“Error saving file”
This error message is shown if the KE-USBMX20.EXE program
attempts to save a file that is already open in another application,
or if there is not enough disk space. If this happens, close the
other application and try saving the file again.
“Error: Pin * is used for multiple scan lines”
If a header pin is used to designate more than one row or
column or is used for both a row and a column, this error will
be displayed when saving the configuration to a file or to the
KE-USBMX20. Check the matrix configuration and eliminate
redudant pin letters. The error message will give the letter of the
duplicate pin.
(Example: “Error: Pin 5 is used for multiple scan lines”)
