1. Wiegand Card Formats Configuration of proximity cards

2. Facility Code – Same On All Cards Card Number – Different On All Cards Parity – Usually First And Last Bit All Binary Data (Contains Only 1’s And 0’s) Transmitted On Two Wires (Data 1 and Data 0) Total Number Of Bits Is Very Important

7. TOTAL NUMBER OF BITS EVEN / ODD PARITY BITS FACILITY CODE START / COUNT CARD NUMBER START / COUNT

8. 26 BIT TOTAL LENGTH 13 BIT EVEN / 13 BIT ODD PARITY FACILITY CODE BITS 2 – 9 (8 BIT) FACILITY CODE RANGE 000-255 CARD NUMBER BITS 10 – 25 (16 BIT) CARD NUMBER RANGE 00000 - 65535
