Ok.... I was plugging in my ML for my theater, and the Green light on the DMX wall connector turened off. I went to check the main input and the main power light was off. So I went to my Sensor racks, (we have 154 Dimmers for a 300 seat theatre + 40 for our black box) But I cant restart the second universe. It controls the ML array. OH... I went to the rack status page on my ETC Express 48/92 desk, and it said there was a ETC Link ERROR on rack 2 port B. Also, the next day when I turn the light board on, it said that there was and advisory for DMX 512 port B!!!! HELP HELP we have a dance show coming up and I need to use the DMX system, what can I do!!
