Wiegand input format description:

Wiegand protocol provides 2 lines for data transfer. A pulsed transition on the DATA1 line indicates a logic
1 bit, while a pulsed transition on the DATA0 line indicates a logic 0 bit. In their idle state both lines are
held high. During data transfer the appropriate logic line will pulse low for 50uS followed by a period of
2ms where both lines are held high. In this fashion each bit is transmitted in sequence until all bits are sent.
The end of the transmission is signaled by both lines being held high for more than 50mS. Figure 1
shows an example of the timing sequence for Wiegand protocol.

Wiegand 26 input format description:

Wiegand 26 protocol is defined as a stream of 26 bits, consisting of 1 Even parity bit, 24 data bits, and 1 Odd parity bit.

Wiegand 34 input format description:

Wiegand 34 protocol is defined as a stream of 34 bits, consisting of 1 Even parity bit, 32 data bits, and 1 Odd parity bit.

wiegand 37 bit protocol description

Wiegand 37 input format description:

Wiegand 37 protocol is defined as a stream of 37 bits, consisting of 1 Even parity bit, 35 data bits, and 1 Odd parity bit.

Tecom 27 format description:

Tecom 27 protocol is defined as a stream of 27 bits. It is made up of 11 bits for Site Code, and 16 bits for Card Number. The various bits are interspersed through the input stream and are re-arranged into Site Code and Card Number segments on Output.

Bit	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25	26	27
Type	C	C	S	S	C	C	S	C	C	C	S	C	C	C	S	S	C	C	S	S	C	C	S	S	S	C	C
Bit No.	1	2	11	10	15	16	7	12	13	5	8	14	4	3	9	1	8	9	6	2	7	10	5	4	3	11	6

Note: C : Card Number (16 bits) S: Site code (11 bits)

SC = 16,20,25,24,23,19,7,11,15,4, 3

CN = 1, 2, 14,13,10,27,21,17,18,22,26,8, 9,12,5, 6

Eg.
The Input data stream 004217E8   in hex

Resolves to Site code = 010 1010 0100     2A4 (hex) = 676 decimal
And Card Number = 0000 1011 1100 0010   BC2 (hex)   3010 decimal

The WIE232-A, WIEG4PRT-A and WIEG8PRT-A will read signals presented in Wiegand data and will convert the data stream to a serial RS232 output on the corresponding output connector.
