Data transmission format:
for cards
| STX (Start String) | Card Data | Checksum¹ | ETX (End String) |
| 1 byte 0x55HEX | 4 bytes HEX | 1 bytes HEX | 1 byte 0xAAHEX |
¹Checksum = XOR Card Data
For iButton keys
| STX (Start String) | iButton Data | Checksum² | ETX (End String) |
| 1 byte 0x51HEX | 6 bytes HEX | 1 bytes HEX | 1 byte 0xAAHEX |
²Checksum = XOR iButton Data
Data transmission protocol: 9,600 baud rate, 10 bits, parity bits – none, 8 bits of information,
one start bit, one stop bit.
