CAT Cable Wiring
We suggest both RJ-45 connectors be wired identically following T568B wiring standard for the best performance and compatibility.
Both connectors must be wired identically, to T568B standard.
Note: You may use cat5e, cat6 UTP (cat6 preferred) in conjunction with the 8745 output; however for best performance use cat6a or cat7 (particularly in electrically noisy environments).
The maximum distances & transmission performance for HDMI and USB may be compromised by cable quality, patch panels, poor termination, wall plates, cable kinks and electrical interferences. Generally ensure the cat cable is solid copper core of 23AWG (avoid CCA type), in one straight run (avoid/minimise patches) and avoid close proximity to any noisy electrical sources.

EDID Management
If the HDMI loop-out of the Transmitter is connected to a display device, the HDMI source device will learn the EDID of the local display device, otherwise, the source device will use the built-in EDID (4K @30Hz YUV 4:4:4)
