Greetings,,,
The LE can use the optional EX/RX (Express Receiver) that plugs directly into the LE board, where the wireless module spot is left after the LE is built.
Or you can use the standalone DMX Receiver that turns the wireless signal into a wired DMX signal that plugs in to the DMX input, just as the normal wired signal would.
In either case, you need a DMX transmitter, plugged into the dongle, or elsewhere along the wired DMX line.
