Hey anybody here got one of the Tevii S480 cards?
Can you get a multimetre and measure the voltage from the two LNB F-connectors on the card please?

My card appears to be putting out 25V on both LNB connections and I am having issues tuning transponders.
The 25V is constant too even when the card isn't doing anything.
I've unplugged the floppy power connector but that made no difference.

My two Nova S cards only put out 13V or 18V when they are busy tuning a transponder so I think that the Tevii card has a fault.
I am also having problems with the Nova S cards so I'm wondering if the 25V from the Tevii card has damaged the Nova S cards???
The MySkyHDi box is hooked up at the moment to the same sat cable and it is working perfectly.

Was that measured with or without an LNB connected?

With no load, it may show 25v, but drop to 14/18 with the LNB connected...

What RunningMan said.

What kind of problems are you having with the Nova-S Plus - maybe something else could explain it.

I measured both the Tevii card and the Nova S cards voltage without the LNB connected - Just had a short coax cable attached to the sockets and tested the end of the cable.
THe Tevii was 25V constantly even if it wasn't busy while the Nova S would be 0V until I told Mediaportal to do a scan and then they would read 13V for Vertical and 18V for horizontal scans.
So I don't think having a load on there will make any difference to the Tevii card.

The Nova S cards seem to be picking up the wrong channels on the transponders, in MP TV Server.
EG: I did a scan of the Freeview 12456 transponder and both NovaS cards pick up 9 channels but they show as being Sky channels like the Box and Vibe.
If I then go to the Manual control and try to start a stream of one of the channels TVServer just says Unknown Error or something like that.
If I do a scan of the other Freeview transponder, 12483, they get no signal, on both NovaS cards.

If I connect the Sky box it works perfectly.

I've never had this problem before with the NovaS cards, they only seemed to start playing up when I got the Tevii card about two months ago.

Is it possible that you have the LNB settings configured incorrectly?
Most Sky LNBs these days seem to have 10750 MHz as the local oscillator frequency. If you are using the "Ku-linear (Universal)" band setting and haven't enabled the LNB setting overrides then you'll be scanning with 10600 MHz, which is not right. That could cause you to pick up the channels on 12608 H when scanning 12456 H and nothing when scanning 12483 H.

"Ku-linear (Universal)"
Low LOF = 9750
High LOF = 10600
Switch = 11700

If scanning 12456 or 12483 the high LOF will be used (since the frequencies are above the switch frequency of 11700).

Actual scanned frquenencies:

12456 - 10600 + 10750 = 12606 (close enough to lock on 12608 H)
12483 - 10600 + 10750 = 12633 (probably not quite close enough to lock on 12644 H)

Please enable the LNB override settings (tick advanced tuning options and enable LNB overrides) and enter 10750, 10750 and 12750 from top to bottom.

CYaBro: I measured both the Tevii card and the Nova S cards voltage without the LNB connected - Just had a short coax cable attached to the sockets and tested the end of the cable.
THe Tevii was 25V constantly even if it wasn't busy while the Nova S would be 0V until I told Mediaportal to do a scan and then they would read 13V for Vertical and 18V for horizontal scans.
So I don't think having a load on there will make any difference to the Tevii card.

Hauppauge tuners can also be configured to provide voltage even when not in use (there are registry params). Also, if you have done as above then the tuners should be generating a 22 kHz tone which may throw out your multimeter reading. The tone generator may not work for your Nova S Plus tuners (personal experience) which *might* explain the closer voltage matching. Having said that, if the TeVii is providing a constant 25 V (ie. even when scanning vertical tranponders) then the tuner/card may be bad. Are both TeVii tuners behaving the same?

Depending on how that card regulates the supply voltage, it could make a significant difference if there is no load when measured.

Even so why is it putting out 25V constantly?
It should turn off the voltage when the card is not doing anything.

I have got it set to KU Universal but also have ticked the overide option and have put in 10750 for the Low LOF and nothing in the other boxes.
THis is how I have always done it in the 3-4 years I've had these NovaS cards in TV Server and never had a problem.
I will try your suggestion tonight though.

And yes, both LNB outputs in the Tevii card read 25V constantly.

