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”.

Settings

The KD-HD4x4/6×6/8x8Lite features a library of 12 internal EDID (Extended Display Identification Data) files, in addition to allowing any Input source to receive a copy of the EDID information of any display connected via HDMI or CAT cable. The default EDID setting is “04” – 1080p 2ch Digital Audio. Changing EDID settings may be necessary when connecting to or from an AV Receiver, or for passing 3D content.
The possible EDID settings can range from ‘01’ to ‘12’. (‘04’ is the default).
01| 1080i, 2CH Audio| 07| 3D, 1080p 2CH Audio
---|---|---|---
02| 1080i, DOLBY/DTS 5.1| 08| 3D, DOLBY/DTS 5.1
03| 1080i, HD Audio| 09| 3D, HD Audio
04| 1080p, 2CH Audio| 10| 1280×1024 DVI
05| 1080p, DOLBY/DTS 5.1| 11| 1920×1080 DVI
06| 1080p, HD Audio| 12| 1920×1200 DVI
When selecting an EDID from the library (settings 01-12), your source device will see the KD-HD4x4/6×6/8x8Lite EDID choice instead of the display’s EDID, overriding the display’s own EDID information.
If your display is not capable of accepting the video resolution or audio type selected, you may not see a picture or hear sound. In this case please choose another more compatible EDID, or use the default EDID.

Remote Control

You may switch inputs on the KD-HD4x4/6×6/8x8Lite by using the supplied IR Remote control. You can also perform basic EDID adjustments with the IR remote.
Please see the below chart for IR remote commands
