Wiegand input to USB (analog keyboard, KEYBOARD) output. The maximum number of digits input by WG (Wiegand) is 255. The input acquisition speed of WG (Wiegand) is fast. Each bit of low level time can be collected as low as 30us. The output speed of 4USB is fast and stable. The module can output 5V voltage.This voltage is provided by USB interface. This module provides interface source code to facilitate secondary development. Users can upgrade module functions by themselves. Default shipment function of this module: When the number of digits input by WG equals 8 times + 2, the two check bits (first and last) are removed and then converted to the corresponding decimal (or hexadecimal) for USB output. Finally, the output can be displayed in the file or notepad. Examples are as follows: WG26 input data is AA BB cc, USB output 10-Decimal: 11189196 newline (or 16-Hex AA BB CC newline) WG34 input data volume AA BB CC dd, USB output 10-Decimal: 28644397 newline (or 16-Hex AA BB CC DD newline) When the number of digits input by WG is not equal to the multiple of 8 + 2, it is directly converted to the corresponding decimal (or hexadecimal) to output by USB, and finally returned for a line. The output can be displayed in the writing file or notepad. Examples are as follows: WG35 input data: 1010 1011 1011 1100 1100 1101 1101 111 USB output Decimal: 22915475183 newline (or Hex 555 de66ef newline) WG37 input data: 1010 1010 1011 1011 1100 1100 1101 1101 11101 USB output Decimal: 9166 1900 733 newline (or Hex 1557799 BBD newline) Colour:black Material:ABS The actual product may have slight color difference or difference, which will not affect the use Different batches may have different appearance label printing, which will not affect the use Package Contents: 4 x Wiegand
