Installation and Operation
Before permanently securing the unit for final installation, test for proper operation of the unit and
cables in your system. It is recommended that you leave enough ventilation space to provide
sufficient airflow and cooling.
Push Button Control
The KD-4x4CSA/KD-8x8CSA unit may be controlled via the push
buttons on the front of the unit. Choose which output to change
and then select the desired input by pressing the corresponding
“Input Select” button. The front LED indicators (1, 2, 3, 4/5, 6, 7, 8)
correspond to the input that has been selected for each output.
IR Remote Control
The KD-4x4CSA/KD-8x8CSA may also be operated using the
IR Remote provided with the unit (The remote is powered by a
CR2025 Battery). The KD-4x4CSA/KD-8x8CSA switcher features
an IR sensor on the front of the unit for reception of signals.
IR Emitter Control
The IR Sensor on the front panel may also accept signals from a
Compass Control Master Controller or from a 3rd party control
system. When using a Master Controller or 3rd party control
system, the IR Emitter must be mounted over the IR Sensor on
the front of the KD-4x4CSA/KD-8x8CSA unit. The other end of
the cable is connected to the Multi-function I/O port on the Master
Controller or the IR Extender/IR Connecting Block of the 3rd party
control system.

Serial IR, RS-232, and TCP/IP Control
The KD-4x4CSA/KD-8x8CSA features a 6-Pin Terminal Block for IR and RS-232 Control. Signals
may be received from these connections as well as the Ethernet Jack for TCP/IP Control. Serial
commands may be found in the “Communications Protocol” section.
For Serial IR, connect a mono cable to the Multi-function I/O port on the Master Controller or
the IR Extender/IR Connecting Block of the 3rd party control system. The other end would then
connect to Pins 1 and 2 on the 6-Pin Terminal Block. IR In is Pin 1; Ground is Pin 2.
For Serial RS-232, connect a stereo cable to the Multi-function I/O port on the Compass Control
Master Controller or the RS-232 port of the 3rd party control system. The other end would then
connect to Pins 3,4,5,6 on the 6-Pin Terminal Block. Tx Data is Pin 3; Rx Data is Pin 5; Ground is
Pin 4 and/or Pin 6. Either ground pin may be used for RS-232.
For TCP/IP control, connect an Ethernet cable from the KD-4x4CSA/KD-8x8CSA to a network
router or connect a crossover cable from the KD-4x4CSA/KD-8x8CSA directly to a PC.

›The Pin assignment for the audio is as follows:
»Left + is Pin 1; Left - is Pin 3; Left Ground is Pin 2.
»Right + is Pin 4; Right - is Pin 6; Right Ground is Pin 5.
›Each Output Channel has 1 Digital Audio Output: RCA Jack which provides de-embedded
Digital Audio Output from selected HDMI input
›There are no volume or tone control features, only muting control of the external audio outputs
via RS232 and TCP/IP
›There are no DSP features. Audio must be configured in the source. For example, in order to
achieve 2ch analog audio output, the selected HDMI input source audio format must be 2ch.

Settings and Adjustments
The KD-4x4CSA/KD-8x8CSA unit may be configured using the provided IR Remote. Such settings
and adjustments include unit address, matrix switching, and EDID settings. Factory Reset may be
completed by using the push buttons.
Addressing Mode
Units may be addressed when used in a multi-unit system. The Key Digital IR Remote is required
to change the address of the KD-4x4CSA/KD-8x8CSA unit. Please press the following sequence
on the Key Digital IR Remote to change the address.
R3 » R1 » R2 » X » X
»X= Numeric Keypad Button from the IR Remote (Device Select)
»Default address is 00 – Single unit mode.
»All addresses must be two digits long
»All LED lights will blink once to confirm the address has been set.
»Once a unit has been addressed, the two digit address must precede all IR command
sequences
Matrix Switching
The Key Digital IR Remote is required to change the selected input to an output of the KD-
4x4CSA/KD-8x8CSA unit. Please press the following sequence on the Key Digital IR Remote to
switch the input of an output.
B » A
»B= Numeric Output Button 1 through 8 from the IR Remote (Output)
»A= Numeric Input Button 1 through 8 from the IR Remote (Input)
EDID Control
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.
Key Digital EDID Control allows the integrator to choose the handshake that will be provided to
source devices of the system. The EDID handshake is relayed to the source from the Champion
Series switch, or from the first connected display (default setting). This handshake will always be
the EDID information that the source device receives.
The Key Digital IR Remote is required to change the EDID of a specific input. Please press the
following sequence on the Key Digital IR Remote to change the source EDID settings:
R2 » R1 » R3 » A » X » X
»X= Numeric Keypad Button from the IR Remote (Device Select)
»A= Numeric Input Button 1 through 8 from the IR Remote (Input)
»All LED lights will blink once to confirm the EDID mode has been set.
The EDID may also be copied from a specified Output to a specific Input. Please press the
following sequence on the Key Digital IR Remote to change the EDID settings:
R2 » R1 » R3 » A » B
»A = Numeric Input Button 1 through 8 from the IR Remote (Input)
»B = Numeric Output Button 1 through 8 from the IR Remote (Output)
»All LED lights will blink once to confirm the EDID mode has been set.
The possible EDID settings can range from ‘00’ to ‘15’. (‘04’ is the default).
