The ARRI SkyLink Receiver (Blue/Silver) pairs with an ARRI SkyLink Base Station (not included) to add wireless DMX capabilities to ARRI lighting fixtures without integrated LumenRadio CRMX receivers from up to 1,640 feet. The receiver has a USB cable to draw power from lights with USB Type-A power ports, but some lights such as the ARRI L5-C will require a separate power source. The receiver simply plugs into and is supported by the 5-pin DMX port of a compatible light.
