1. Begin with the KD-HD8X8 and all input/output devices turned off with power cables removed.
2. Connect HDMI sources to the appropriate input ports on the KD-HD8X8.
3. Connect display devices to the HDMI outputs.
4. Connect power to the KD-HD8X8 as well as to all other input and output devices
and turn them on.
5. Operate the KD-HD8X8 switcher via front panel buttons, IR Remote, Serial IR
or RS-232 control.
Operation:
After performing the setup above, the unit is ready for operation.
There are several options for controlling the unit. Commands can be issued via IR remote control,
RS-232 or by using the front panel buttons. Note: the advanced commands are available only via
the RS-232 protocol.
Settings
The KD-HD8X8 features a library of 12 internal EDID files, in addition to allowing an Input source
to receive a copy of the EDID information of any selected Output. The default EDID setting is “01”
- 1080i w/ PCM 2ch Digital Audio. Changing to different EDID settings may be necessary when
connecting to or from an AV Receiver, or for passing 3D content derived from a Cable or Satellite
source if the default EDID has problems. They can also speed up the switching process with cable
or satellite sources.
Default Library EDID Control Table:
01 1080i Video, 2ch PCM Audio 07 3D/1080p Video, 2ch PCM
02 1080i Video, DTS/DOLBY Audio 08 3D/1080p Video, DTS/DOLBY Audio
03 1080i Video, DTS/DOLBY/HD Audio 09 3D/1080p Video, DTS/DOLBY/HD Audio

06 1080p Video, DTS/DOLBY/HD Audio 12 DVI 1920x1200 Video, No Audio
When selecting an EDID from the library (settings 01-12), your source device will see the KD-HD8X8
EDID information instead of the display’s EDID. If your display is not capable of accepting the video
resolution or audio type selected, you may not see a picture or or hear sound. In this case please
choose a more compatible EDID, or use the default EDID.
EDID settings can be changed via the Device Manager software or through the RS-232 command
protocol. See the RS-232 command section below for a list of EDID commands available.

EDID Control
EDID Control HDMI Handshaking
EDID (Extended Display Identification Data) is a data structure provided by a digital display to
describe its capabilities to a video source. This data is also known as a “handshake” and typically
includes manufacturer, serial number, product type, resolutions supported by the display, display
size, pixel mapping data, etc.
In a one-to-one source-display system, the EDID process is relatively simple. However, HDMI
matrix systems enabled by the Digital IQ Series products are far more sophisticated as a source
may be selected by multiple displays–with a variety of EDID information provided–at any given time.
Key Digital EDID Control allows the integrator to choose the handshake that will be provided to
each source device of the system. The EDID handshake is relayed to the source from the Digital IQ
matrix, not from any of the displays/output devices of the system. This handshake will always be
the EDID information that the source device receives.
EDID Control handshaking can be provided to each source independently, or to all sources
simultaneously.
The EDID information is provided to a source by one of two methods:
½By copying the EDID provided by any display/output device connected via the HDMI output
connection
½Providing an EDID Handshake from the Default Library
The Default Library features generic EDID handshakes that are compatible with the majority
of source equipment and meet a wide-spectrum of demands in a variety of application
types.
½The Default Library is subject to change as new standards and desired application updates are
requested.
½The EDID Control library can be revised on your Digital IQ matrix via a firmware update. To verify
the Default Library of your unit’s firmware, use the RS-232 Help command (“H”). See the RS-232
Control Codes sections for more information.
Default Library EDID Control Table:
01 1080i Video, 2ch PCM Audio 07 3D/1080p Video, 2ch PCM
02 1080i Video, DTS/DOLBY Audio 08 3D/1080p Video, DTS/DOLBY Audio
03 1080i Video, DTS/DOLBY/HD Audio 09 3D/1080p Video, DTS/DOLBY/HD Audio
04 1080p Video, 2ch PCM 10 DVI 1280x1024 Video, No Audio

