== Problems with USB to serial adpaters ==

Problem: The used computer does not have a serial port and we use an  O2k Series A to D, therefore a USB to serial converter has to be used.  However, [[DatLab]] is not able to connect with the O2k.

To find out the exact location of the problem:

- use the Windows device manager to find the correct COM port attached to the USB to serial converter. If you can not find this com port:
* the driver for the USB to serial converter has not been installed on the computer. Install from an CD coming with the converter or from the Internet. Check that the USB to serial converter and the attached Com port are now visible in the Windows device manager
* there is a  hardware problem with the connection - try to manually disconnect and  connect the cables again until you can see the com port attached to a  USB to serial connector again. Some USB to serial converters have a  rubber rim actually pushing the cable out of the connection. This can be  solved by removing the rubber rim with a knife.

Once you know the number of the COM port that is attached to the USB to serial converter
* restart DatLab
* select the Com port you have seen in the device manager and try again.
*  You might have to hit the connect button two or three times for the first time connection


If  everything fails, please use a different computer to try to connect so  that we can exclude any problems on the oxygraph side.
