Data not read on Resscan 3.3

risktaker99 · Post by **risktaker99** » Fri Jul 11, 2008 8:21 am

I just bought the ResScan 3.3 software and ACR 38 Card Reader from CPAP.com. That's the good news. However, after installing the software and attempting to download the data from the card, I continually get the following error:

Invalid Session No in KPacket

Does anyone know what the problem is? I tried uninstalling the drivers. I also tried waiting another night and then copying the data from my flow generator onto the card. I guess it's possible that the card is corrupt but I never used it before and unfortunately I don't have another one.

Unfortunately, I don't have any suggestions - but - I can verify that ResScan 3.3 does recognize and is compatible with the Resmed S8 AutoSet Vantage. I've had and used both together. Even the previous AutoScan 5.7 recognized the Resmed S8 AutoSet Vantage.

ResScan 3.3 does NOT recognize the Resmed S8 II devices.

That being said: are you waiting at least a 1/2 hour after rising before downloading to your data card? (I seriously doubt that is the problem).

Are you connecting the cable directly to yuor 'puter or are you using an extra cable so you don't have to reach to the back of your 'puter to connect the cable reader? (This "could" be the problem tho it hasn't been for me).

Have you tried the obvious? removing the data card, reinserting it? from both your Vantage AND from the cable reader?

Have you taken a good look at your card to see if it needs to be cleaned? Sometimes alcohol will clean the card and gold "spot" where the data is held. Sometimes it requires a SOFT eraser and then the alcohol. (This would be unlikely w/a new card. However, if your local DME or sleep lab has down an upload from your card to their software they may have erased the data and/or may have given you a used card in return).

And, please, don't be insulted: have you inserted your card gold spot DOWN into your Vantage and gold spot UP into the cable reader?

Slinky:

To answer your questions:

yes, I did wait 1/2 hour before downloading.

I connected directly to a UBS port on the PC with the card reader cable.

The card is a new card that has never been used. I guess it's possible that it is corrupted?? I will try wiping the contacts with isopropyl alcohol but I don't think that's the problem.

Yes, I did insert it up vs. down. That was not a dumb question. Initially, I didn't since the procedure is just the opposite on the vantage side vs. the card reader. When the card is inserted and I click on download in the ResScan program I can see that it is attempting to download the file. It goes up to "3% downloaded" before giving me the error.

Also, when I insert the card into the Vantage, it does seem to process the card. It tells me that its downloading the data. Then, it says it's complete.

How many nights of data are in your Vantage? I never did a big file w/ResScan 3.3 but I've not yet been able to import my AutoScan 5.7 file into ResScan 3.4.

Fortunately, I kept a separate file for my Vantage as well as incorporating it into my main file w/both Elite and Vantage. That smaller file imports easily into 3.4 - but NOT the main file. It HAS to be because the file is too big. It "might" because of data from two different devices but I don't think so. Would DME's or sleep labs start a new file for a patient just 'cause they got a different device of the same brand? I don't think so. Something I'll have to ask my sleep lab manager.

You know, BillBolton or DSM would be better ones to ask. Or Velbor, altho Velbor isn't around the forum as much as DSM and BillBolton.

I would guess there are 100 days of data. One question I have is if I download the file onto my computer from the card reader, does it automatically delete the file from the card?

I will try to reach out to DSM.

Hmmmm. I didn't install my ResScan 3.3 or 3.4, my 'puter guru did, so I don't know if the default is NOT to erase the data or if he set is so that it wouldn't. I know the option is there to erase or not.

I know when we installed my EncorePro I warned him specifically to be SURE to set the option to NOT erase as I'd read here in the forum that the default was to erase. (Yeah, I had a Respironics for awhile - sold it to my son-in-law to get the Vantage).

It may well be that he remembered and so did set it to NOT erase if the default was to erase.

Another question for DSM, BillBolton or Velbor!

I just checked. I dug out my Elite and did a download from it. I had used that Elite from Jan 07 to 24 Mar 08. Yet the download to ResScan 3.4 only went back to 26 Sep 07. A total of 181 days (1362:50 hours).

