On Sensor IQ is the output number the same as circuit number or relay?

In Sensor IQ the output number is the same as the slot number, or if the rack is fully populated with 1-pole relays, it equates to a relay. In normal orientation (with the UI at the bottom) the odd numbers are on the left side and even numbers are on the right side, with output 1 at the top-left, and output 48 at the bottom-right.

If the rack is inverted (with the UI at the top) the even numbers are on the left, and odd numbers are on the right, with output 1 at the bottom-right, and output 48 at the top-left.

DMX/sACN numbering always starts with output 1 and goes through output 48 regardless of rack orientation, unless you manually change the addressing of individual outputs. The same holds true for circuit numbering.
