RFID 125Khz 1356Mhz Embedded ID IC Card Reader Module 1, support the 13.56Mhz and 125khz 2, serial, wigan can switch. Introduction: 125 Khz and 13.56Mhz double-frequency read card module, it integrated high-performance rf card reader to the circuit and antenna, at the same time support wiegand26 wiegand34 and Uart output data protocol. DC 3.3 5.5 V voltage Current 50 ma (most current), standby current: 40 mA Support 125 KHZ and 13.56 MHZ card reads Interface wiegand, UART Small size 47 mm (length) * 26 mm (width) * 5 mm (thickness) (including the antenna) convenient embedding. Industrial-grade products - 40 to + 85 degrees can work normally Interface specifications: 5 v DO D1 / TXD GNDCST The power supply DC 5 v power supply, choose linear power supply can get a better read card effect D1 WG output DATA1 DATA0 DO/TXD Output the WG DATA0 or Uart module this feet for serial data output CSTInduction area has a high level, or other features. Wiegand output interface is introduced: When there is a card induced by that time, the serial number of the card will be sent to you by Data0 and Data1 these two data output.Data0 Data1 in countless output according to the case, for the high level. Data bits on Data0 line produces a width of 100 us low level. Data bits on Data1 line 1 a width of 100 us low level. Each length of 600 - bit data to us Each MF card has a string of four bytes of serial number, we three bytes output of the back.Before adding 12 parity bit, followed after 12 odd parity, a total of 26 data. Card number is: 6b3d12d6 The output data for: 3d 12 D6 Weigand 26 code: 0 00111101, 00010010, 11010110 1 3 d 12 D6 odd parity Weigand 34 code: 0 01101011, 0011110100010010, 11010110 0 6 b3d12d6 odd parity Uart interface output is introduced: Baud rate: 9600 Data length of head card type BCC card data validation data at the end 0 x02 x09 0 0 x01 SNO SN3 besides data end of other data 0 x03 of an exclusive or operation which the card types are: 0 x02 EM4100 0 x01 MF 1 k 0 x03 MF 4 k 0 x20 14443B 0 x61 super SIM card _x000D_
