The 444K-TX660 is a self contained HDBaseT splitter capable of transmitting HDMI signals up to 4K UHD resolutions over 70m of Cat 6 cable.

A single HDMI input can be connected to the rear of the unit where it gets split internally and then fed to 4 separate HDBaseT outputs. Each receiver (444K-RX875) decodes the HDBaseT protocol back to HDMI and RS232. Power is provided from the transmitter through the same Cat cable so there is no need for bulky PSUs at the display end. A secure lockable DC connector on the splitter provides a reliable power connection.

Each HDBaseT connection also allows for RS232 signals to be received back from the receiver enabling remote control of the source device. Fully HDCP 2.2 compliant this 444K-TX660 compact unit is ideal for digital signage use in Education, Entertainment and Retail Market.
