Guide to Troubleshooting Connection Issues

If your PC, Cellair Controller, or training device cannot establish a connection, the issue may be caused by one of the following reasons:

1. Checking the LAN connection:

• Ensure that all cable connections are properly connected.
• To check this, look at the switch (hub) and see if the small LED lights are blinking. If necessary, restart the switch.
• Also, check your device to see if the connection LEDs are blinking. If this is the case for all devices, the cabling is likely fine.

2. Checking the DHCP server:

• Ensure that only one device in the network is assigning IP addresses (DHCP server).
• A common issue occurs when devices like notebooks are connected to the home network via a Wi-Fi router, while other devices are connected to the DHCP server port of the Cellair Controller through the switch. This can cause two DHCP servers to be active, leading to connection issues.
• In this case, disconnect the notebook from the Wi-Fi router and connect it directly to the switch using a LAN cable. A restart of the notebook without a Wi-Fi connection is necessary!

3. Restarting all devices:

If the issue persists, restart all devices in the following order:

1. Shut down the controller and turn it back on. Wait until it has fully booted up.
2. Then start your end device (e.g., notebook or PC).
3. Lastly, turn on the training device.

This sequence ensures that the devices can communicate with each other correctly.

4. Deleting the device in the Device Manager of the Cellair Control Software:

If the connection still cannot be established, follow these steps to delete the device in the Cellair Control Software:

1. Go to the Device Manager under "System" -> "Device Manager" and turn off your training device.
2. Click on the trash bin icon to delete the device. This only works if the device has been turned off beforehand.
3. If the deletion does not work on the first attempt, turn off the device, refresh the view using the green Refresh button in the lower-left corner, and try again to delete the device via the trash bin icon.
4. After successfully deleting the device, log out of the software, turn the training device back on, and log back into the software.
5. Return to the Device Manager. If the device is not yet listed as a station, refresh the view again using the button in the lower-left corner. The device should now appear.
6. The connection between your software and the device is now restored, and you can attempt to start a session.

If the issue persists after these steps, more complex solutions are described in another tutorial.
