CT_Trip_Info.txt

# Explanation: Trip codes are separated by blank lines.  First line after a blank line is the displayed characters on the drive, and can be used as a shorthand for the Trip.  The next line is one or more numerical codes (separated by commas), which would be found in menu registers #10.20 through #10.29 of the controller.  Any following lines starting with * are hints about what to check regarding the Trip.
