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 .

1. Power Indicator: Solid blue, transmitter is powered on; No light, transmitter is not powered
2. VGA IN: Connect to VGA source
3. Audio In: Connect to 3.5mm analog audio, this audio in will embedded to VGA.
4. IR IN: Connect an IR receiver, the IR signal received from this port will be sent out via HDBaseT receiver
5. RS232: Connect a serial RS232 signal here, this RS232 data will pass through to HDBaseT receiver.
6. HDBaseT Link Indicator:
7. VGA Indicator:
8. Select Button: Used to switch among different inputs.
9. Service: Firmware update via micro USB port.
10. IR Out: Connect an IR emitter, the triggered IR signals are received from HDBaseT receiver
11. DP Indicator:
12. DP IN: Connect to DP source here ex. Mac, PC, laptop.
13. HDMI Indicator:
14. HDMI IN: Connects a HDMI source here ex. Blu-ray player, cable box, etc

1. HDBT OUT: Connects a cat6/6a cable from here to an RX-DV70EA receiver, it can receive POC power, it does not provide POC power output.
2. RS232: The RS232 here is used to control the wall plate, like switch,resolution, and picture adjust.
3. Power: Power In and power out here, Middle pin is GND, out 24V in left, In 24V in right.
