Benewake TFmini Plus Common problem

Benewake TFmini Plus Products here

• Q: During the operation, if the line sequence is connected wrong, will it directly burn out the LiDAR?A: The inverse connection between TX and RX will lead to abnormal data communication, and the inverse connection between power cord and ground wire will directly burn out TFmini Plus.
• Q: During use, is it possible to unplug the junction between the LiDAR and thecable, and pull out the cable to see the line sequence?A: No, the line sequence can be viewed from the external terminal. Pulling the tail wire will cause irreparable damage to the product.
• Q: Is it possible to detect liquids?A: Hello, because TFmini Plus use light as medium of detection, there will be transmission in the detection of liquid, which will seriously affect the ranging performance.
• Q: What is the difference between the measurement of LiDAR at night and day?A: Hello, TFmini Plus can work normally at night (without artificial lights). Because there is no ambient light (sunlight), the performance at night is better than daytime. TFmini Plus is affected by ambient light (sunlight) during the day. The degree of influence is related to the intensity of the ambient light and the signal. The stronger the ambient light, the weaker the Plus signal is, and the worse the performance of the Plus (increased error).
• Q: Do I need to add a protective cover for outdoor applications? Is the light source a laser?A: Hello, TFmini Plus is designed with IP65 rating, and can work normally under normal outdoor conditions. If you need to use it in heavy rain, the protective cover is needed to improve the protection grade. The light source of TFmini Plus is LED.
• Q: Can the output of the module be changed to 8byte in order to convert the serial data into CAN network data?A: TFmini Plus does not support 8bytes output, and software customization is available if required. The hardware interface of PLUS does not support CAN bus. You can purchase a TLL / CAN adapter board on the official website to achieve communication through CAN bus.

• Q: How to solve the problem of crosstalk when using multiple TFmini Plus?

  A: Hello, TFmini Plus will not generate crosstalk unless they are installed opposite. If you need to install TFmini Plus opposite under special conditions, you can set the TFmini Plus to a single trigger mode and stagger the measurement time by frequency modulation to avoid LiDAR Interfere with each other.

• Q: How can the LiDAR be adjusted to a single test?

  A: Hello, achieving a single trigger measurement can be performed in the following ways: Send the command to modify the output frequency, modify the output frequency to 0, and turn on the single trigger measurement switch: 5A 06 03 00 00 63 Send the trigger command: 5A 04 04 63. Each time the command is sent, the TFmini Plus measures it once and outputs the result. Save the configuration instruction: 5A 04 11 6F.

• Q: Will the configuration parameters be written automatically and saved after power off? Is it necessary to send a “Save Settings” command?A: Hello, they won’t be saved automatically, you need to send an instruction for saving. When you only send the modified instructions without saving, the LiDAR will restore its output according to the previous configuration after restarting. Saving is equivalent to writing the modified settings to flash memory. Except for the instruction of switching IIC mode, the instruction can be saved automatically
• Q: How many meters can the serial cable be extended to? How to achieve long-distance communication?A: Hello, the longest distance of cable supported by TTL interface communication is not more than 2m. You can choose an adapter board to achieve long-distance communication through other methods.
  R: Hello, the longest distance of cable supported by TTL interface communication is not more than 1.5m. If a long connection line is required, it is recommended to use the CAN bus for communication. Long-distance communication has been achieved through our company’s CAN adapter board.
