Re: Geo usb2 box

Ulrich G. Kliegis
 

Some time back I bought a pair of those Dexatek boxes, before the DVB
World ones were available from the GEO Shop. I'm using one (on PC
Gemini) and Ian is using the other, and I'm completely happy with
mine.
David,
I got pretty far tonight, although again not without some obstacles in the
way, and I am not yet quite there.

Hardware: i-Tek Sphere.
The installation software (incl. driver) on the included CD, started from their
menue, stalled at the time of driver installation (installing drivers, please
wait.... endlessly). The same with the V3.0 software from DVB World.

Uninstall everything, start over again. New hardware found, manual
selection of the DVBS2102USB driver. Driver installation runs through, I'm
Mr. Happy, until - the box appears as an Audio Video device now. Now
install the software only (V. 3.0 from DVB World again), it misses the audio
part (no wonder, I disabled onboard-audio in the BIOS when I set up this
PC, keeping it slim). But it starts, I can configure EB9, have to add all PIDs
manually, 'Testbild' appears in the programme list (this confirms that the
LNB looks at the right spot), but there is no image. Probably because of the
missing audio. No data taffic either, though. Quality about 82 %, strength
about 72%.
Start IP is refused - a warning dialogue (well, monologue): There is a
problem with your DVB interface...
Now, the USB Box is listed as a network device. Setting the IP to
192.168.238.239 (and ~237 as the alternative address) does not help. The
Technisat-card is still in the PC, but the antenna cable leads from the LNB
to the USB-box now.

Any idea, anybody?

Still XP Pro...

Cheers,

U.

Re: Geo usb2 box

Ian Deans
 

Hello Ulrich,

I have been using a Dexatek USB Box now for well over 3 years and it has worked perfectly on a 1 computer system. The box I am using was actually a spare one David had and he helped me set it up here using the instructions still available on his site.

I had bought a new computer earlier that year with Vista installed ( that operating system had just been launched then ) and my SkyStar card was causing severe losses and in spite of weeks of experimenting and testing I was unable to resolve the problem.

The Dexatek box and the DVBWorld boxes sold by GEO are identical inside and the Dexatek box uses DVBWorld drivers but has its own software although I run DVBWorld drivers and software on my Dexatek Box. Software and drivers from DVBWorld particularly over the last 2/3 years have problems. However I have tested and tried every driver and software available ( 64 bit only ) and can get them all working OK.

I would very strongly recommend you trying the Dexatek box,but if you download the latest Dexatek drivers / software from their site ( see below ) and dated 16/6/2009 you should find these OK.

http://translate.google.co.uk/translate?hl=en&sl=de&u=http://www.dexatek.com/Download.asp&ei=LCh5Tc3WK9GJhQfdkNn7Bg&sa=X&oi=translate&ct=result&resnum=3&sqi=2&ved=0CCwQ7gEwAg&prev=/search%3Fq%3Ddexatek%2Bdrivers%26hl%3Den%26prmd%3Divns

Hope that has been of some help.

Regards
Ian.

If you were using an old Technisat box it would be USB 1 and they are

Ian,
a week ago, I did not know yet that I had a missing packets problem. After
installing MRTG, this became apparent, and since then, things have got
worse with each step I do. I defragmented my disks, adjusted the
"parameters" in recv.ini, maximized the signal strength from the LNB, but
nothing is what it was any longer. Last night, lifting the priority of tc-rcv.exe
(both instances) to 'realtime' seemed to stop all problems, zero missing
packets for hours, but then it started again after just changing the maximal
bandwidth a bit.

You can trace this all back on http://eumetmon.rummelecke.de/index.html

David said the 0 BER value says more or less nothing about the real quality
of the Technisat PCI 2.6D card's signal quality.

Now, I have a Dexatek i-Tek Sphere USB box here, would the effort of
installing that ( I read somewhere that the startup-parameters setting is a bit
awkward) be worth a try? And is it still fast enough? - I just want my nice
RSS sequences back, and all the other good stuff I had before... since I
started this somewhen around 2003... Sigh.

Ulrich,

Some time back I bought a pair of those Dexatek boxes, before the DVB World ones were available from the GEO Shop. I'm using one (on PC Gemini) and Ian is using the other, and I'm completely happy with mine. It handles Meteosat-9, EARS-AVHRR, MODIS-L1 and Metop AVHRR. I expect it would cope with Meteosat-8 at the same time (it certainly will if the DVB World box can), but I haven't actually run that myself. You can see PC Gemini's performance here:

http://www.satsignal.eu/mrtg/performance_gemini.php

It's running Windows Vista (32-bit) and while it's not lossless, all missed packets (say 10 a day) are usually recovered. At this instant, it's actually running the unreleased TelliCast 2.5.17 client. In addition to EUMETCast reception and processing, it also runs the Kinetic SBS-1 Base Station (virtual radar) hardware and software, and the Plane Plotter software, plus a couple of related add-ons.

