I have an old Colortran ENR 96 Dimmer rack that flashes when it receives DMX from the lighting board. Viewpoint works fine but any intensity over and above the View point setting causes the lights to flash. This is an intermittent problem (of course).
I have swapped out lighting boards, Viewpoint module as well as both controller modules…twice. Just today the flashing started when the lighting board was plugged in and not sending ANY intensity out (faders at zero, grand master at zero, black out button of doom engaged). Unplugging DMX stops the flashing. The cable is true DMX, shielded and has been working for 9 years so I don’t think that’s the problem
Not sure where to go from here. It’s almost like the DMX interpreter chip is getting through when it’s not supposed (like two boards “Y” cabled together) to but with 6 controller modules and 2 viewpoint modules replaced I don’t know what to say. The ONLY thing in common is the EPROM that has to remain with the racks since the rack in question is phased balanced and the donor racks are sequential, but I can’t see how that would be an issue. The donor racks were is good working order when we replaced them 5 years ago, but since the problem remains the same I doubt each rack suddenly broke the same way.
And Ideas?
