Share to:

LK9 is a DP HDMI VGA 3in1 to HDBaseT converter, wall mount HDMI DP VGA mini switcher over Cat 5/Cat 6 cable in HDBaseT protocol.

Introduction

LK9 is an HDMI/DP/VGA wall plate with HDBaseT output. It sends HDMI, audio, bidirectional RS232 and IR signals up 

to 230ft/70m over a single Cat6/6a cable. It provides a RS232, IR in and out, audio embedded with VGA in front panel, 

users could switch sources with the front button or RS232 command. LED indicators show the status of each input.

There are 2 working modes for LK9, auto mode and manual mode. In auto mode, it will auto detect inputs, and switch 

to the latest connected source automatically.  In manual mode, users have to switch to the connected source 

manually.

There is a micro USB connector in the front panel, which could be used to update the firmware. RS232 port also available 

in back cover side. LK9 could be powered up by local supply or POC powered by remote receiver, 

there is an extra 24V power output if local power is not available .


Features

● HDMI1.4, HDCP1.4 compliant

● HDBaseTTM technology

● Use the privately-owned DDC Emulation technology, improved compatibility.

● Firmware could be updated by Micro-USB

● Support video resolution from 480P to 4K@60 4:2:0, support 3D video.

● Transmit 4K video up to 131ft/40m, 1080P video up to 230ft/70m with Cat6/6a cable

● Uncompressed video, bandwidth 10.2Gbps

● Support bi-directional IR and RS232 control signal

● Support audio embedded and de-embedded

● Support audio separate from video transmit up to 70m

● Bi-direction POC (power over cable) 24V, one power supply to power up both Tx and Rx

● Both side support POC on off switch

● Recommend to use CAT6/6a/7 cable, 70m cable resistance should be less than 10 Ohm
