Connections and cable planning
Connect the DVI input to the video source and use USB for screen configuration. The control areas of the two Ethernet outputs can be set separately. USB cascading supports multiple sending devices, and the specification also lists multiple-screen control and background playback in extended mode.
The 2016 V1.0 document lists CAT5 runs up to 140 m and CAT6 runs up to 170 m. Confirm the proposed cable, hardware revision and installation before relying on those distances. Optical transmission requires suitable external transceivers; the document provides no specific optical module or finite fiber-link distance for this sending box.