Thanks.

EDIT: FOrgot I have remote access to my server at home now :)
Just put in the 10750 for the LOW and High LOF and 12750 for the switch and it seems to be working now!
I only have one NovaS connected at the moment so can't say 100% that both cards are working but I'm sure it will. :)
I will also try the same settings for the Tevii card and see what happens.
Thanks!

EDIT2: Dammit spoke too soon! It started scanning OK, got about 7 of my 15 transponders scanned and then the rest say no signal. The channel list also has a whole heap of Unknown 3FC etc - way more than normal. - Every scan give the exact same results.

Do you think you could put your TV Server logs up somewhere?

1. Open TV Server configuration.
2. Click "open log directory" in the top left corner.
3. Zip up the files you find there and upload to rapidshare or similar.
4. Post link.

I'll see if I can see any evidence of signal corruption or strange behaviour.

I didn't include .bak files or most of the tswriter files as they probably aren't needed? I left the latest couple in but let me know if you need more.

Thanks, that's better.

Looks to me like the problem earlier was that one of your LNB settings was not able to be converted to a number, so TV Server was using the wrong LNB parameters behind the scenes. That is resolved and right now it seems like you've got signal quality problems. The "Unknown ***" channels and slow scan times mean that the service description table is not being received. I suspect that is most likely because the packets are corrupt and being dropped. You could try disabling the plugin that I won't name temporarily as that could have a corrupting effect but it can't prevent signal from being found. In other words, I think it would be most productive to check your cabling at this point.

OK thanks will have a go.
I don't think there is a problem with the cabling though as MySkyHdi box works perfectly on all channels.
I even tested the sky box on the 4 way splitter, on all outputs, to make sure it wasn't that causing the problems.
It's only about 10m RG6 cable from LNB to where the equipment is.
The signal metres in TVServer say that, for the transponders it is getting a signal on, the signal level is 100 and the quality is 90 so that should be OK shouldn't it?

One thing I noticed in the logs is this:

frequency:12407000 Symbolrate:30000 Polarisation:2 FEC:2 S2:0 RollOff:-1

Why is that showing when it isn't even in my transponder file??

Could the LNB be faulty?
I have 2nd Sky dish on the roof that I could swap the LNB from if it's an easy job???

I can't really say more than I've already said - something just seems off and that is my best guess on what it is. Don't read too much into signal strength and quality measurements as they are meaningless except when comparing relative values on the same device. Tuners have different sensitivities so one tuner can struggle with conditions where another will operate fine.

One thing I noticed in the logs is this:

frequency:12407000 Symbolrate:30000 Polarisation:2 FEC:2 S2:0 RollOff:-1

Why is that showing when it isn't even in my transponder file??

I guess you see that in the TsWriter log. It is coming from the NIT (network information table) and presumably references either the transponder on Optus C1 or D3. I can't explain why it is there except to say that Sky and/or Freeview are including it in their list of transponders. It is certainly not a TV Server thing; the logs just report what is in the stream...

Could the LNB be faulty?
I have 2nd Sky dish on the roof that I could swap the LNB from if it's an easy job???

Anything is possible I guess. You know the system better than I do so you know what is "normal" and the sequence of events that have lead up to this point in more detail. If you have adjusted dishes and LNBs before and you think you've done the other logical tests to rule things out then there is probably no harm. If it were me I would confirm that both Nova S Plus tuners were returning roughly the same results to eliminate other possibilities.

mm
PS: when you scan, I recommend you fill in the correct inner FEC rate (for Sky and Freeview it is 3/4). All the other parameters that you chose seem to be correct (including modulation - that should be "not set" for DVB-S and 8 PSK or QPSK for DVB-S2).

Well I'm stumped!!
I got home and connected all 4 tuners back up to the dish and did scans on each tuner, with the 10750,10750,12750, and they all seem to be working now.

Edit: Deleted as I see the answer above thanks!

Edit2: Well I spoke too soon again! I think there must be something up with the Tevii card as scan on either of the tuners has random 'Nothing Found' messages or 'No Signal' on random transponders.

It seems very random too as to when the Nova S cards get a signal or not, when the Tevii tuners are connected.
