“Error saving fi le”
This error message is shown if the KEUSB24.EXE program
attempts to save a fi le 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 fi le 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 confi guration to a fi le or to the KEUSB24. Check
the matrix confi guration and eliminate redudant pin letters.
The error message will give the letter of the problematic pin
(Example: “Error: Pin D is used for multiple scan lines”).
