List of common issues when using a Q.station or Q.monixx controller and how to resolve them
Network scan cannot find the controller
Network scan cannot find the controller
If you cannot find your controller with a network scan, we recommend starting with the following troubleshooting steps:
- Is the controller ON? (just checking 😜)
- Is the controller connected correctly to the PC via Ethernet? An Ethernet crossover cable is not needed. Replace the cable when in doubt.
- 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.
- Make sure that the PC's LAN adapter has IPv6 enabled.
- 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.
- 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).
- 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.
- Is it possible to ping the controller's IP address?
- 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
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:
- lower the amount of data on the UART (fewer modules or variables)
- lower the sample rate of the variables on the UART
- Increase the baud rate of UART, if possible
