INTRODUCTION
This 4K 2x4 HDMI® Splitter and Extender Kit allows you to distribute either one of
two HDMI inputs to a single HDMI loop output and four RJ45 outputs for
extension over single Cat5e/Cat6/Cat7 Ethernet cable. The loop output can be
used for a local display or to cascade to additional Splitter and Extender Kits. It
supports video resolutions up to 4K@60Hz with YCbCr 4:4:4, 8-bit, and all HDMI
audio formats. It can extend a 4K signal to distances up to 229 feet (70 meters
and a 1080 signal up to 262 feet (80 meters). It supports the Power over Cable
(PoC) feature, which allows the receivers to be powered by the transmitter over
the connecting Ethernet cables. It supports automatic video downscaling,
bidirectional IR passthrough, IR cascading, and RS-232 control.
