Hex Digit Binary Byte Field Description
1-4 1,2 Checksum Data This field contains a modulo 65536 checksum. If the sum is 12345678, then it is di-
vided by 65536, and the remainder is output; For example, 12345678 / 65536 =
188.3800964 = 188 + 24910/65536, so the number 24910, converted to hex as 614E
would be output.
An easier way to compute the checksum is using the sum 12345678; converted to
hex it is the number 00BC614E. The least-significant four hex digits are output; i.e.
614E.