Would have to go back to check my Manual but I do know there is a limit to the number of nights of data the card will hold and there's also a limit to the number of nights of data the xPAP itself will hold.

Regardless 181 nights is more than the 100 nights of data you are working with.

You've got me stumped ("ain't" hard to do!).

A ResScan card will hold 180 days of summary data, with detailed data also held for the most recent 5 days out of those 180 days.

The S8 flow generators internally hold, IIRC, pretty much a years worth of summary data and you can download that with a direct USB connection from the S8 (requires a USB adpater module to replace the card module on the S8 ), so the 180 day limit is related to the storage capacity of the ResScan smartcard,

In my general experience with both AutoScan and ResScan software, the ResScan card operation either works properly, or doen't work at all and throws up a "no card" or similar error message.... which means the card reader device drivers are not working as expected, or occasionally that the card is not making good contact with the reader contacts.

I've never had it partially work and then stop with the sort of error message reported above!

Regarding leaving the S8 for a while before loading dara on the card, I always turn power to the S8 off and then restore it before loading data onto the card, so that may have something to do with my good results.

By the way, I'm not sure if I have mentioned this before not, but ResScan 3.5 is running well for me on a Vista x64 system. I've now decomissioned my last general purpose XP PC, so I'm not using AutoScan at all anymore.

Cheers,

Bill

Slinky - I think you'll find the Resscan uses separate files for every day - not one big file.

Slinky · Post by **Slinky** » Fri Jul 11, 2008 10:14 pm

Actually I haven't found that at all. I've been running a nightly file since 25 Mar 08 on ResScan 3.4. I do a download every day to every 2 days. Detailed and Summary data. 108 nights, 788:47 hours so far. All in one file. I just keep adding to it just as I did w/AutoScan 5.7

Have a look in your patient folder slinky - how many files are there? what are the days and dates?

dsm · Post by **dsm** » Sat Jul 12, 2008 3:04 am

On Autoscan I always kept each download separate. I would do a download & save the file then rename it with the date.

This has allowed me to keep years of data intact & across versions as I can import any file into any later version.

Keeping it all in one file has its risks

Oopsie! As I've recently found out whilst trying to import that one big file from AS 5.7 to RS 3.4, right, DSM?!!

One folder, BigK. No dates displayed in the folder. No dates until I open the file.

Ahhh, you guys w/your "logical" minds! *sigh* Why didn't you tell me this stuff sooner?

DSM, then you can't do a custom, weekly or monthly, etc. averages, doing it your way, right? Or am I wrong?

Ooops. I mean the software can't do the averages your way, you have to do it manually or via Excel or other software?

Oh, duh!!! BigK!

When I tried to import the large AutoScan 5.7 it does show up in the Patient Group. AND, if I click on it the NUMBER of files DOES show up in the uppe right hand corner: 3 files using 2.6 Kb.

I'm thinking the 3 files are because I started w/an Elite, then a recalled AutoSet Vantage, then the replacement AutoSet Vantage but ran the data from all three in the same patient file.

Sorry I was so dense about this at first.

Do you know a way to go back into AS 5.7 and break that one large file into 3 different files, one for each device?

Success!! I Fixed the Problem

I reread Billbolton's comment:

Regarding leaving the S8 for a while before loading dara on the card, I always turn power to the S8 off and then restore it before loading data onto the card, so that may have something to do with my good results.

I have always kept the power plugged in 24/7 on my S8 Vantage. I unplugged it and then plugged it in again (sort of like a cold reboot on a PC). Then, I reinserted the card into the S8...waited until it copied the info. I removed the card and then put into the reader. I pressed download ....and (drumroll....) it worked!!!

There must be some sort of programming bug that exists. I shouldn't have to reboot the S8 just to copy the card.

Now I have a couple of questions regarding the files. Does anyone know which files (extensions) can/should be backed up if I want to move them to another computer?

What procedure deletes the files from the card?

Again, Thanks to everyone for your assistance.
