I have 4 expresses and 4 SSRs in my show this year. I had them all wired up to use DMX until I could get my RGB strings ready to go. Everything was working fine using the lynx usb dongle with the dmx chip installed. I added the RGB strands and hooked up the pixelnet hub. Now I can get the rgb strands to light up, but none of the dmx strands will light. I have checked all of the expresses and they are all showing a dmx signal. I have checked all of the wires, and have gtried just plugging on express in to eliminate any other possible issues down the line. I have double checked the jumpers on the hub to make sure that they were set for the first DMX universe, which to my understanding means that channels 1-512 of the pixelnet data will be sent to the dmx out port on the hub. My DMX channels are set for channels 1-88. i can turn on all of the RGB string channels, but none of the dmx channels will work at all. Has anyone seen this? I am using vixen 2.1 with the pixelnet plugin. I have programmed all of the smart strings to be on the correct starting channels. Does anyone know about some other settings in Vixen that I might need to make? Any other things I could check? I have checked and double checked everything I can think of. I have even unhooked everything except one express, and still no dmx even though the dmx data light is on when I plug in the cat 5 cable to the express from teh dmx port on the hub. I have tried different cat 5 cables as well. I am really stumped and disappointed because my lights won't turn on.
