let´s say: Different 
I can´t figure out how to get the dec number when using wiegand mode. Now with the new Code I get new results:
Dongle 1
Aufschrift 0001217496
Scan with UART 01001293D858
Convert Hex to DEC Hex: 1293D8 --> DEC: 1217496

Dongle 2

Dongle 5
Aufschrift 0014594826
Scan with UART 2900DEB30A4E
Convert Hex to DEC Hex:DEB30A --> DEC: 14594826
Scan W26 00000000100001010011001111
Scan W26 new 00010000101001100111101010
But still have no idea how to convert to the Dec number printed on the dongles.
Also i don´t know if the wiegand string is correct, as i think with the parity bits it´s the other way arround as shown in the manual.
1111011010110 1100001001110 9 6
1111011010110 1100001100101 9 6
0001100100101 1011000100110 5 6
0001100100101 1010110000000 5 4
0001000010100 1100111101010 3 8
If i understand that correctly, then my parity bits are the opposite and that would mean corrupt data.
