RandoziDMX Address Calculator
List your fixtures and their channel modes. The patch is computed fixture by fixture, starting a new universe when the next one would not fit.

How it works
- Write one line per fixture type: name, channels per fixture, and how many you have (for example Par LED, 8, 12).
- Set the first universe and the first address, and an optional gap of free channels between fixtures.
- Read the table of start addresses and universes, and the number of universes you need.
- Copy the patch list into your show file or print it for the rig.
What people use it for
Small shows
Patch a dozen LED pars and a few movers without a console.
Checking a rig
See how many universes a fixture list needs before you buy a node.
Spare room
Leave a gap between fixtures so you can switch to a longer channel mode later.
Questions
- How many channels are in a universe?
- 512. A DMX512 universe carries channels numbered 1 to 512, as defined by the ANSI E1.11 standard. A fixture uses consecutive channels starting at its start address.
- Why does the next fixture jump to a new universe early?
- A fixture cannot be split between two universes. When a fixture of 16 channels would end past channel 512, it starts at address 1 of the next universe, and the unused channels at the end are counted as wasted.
- Does it know my fixture’s channel modes?
- No. You enter the number of channels of the mode you actually selected on the fixture. Check it in the fixture manual: the same model often has 3, 8 and 16 channel modes.
