USB adapter board
a).Check whether the serial port driver is installed in Device Manager. You can find the driver compressed file in the \rplidar_sdk\tools\cp2102_driver directory, and select the installation file according to your operating system after extraction: 64-bit operating systems use CP210xVCPInstaller_x64 files to install drivers, 32-bit operating systems use CP210xVCPInstaller_x86 files to install drivers.
b).Check whether the serial port adapter board is used correctly, and replace the serial port adapter board for testing.
- Black housing without DIP switch 1000000:S2: 1000000,S3
- No housing, no DIP switch 115200: A1M8
No housing, no DIP switch 460800:C1
- The black housing has DIP switches 115200: A2M8, A2M6
- Black housing with DIP switches 256000: A2M7, A2M12, A3, S1
- Note: A few years ago, the serial port adapter boards were all DIP switches, and the baud rate was 115200.
...
d).Check if there are other serial port tools connected to the Lidar at the same time, and the Lidar cannot be opened by two serial port tools at the same time.
e). Check whether the Lidar serial port line is in good contact, you can remove the bottom cover to see if the serial port line comes off.
f).Overvoltage protection prevents the Lidar from starting, and the supply voltage is between9V and 5.2V. The overvoltage protection values can be tested using the wiring method below.
g).If the above is normal, it means that the serial port of the Lidar circuit board is damaged or broken, it needs to be returned to the factory for repair. RS cannot be connected to a Lidar with a network port accessory board.If the above cannot help to solve the issue, please kindly contact Slamtec for support. If it is necessary, the lidar needs to be sent back for analysis.

board
a)Check whether the IP address of the network port accessory board can be pinged, and if it cannot be pinged, check whether the IP address of the local machine is set to the same network segment. You can also restore to the factory settings by pressing the button, and the button near the Lidar power port can initialize the accessory board, after initialization, you need to reflash the firmware and set up a new IP. Check whether the network port accessory board is used correctly.
- Network port accessory board 115200: A2M8, A2M6
- Network port accessory board 256000: A2M7, A2M12, A3, S1
- Network port accessory board 1000000:S2,S3
- Note: The network port accessory board 115200 and the network port accessory board 256000 can be flashed with the corresponding version of firmware as needed to achieve the general purpose.
...
- Check to see if the power supply is between 9V and 28V.
- Check whether the IP address of the network port accessory board can be pinged, and if it cannot be pinged, check whether the IP address of the local machine is set to the same network segment.
- Early S2E Lidars may first power up the Lidar, and then power up the computer or industrial computer, resulting in the inability to pass the Lidar. In this case, you need to upgrade to the latest firmware.
5.Lidar ROS sdk under Ubuntu 22.04 humble version used abnormally?

After connecting to RS to complete the scan, you can click to download the Lidar data (TXT file format)
11.Can the Lidar USB external wiring exceed 5M?
...
14.“Internal error” occurs during Lidar operation
Plug and unplug the power cord and the USB cable of the USB adapter at the same time. Ensure that the two USBs are plugged and unplugged at the same time (within 3 seconds), and restart to check whether the power supply voltage meets the power requirements.If it is necessary, please kindly contact Slamtec for support.
15.There is no data on the Lidar under the Linux system
1.If it is a Linux system, check to see if the USB is authorized.
Check whether the USB is authorized (if the virtual machine needs to restart the serial port accessory board, select Connect to the virtual machine): ls -l /dev |grep ttyUSB
Licensed USB: sudo chmod 666/dev/ttyUSB0
2.Download and compile SDK from the official website. If there is still no data to check whether the local ROS is successfully installed, use the baby turtle to check whether the installation is successful.
3.Re-download and compile the ROS feature pack.
