When I try to upload data from PC-66 series oximeters – to PC, software say “COM error”?

Please check if you use the USB data cable, not the Power cable. The correct USB data cable should have a bulky end that plugs into the PC and be labeled “USB”. The USB data cable is included with every PC-66H and PC-66L unit.

 

If you are using the correct USB data cable, but still getting COM errors. Please search and run “Device Manager” in the Windows Search. Check if you have Prolific USB-to-Serial Comm Port under Ports, as shown below. 


If not please download and run this USB Driver > choose Repair if prompted > and check Device Manager when the installation has been finished.

 

If you have the Prolific USB-to-Serial Comm Port show up, please make sure you have the device ON with the data upload screen at all times when you perform data upload in the software. While the device data upload screen is ON, you will need to finish all uploading processes, including data selection and uploading to the patient record.
