## Application
- Smart AC Socket Outlet With wire control of RS485
- Smart AC Socket Outlet With wire control of RS485
## ACSocket Modbus RTU Protocol
### Description:
- 1. Communication uses RS485, 1 bit start bit + 8 bit data bit + 1 bit end bit
- 2. Baud rate 9600
- 3.Device ID defaults to AAH
- 4. Address 00H is the broadcast address, the slave does not reply
### Instruction: (hexadecimal) (Modbus RTU format)
### 1. Write coil
The host sends:
`AA 05 00 00 FF 00 95 E1` (closed coil)
`AA 05 00 00 00 00 D4 11` (disconnect coil)