The only area where is doesn't do as well as other PCs is in timekeeping, but it's usually within 10 milliseconds or so.

Now I am /not/ recommending that you change, but if you are in experimenting mode it's certainly worth a test. As Arne shows in the present GEO Quarterly (how to receive both EUMETCast and ENVISAT on the /same/ PC), you can actually have /both/ the PCI card and the USB box running at the same time, if you give them different IP addresses. Of course, in your case, only one would be working at any one time, but it means there's no need to uninstall the "other" software. Set the newly added box to 192.168.238.239. Beware that, as usual, the network interface numbers are likely to change, affecting MRTG.

Cheers,
David

Good news Duncan that you are now running without losses.

If you were using an old Technisat box it would be USB 1 and they are no longer suitable for Eumetcast as they cannot handle the high data rates. It is worth mentioning though that Technisat now have two USB 2 receivers that should work fine on Eumetcast.

You may have seen that on 07.03.2011 I had a day of receiving and processing Metop data and then yesterday virtually no data was received. Today data was again received but not processed as my temporary licence had expired.

I attempted to register but have been met with the message............www.satsignal.eu/software/reg-metop-manager..........Application not found.

This further strengthens my belief that there is something very odd about the original installation of this programme.

Ian & Alan

Last week when I raised my problems with Eumetsat and asked them to check my connections they confirmed that i was correctly connected and also asked for a whole mass of information.

Below is the answer.

Regards........................Geoffrey




Notification No : 300014191

Dear Geoffrey Gee,

Subject : 300014191 EUMETCast Reception Issues

I have received the below for you from our engineer

**********************
First thing, his recv-channels.ini file is configured to write data into
the:
target_directory=C:&#92;received&#92;Data Channel EPS-10

If as he says in his e-mails, he wants it in just �EPS-10� he should
change the entry to be:
target_directory=C:&#92;received&#92;EPS-10

Looking in his recv.log he is getting a file occasionally, e.g.:
VRB:2011-03-06 19:29:45.811:Delivered file `C:&#92;received&#92;Data Channel
EPS-10&#92;AVHR_xxx_1B_M02_20110306175503Z_20110306175803Z_N_O_
20110306192640Z' id 4d73e083001b5a4d from channel `EPS-10'

A big HOWEVER, there any many many:

MSG:2011-03-06 19:25:37.976:Channel "EUMETSAT Data Channel 2": Lost
message 382 (message lost)

MSG:2011-03-06 19:25:37.976:Channel "EUMETSAT Data Channel 2": Lost
message 383 (message lost)

Type messages in his recv.log. This points to either a reception or
performance problem. As the MSG data are fine (and have been for a few
years) I suspect that the problem is related to the performance of his
PC � the most likely suspect being the disk performance. He does not
appear to have a RAMDISK installed, I would strongly recommend he does
this as the EPS data are disk intensive. He should read the relevant
sections of the trouble shooting guide (D1, D9, D12)

*******************


Re: New to Metop

geoffreygee90
 

Ian

My apologies for not being specific and also missing a reply to your previous message.

To add to the information in my last mail.


Yes the data was Metop it went into Data channel EPS-10 and was processed by Manager and then deleted for 07.03.2011

As reported Metop Data on data channel EPS-10 stopped a.m 08.03.2011 after a few chunks. On Data channel 1 it came in all day.

Data channel 2 ,3,4,nothing.

NOW this morning data is coming in on all channels except 3.

I have made no alterations to any parameters. Today my free use of Metop Mgr has ended.


Hope this gives you a better picture of what has happened.

Best regards..................................Geoffrey


Re: New to Metop

Ian Deans
 

Geoffrey,

You will need to be more specific when you are mentioning data. When you say data stopped at lunch time are you talking about all the Eumetcast data you take or just Metop. As you haven't replied to my previous mail I do not know if you are receiving Metop.

Ian.

Thanks for prompt reply and information

If the programme is not seeing any data...................why not and where have I gone wrong ?

Regards.........Geoffrey
Geoffrey,

Obviously, the first thing to check is where - in recv-channels.ini - you have the [EPS-10] data going to - typically it might be:

___________________________________
[EPS-10]
target_directory=received&#92;EPS-10
___________________________________

and then make sure that in the Metop Manager, Setup, File COntrols, Global EPS Metop Data, AVHRR, you have the received files path pointing to the same directory. It should have files named like:

AVHR_xxx_1B_M02_20100614143403Z_20100614143703Z_N_O_20100614160139Z

If someone is going to help you with the RAMdisk, I would rather leave it up to them to help further, rather than have two different people giving you contradictory advice.

