This board provides hardware-based control inputs for our Light EFX-16 board. There are two pairs of connectors on this input board; each pair contains a 10-pin connector and a 16-pin connector. The two pairs are split between inputs 1-8 (corresponding to Lights 1-8 on the Light EFX-16) and inputs 9-16 (corresponding to Lights 9-16 on the Light EFX-16). The input board obtains its power from the Light EFX-16 board and communicates with it through the 6-pin header on the left-hand side of the board. When properly connected, and power turned on, a green LED will illuminate on the input board.
