3.1.9 Error Messages
If for some reason, the communication or instruction did
not take place an error message will appear in the text
box on the top of the GUI, or an error message panel will
tell the user the proper actions to take. It is always a
good idea to update the GUI after an error has occurred
to prevent the board from differing from the GUI in any
way. This maybe accomplished by hitting either the
READ IXDP610 STATUS button or by hitting the RESET
button (the current settings will be lost if RESET is
used). Hit the close button on any error panels to close
the panel.
