Data Output Format:
When it sensors the card, the serial number will be output via Data 0, Data 1 two data wire
Data 0 and Data 1 are high level when there is no data output
Logic Definition:
Data Bit 0: it will generate 200us low level on Data 0 wire.
Data Bit 1: it will generate 200us low level on Data 1 wire.
Every data length is 2200us.
Every Mifare card has a serial number with 4 bytes, users should output the last three bytes.
Add the first 12-bit even check bit in the front and add the last 12-bit odd check bit in the back, 26-bit data in total.
For Example:
Card number is 6B 3D 12 D6
Output data is 3D 12 D6
Wiegand26 Encode:
| 0 | 00111101 | 00010010 | 11010110 | 1 |
| Even Check | 3D | 12 | D6 | Odd Check |
Notice:
1). Wiegand interface belongs to short distance transmission interface, its connection distance should be no longer than 100m.
Under complex circumstances, please use shielded wire.
2). Card reader belongs to RF series product, please keep it away from interference source.
3). Please use it in safe conditions.
