USB Download from Contec Oximeter to Mac

I don't own a CPAP (yet), just a recording pulse oximeter (Contec CMS50D+).

I don't own a PC.  I have an iMac, running OSX 10.10.5 (Yosemite).  

I bought the pulse ox based on the fact that Sleepyhead software was supposed to be compatible with both my oximeter and my operating system.

This was the sequence of events:

I downloaded SiLabsUSBDriverDisk (v. 4) and installed it.
I downloaded Sleepyhead (no version; says created by Qt/QMake) and installed it.

After recording all night long (in record mode), I plugged my oximeter into my iMac using the cable provided, still in recording mode.

I opened Sleepyhead, clicked on Oximetry Wizard and clicked Start.

In the Oximeter Type pulldown menu, I selected CMS50D+.

Then I clicked "Import Directly from Recording on Device" and it said this:

     Scanning for compatible oximeters
     Connecting to  Oximeter
     You need to tell your oximeter to begin sending data to the computer.
     Please connect your oximeter, enter it's menu and select upload to commence data transfer...

There is nowhere in the menu of the oximeter to "select upload".  After a while, I got this error message:

     Could not get data transmission from oximeter.
     Please ensure you select 'upload' from the oximeter devices menu.

Based on something I read on the internet, I made Sleepyhead Read only access for myself and everyone else, and locked it.
After repeating the above process, there was no difference, same error message.

Then I turned off the recording mode and repeated all of the above.  No difference, Same error message.

Then I reset Sleepyhead to the orginal "unlocked" and Read/Write for me, Read Only for others.  No difference, same error message.

The menu on the oximeter is very simple.  There is no way that I could miss the setting "upload" on it.  There is no such setting.

Anybody have a solution to this?

Hi JazG! - Welcome

The 50D+ is a unique animal in the oximeter family and requires you to pat your head and rub your tummy to get it to connect.  Several users of this device have reported difficulties in the past.  Here are a couple of links. I hope they may shed some light on your problem. I used the search term, "cms-50d+" and went down the list.



Good Luck!
