    Anybody familiar with a communication error in xlights.


    When I try to turn on the lights for testing, I get a communication error, stating....

    Error occurred while connecting to OpenDMX network on COM3 (available ports: error 2 (can't get serial comm ports from registry))

    Things to check:
    1. Are all required cables plugged in?
    2. Is there another program running that is accessing the port (like the LOR Control Panel)? If, so then you must close the other program and then restart xLights.
    3. If this is a USB dongle, are the FTDI Virtual COM Port drivers loaded?

    unable to open serial port, error code=-1
    Proceed anyway?



    It is a USB dongle and the drivers are updated, cables are plugged in and I don't think there is another program running that is accessing the port.


    I can get the lights to work using Vixen and Da DMX.


    Any ideas.

    When you open windows control panel and have a look at the serial ports does it show the dongle as being a virtual serial port on comm 3? I haven't tried it with xlights yet but LOR was particular with which port the dongle was plugged into as changing the port changed the comm port that it would appear as.
