The DMX input function is configured on a per channel basis can be used to trigger a resulting action based on incoming an DMX signal. This is different from the eDMX pass through which allows another source (SACN or KiNET) to be passed though to a controllers DMX ports.
When using the DMX input function it is important to remember that we are limited by the refresh rate of DMX. With this in mind, it is suggested that no more 60 channels of DMX input be used in a single Mosaic project. If we exceed this limit we likely see packet loss and control issues.
