3 . Communication details:
3.1 Network receiving
The ASCII code between 0X30---0X39 is required, and the maximum number of bytes input
is 20 bytes; (or 1 byte hexadecimal code)
The time interval between byte and byte is within 25ms. If it exceeds 25ms, data will be
processed. Then it is sent with Wiegand 34bit, if the serial port only receives one byte of data,
it will be considered as a keyboard Data will be sent in Wigan 8bit
For example: After receiving 31 32 33 34 37 38, the serial port will convert these bytes of
data into 16 The base is sent in Wiegand 34bit: 0001E256
Detailed explanation: Wiegand 34bit can send a maximum of 4 bytes of hexadecimal
code, which means that the serial port input The largest number of data in hexadecimal is
FFFFFFFF, which is 4294967295 in decimal (a total of 10 bits, it means there are 10 bytes in
ascii code), so the data value input by the serial port should be in
Between 0---4294967295.
The maximum number of bytes input by this converter is 20 bytes. If it exceeds Wiegand
after being combined into hexadecimal 34bit output standard, the excess part will be
intercepted and sent
For example:
the data (ASCII code) received by the serial port is 31 32 33 34 35 36 37 38 39
