DC Input

Feed DC (12-36V) into the 2 pin green terminal block. The polarity is marked on the PCB.

DMX Input

There are two RJ45 connectors for DMX input / through. They are wired in parallel so it makes no difference which one is used as input. The RJ45 pinout is per the ESTA standard with the addition of pins 4+5 being connected together to allow use in P-DMX systems.


There is a small green LED on the PCB. It indicates the presence of the 5V regulated supply.