06 1080p Video, DTS/DOLBY/HD Audio 12 DVI 1920x1200 Video, No Audio
½After executing EDID Control handshaking for your system, it is recommended to observe video
and audio performance in all zones.
Providing a Default Library EDID handshake to a specified source:
½Via Device Manager (recommended):
»Please see the device manager manual for instructions
½Via RS-232:
»“SPCEDIDxxDyy”
»xx = input Port number or “A” (all)
»yy = default library selection (01-12)
»After giving the source device a few moments to adjust its output, you may verify the
handshake has been properly received and the source has complied with the handshake by
using the RS-232 Input status command “STPIxx”.
½Via the Remote Control:
»See the IR Remote Control section
How to copy the EDID of a connected display/output device
½Digital IQ products are able to poll any connected output device for its EDID information and
provide that EDID to the specified source.
½It is possible to poll any output device connected via the HDMI connections.
½An exact copy of the EDID file provided by the specified output device is relayed to the specified
source.
KD-HD8x8_Manual.indd 10-11 8/29/12 5:26 PM

12 13
½This EDID file is not stored in the Digital IQ unit’s software. Therefore, it is not possible to
relay the copied EDID of an output device unless it is connected at the time of prompting the
handshake.
½Bear in mind that relaying an exact EDID handshake from one of the connected output devices
may result in optimum performance in that respective output zone, but may also result in
incompatibilities in other zones viewing that source with different display equipment.
½After executing EDID Control handshaking for your system, it is recommended to observe video
and audio performance in all system zones.

»xx = input Port number or “A” (all)
»yy = Output Port number (01-08)
»H = output device connected via HDMI (H)

Control Routing via Digital IQ
™
In addition to HDMI matrix switching, Digital IQ products are able to route IR and RS-232
commands to peripheral devices. Control routing via KD-HD8x8 utilizes a proprietary IQ Control
™
technology that consolidates IR or unidirectional RS-232 signals onto the head of Champion
Series
™
HiFi Commercial PRO HDMI Cables. The 3.5mm stereo expansion connections and IQ
Control
™
port are engineered to carry signals in specific directions. As a result, control routing with
the KD-HD8x8 is limited to one direction–from the switch to the “display” end of the IQ Control
™
HDMI cable head.
Utilizing Digital IQ’s Control Routing feature significantly extends the reach of your control system–
adding up to 8 control ports to your control system without requiring additional master control units.
There are two methods of Control Routing: Port to Port and Masking. It is possible to utilize both
control routing methods within your Digital IQ matrix, but keep in mind that settings may interfere
with each other and result in undesired control source–control destination connections.
For seamless integration that fully utilizes the Digital IQ control routing features, Key Digital’s
Compass Control
®
system is recommended. The Compass Control
®
RS-232 and TCP-IP Manager
Databases feature individual drivers for independent IR and RS-232 matrix switching.

Theory: Port to Port Control Routing and Masking
Port to Port Control Routing works much like a traditional matrix switch. A control signal is
transmitted into one 3.5mm expansion port and is routed to a specified HDMI output. The
3.5mm expansion ports are sources (inputs) for a control signal and the HDMI ports are outputs
(destinations) for the control signal. KD-HD8X8 control routing is unidirectional. The control signal
travels from the switch (source) to the display (destination). The control sources (inputs) can be
connected to any 3.5mm expansion control port. A control signal is able to be sent to one or many
control destinations.
Port to Port Control Routing in Brief:
½IR/RS-232 signals from a Control System to expansion ports are routed to a specified HDMI
destination.
½Benefit: Control signals are consolidated onto the Champion Series
™
HiFi Commercial PRO
HDMI Cables with IQ Control
™
technology with video and audio signals, negating the need for
additional cabling to carry control signals.
½Con: Any Port to Port combination is possible, but may require many commands to establish.
Output Masking Control Routing enables a highly-customizable, large-configuration IR or
RS-232 distribution block. A control signal is fed into a 3.5mm expansion port and is distributed
to any number of HDMI destinations by issuing, in conjunction, the proper routing and masking
commands. If commands are issued incorrectly or control connections are changed, the control
signal may be disrupted.
KD-HD8x8_Manual.indd 12-13 8/29/12 5:26 PM

