4.3.4.3.2 Checksum
48
The dialog allows to automatically calculate checksums of the data in buffers. Since there are several
more or less standard algorithms for the checksum calculation the dialog enables you to set one
standard algorithm or to create some custom, complex algorithms by using a script.

Description
By checking this radio button you set incrementing the serial
number by the fixed value specified here, for example: 1, 2, 10, etc.
result of executing some script file, which can be put in the box
here.
By checking this box you begin automatically calculating the
checksum in accordance to other settings below and to write it to a
specified location in the chosen sub-layer.
The Start and End addresses define the range of buffer addresses
for which the program calculates the checksum.
One of two toggled radio buttons. If checked, one of the preset
algorithms of the checksum calculation can be picked from the drop-
down list.
This radio button sets an alternative method of the checksum
calculation by means of a custom made script.
These radio buttons allow the selection of the checksum size: one,
two or four bytes.
These radio buttons allow the application of some operation to the
raw result of the data summation: Negate, Compliment or do not
apply any operation.
These radio buttons allow to select the source data size: one, two or
four bytes
These two toggled radio buttons define an order of bytes that
represent the checksum - either the least significant byte (LSB)
follows the most significant byte (MSB) or vice versa.
By checking this radio button you specify the increment value as a
