You can enter a DMX universe number and a device address to have DMXCalc calculate the absolute address. Or enter an absolute address to see the universe and device address.The + and - buttons can be set to increment or decrement the address by any step size. Handy for addressing a sequence of moving lights. When there is not enough space in the current universe for another fixture, the Address and + values turn red.
Some DMX equipment utilizes dip switches to configure the address. The row of dots at the bottom of the DMXCalc display guides the setting of dip switches. Characteristics of the dip switch display can be set by tapping the ... button.
