EXAMPLE
N1 == 1234 == 4D2 hex
N2 == 56789 == 162E hex
CheckNumber == 2951 == B87 hex
Line1 == 4D2 + 162E
== 1B00
Line2 == 162E + 162E * 2 == 428A
Line3 == 1B00 + 428A == 5D8A
Line4 == 4D2 + 4D2 == 9A4
Line5 == 5D8A - 9A4 == 53E6
Line6 == 53E6 + DF6 == 61DC
Line7 == 61Dc / 4D2 == 14 == 20 in Decimal
It took only 7 lines to calculate the serial in short mode, let's take it into one formula...
Variant1 == N1 + N2
Variant2 == N2 + N2 * 2
Variant3 == Variant1 + Variant 2
Variant4 == N1 + N1
Variant5 == Variant3 - Variant 4
Variant6 == Variant 5 + DF6
Variant7 == Variant7 / N1
Serial Variant7 in DECIMAL !!!!
