![]() Also regarding ground loop - Isolation circuit is not needed for me as I pan to place the Pi as near to the lights as possible getting the power from the same outlet, and the the ethernet is already Isolated. I made a custom PCB with an ADM485, taking the power supply from the 5V line, and the signal from the TX of the Pi to DI, set the ADM485 to send mode by connecting both DE and RE pins to 5V with a pull up resistor, then soldered a 3 pin XLR directly to the output.Īs I am not receiving data the 120R terminator is not needed on the sender side. If you are into DIY, I have made a fully working artnet to dmx converter with a raspberry pi and OLA, that works nicely with resolume.įor the setup and some schematics see here. (and BTW Enttec shipping policy limits possibility to get one of thous devices in some countries, like for example Russia ) Of course it not suitable for pro level applications, but if I need to drive just few LED PAR in small space to addition for projections, Open DMX controller can be perfect solution.įor me, Resolume USB DMX feature looks a bit useless because it supports only on 2 very specific device You can use all the features and its not crippled in any way. You will notice that occasionally the Resolume logo will appear on the video output and a robotic voice will remind you what software you are using. It's so many devices on market, easy to get one or you can simply build one yourself (DIY) for 10-20$. The download of Resolume 4 will work in demo mode straight away. It's will be nice to have Open DMX supported in Resolume. ![]() Used in the VJacket demo installation at Maker Faire Bay Area 2011. I think Resolume will not work with virtually any cheap USB DMX interfaces, because mostly all of them based on the FTDI 232 (USB to serial converter) + MAX485 (RS485) chip, including EntTec Open DMX USB Resolume Avenue, with effects and textures triggerable from Resolume. Resolume detect Open DMX USB devices as USB PRO (I think it's mean Enttec USB PRO), and even send signal on it (FTDI chip receiving some signals), but the signal not make it to physical DMX output, because Enttec USB PRO have a bit different hardware, unlike Open DMX. I have tried few Open DMX USB device with Arena 5.0.1:
