What to do if HOKUYO AUTOMATIC Measuring Instruments UST does not connect with Area Designer?
- C
  carolyn16Aug 4, 2025
  If your HOKUYO AUTOMATIC Measuring Instruments UST does not connect with Area Designer, there might be several reasons: 1. The configuration might be incomplete. Try reconfiguring the UST. 2. There might be an issue with your PC's specifications or other applications. Ensure your PC meets the necessary specifications, close unnecessary applications, and try reconnecting. 3. The power supply could be off. Ensure the power supply is on, the voltage is within the specified range, and the power supply cable is in good condition. 4. The USB cable may not be properly connected. Ensure the USB cable is securely connected to both the PC and the UST. 5. The driver might not be installed. Install the necessary driver.

Why is the output OFF even with no object in the detection area in HOKUYO AUTOMATIC Measuring Instruments?
- R
  Robert WyattAug 18, 2025
  If the output remains OFF even when there is no object in the detection area for your HOKUYO AUTOMATIC Measuring Instruments, consider the following potential causes: * Light interference: Ensure the UST is mounted in a location free from light interference. * Contaminated optical window: Check the optical window for any contamination or damage. * Floor detection: Ensure the floor is not being detected; reconfigure the detection area if needed. * Background detection: Ensure the background is not within the detection area; reconfigure the detection area. * Malfunction state: Verify the power supply LED is not blinking (indicating a normal state). * Hysteresis setting: Reconfirm the hysteresis setting.

  Dustin MirandaAug 27, 2025
  If obstacles are not detected inside the selected detection area with your HOKUYO AUTOMATIC Measuring Instruments, check the following: * Ensure the power supply is providing the correct voltage. * Verify that the UST is not in a malfunction state by checking the power supply LED. Restart the UST if it is blinking. * Confirm that the object width in the detection area is greater than the minimum detectable size configuration.
