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 cc, USB output 10-Decimal: 11189196 (or 16-Hex AA CC ) WG34 input data volume AA CC dd, USB output 10-Decimal: 28644397 (or 16-Hex AA CC DD ) 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 new 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 (or Hex 555 de66ef ) WG37 input data: 1010 1010 1011 1011 1100 1100 1101 1101 11101 USB output Decimal: 9166 1900 733 (or Hex 1557799 BBD ) Colour:black Material:ABS The actual product may have slight color difference or difference, which not affect the use Package Contents: 1 x Wiegand To USB Converter Only the above package content, other products are not included.
