Gibman,

did you try if a Set Top Box can handle your diseqc switch ?

[gibman]

dont have a stb

I succeeded in getting both diseqc's working.. although switching is very flakey.

I've done some very intensive tests using this simple approach.

under "scanning"

use adv. tuning options: check

freq:11804000
symbol rate:27500

I change LNB between (only 1 active at a time) :

#1 : lbl1BB 0.8w thor
#2 : lbl1BA 4.8e sirius 4

my skystar2 has rock solid diseqc swithcing. always had.

skystar2 results on LNB#2 sirius

	2010-12-11 11:19:29.607205 [(17)]: Scan Got 8 from 8 channels

the channels found on the BG1 tuner are channels that are found on LNB1 thor.

If I do a lot of scannings on this TS. It will eventually change LNB.

I tried sending diseqc onbeforetune. no luck.
also multiple diseqc sends will not help.

So the problem all along has been changing the actual diseqc.

each diseqc send request does, as expected, end up calling:
genericbdas.cs --> protected bool SendDiSEqCCommand(ulong ulRange)

all seems ok, code-wise. it just doesnt change lnb.

again, my skystar2 is more than happy with diseqc.

[gibman]

seems like this did the trick:

a bit exaggerated sending the diseqc 10 times.
I'll try and find the sweet spot here. maybe 2 times is enuff.

too bad a device has no way of knowing wether or not a diseqc switch has in fact done the switch.

 public override void OnRunGraph(ScanParameters parameters, DVBBaseChannel channel)
    {
      if (channel is DVBSChannel)
      {
        for (int i = 0; i < 10; i++)
        {
          base.SendDiSEqCSwitchCommand(parameters, channel as DVBSChannel);
        }
      }
    }

Hi again gibman

Your switch is a 4 port switch isn't it. What is connected to the other 2 ports?

1 (AA): ???
2 (AB): ???
3 (BA): 4.8e Sirius 4
4 (BB): 0.8w Thor

How are you connecting your tuners - via a splitter, or changing cable from one tuner to another? If via splitter, does the splitter pass power on all ports?
The default port that a tuner will pick up if DiSEqC is not working is port 1 (AA). I find it difficult to understand how the BGT3595 is picking up Thor (BB) if DiSEqC is not working. Are you using your Skystar to force the switch to port 4 then testing if the BGT3595 can force the switch to port 3? If so, you have to make sure that the Skystar isn't holding the switch on port 4 and that the splitter is passing the BGT3595 commands...

Personally I use an EMP Centauri Profi Line 9x8 multiswitch. The 8 satellite inputs (the other 1 is for an aerial) are grouped like this:

   DiSEqC   Voltage   22kHz
1.   A       13V       Off
2.   A       18V       Off
3.   A       13V       On
4.   A       18V       On
5.   B       13V       Off
6.   B       18V       Off
7.   B       13V       On
8.   B       18V       On

DiSEqC A = Simple A or AA
DiSEqC B = Simple B (or AB I think)

I only use input 2 and input 5 at the moment (not enough cables to the roof ), but I have no problems switching between the inputs on any of the tuners/STBs connected to the multiswitch. That would be 2 tuners (both DVB-S tuners on one of my 2 Pinnacle 7010ix's) plus 1 STB.

This is why I said try repeating the command
Some switches require this

        }
      }
    }

bought some new diseqc's.

sadly the patch is not applyable on current svn.

could u fix it ?

/gibman

 

[mm1352000]

Hi gibman

Yup, it is starting to get tricky to keep it up to date with SVN head. I'll do that this evening when I get home...

 

[gibman]

Those new diseq's seem to fare a lot better than the older ones.

only preliminary testing.. but so far very good results.

running older vers. of ur patch against svn head 26981-

Excellent news!!!

Are you having to do repeats still?
I guess you're using the test section: what is the fail rate like?

 

[gibman]

new drivers it seems..
havent tried em yet.
