In the body of firmware transceiver there are two checksum that define data integrity of the firmware body. In the tabs FIRMWARE DETAIL and TABLE checksum bytes have addresses 0x3F and 0x5F.
By the default, software automatically recalculates checksum when you changed the firmware in the tables. To disable the automatic checksum verification, deselect flag in menu Options -> Auto set checksum.
To validate the checksum in the current firmware, you must use menu item Edit -> Checksum.
When pushed, the program will compare checksum values and highlight the cells with green if the control sum is correct and red if not.
To set correct checksum value in the body of the firmware, click install checksum:
After pressing the button of setting the checksum there will be a recalculation of all checksums.
