You can find the compressed driver file in the \rplidar_sdk\tools\cp2102_driver directory. After decompressing the compressed driver file, select the installation file based on your operating system: For 64-bit oss, use the CP210xVCPInstaller_x64 file to install the driver. For 32-bit oss, use the CP210xVCPInstaller_x86 file to install the driver.
the black cover without dip switch:S2:1000000
no dip switch without cover 115200:A1M8
the black cover with dip switch 115200:A2M8、A2M6
the black cover with dip switch 256000:A2M7、A2M12、A3、S1
Note: A few years ago, the serial port converter board had no dip switch and the baud rate was 115200.

Note: Different boards can be brushed with the corresponding firmware versions to achieve common purposes.
Ethernet port attached board of A series:
Ethernet port attached board of S2:
1、Check if the USB power cable is properly connected to the USB communication cable. Check if the USB port is normal. Replace the USB port.
2、Check if the USB power supply is stable. Do not use the USB dock for power supply because the quality of the USB dock cannot be guaranteed.
3、Directly connect the two USB devices of the lidar to the computer at the same time (within 3 seconds), and check whether the data is normal using the official website studio. Ensure that both USB sticks (within 3 seconds) are plugged in and removed at the same time.
4、Use a 5V 2A cell phone charger to power the lidar separately. Use the official website RS to check whether the data is normal. Ensure that both USB sticks (within 3 seconds) are plugged in and removed at the same time.
1、The motor of A1 does not run, unplug the power cord of the motor, use a multimeter to measure the resistance value of the motor, generally several ohms, if large, that is, the motor is bad, need to replace the motor.
2、The motor of A2, A3 does not run, the three-phase coil on the circuit board is measured. It is generally several ohms. If many coils are bad, they need to be replaced.
3、The motor of S2 does not turn, measure the three-phase coil on the circuit board, generally several ohms, if a lot of that coil is bad, need to be replaced.
1、Check if USB is authorized under Linux system.
Check if the USB is authorized. (If the VM needs to restart the serial port attachment board, select Connect to the VM.):ls -l /dev |grep ttyUSB
Authorized USB :sudo chmod 666 /dev/ttyUSB0
2、Download and compile the SDK from the official website. There is still no data to check if the local ROS installation is successful. Use the small turtle to check if the installation is successful.
3、Re-download and compile the ROS feature pack.
2、Check if the noise is caused by the resonance between chassis and lidar, you can remove the lidar's USB power supply and USB communication cable, shut down other devices, and use the laptop to start the radar separately to check if the sound is normal.
1、Configure sscom according to the following figure. And close the robot studio. Only one tool can open the lidar serial port. If your A1 is powered on with rotation, but A1 stops rotating after you turn on the serial port tool, please directly change the check status of DTR.
2、Start running lidar:A5 F0 02 58 02 0D(The lidar of a few years ago needed to rotate first)
3、Start collecting data:A5 20(The new version of the lidar is activated directly)
4、Stop running lidar:A5 F0 02 00 00 57
5、Stop collecting data:A5 25
1、The customer's network port conversion module is incorrectly used. The A series network port conversion module is on the left, and the S2 network port module is on the right.
Currently, SDK compilation only supports VS2010 and VS2019. Some computers need to close the firewall and anti-virus software before normal compilation.
No, it's a little disturbing. It doesn't affect use.
