![]() Of course any of the 512 channels can and will change in any subsequent frame so an implicit delay of at least one frame is unavoidable. Each of the 512 addresses need to be examined at every frame and depending on the percentage output selected, ideally this would also have 256 states, and each frame would have its HEX number changed downward as needed.ĭo you think that such a stand-alone device could be made to work using an Arduino? In essence this device has an RS485 input and output, a potentiometer as a dimmer and that's it. The balanced RS485 signal I need to adapt leaves the existing controller and would enter the device I wish to build. Each pulse is thus about 4 micro-seconds. ![]() this means that the effective clock rate is 250Khz. Each frame is re-transmitted about 44 times per second. I would like to add this capability and wonder if an Arduino could do this.Īs you probably know DMX512 can control up to 512 different addresses each having from 0 to 255 states per channel. One of my controllers has no master fader facility.
