Explanations regarding the parameter "Barcode comparison type"

The parameter "Barcode comparison type" is described with the following bits:

Whether a comparison is positive depends on which bit is set (obviously, only one must be
set). The following table shows the individual conditions:

bit 7

bit 6

bit 5

bit 4

bit 3

bit 2

bit 1

bit 0

e1 e0

Bit

Comparison is positive if …

Barcode != RBC

Barcode == RBC

Barcode > RBC

Barcode >= RBC

Barcode < RBC

Barcode <= RBC

RBCn <= Barcode <= RBCn+1

Barcode < RBCn
Barcode > RBCn+1
