Enttec DMXUSB PRO serial communication issues, device closes

    Apr 15 2013 | 3:31 pm
    Hello all,
    I am having issues with my Enttec DMXUSB PRO device. I am trying to send out a message to multiple lights at once (multiple channels that control the light intensity) but whenever I try to do this I get the following error:
    imp.dmx.usbpro: Serial communication failed imp.dmx.usbpro: Device closed
    Adjusting each channel individually works just fine, however, these bigger messages cause a shutdown. I was wondering if any of you are familiar with this problem and know any solutions.
    Attached are 2 files, 1 is the main receiver and enabler for the DMX device the other one contains sliders for a moving head. If you click the message underneath any of the MH texts multiple times, it'll result in the same error as stated above.
    I am guessing it has something to do with the write and read speed of both MAX and the DMX device. I'm not sure though and even if that is the case I still wouldn't know how to fix this.
    Best regards, Danny

      I'll give this a test with my hardware later and see if I can reproduce the error.

      Changed the "pak" to "pack" which already reduces some of the load.

      Another simple example, changing the first channel on lamp 1 (channel 11) and the same effect channel of lamp 2 (channel 26) results in the same serial communication error.

      Changing the num_channels from 512 to 100 (not using any more at the moment, will be using more later) fixed the problem for now. Will update as soon as I find out more.
