This only has one dmx out. how does this control multiple lights that will be working master mode? i'm using showxpress and new to dmx.

You will set your light to a dmx channel range 1-512. 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.

How many lights will this control and what is a free software that does not require a license to use it?

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.

Is this compatible with the dmxis software?

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.

What is the max refresh rate?

Hello, Max output refresh rate is 40FPS² Regards

Reliability for affordability

I outfitted several venues with this unit. Provides reliability and connects easily. Send signal well, we use Lightkey. Never have issues with it. Small and easy to hide in setups.

Great for small club

Used this for an eight-light DMX setup in my small dueling piano club. After some research into the right DMX software, setup was a breeze. No problems after a solid month of use. Very pleased with the value.

Great product.

This little converter saved my life. I thought I would need the pro version, but this was fine. I’m using it to communicate with a DMX splitter to access a DMX controller that already has a DMX console hooked up to it.

Worked perfectly till about January this year.

It worked great but then it would flicker all my lights and I stopped using it. I decided to open it today that I was free and it looks like a component burned. Didn’t even last a whole year. I would buy again if they fixed this issue tho

Good enough :)

It's a good product for that price. I'm a mac user and works perfect.You have to be careful and read the product specs before purchase it. In my case, the only "con" is that this interface is not supported by MadMapper or Resolume Arena, the two pieces of software I use the most. Luckily, I found LightKey 2, a pretty cool, intuitive software to control your lights and works perfect with the OpenDMX USB.I'm pretty satisfied with the purchase.
