    Hi,
    after getting the prototypes working (I dont know why but the ready to use bricks of max485 are not working, the bare ones do) I like to attach the gateway via ethernet to my controller. I am using the Arduino Ethernet Shield v1 from HanRun HR911105A 16/02.
    Unfortunately I dont get any ethernet connection.
    This is how I modified my code. Any ideas what went wrong?

    Appreciate any suggestions...

    Thanks kduino

      @kduino the debug output will probably provide useful information.
