Software Questions

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

  1. Please check if you are using the USB data cable, not the Power cable. The correct USB data cable should have a bulky end that plugs into the PC and should be labeled with “USB”. The USB data cable is included with every PC-66H and PC-66L unit.
  2. If you are using the correct USB data cable, but still getting COM error. 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 prompt, and check Device Manager when finished installation.








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 time when you perform data upload in the software. You will need to finish all uploading process, including data selection and uploading to the patient record, while the device data upload screen is ON.
