▶ COMMUNICATION PROTOCOL
The product includes 68 protocol and MODBUS RTU two protocols. The default configuration parameters of the protocol are as follows:
| PROTOCOL | RION 68 PROTOCOL | MODBUS-RTU |
| Address code | 0 | 1 |
| Broadcast address | 255 | 0 |
| Serial port baud rate | 9600 | 9600 |
| Parity bit | No parity | Even parity |
| Serial port start bit | 1 bit | 1 bit |
| Serial port data length | 8 bits | 8 bits |
| Serial port stop bit | 1 bit | 1 bit |
| Output mode | Question and answer | Question and answer |
| Data Format | Data format | Data format |
| Data check method | Checksum | CRC16 |
RION 68 protocol and MODBUS protocol mutual switching method:
Open the serial port debugging assistant, select the baud rate 115200, no parity, stop bit 1, the connection port number, make the host computer send hexadecimal 0xAA regularly for every 10ms. Power on the product and reply "RION" or "MRTU" to indicate that the change to the corresponding protocol is successful. After the switch is successful, the parameters are all the above default parameters.
