Dimmer issue

Hi!

I`ve been using a Hoglet with Hog 4 pc, but when I plug the dimmer dmx cable, some circuits flash or remain on, even I don`t patch any desk channels, no matter in which dmx out is plugged. The dimmer rack i`m using is an old colortrand.

What can I do?? Please help!!

Also I have already tried plugging a splitter betwen the console and the dimmer rack. Still did not work.

Thank you!!
