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
