S9 data discovery (may be well-known)

Found something new (to me) on the S9 this morning. I was trying to see what information I could get out of it without having to download the SD card. Turns out that you can not only get your report out of it, but you can set the period of time over which the report is done. I thought that it was just 1 month, but you can change the period to 1 day, 1 week, 1 month, etc. out to 1 year, just like in ResScan.

In case you don't know how to navigate there using the S9 controls and display, just press the top and bottom rectangular buttons at the same time, and you'll see a bunch of choices added to the menu on the first (left-most) column of the S9 display. Then you can rotate the dial knob to get to the "Sleep Report" menu item. If you then push the dial knob in, you're set to look at your sleep report. The "Period" is the first item there, so if you push the dial knob again, you can then change the period of the report by turning the dial knob. Then just push the dial knob yet again to accept the period that you've selected and then you can turn that self-same dial to see all the parameters of the report displayed.

The only catch is that if and when you reboot your S9, it will go back to a Period of 1 month. Unfortunately. Since I always turn off the power before removing the SD card, I have to remember to reset the Period back to what I want to use most of the time.

You may have to have "Sleep Quality" set to "On" to do this, but I'm not really sure of that, since I never turn it to "Usage" myself.

Anyways, I was pleasantly surprised to see how much information you can get out of the S9 without having to download the SD card.

The different reporting periods are available on the S8s, too. Accessed differently, of course.

And why do you shut down your machine before removing the SD card? Do you do that with your PC, too?

Since you ask so nicely, my computer has an eject for media like an SD card..and the SD card is set to "write-only" when I put it in the computer. My preference, feel free to do it your way at your house *smile*.

Thanks for this information! I have a used S9 and havent' set it up myself yet (except to set the prescribed pressure)

Hidden message: any help and tips appreciated!

I see where your coming from. I've never worried about the SmartMedia card in my S8 ResLinj being corrupted as long as it was not
removed during therapy or shortly afterwards. Never had a problem. I'm about to get my first machine with an SD card.

I believe that PR System One machines display a message when the card is being updated. But you can't be too careful.

Your S9 also has an safe eject provision for the SD card, just like your computer does, although activated differently. When you push the card further into the port on the back with the power on, it activates the S9's auto-eject sequence, updating the card and then pushing the SD card out far enough to remove the electrical contacts on the SD card from contact with those inside the S9's port. If you remove the card by just pulling it out, or even by using the push/pull method but with the power turned off, the SD card may not be fully updated or completely sync'd with the S9.

I do agree that it is wise to set your SD card to write-only before inserting it into your computer, and back to read-write when reinserting it into your S9, but that is an entirely different issue.

This is what the ResMed S9 manual says about removing the SD card:

"SD card
An SD card has been supplied to gather therapy data from your S9 device and provide settings updates from your clinician. When instructed to do
so, disconnect the S9 device from the power outlet, remove your SD card, insert it in the protective folder and send it to your clinician."

Whoever wrote the above (from the ResMed S9 AutoSet and Elite Welcome Guide) apparently wasn't aware of what you're saying above. While I haven't seen confirmation of what you're saying about syncing when removing, I have seen the instruction to unplug the S9 before removing the card in several places in ResMed documentation. So I've been following that.

As far as device buffering goes, I assumed that their reference to turning off the power before removing the SD card meant that whatever buffers they're using when they write data, they would be flushed when a session is done.

Hi Roger,

Turns out that this fascinating debate has appeared here before too:

viewtopic.php?f=1&t=66598&st=0&sk=t&sd=a

There are also videos on the web from vendors some showing it being removed with no caution about powering down or unplugging, and some telling you to do it, but I guess I can't dispute your point about the manual, so I defer to you!

Best wishes, Nate
