# LiDAR UTC Time Synchronization
|
||
|
||
LiDAR UTC time synchronization demo shows how to synchronize time data (GPRMC/GNRMC) from serial port to Livox LiDAR.
|
||
|
||
## 1. Set Serial Port Name
|
||
|
||
Serial port name indicates where to read time data. Serial port name is set to : (1) `COM3` on Windows; (2) `/dev/ttyUSB0` on Linux by default. you can call `SetPortName (std::string port_name)` to set your synchronizer's serial port name.
|
||
|
||
## 2. Set Baud Rate
|
||
|
||
Baud rate is set to `BR9600` (9600) by default，you can call `SetBaudRate (BaudRate baudrate)` to set baud rate：
|
||
|
||
| BaudRate |
|
||
| --------- |
|
||
| BR2400 |
|
||
| BR4800 |
|
||
| BR9600 |
|
||
| BR19200 |
|
||
| BR38400 |
|
||
| BR57600 |
|
||
| BR115200 |
|
||
| BR230400 |
|
||
| BR460800 |
|
||
| BR500000 |
|
||
| BR576000 |
|
||
| BR921600 |
|
||
| BR1152000 |
|
||
| BR1500000 |
|
||
| BR2000000 |
|
||
| BR2500000 |
|
||
| BR3000000 |
|
||
| BR3500000 |
|
||
| BR4000000 |
|
||
|
||
## 3. Set Parity
|
||
|
||
Parity is set to `P_8N1`(No parity) by default，you can call `SetParity(Parity parity)` to set parity :
|
||
|
||
| Parity |
|
||
| ------------------------------------------------------------ |
|
||
| P_8N1 /* No parity (8N1) */ |
|
||
| P_7E1 /* Even parity (7E1)*/ |
|
||
| P_7O1 /* Odd parity (7O1) */ |
|
||
| P_7S1 /* Space parity is setup the same as no parity (7S1) */ |
|
||
|
||
**Note**
|
||
|
||
Livox-SDK release version <= 2.0.0 doesn't support to synchronize Mid40. It will be fix in next release.
|
||
|
||
Or you can refer to [Mid40's UTC synchronization](https://github.com/Livox-SDK/Livox-SDK/issues/31) to resolve the problem temporarily.
