Do not use master mode on your lights as in most cases that dusables the dmx control that you are wanting. The dmx controller is output and your lights should have dmx in and a dmx out to next light. Also, make sure that the lights you have are dmx lights and not master/slave. You should have ether a dip switch or digital display to set the dmx channel. If you do not have ether then you will need a dmx switchpack to control the light with dmx. Hope this is helpful. **Q: How many lights will this control and what is a free software that does not require a license to use it?** A: It gives one universe of 512 channels. Depending on the number of channels each fixture takes will tell you how many units can be controlled. If you have a dimmer rack with one channel per light then you can control up to 512. If each unit takes up 13 channels you can have 39 fixtures plus a few channels left over. It won't work with Hog or MA but can probably work with the M-PC and other PC lighting consoles. The website has a list of compatible programs. Some of them are free. **Q: Is this compatible with the dmxis software?** A: This products is compatible with other open sourced pieces of software. Not Compatible with DMXIS, that is a closed sourced interface, and software. DMXIS Interface works with DMXIS software only. **Q: What is the max refresh rate?** A: Hello, Max output refresh rate is 40FPS² Regards ## Frequently Bought Together - Enttec Open DMX USB 70303 Lighting Interface - Open Source/Hardware Only - Entry Level Model - Cable Matters 2-Pack 5 Pin to 3 Pin DMX Lighting Cable - 6 Inches, 5Pin Male to 3Pin Female XLR/DMX Adapter Cable, Black - SiYear XLR Male 3 Pin to XLR Female 5 Pin & Female 3 Pin to Male 5 Pin Audio Cable, for Microphone DMX Stage Light Turnaround Etc（1Set / 2Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/766396318-open-dmx-usb-70303-pc-dmx-interface](https://www.desertcart.com.br/products/766396318-open-dmx-usb-70303-pc-dmx-interface) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-06-08*
