CMS50D+ connection problem

ragnar33 · Post by **ragnar33** » Wed Jun 17, 2015 2:31 pm

Hello, I got a new computer and are moving everything over. So far only one problem, new computer, Windows 8.1, does not seem to recognize the oximeter. I installed the CP210x USB to UART driver version 6.7, 64 bit version.
When I run the SPO2 Review, version 1.5 I get a message that the device is connected, but no data is transferred.
Should I try the 32 bit USB to UART bridge or does anyone have any other suggestions?

Call Kevin at (his) company and talk to him - he's really helpful and will know what to do.

I had one for a short time and they are not very logical to record and pull data out. I wrote up notes on it, but I can't find them right now.

make sure you're using the proper cable, the cable that comes with them is *NOT* a usb cable, even though it looks like one on the surface.

Thanks Julie, but who is Kevin and what is his company?

Thank you palerider, I forgot to mention that I am using the correct cable.

Thanks to all, suddenly the download works. I decided to try a "live" connection using the red SPO2 app and lo and behold I saw the pulse waveform.
Other than that I am not aware of anything I did.
Now I just have to find out where the file was saved (:-))

Once the ox is connected to the computer's port and when you are in the Sp02 Review app (green in color) and have given a name to the 'New Session' you must turn the oximeter ON, then let go and press again until you get the menu which includes the RECORD function, make sure RECORD is turned OFF, and it should upload your overnight recorded data automatically. Depending upon length of testing, it usually takes 30-45 seconds to upload the data and it will display for you.

I have found the ox and program easy to operate (once one gets over the learning curve), and have recorded overnight about 45 times.
OXIMETRY REPORT:

---------------------------
STRIP CHART:

Comments that I wish to share with you: I've found that Sp02 >95% varies greatly. Above, it was >95% only about 3.5% of the time.
On 6/6/2015, it was >95% 48.3% of the time:

I am finding that going STRAIGHT CPAP works for me better- I sleep better and longer due to the constant pressure.
Moreover, I have considerably fewer Desaturation Events with straight CPAP in comparison to going AUTO.

Hope these additional comments are helpful!

which has 100% to do with the topic at hand which is CMS50D+ connection problem

isn't that about 100 too many percents?
