  • I have got Mango installed and working. (I think) however to add a Modbus Data source I get this.

    Comm configuration error. Check that rxtx DLL or libraries have been correctly installed.

    I appreciate any help anyone may have to help me resolve this issue. I am very new to this level of computer terminology, and manipulation. So I may need further explanation of some terms. Again Thank You in advance for your help.


  • Crucial to getting this to work is knowing what your operating system is and whether it's 64 or 32 bit.

    If you're running on a 32 bit operating system, you can get the files you will need at the RXTX site: http://rxtx.qbang.org/wiki/index.php/Download. If you're running 64 bit, they'll link you over to Mfizz RXTX: http://mfizz.com/oss/rxtx-for-java

    For windows, all you need to do is unzip the download and put rxtxSerial.dll into your /mango home/overrides folder.

    On Linux, it is essentially the same, only with the rxtxSerial.so in the corresponding linux folder. I can't recall at the moment if that is the only step, I think you may have to

    sudo apt-get install librxtx-java
    

    And that's all there is to it!


  • I greatly appreciate your help! I have no errors when trying to create a modbus serial data source now. I placed the files into the correct java folders, however I didn't realize that I needed to place into Mango/overrides.
