DiSEqC trouble with TT S-1500

Hi,

I've got a Technotrend S-1500 (if it matters: I use it with Kaffeine 0.8.3). It works mostly fine, but there's a strange problem. With my Spaun 4/1 DiSEqC switch (they cost approx 25-40 euro), I can only switch without trouble to position 1 and 2. If I tune directly to position 3 it won't lock.

However, if I first tune to a channel on position 1 or 2 and try a channel on position 3 after that, it will work. Position 4 however is completely unreachable.

On a standalone receiver, there's no trouble with the same cable.

Now Spaun is a really expensive and respected brand. So their switches possibly work in a different way, because a cheap Maximum 4/1 switch works perfectly with the S-1500. Position 1, 2, 3 and 4 all work perfectly. I also did some "dry testing" indoors and it looks like a 7 euro Satconn 4/1 switch would also work fine, but a 17 euro Axing SPU 41-02 probably won't.

I'm guessing this could be solved in stv0299.c but I'm not much of an expert. I took a look at the code but I'm not really sure what to do.

Hi,

Can you explain how you select those 4 positions ? DiSEqC commands or tone/voltage changes ?
Also can you determine the input type of those positions (Hi/Low, H/V, etc) ? A scenario to see when and why that happens, would be more useful.

I select them with Kaffeine. Hi/low and H/V doesn't matter. I tried upgrading to Kaffeine 0.8.5 but that doesn't make a difference. The "scan" application has the same issues.

Nobody any ideas? If not, does anybody have some idea what the difference between position 1+2, pos 3 and pos 4 could be? I was thinking 1 and 2 might be working because of toneburst, but I don't think Kaffeine uses such a signal and that doesn't explain why pos 3 works if first tuning to 1 or 2 and 4 doesn't work at all.

I'll also ask people from Kaffeine as I'm not sure if the problem is in the application, driver or somewhere else.

Hi,

Strange scenario. You're not saying anything about input types and the switch type. Are you sure that are properly connected ? How the switch inputs are marked and from where you got the input signals ? Please elaborate, if you want a proper answer.
I suggest to play with 'scandvb' from dvb-apps package instead of Kaffeine. Look into scanning results if the scanned channels match with what you wished to have on those positions.

Hi,

What do you mean with input type?

Anyway, this is my config:

Visiosat Bisat G3C for 19.2/28.2/23.5 + Triax 54cm for Hotbird 4 quad LNBs

Spaun SAR 411F:
A = Astra 19.2
B = Astra 28.2/Eurobird1
C = Astra 23.5
D = Hotbird

Maximum 4/1:
A = Astra 19.2
B = Astra 28.2/Eurobird1
C = Astra 23.5
D = Hotbird

All works fine on a standalone so it is connected correctly.

Hi,

Ok, If I understood you correctly, you're talking about only plain DiSEqC switch, with no polarity/tone management. Polarity and tone switching are done by LNB's.
Recently, I found a branded switch, which was unable to decode a DiSEqC commands while polarity was on horizontal (18V).
Maybe is the same situation, maybe not. That's why I asked you to check the polarity/tone settings of the channels while switching to a different channel on a different satellite.

That's right, no multiswitches or something like that. The last time I
checked (a while ago), the Spaun was still completely working on my standalones. But as I figured out yesterday, something is wrong with that now. The standalones don't see D (Hotbird) anymore either. So I'm first going to fix that.

Trying to switch from Flaunt (V) to 4fun.tv (V) doesn't work either, so it's not the same problem I guess.

Hello All,

Maybe I have the answer:
I also had problems with switches and LNBs which did not want to work properly. Behind 1 receiver it worked properly, but behind another 2 different DVB-S PCI cards, it just failed. I never suspected the LNB/Switch setup, because it worked behind another receiver.
But, In the end it turned out that there was 1 LNB in my setup that caused all the trouble, that LNB refused to cooperate with the switches and other LNBs, when a DVB-S PCI card was used (both Technisat Skystar 1CI, and TT-S1500). Once switched to this LNB, the complete setup failed to work from that moment on. I could never switch back to 1 of the previous LNBs, but the last (buggy) LNB still worked if I switched back to it.

