1. Product Introduction
The KanexPro EXT-HDBTKVM3 is a US Decora style double-gang, 2x1 HDMI
wall plate transmitter and receiver set designed to switch two HDMI inputs with
one USB 2.0 input to a remote display or a projector up to 131ft.(40m) at
4K/60 and 330ft.(100m) at 1080p/60 video and audio over single cat5e/6/7
cable. The outputs are via HDBaseT port.
Easy to Control and Switch Inputs
The wall plate transmitter can be easily controlled by selecting the “Source
/Auto” button on the front panel. By holding the button for 3 seconds, it will go
under auto switching mode and will auto-detect HDMI inputs when connected.
It also supports CEC, which can turn the DISPLAY ON/OFF right from the
button on front panel for the far-end display device, and it can be programmed
by IR learning or RS232 command to ensure the compatibility with various
display devices.
Receiver Inclusive with two USB 2.0 ports and KVM support
The EXT-HDBTKVM3 includes the end point for connecting it over ethernet to
the receiver, which then connects to the 4K display. The receiver has multiport USB 2.0 which can be used as a KVM or for VTC applications.
PoH – A Safe and Regulated Power for Sustainability
The output from the wall plate is via HDBaseT port. The receiver powers the
wall plate remotely. Power over HDBaseT (PoH) offers voltage protection
when sent over ethernet without burning the other side of devices or receivers.
Our wall plate kit comes with only one power supply, which means that, it can
be powered from the receiver side saving installers time and added cost to
installing a power outlet.
