Common controller errors and mitigation

List of common issues when using a Q.station or Q.monixx controller and how to resolve them

Network scan cannot find the controller 

Base communication time error

Network scan cannot find the controller 

If you cannot find your controller with a network scan, we recommend starting with the following troubleshooting steps:

  1. Is the controller ON? (just checking 😜)
  2. Is the controller connected correctly to the PC via Ethernet? An Ethernet crossover cable is not needed. Replace the cable when in doubt.
  3. Is the green LED ON (not blinking)? If the LEDs are blinking: what sequence? Check the Q.series XL Manual for more details about the LED error codes.
  4. Make sure that the PC's LAN adapter has IPv6 enabled.
  5. Open GI.monitor from the GI.service user interface in the system tray and click Search, check if the controller shows up in the IPv6 Multicast tab. 
  6. What is the IP setting of your LAN adapter? If the connection to the controller is 1:1, the PC needs a static IP address (the factory default IP address of the controller is 192.168.1.18).
  7. Is there any firewall installed and running on the PC? If yes, deactivate it. Also, deactivate any antivirus software that may interfere. See also ports and libraries required for running GI.bench.
  8. Is it possible to ping the controller's IP address?
  9. Contact Gantner Instruments support with the following information:
    • Type of controller
    • Controller firmware version
    • Results from the above-mentioned troubleshooting steps

Base communication time error

Base communication time error

The error that the base communication time needs to be lower than 90% means that the amount of  one or more of the following needs to be modified:

  1. lower the amount of data on the UART (fewer modules or variables)
  2. lower the sample rate of the variables on the UART
  3. Increase the baud rate of UART, if possible

Q.monixx UART baud rate error with value

Issue: When adding an additional Q.bloxx module to the Q.monixx, you receive an "Error with value - no possible settings available" message.

Cause: This error is caused by an incorrect baud rate setting for the UART. The baud rate of 115200 bps (115k2) is not supported by the Q.bloxx modules.

Solution: Change the UART baud rate to 230400 bps (230k4).
