Pulse Oximeter Contec CMS50F
#1
Pulse Oximeter Contec CMS50F
Hi,

I have the following configuration:

1.      CMS50F:
        a.       Hardware version 2.0.0
        b.       Software version 2.0.4
2.      I have downloaded SpO2 Assistant and OScar 1.0.1.1-r-1 (is running well)
       a.       Version SpO2: 3.0.4
3.      I’m using Windows 10 Professional, 64 bits with latest updates.
4.      I have installed USB to UART:
       a.       Silicon Labs Virtual COM Port (VCP) Universal Driver for Windows 10:
       b.       Package version: 10.1.8
       c.       Release date:    2019-06-24
       d.       This package contains a Virtual COM Port Universal driver for Microsoft Windows 10 for use with Silicon Labs VCP USB Serial Bridges.  These devices include the CP2102N, CP2102, CP2103, CP2104, CP2105, CP2108, CP2109.
5.      I have installed SpO2 Assistant.
a.       I search for by Connect Drive but SpO2 cannot see the pulse meter. (neither Oscar) Not automatic, not manual not USB and not Bluetooth.
b.       Under win 10 I have enabled Bluetooth and I see that ’Pulse Oximeter’ is shows in the list of connected equipment under Bluetooth.

With other words, The system win 10  sees SpO2 but the applications does not generate a read-out. It looks that USB to UART does not work but the driver says that everything is installed and ready.

Some can help?

Kind regards,

Gerard

Was there a CD/DVD that came with the oximeter when you bought it? Should have the software and drivers on the disk.

The cable used for the oximeter is not a normal USB cable. It's a USB to Serial cable (UART) and the unit will usually only transfer data with that cable. If you are using a regular USB cable it probably won't work.

RE: Pulse Oximeter Contec CMS50F
Is your CMS50F turned on? It needs to be on for it to be found. (That confused me the first time I used one -- just two days ago.) I use the supplied cable to connect to the PC. I just tried bluetooth and it didn't connect; but I did not see any pairing so am hardly surprised. (EDIT: Just found that the CMS50F shows up on the list of bluetooth devices without my having had to do anything. Doesn't matter, though, as I cannot get a bluetooth connection to the meter.)

The current version of SpO2 assistant is 3.0.5.

RE: Pulse Oximeter Contec CMS50F
Somebody else posted a picture of a new CMS50F wiht v2.0 hardware and his version of SpO2 Assistant was greater than v3.05. His new version of SpO2 Assistant (has a new name!) was able to read his CMS50F and create a file that OSCAR could read. OSCAR cannot yet read the new Version 2 hardware.

The CMS50F has the serial to USB chip with in the watch unit, so any USB cable with the right size connector will work. The Version 1 hardware uses a mini-USB, I think the version 2 does also.

For better or worse, my three-day-old CMS50F has a date of 2019-03 and a serial number beginning with 19. I guess the first two digits are how to identify the version?

In any event, I can import from the CMS50F directly into OSCAR without any problems, using the USB connection. It all came together flawlessly. I guess I was lucky and didn't get the new, improved version!

I think the new versions are coming straight out of China. I'm not sure that Supplier #19 has them yet
