Yes old topic. But wanted to comment on last post in case somebody runs across this thread in future as these meters and the over priced cables are still being sold.
I ordered both cables mentioned in previous post. Got the serial data cable today. Tried plugging it into computer serial port directly. Yea I have an old computer! Software couldnt find meter. I assume this latest version of software only looks for usb ports??? Or converter cable chipset??
The serial to usb converter cable is on its way via slow boat from China so try again then. It has the PL2303 chip so assume it mimics actual serial port rather than the HID port mentioned.
This is only webpage where I found the suggestion of serial data cable + converter cable mentioned. And I think its great suggestion if it still works. Hate to think how many people been ripped off buying either the way overpriced official OneTouch cable or the somewhat overpriced knockoff cable now available several places on Amazon.
can anyone update me the output voltage of nellcor sensor prode ds100a? i cant find any data sheet out there.
I am working on this project right now... for nellcor ds 100 finger tip... or spo2 sensor... as you can see leds are connected in serial way like two 9v batteries +to - and - to + so you need a H bridge to switch polarities in order to light infrared and up and then switch again and light red only and repeat the process... see my video located at https://www.youtube.com/watch?v=wfevijjX_ig hope it helps..
