Low Cost USB-DMX interfaces that WORK with LMS
During our testing of LMS we discovered a couple of USB/FTDI/RS485 interfaces that used the correct chipset to enumerate over USB and expose themselves as OpenDMX devices
This was quite a nice discovery, and further testing proved that not only could these be used to OUTPUT to DMX, but also INPUT from DMX
Both devices are available on Amazon
The left hand device is a little obscure in name (and comes as a pack of two), but as long as you purchase this variety it should work without any problems : https://www.amazon.co.uk/dp/B07Z1V5WQS
CONNECTIONS:
"-" -> DMX Ground Pin 1
"A" -> DMX Pin 3
"B" -> DMX pin 2
The Right hand device is made by a decent company called Waveshare, this is their lowest cost version of the USB/RS485 interface (as they actually have a few devices) : https://www.amazon.co.uk/dp/B081NBCJRS
CONNECTIONS:
GROUND -> DMX Ground Pin 1
OUTPUT A+ -> DMX Pin 3
OUTPUT B- -> DMX pin 2
