Description 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
