1. All transmission distances are measured using Belden 1583A CAT5e 125MHz Solid UTP cable. The transmission distance
is defined as the distance between the video source and the display.
2. To reduce the interference among the unshielded twisted pairs of wires in UTP cable, you can use shielded STP cables to
improve EMI problems, which is worsen in long transmission.
Warning: Do not plug RJ-45 HDBaseT output to non-HDBaseT complaint
devices or damage may occur to either product.
