

Someone that have any useful input to my problem?
Please Help!
