- 5VDC through USB (External 5V supply will boost range of the module)
RS232 interface format
- 10 ASCII DATA (card no.)+ 2 ASCII DATA (XOR result)
- E.g. Card number is 4500C5D1E9B8 read from reader then the card number on card will be as below.
- 45 – Preamble
- 00C5D1E9 value in Hex = 12964329. / B8 is XOR value for (45 XOR 00 XOR C5 XOR D1 XOR E9)
Hence number on the card is 0012964329.
- Data baud rate: 9600 bps
- Data bit 8 bits
- Parity check: None
