I know this is probably a bit off topic, but i learned about this device on this list, and I am desperate. (Installation opens monday). I am running the USB-DMX-Pro on OSX in max-msp. I have installed firmware 1.43 and latest VCP driver from http://www.ftdichip.com/.
It is working fine for controlling my standard dimmerbox via 5-pin to 3-pin convertor (wired 1-1, 2-2, 3-3, but when controlling these LED lights I get random flickering. They use 4 dmx channels. (brightness, R,G,B). Those all are responding as expected except for the flickering.
If I quit max and just allow the usb dmx pro to continue updating the lights the same thing occurs, so I know the problem isn't with max.
Anyone else have experience like this with this unit or DMX-LED light arrays? (I am not sure what the brand is of the lights, they are rentals and it isn't written on the unit) I know the light isn't broke because this happens on all of the units. (12) I've tried all different refresh rates, baudrates, with a terminator, etc.
