The CatCore SMD 3M3F is a four-channel adapter box designed to transmit analog/AES/DMX signals over a shielded Cat5/Cat6/Cat7 cable. It features two Ethercon ports (input and output) for daisy-chaining multiple units or creating cascaded adapter systems. Each channel provides parallel 4x XLR 3M and 4x XLR 3F connections, supporting mixed 3- and 5-pin DMX configurations and bidirectional audio applications. The device enables structured cabling on trusses and stage sub-multicores. Mounting options include M10 thread on bottom, safety wires, cable ties, screw mount, or Velcro. Pinout follows AES72/3E.
