Addressing your DMX fixtures involves designating the location within the 512-channel universe where a specific DMX device resides. This location is commonly referred to as the "start address," as it marks the first address utilized by a particular fixture.
For straightforward devices with just one channel, like a basic single-colored light that can be toggled on and off, the addressing process is relatively straightforward. These fixtures can be consecutively addressed, assigning address 1 to the first, address 2 to the second, and so on. This simplicity makes the process intuitive and easy to grasp.
However, the procedure becomes more intricate when dealing with multi-channel fixtures, such as LEDs or moving lights. With these devices, it's imperative to ensure that an adequate number of channels are left vacant before proceeding to patch the next fixture.
Consider a scenario where you have a 3-channel fixture commencing at channel 28. To avoid conflicts and unexpected behavior, the next available address after this fixture would be address 31. Neglecting this crucial step might result in unintended consequences. You might find yourself attempting to control one light while another light responds in an unforeseen manner.
