can the lights be run by DMX? most likely possible, but somone would have to design the hardware to interact to this particular node. remember these were made custom to conform to a specific application. so they may not act like similar nodes even with the same chips involved. ther's a reason for the chip used, there's a reason for the voltage used, there's a reason for the number of conductors used in the interlink cable. I don't know the reasons but i do know if the normal nodes that look like these could have been used, then there wouldnt have been a reason to make these.
plus... with 128 node strings... after the first string, then you could only fit a 42 node string before you run out of DMX channels... so what's the point?
