Net3 4-Port Gateway with 4 Blank Plates


The Electronic Theatre Controls (ETC) Net3 Four-Port Gateway provides network data distribution of RDM and data level information. Built on the reliability and quality of ETC’s Network development, Net3 gateways are built for the industry standard ACN protocol. The Gateway is an Ethernet device that uses bidirectional communication with other network devices to send and receive DMX512 and RDM data as well as ACN/sACN. This particular model includes 4 blank plate fillers used for rack-mount protection and aesthetics.
