The dataplate will reflect the base part number of the computer. However, next to the dash number, the words "MOD TO DASH NO. AT TOP" are on the dataplate. Therefore, you must reference the window on the top of the unit to see what the true version or part number of the unit may be. In this example, the base part number is 622-5796-199 while the 634-3076-008 configuration module makes the unit P/N 622-5796-008 which is a Beechcraft King Air 200 version.
