DC 9V To 12V 40mA 7941D Dual Frequency Card Reader Wiegand 26 / 34 And UART Interface

Parameter: Voltage: DC 9V to 12V Current: 40mA Support: 125kHz and 13.56mHz (iso14443A) cards Interface: wiegand, UART Size: 47*26*5mm (length*width*height, including antenna) Environment: 20 to 70 EM4100 reading distance > 8cm Mifare S50S70, defire, FM1208 reading distance > 5cm Interface description: D1D0: wiegand data output Data 1, Data 0 FOR: format selection (hanging for W26, grounding for W34) Wiegand interface output description: When a card is sensed, the serial number of the card will be output through two micro-measure lines: Data 0 and Data l; When Dato 0 and Data l are output without microprocessing, the part is off-level; Micro-bit 0 generates a low level of 400u on the Data 0 line. Microdata bit 1 generates a low level of 400u on the Data l line; The length of each document is 2400us; Each mifere card department has a serial number of 4 bytes per year, and we output it followed by three bytes; In the front plus the first 12 check digits, followed by 12 odd parity digits, a total of 26 data; The card number is: 6E 3D12 D6 Number of outputs donated: 3D12D5 Use: Attendance fingerprint reader module, access control intercom reader module Package included: 1 X 7941D dual frequency card reader module 1 X 5PIN wire
