The Evolution by Vanco EVEXHDB1 HDBaseT Extender over Single Cat5e/6 with RS-232, bi-directional IR, auto EDID/EQ, and PoC extends 4K/UHD and high definition video and audio with RS-232 and IR signals, and power up to 131'/40m over a single Cat5e/6 cable. RS-232 pass-through allows for third-party integration or to send control signals to the connected display. Also features Power over Cable (PoC) Technology, which transmits power over Cat5e/6, allowing either the Transmitter or Receiver to be powered without the use of a power supply, you pick and choose which side to power. No EDID or EQ adjustments are necessary as the units automatically adjust for compatibility and gain. For extending HDMI over a single Cat5e/6 with RS-232, IR, and PoC, the EVEXHDB1 is a great plug-and-play solution for extending 4K UHD signals. The EVEXHDB1 includes two units; transmitting unit (EVEXHDB1-TX) and receiving unit (EVEXHDB1-RX). The transmitting unit is used to capture the HDMI input with RS-232 and IR signals and carries the signals over a single Cat5e/6 cable. The receiving unit is responsible for equalizing the transmitted HDMI signal and reconstructing RS-232 and IR signals.
