Since we know what a “standard 26 bit” format is, we can define the bit functions and their

positions:

P = Parity Bit

F = Facility Code bit

B = Badge number bit

Assuming we know the badge format, we can define bit functions by location.

If you do not know the badge format, then you will have to find the bit pattern in the raw

stream that represents the desired facility code and/or badge number.

The best way to find an expected number is to take the decimal badge number or facility

code and convert it to hexadecimal. Then look for the binary bit pattern in the raw data

represented by the hexadecimal number.

Now we can gather parameters that will be entered into the wedge programming interface.

Notice that these locations will filter out the parity bits.

The facility code bits

start at 0x28 and are

8 bits long

The badge bits

start at 0x30 and are

16 (0x10) bits long
