Attention:
1, Master-slave polling mode(0x1003 Register Bit2 =0) , Release the button 2 In seconds , Key value register automatically resets to zero , After the host sends a read command , Key value The register will also be reset to zero.
2, Active sending mode(0x1003 Register Bit2 =1) , Immediately send key value data and reset the key value register to zero after pressing the button.
3, The host sends a broadcast command (address: 0xFF)when reading key values , only working in master-slave polling mode and key release 2 panel reply within seconds , other panels no reply.
command example: read key value:
| send 1 press return | |||
| not press return | 01 03 10 0B 00 01 F1 08 | read key value | 01 03 00 02 01 01 24 5A |
