The card analyzer only works with certain products that we offer. It was designed to work specifically with the pcProx Plus card readers with a USB interface. These models typically end in "AKU ". 

Examples of a model number would be:

RDR-805X1AKU, RDR-800X1AKU. RDR-805X2AKU & RDR-800X2AKU

If you are receiving this error message when trying to run the analyzer, you have an unsupported model connected.  

Please refer to the list of supported readers at the bottom of the error message.
