1. Introduction
The HDBaseT™ HDMI Extender Set enables uncompressed,
high-resolution signal transmission over large distances using a simple
copper data cable. The maximum transmission distance is 150 m (Full
HD). 4K signals can be extended to up to 120 m. Thanks to PoC, only
one unit needs to be supplied with power by an external power
adapter. RS232 and bi-directional IR transmission are also included as
features. Thanks to an HDMI loop-out to the transmitter unit, a local
monitor can be connected to control the output to the receiver.
