The Wiegand preprocessor string for Wiegand Preprocessor 0 (WPP0) would be:
\L050C50828083010
Broken down to each parameter:
\L
; Programming string prefix
05
; There are 5 bytes of data in the programming string
0C5 ; The address in the programming parameter map of WPP0
08
; Defines 8 byte (64 bit buffer) to hold data
28
; Start of facility code bits in 64 bit buffer (0x28)
08
; Defines 8 bit length of facility code data
30
; Start of badge number data in 64 bit buffer (0x30)
10
; Defines 16 bit length of badge data (0x10)
075

Wiegand Binary Format Table - Wedge programming interface
Now we need to tell the Wiegand Preprocessor (WPP0) to process 26 bit streams using the
above criteria.
The number in the upper left corner is 0x75, a hexadecimal number that gives the
starting address of the Format Table. The 24 bit format would start at 0x75.
For example, a 32 bit format would be located at 0x7D
The 26 bit format we are interested in is located at 0x77.
Now that we know the address of the 26 bit format, we will place a 0x02 in that location.
The 0x02 tells the Wedge to use Wiegand Preprocessor #0 (WPP0)
See next page for details on the programming string to set 0x02 at location 0x77
