Extending and Routing Control Signals

• The KD-HD4x4/6×6/8x8Lite feature powerful and useful control routing features. The switchers have the ability to matrix control signals just like they can audio and video signals.
• KD-HD4x4/6×6/8x8Lite can consolidate incoming IR/RS-232 signals to control any display/output connected via CAT5/6 or via HDMI (control signal extension via HDMI only available with Key Digital Commercial HiFi ProS cables).
• KD-HD4x4/6×6/8x8Lite can consolidate incoming IR/RS-232 signals to control any source/input connected via HDMI, with Key Digital’s Commercial HiFi ProS cables.
• IR and RS-232 control signals are bi-directional, and may flow from the matrix to the zone or from the zone to the matrix.
• The default signal path for control signals is to route IR control signals from Expansion I/O Port 1 to RJ45 output 1…Expansion I/O Port 8 to RJ45 Output 8 (the path and control signal type can be manipulated by using the desired RS-232 command).
• When connecting the IR Emitter to the device you wish to control, make sure to find the IRreceiver area on the device

Control Signal Extension from External I/O Ports:

The default setting for control signal extension is to route IR signals from Expansion I/O Port 1 to RJ45 output 1…Expansion I/O Port 8 to RJ45 Output 8 (the path and control signal type can be manipulated by using the desired RS-232 command). When routing control signals to/from an HDMI input/output, Key Digital’s HiFiProS cable must be used.

• Point-to-Point control routing is established by using commands containing “IRR” or “RSS”.
• Point-to-Many control routing is established by using commands containing “IR” or “RS”.

Firmware Upgrade Procedure

KD-HD4x4/6×6/8x8Lite units are firmware upgradeable via USB.
First you must download the Device Manager software from the KD-4x4Lite/KD-6x6Lite or KD-8x8Lite product pages on the Key Digital website. The software can be found under the “Downloads” section.

1. Connect the Digital IQ unit to your PC via USB or RS-232
2. Open the Device Manager software and select Download on the Home Page
3. Wait for confirmation that the PC has established a connection with the Digital IQ unit
4. Select Auto Update selection box, and then begin the firmware update by selecting Next
5. Observe status of the firmware update through completion
6. Select Finish to close

Audio Return Channel

Audio Return Channel features rely on CEC to work effectively. CEC is not enabled through the KD-HD4x4/6×6/8x8Lite matrix; therefore a CEC connection must be made elsewhere. This connection can be enabled by connecting two Champion Series™ HiFi Commercial ProS HDMI cables together with a male to male 3.5mm stereo cable from an ARC supported TV and an ARC supported AV Receiver. The audio return channel is not output via HDMI, but instead it is sent to the corresponding 3.5mm expansion port of the output to which the ARC audio is connected to.
A common 3.5mm stereo to L/R RCA Y-cable may be used to connect to your AVR, however, the audio output signal will be PCM digital and will only be carried on one of the RCA leads.
Example: An ARC compatible display is connected to output 8. The audio will be sent to 3.5mm expansion port number 8.

ARC Requirements:

• Display that supports ARC
• AV Receiver that supports ARC
• Champion Series™ HiFi Commercial ProS HDMI Cables
• Male to Male Stereo Cable
