If you see the error message below when trying to open the barcode software on the Plate Reader or Specimen Reception PCs, this is simple to resolve.

  2. Expand the Ports section by clicking the small arrow next to it and make a note of the COM number as shown below in red (this number may differ on different PCs)

  4. Click OK and the software will connect as normal to the scanner
