The HP EPP is an interface between Gotham Incito downlights and a DMX controller. Although the device is in the same enclosure as the nLight nEPP5, it is not capable of communicating directly with an nLight system.
Manual programming of the HP EPP is similar to nLight device, except when one selects the value of the programming function, you do not enter the new setting value - instead, hitting the programming button will add onto the current setting. Going past the highest value setting will reset the value to the lowest (end around).
