0xFF Keyboard Data
For example:the data received by serial port tool is 02 0A 02 2E 00 B6 D7 B5 F2 03, then
The first byte 0x02 means data start
The second byte 0x0A means the whole data length is 10 bytes, which includes data start and data end
The third byte 0x02 means the card type is EM4100
The fourth to eighth byte (0x2E 0x00 0xB6 0xD7 0xB5) means the read card number, and the fourth byte 0x2E is hidden card number
The ninth byte 0xF2 means BCC check of second byte to eighth byte
The tenth byte 0x03 means data end
Notice:
Keep away from interference source, and strong interference signal may affect card reading
Select linearity power can improve the card reading distance and effect; switch power may attenuate the distance but will not influence normal operation
The module can operate normally in the range of 3-5V, please do not use higher voltage
This module has high frequency signal, so it may cause some interference to the analog circuit. Uses should place the module a little far away from the buzzer; if the distance is too close, the sound of the buzzer will be low
Applications:
Attendance Fingerprint Read Write Module
Entrance Guard Intercom Read Write Module
Replicator
Attendance fingerprint card reader module
Entrance guard intercom card reader module
