The Node 4 is an Ethernet to DMX bridging device. It accepts either Artistic License's ArtNet (version 3) or PLASA's streaming ACN (ANSI E1.31) protocol. There are four fully isolated DMX ports. Each port can be configured as either an input or as an output. All of the data connectors can be mounted on either the front or rear panel. Their location can be changed in the field to accommodate fixed or touring installations. Optional terminal block connections are available for the DMX ports.
