In the XLights4 software I added a USB device to the Setup Tab and set the output to run on OPEN DMX and set the output to Comm Port 9. I then created a simple sequence using instructions in a video by Clyde at Leechburg Lights on YouTube... (search for the video "Getting Started with Xlights/Nutcracker 4.0 software". He has a lot of videos on this).
To connect this to a controller, I wired up as follows:
Adapter (A+) to the (DMX +) on the controller.
Adapter (B-) to the (DMX -) on the controller.
After creating a simple sequence, I selected the "output to lights" icon at the top of the XLights4 Sequencing software. When I did this, a GREEN LED began to flash on the adapter. When I applied power to the RGB controller, the controller's on-board LED began to flash and was receiving DMX signal from the computer. I connected several sets of RGBs to the controller and played the sequence. Everything played as it should have. Very happy with the purchase. I will be testing this through the year to insure that it will work for my needs in programming my light show.
My laptop is running Windows 7 64-bit (haven't tested this on a Linux machine) and with an internet connection it installed the driver automatically when I connected it to a USB 2.0 port.
I have not tried daisy chaining devices to add more than one to my Modbus network. Because it's only two wire, I wouldn't recommend using this for a Modbus master application that has numerous slave devices which are spaced out by any sort of distance. I would opt for something a little more industrial that has a terminal block for a signal ground reference wire in that instance, but you'll end up paying more for that. If all you're looking to do is the local quick and dirty scan, connect, configure, and poll for 2-wire RS485 at an economic price point, this adapter is just the thing. I've recommended it to many of my colleagues and they have all had great success with it also.
I did not test under Windows. Windows 7 does not have a default driver, so you must download some shady exe file from a craptastic chinese website. No thanks. I'm going to stick with the FTDI device instead. It works great under Linux and Windows.
