FAQ

Since Apple made us use their sandboxing technology, we have to put the settings in a different location. If you want your settings back, you can copy the xml file from /Users/yourname/Library/Application Support/JVLightning DMX Control/ to /Users/yourname/Library/Containers/nl.jv.LightningDmxControlLite/Data/Library/Application Support/JV Lightning DmxControl/
Please replace 'yourname' with your username.
We apologize for the inconvenience, but sandboxing is a good thing, it will keep your computer safer when a hacker or virus is intruding your system.

Usually the problem is that another application or driver is already claiming the USB device, so Lightning cannot connect to it. Lightning includes the necessary driver files, so you should not have installed anything. Unfortunately I don't support the VCOM driver yet, maybe in the future.
If you run into this problem, you should try to unload the kext file.
open up a terminal and type:
sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext

it'll ask for your root password.

Quit and restart Lightning DmxControl. It should work now
If you want do remove the FTDI driver permanently, use:
sudo rm -rf /System/Library/Extensions/FTDIUSBSerialDriver.kext

If you dont have a root password or you don't know it, you could remove it through the Finder by going to System->Library->Extensions and then remove the FTDIUSBSerialDriver.kext

If you didn't use kextunload, you have to reboot your computer.
Caution! If you use the Enttec device for other applications, you might consider moving the .kext file to another location instead of deleting it.

Possible causes:

• There is no network device available.
  
  • iPhone: check if your WiFi connection is active.
  • Mac/OSX:
    Check if your Wifi or Ethernet connection is active. Open Network preferences by clicking the WiFi icon in the top right corner and choose Network Preferences.
  
  
• Another application or service uses port 6454.
  
  • iPhone:
    Doubleclick the Home button and shut down all still running apps by press-and-holding the first button for 2 seconds and then clicking the little red balls on the icon.
    Start ArtnetDmxRemote again and check if the error disappeared.
  • OSX/Mac:
    Open a terminal window and execute the next line:
    lsof -i -P | grep "6454"
    If you are not permitted try:
    sudo lsof -i -P | grep "6454"
    You have to give an admin/root password with the second one.
    
    This will result in a list like below:
    DmxContro 15021 yourusername 7u IPv4 0x7de6dc6d0f1321bb 0t0 UDP *:6454
    DmxContro 15021 yourusername 8u IPv6 0x7de6dc6d07933aeb 0t0 UDP *:6454
    ExampleApp 352 yourusername 19u IPv4 0x7de6dc6cfd53921b 0t0 TCP *: 6454 (LISTEN)
    ExampleApp 352 yourusername 20u IPv6 0x7de6dc6cf9f59c3b 0t0 TCP *: 6454 (LISTEN)
    
    You could conclude from the list above that ExampleApp is using port 6454. Try to completely close ExampleApp and restart DmxControl to check if the error disappeared.
    
    
• Firewall is blocking the application
  
  • iPhone: not applicable
  • Mac/OSX
    Temporarily shutdown the firewall to test if this is indeed the cause of your problem.
    Go to System preferences->Security (CMD-Space and search for 'Security and Privacy')
    Click on the tab 'Firewall' and turn it off. If this is not permitted, try to open the lock in the leftbottom corner of the window.
    Restart DmxControl to check if the error disappeared.
    If this was the cause of your problem, click on Firewall Options and add DmxControl as application and change the setting to 'Allow incoming connections/trafic'.
    Uncheck 'Block all incoming trafic/connections'.