David

Ulrich,
David,
and whoever helped in this thread


I doubt we will get much further in this thread. Even if I hate forms I think we will need a basic kind of "form" with questions to be answered by people that have as severe receiver problems as this. All needed information that should be handy for different reasons is so fine spread over many days now that I am quite sure we don't even have very similar conceptions of the system we are talking about. Maybe this form already exists somewhere and can be used as is or after some updating. EUMETSAT certainly has quite a clear idea what you have to provide when asking for help (see their trouble shooting guide).

This said I try to lay out my information of Ulrichs system. Without rereading all that has been written on this list, I think we are talking about something similar to:

- PC running XP pro (service pack unknown to me)
- Make of PC motherboard (unknown to me)
- Bios possibilities and settings (unknown to me)
- Processor, speed and amount of RAM (unknown to me)
- RAM Disk with 325MB FSY limit, drive letter R: used
- TelliCast Client 2.4.4B running with admin rights
- One version of recv.ini and recv-channels.ini provided
- SkyStar 2.6D PCI DVB card (driver version unknown to me)
- Some sort of Toroidal Antenna (appearently with other LNBs)
- DeLock PCI SATA 1.0? Card, maximum 150 MBytes/s (20 Euro Chinese?)
- Two SATA Hard drives partition E: (Drive1?), partition F: (Drive2?)
- Satellite raw data are split on E: and F: partitions
- System software somewhere on C: (probably on Drive1)
- Page partition instead of page file (has this been D:?)
- What PIDs are enabled (unknown to me)
- MRTG shows high throughput on DVB interface
- 100 MBit/s network interface, network setup?
- Processing software and setup (unknown to me)
- No Anti Virus actif on receiver
- Defragmentation off by now
- Firewall is off on receiver
- Routing table (unknown to me)
- Graphics Card (unknown to me, hopefully not PCI too)
...

Maybe this is not very ordered and some answers will certainly mean more to people that actually run an EUMETCast receiver under XP Pro (as I am using Debian and Ubuntu GNU/Linux). And it's certainly not yet all the questions that should be put on that form.


Symptoms are lots of lots of packet loss, RAM disk filling up very fast after reboot. Recv.log shows ended filelists lost messages and lost files in different channels. Situation slightly improved when reducing file_delivery_speed setting to 5'000'000 which is only half the TelliCast Client default and 10% of what it was to begin with.


I may be wrong but I doubt that the system has ever worked very well in this configuration. My guess is this (and I still have to guess after all that ...):

The hard disk setup seems to be rather unappropriate fo an EUMETCast receiver. A SATA PCI addon card (that struggles for supply current with the SkyStar 2.6D). This card may well IDE emulate the two SATA disks in an Master/Slave way for the OS (which should eventually be found by clicking through the Windows XP device manager). This means: Whenever Master is doing something, Slave has to wait! Now let's turn
on this setup in our heads. Assuming C: on Disk1 the OS will have business there then and when. The page partition might be D: and the head has to move all over the place as Windows XP pro is paging frequently even with lots of RAM. Then and when there should be raw satellite data written on E: on the other end of the disk, then logging recv.log on C: again. Slave F: is still waiting but has some raw sattelite data too ... If the Slave finally gets its share, the Master drive has to wait for his turn. If Ulrichs system is anywhere close to what I'am talking about it should eventually be rebuilt.

Rotating even 30 log files is "childs play" for a well built client and OS and certainly not the problem. It might still be worth rearranging the PCI cards. TechniSat e.g. asks not to put the SkyStar at the side of an PCI express Video card. Also a RAM disk can probably not work as it should even if the RAM itself is flawless.


How a good disk and partition setup should look like has been pointed out by David and others on the list. My proposition is (what I use under GNU/Linux):
Drive1: C:&#92; for OS, System Software, TelliCast Client, ... Maybe processed data.
Drive2: D:&#92; for raw Sattelite data only, for XP pro use drives with enough cache

Both drives should be on totally independant IDE controllers or SATA channels. There should be as little PCI cards as possible, this makes the SkyStar2 happy.


Under GNU/Linux I can setup a well working system in less than one day. I have not had one lost packet for the last 6 weeks on both my receivers turning 24/7. I don't see why this should be far more complicated under Windows XP pro. So Ulrich, I think, maybe after a closer look at the PCI bus situation and the RAM disk, you should begin to consider to redo your system from ground up. And don't do this without reading the EUMETSAT trouble shooting guide and surfing some time on Davids site ...



Cheers
Ernst


P.S.
If this system setup really worked as posted some times back, even changing the LNB or the SkyStar 2 could be a last option ...


Re: New to Metop

Ian Deans
 

Geoffrey,

Good that data is flowing again, but can you confirm if that includes Metop data. If you are receiving Metop data which is not being processed then you will see the data building up in C:&#92;received&#92;EPS-10. Even without a RAMdisk I would expect you to be able to get some Metop data although likely with gaps.

Ian.
