OneTouch glucose meter USB interface cable

[wf1g]

Hi,
Can anyone tell me what serial 9 pin pin connections should should connect to the tip, middle connector and shank for the serial cable?
  I bought an original 9 pin D type cable one years ago from Lifescan, but have misplaced it.  I would rather build my own replacement rather than buy a complete new cable and software package.

        3    RXD    received data from meter to computer
   4    RTS    request to send from computer
   6    DSR    data set ready to computer (connected to DTR)
   7    GND    signal ground
   20   DTR    data terminal ready from computer

Thanks for the help.
I will try and make up a cable and see if it works.
Happy new year to all.

Hi Guys,

Interesting stuff above and hope you can help...

Thinking of getting a OneTouch Ultra2 that has the 3.5mm jack plug and can get the cable no problem.

However, I would like to pull the data into my own program using a COM.dll

When connected does the device(One Touch) just send the serial stream automatically on 'RXD' or do you have to 'send' something via 'TXD' to initiate?

Or (as I do not have a schematic of the 9 Pin) is the DSR/DTR somehow connected to the TX line also? (as there is only TX/RX on the 3.5mm plug)


Hope that all makes sense, I'm a noob to this but have managed to get an RFID device working through the serial port, just wondering now about the possiblity of other devices!!!

Thanks for your time/reading.

The connector tip is Rx
the middle connector band is Tx
and the shank is ground.

Hi,

Thanks for that and have managed to bodge together a cable and send/read the info from it so back on track again!