So, my advice is to start with 1 LNB behind a switch, once it works, add another one, check if both LNBs still works, if so, add another LNB and so on. Maybe you end up, just like me, with 1 LNB that destroys the complete behavior.

So, my 3 TT-S1500s are properly working here now with MythTv and DiseqC switches with 4 LNBs per card/switch. So, it _can_ work...

Good luck!

Kind Regards,

Remy

Hi,

Can you explain how you select those 4 positions ? DiSEqC commands or tone/voltage changes ?
Also can you determine the input type of those positions (Hi/Low, H/V, etc) ? A scenario to see when and why that happens, would be more useful.

Hi,

I've got a Technotrend S-1500 (if it matters: I use it with Kaffeine 0.8.3). It works mostly fine, but there's a strange problem. With my Spaun 4/1 DiSEqC switch (they cost approx 25-40 euro), I can only switch without trouble to position 1 and 2. If I tune directly to position 3 it won't lock.

However, if I first tune to a channel on position 1 or 2 and try a channel on position 3 after that, it will work. Position 4 however is completely unreachable.

On a standalone receiver, there's no trouble with the same cable.

Now Spaun is a really expensive and respected brand. So their switches possibly work in a different way, because a cheap Maximum 4/1 switch works perfectly with the S-1500. Position 1, 2, 3 and 4 all work perfectly. I also did some "dry testing" indoors and it looks like a 7 euro Satconn 4/1 switch would also work fine, but a 17 euro Axing SPU 41-02 probably won't.

I'm guessing this could be solved in stv0299.c but I'm not much of an expert. I took a look at the code but I'm not really sure what to do.

I select them with Kaffeine. Hi/low and H/V doesn't matter. I tried upgrading to Kaffeine 0.8.5 but that doesn't make a difference. The "scan" application has the same issues.

Nobody any ideas? If not, does anybody have some idea what the difference between position 1+2, pos 3 and pos 4 could be? I was thinking 1 and 2 might be working because of toneburst, but I don't think Kaffeine uses such a signal and that doesn't explain why pos 3 works if first tuning to 1 or 2 and 4 doesn't work at all.

I've figured out a bit more. If I tune directly to postion 3, I get pos
1. Whenever I tune to pos 4, I get pos 2.

I'll also ask people from Kaffeine as I'm not sure if the problem is in the application, driver or somewhere else.

Hi,

Strange scenario. You're not saying anything about input types and the switch type. Are you sure that are properly connected ? How the switch inputs are marked and from where you got the input signals ? Please elaborate, if you want a proper answer.
I suggest to play with 'scandvb' from dvb-apps package instead of Kaffeine. Look into scanning results if the scanned channels match with what you wished to have on those positions.

Hi,

What do you mean with input type?

Anyway, this is my config:

Visiosat Bisat G3C for 19.2/28.2/23.5 + Triax 54cm for Hotbird 4 quad LNBs

Spaun SAR 411F:
A = Astra 19.2
B = Astra 28.2/Eurobird1
C = Astra 23.5
D = Hotbird

Maximum 4/1:
A = Astra 19.2
B = Astra 28.2/Eurobird1
C = Astra 23.5
D = Hotbird

Quoted 7 lines

All works fine on a standalone so it is connected correctly.

Hi,

Ok, If I understood you correctly, you're talking about only plain DiSEqC switch, with no polarity/tone management. Polarity and tone switching are done by LNB's.
Recently, I found a branded switch, which was unable to decode a DiSEqC commands while polarity was on horizontal (18V).
Maybe is the same situation, maybe not. That's why I asked you to check the polarity/tone settings of the channels while switching to a different channel on a different satellite.

That's right, no multiswitches or something like that. The last time I
checked (a while ago), the Spaun was still completely working on my standalones. But as I figured out yesterday, something is wrong with that now. The standalones don't see D (Hotbird) anymore either. So I'm first going to fix that.

Trying to switch from Flaunt (V) to 4fun.tv (V) doesn't work either, so it's not the same problem I guess.
