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 R.I45 output however for best performance use cat6a or cat? (particularly in electrically noisy environments). The maximum distances & transmission performance for HDA41 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 a solid copper core of 23AWG (avoid CCA type). in one straight run (avoid/minimize patches) and avoid close proximity to any noisy electrical sources.
