DMX Address Calculator
Convert a global DMX channel number to its universe and address-within-universe (1–512), and see the start address for patching.
DMX512 carries 512 channels per universe, so channel 600 lives at address 88 of universe 2. Lighting consoles and nodes number universes from 1; this maps any absolute channel to the universe/address pair you actually patch — and back, when a node reports a fault by global channel.
