Pin No. Name Function
1 VCC 5V
2 GND Ground
4 ANT No Use
5 ANT No Use
6 SEL HIGH selects RS232, LOW selects WEIGAND
7 TX UART TX, When RS232 is Selected
8 D1 WIEGAND Data 1
9 D0 WIEGAND Data 0

RS232 interface format

10 ASCII DATA (card no.)+ 2 ASCII DATA (XOR result)

E.g. Card number is 4500C5D1E9B8 read from reader then the card number on card will be as below.

45 - Preamble

00C5D1E9 value in Hex = 12964329. / B8 is XOR value for (45 XOR 00 XOR C5 XOR D1 XOR E9)

Hence number on the card is 0012964329.

1. Data baud rate: 9600 bps
2. Data bit 8 bits
3. Parity check: None
4. Stop bit
