I just bought an FC-400 DMX foot controller that I'm trying to program. When in programming mode, I can set channel 1 just fine. Most of the time, setting channel 2 also works OK. Things start to get all screwed up by channel 3 though. Changing the settings on channel 3 or 4 of any given scene alters the previous channels in that scene that I've already set up.
For example, if I set scene 1 channel 1 to show a red light and set channel 2 in that scene to blue, that usually works. If I start scrolling through colors on channel 3, the red & blue on channel 1 & 2 also change.
I'm doing this with 4 single-channel DMX color changers (no dimming), each set to different channels - 1, 2, 3 & 4. I'm assuming that since this controller is only a 4 channel DMX controller that the only channels available are DMX channels 1, 2, 3 & 4. Is that right? And if I'm reading the manual right, I should be able to set up 12 scenes of my own using the FC400. I have no plans to use chases, just static scenes with no moving heads or anything like that. Just using color changers, used like pars that can change colors. We're a blues rock trio and don't need a lot of blinkyflashy, but want more than a couple washes set to auto-stupid. ;D
All cables used are DMX specific without a ground connection to the barrel of the XLR plugs to prevent ground loops in accordance with the DMX standard. I'm also using a terminator, even though I'm only using 4 fixtures and total cable length is only about 50 feet. I've also tried switching the DMX polarity both ways and that's not the problem.
Is there something wrong with my FC400 controller? Obviously I'm not doing anything stupid like powering my DMX color changers on dimmers or anything like that. Everything has plenty of AC power, but as it is I can't get any programs set up to actually use it.
Any help is appreciated.
Cheers,
