Data output(Weignad 26）

ı WHen reading card, card no. Will be sent out by D0 and D1

ı If withiout data output, all is VOH

ı Data 0, there is VOL with 400 us width on D0 line

ı Data1, there is VOL with 400 us width on D1 line

ı Each data's length: 2400us

ı Each EM4 card has 5 bytes's card no., reader will send the last 3 bytes.

ı Add 12 bits' even parity and 12 Bits' odd parity, totaly 26 bits.

ı Card no. : 6B 3D 12 D6

ı Data output： 3D 12 D6

ı Weigand26 codeing：

0                 00111101 00010010 11010110 1

Even parity 3D            12             D6             Odd parity