Output Control Masking enables a control signal fed into a 3.5mm expansion port to be routed to
any combination of HDMI ports.
Control Masking Routing in Brief:
½Signals from a Control System are routed from specified 3.5 mm ports to any combination of
HDMI ports
½Benefit: Any specified combinations of destinations are granted connection to the source
control ports via a minimal amount of commands.
½Con: Programming can be complex, as commands featuring Hex values may need to be issued
frequently depending on how dynamic the system is.
Implementing the Control Routing Features:
How to Set Port to Port Control Routing (IR & RS-232)
1. Determine source and destination for control signal(s):
»For Control Routing Systems: “SPCIRxxyy”
»xx = Destination (01-08 = HDMI 01-08)
»yy = Source (01-08 = 3.5mm 01-08)
2. Send IR/RS-232 command to be routed
3. (Optional) Disconnect all source-destination relationships:
»a. For IR Control Routing Systems: “SPCIRA97”
»A = All destinations
»97 = Disconnect from source

How to Set Masking Control Routing:
1. Route a 3.5mm expansion port to HDMI output/destination ports:
»a. To route a 3.5mm expansion port to all HDMI output/destination ports:
»IR/RS-232: SPCIRAyy
»Note: this command may interrupt existing Port to Port routes in place
»b. To avoid interruption of existing Port to Port routes, route individually:
»IR/RS-232: SPCIRxxyy
»xx = Destination (01-08 = HDMI01-08)
»yy = Control signal source (01-08=3.5mm expansion port 01-08)
2. Establish Output Mask:

Digital IQ Control Routing with Compass Control
®
System
Key Digital’s Compass Control
®
System features drivers to maximize the capability and ease of use
for control routing with Digital IQ products. Each control routing matrix (IR and RS-232) features
an independent driver in the Key Digital RS-232 Manager database, essentially treating each
independent routing matrix as its own independent device. The drivers are named KD-HD8X8_IR
and KD-HD8X8_RS.
Integrating Digital IQ with Compass Control utilizes a method of Control Routing that is a hybrid of
the Port to Port and masking methods because it takes advantage of the KD-MC2500’s (Compass
Control Master Controller) flexible port configuring, which does not limit each port’s protocol to the
protocol of the assigned device. Instead, the protocol of each KD-MC2500 port is determined by
the device that the control signal is intended for, allowing multiple devices to be assigned to any
port. For example, a single port can issue an RS-232 command at 9600 bits per second, and then
issue the next command at 57,600. It is important to ensure that proper delays have been added to
the sequence.
The flexibility of the KD-MC2500 ports enables a minimal amount of connections from the master
controller to the Digital IQ. Providing three ports from the master controller to the Digital IQ is
recommended, and will provide connections to control the Digital IQ’s independent matrix layers
(Video, Audio, IR, RS-232), external IR devices (via control routing), and external RS-232 devices (via
control routing).
Recommended connectivity between Digital IQ and KD-MC2500:
1) DB-9 to DB-9 Straight cable, providing control over the Digital IQ
2) 3.5mm Mono which will be the IR source for control routing to external IR devices
3) 3.5mm Mono which will carry the RS-232 transmit signal for control routing to
external RS-232 devices

Adding the KD-HD8X8_IR and KD-HD8X8_RS to your Compass Navigator System Configuration
Device Library will add two device icons:
»Adding KD-HD8X8_IR inserts “KD-HD8X8_IR <RS>” and “KD-HD8X8_IR <in1>”.
»“KD-HD8X8_IR <RS>” carries the RS-232 command determining IR destination
and IR source matrix switching and is depicted with connection number 1 in the
above diagram. In the Compass Navigator Controlling Flow Connectivity Tree, the
“KD-HD8X8_IR <RS>” device should be connected to the Main RS-232 port
of the KD-MC2500.
»“KD-HD8X8_IR <in1>” is the connection that carries the IR signals intended to
be routed to IR destinations. In the Compass Navigator Control Connectivity Tree, the
“KD-HD8X8_IR <in1>” device can be connected to the or any of the eight 3.5mm
multifunction ports of the KD-MC2500 (as long as the ports are pre-configured to IR)
and doing so will create a tree expansion for 8 IR destinations
Brand: Key Digital → Device Type: IR Router → KD-HD8X8_IR
Adding “KD-HD8X8_IR <in1>” to the Main IR Port
(“IRout-60”) provides 8 additional IR connectivity points. Ports
5 and 6 (HDMI ports on Outputs 5 and 6, respectively) are
routing control to the “Lab” and “Lobby” displays.

Audio Return Channel
Audio Return Channel features rely on CEC to work effectively. CEC is not enabled through the
KD-HD8x8XC matrix; therefore a CEC connection must be made elsewhere. This connection can
be enabled by connecting two HiFi Pro 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.
