DMX Calculator

Addresses, universes, overlaps. Free, no account — nothing is stored: everything is computed in your browser.

Your fixtures

The start address is for when the first channels are already taken by gear that is not in this list — a dimmer rack, a machine wired in permanently. A fixture whose universe is chosen stays there, whatever happens.

Proposed patch

The patch chains each fixture right after the previous one. To anchor a fixture to a precise address without moving what is already placed before it, change its address in the table : the rest picks the chaining back up right after it.

The gaps between addresses

What you type into a console : N fixtures, first address A, step P. If the gap is constant, the entry fits on one line. If it is not, you have to address fixture by fixture — and it is better to know before you are up the ladder.

The map of all 512 channels

One square per channel, thirty-two to a row. A whole universe reads at a glance : the occupied blocks, the gaps between them, and the overlaps.

The patch sheet

What the button prints, as is. The name, logo and contact details come from the settings above (« Personalize the sheet ») — left empty, only Adresso's own header appears.
