problem with enttec open dmxusb

March 28, 2006 | 1:56 pm

Hi… I’ve just bought the Enttec Open DMX USB device and have been trying to use it to interface MAX/MSP running on Windows XP with a Sound Lab DMX Dimmer Pack using the dmxusb external. I have installed the VCP driver from FTDIchips and the dimmer pack shows that it is recieving a signal by flashing an LED when the ‘open COM4′ message is sent to the dmxusb object. I can’t get it to turn on any channels though. I am sending the message ’0 255′ to the dmxusb assuming this should turn on all channels, but it’s having no effect. Any suggestions.
Cheers, Gordon.
