Wiegand input to USB (analog keyboard) output. The maximum number of digits input by Wiegand is 255. The Wiegand input acquisition speed is fast, with each bit low-level time as low as 30us. The USB output speed is fast and stable. The module can output 5V voltage supplied by the USB interface. This module provides interface source code to support secondary development. Users can upgrade module functions independently. Default shipment function: When the number of Wiegand input digits equals 8n + 2, the first and last check bits are removed, then converted to corresponding decimal or hexadecimal format for USB output. The result can be displayed in a file or notepad. Examples: WG26 input data: AA CC, USB output 10-Decimal: 11189196 (or 16-Hex: AA CC) WG34 input data: AA CC DD, USB output 10-Decimal: 28644397 (or 16-Hex: AA CC DD) When the number of Wiegand input digits is not a multiple of 8 + 2, the data is directly converted to corresponding decimal or hexadecimal format and sent via USB, ending with a new line. Output can be viewed in a text file or notepad. Examples: WG35 input data: 1010 1011 1011 1100 1100 1101 1101 111, USB output Decimal: 22915475183 (or Hex: 555 DE66EF) WG37 input data: 1010 1010 1011 1011 1100 1101 1101 1110 11101, USB output Decimal: 91661900733 (or Hex: 1557799BBD) Color: Black Material: ABS The actual product may have slight color variations, which do not affect functionality.
