1. Product Introduction
This device accepts a single HDMI input and splits it into one HDMI and four HDBaseT
outputs. The splitter is designed with an IR loop out and loop in which are intended to
cascade to additional units. It supports video resolutions up to 4K@60Hz 4:4:4 8bit and
all HDMI audio formats. It can extend 1080p signals on each output to a maximum
distance of 229 feet (70 meters) and 4K signals to a maximum distance of 131 feet (40
meters) over a single CATx Ethernet cable. It supports Power over HDBaseT (PoH)
feature, which allows the receivers to be powered from the splitter over the Ethernet
cables. It supports bidirectional IR pass-through and IR, RS232 cascade control.
1.1 Features
Support HDMI 2.0, video resolutions up to 4K@60Hz 4:4:4.
Distribute one UHD/ 4K HDMI signal to four HDBaseT outputs and one loop HDMI
output.
Supports cascade connection, distribute video signal to multiple video displays.
Maximum transmission distance is up to 40m for 4K, and 70m for 1080p.
Supports video resolution down-scaling, 4K input can be automatically down scaled
to 1080 output.
Supports audio de-embedding.
Each HDBaseT output supports IR pass-through.
Supports RS232 and IR cascade control.
Supports 24V PoH, the HDBaseT receiver can be powered by the HDBaseT splitter.
