[Sdcc-user] Wiegand 44 Bits

[Helton M. <hm...@ya...>]

I have a Motorola/Indala SDR-503 Proximitry Reader and tree wiegand 44
bits...so that is they cards give me....

So I did't find any relationship about Custom Wiegand 44 Bits Protocol
with block of bits which Cards and Reader Give me...


The Wiegand Protocol:

Bit 1 - Even Parity over bits 2 to 22
Bit 2 to 9 - OEM cod (0 to 255) ; Bit 2 is MSB
Bits 10 to 21 - Facility code (0 to 4,096); bi 10 is MSB
Bits 22 to 43 - Id Number (0 to 524,287) ; bit 22 is MSB
Bit 44 - Odd Parity over bits 23 to 43.

The Card Bit Block:

Card # 3389 12175

Block : 0 1000010000000000001100 10111110001111 111000 0

10111110001111: 12175


Card # 3389 11542

Block: 0 1000010000000000001100 10110100010110 111000 1

10110100010110 : 11542

Card #2429 06609

Block: 0 1000010000000000001100 01100111010001 111000 1

01100111010001: 06609


I dind't find any relationship with Custom Wiegand 44 Bits Protocol...
So If Anyone now who protocol is this ,and the what is your format send
me please...

A Lottla Thanks to everybody...

Best regards..
