Fade-to-Black and Video Mute pro-features
“Fade-to-Black” and “Video Mute” features allow you switch like a pro in a live studio.
The Fade-to-Black feature allows for switching between input/output combinations without the
usual visual signal noise that traditionally accompanies switching between Video signals. The Video
image momentarily goes to black as the KD-MSCAT8X8 Matrix Switcher selects between inputs for
the chosen output.
Video Mute enables you to mute the Video signal (the display goes to black) at the chosen output.
Massively Expandable
Massively expandable, the outputs of the 8x8 can be incremented in steps of 8, providing matrix

Getting Started
The KD-MSCAT8X8 Matrix Switcher is capable of switching eight (8) sets of three-wire component
(YPbPr) Video or five-wire component (RGBHV) Video plus Analog and Digital (PCM) Audio. Since
Composite Video input would require just one BNC connector (Red, Green or Blue), up to 3
Composite inputs can be connected to each input field bringing total number of Composite inputs
on a single KD-MSCAT8X8 to 24 ! (Switching in that case would be in sets of 3) Matrix Switcher
is also capable of switching S-Video (with the appropriate cable adapter) from VCR’s, digital Video
recorders and satellite set-top receivers.
Sixteen Audio sources can be switched together or independently from Video sources.
If your source device has a VGA output connector, you will need a VGA-to-BNC breakout cable.
Note: At the time of this manual writing the KD-MSCAT8X8 Matrix Switcher does NOT perform Video processing, the
output Video format is the same as the input Video format. This means that the Video resolution is not changed
and also that if you input one form of Video, for example Component Video, the output will be in exactly the same
format. Flexible hardware and software architecture allows us, at Key Digital, update and improve our products
in accordance with market and client requirements. Always check our Web site for new product capabilities and
latest firmware updates.

Power
The KD-MSCAT8X8 Matrix Switcher Video and PCM Audio Inputs are equipped with professional-
grade BNC connectors. These connectors offer a better match to Video cables than do the smaller
RCA connectors, as well as providing a positive bayonet lock when installed. Because not all
consumer equipment marketed uses BNC connector interfaces, it may be necessary to employ
RCA-to-BNC or VGA-to-BNC adapter plugs and/or cable assemblies to interface these various
devices to your high-quality Matrix Switcher.
Input Analog Audio connections are 6-pin, Phoenix type connecting blocks. Top row marked
with odd numbers, lower – with even numbers.
Output connectors are female RJ-45 for the use with CAT5/6/7, and set of KD-VACRX or KD-
VACWPRX baluns required for proper connection to output A/V devices.
The Video signal format must be considered when making connections to the KD-MSCAT8X8
Matrix Switcher. Simply match source A/V device’s output (be it YPbPr “Component” or RGBHV
“VGA” Video) to a similar Video signal input configuration on the KD-MSCAT8X8 Matrix Switcher.
In the event that these superior quality output formats are not available on the device in question,

then S-Video and/or Composite Video may also be interfaced with the KD-MSCAT8X8 Matrix
Switcher with the use of the appropriate adapters.
The same consideration applies to the Audio interfaces. Both Analog and Digital options are
provided on the KD-MSCAT8X8 Matrix Switcher and may be employed appropriately as Analog,
when connecting to 6-pin, Phoenix type connecting blocks and via KD-VACRX or KD-VACWPRX
baluns to the Analog Audio inputs of a Video monitor; or as Digital, when connected instead to
PCM input and via KD-VACRX or KD-VACWPRX baluns to A/V receiver having coaxial digital (PCM)
interfaces for decoding surround sound signals.

BASIC OPERATION
A “Matrix Switcher” allows you connect an output device (typically a display or A/V receiver) to input
source of your selection.
In 8x8 configuration, for instance, all 8 output devices can be connected to one input or any of 8
output devices can be connected to any of 8 inputs or any combination (group) of output devices
can be connected to any input.
All input/output combinations are configurable via the front panel pushbuttons and the selection is
clearly displayed by LCD display and LED indicators for each of the output fields. Switching can be
accomplished conveniently in any of four ways:
Manually, using the front panel pushbuttons, LCD screen and LED indicators
Remotely, using the supplied IR remote control
Using the RS-232 control
Using TCP/IP protocol over LAN.
Configuration and Setup
Manual routing of Video and Audio signals from the available inputs to selected outputs is easily
implemented on the KD-MSCAT8X8 Matrix Switcher using the front panel pushbuttons, and visually
verifiable via the LCD display and LED indicators for each combination of input/output fields.
The front panel of the KD-MSCAT8X8 Matrix Switcher provides the user with a visual representation
of cross-reference of eight Input and eight Output fields. Each of these cross-points has LED
indicator that will be lit-up when appropriate Input/Output combination chosen.
All switcher functions fully controllable via “Menu”, Directional Arrows and “Select” buttons.
Unit’s LCD display stays black until power cord plugged into outlet and “Power” button pressed.
Once “Power” button pressed LCD display will lit up and display “stand by” message.
Press any button and LCD will display the following messages : “Initialization
completed. KD-MSCAT8x8 Master”. Status “Master” means that you ether operating a single
unit or it’s a controlling (master) unit in expanded configuration. Status can be changed to “Unit #”
for expanded configuration. “Master” will always be a first unit in expanded configuration, followed
by “Unit” 2, 3, 4, 5.
At this point only “Menu” button will be unlocked, thus prompting you to enter into Configuration/
Setup menu.
The following paragraph describes Menu navigation tree. (see also the diagram below)
Pressing “Menu” button will bring “Output setup” message on LCD display.
Pressing “Up” or “Down” arrows will rotate menu through the following main menu selections :
Output Setup ➔Input Setup ➔Control Setup ➔Expansion Setup ➔Control Setup
Pressing “Menu” button again will bring “Output setup” message on LCD display.
Pressing “Left” or “Right” arrows while on any of the above menu selection will move you through
Functions selection. For instance, pressing “Left” or “Right” arrows within “Output setup” will
rotate menu through the following functions:

Pressing “Select” button at this point will bring you to first function – Set Output.
Pressing “Up” or “Down” arrows while in Function menu will change the value assigned to the
Function – ether as a numerical (01, 02 e.t.c) or as a state (On, Off e.t.c)
Note: Each stand alone KD-MSCAT8X8 gives you a flexibility of selecting and switching 16 Audio
Inputs (8 Analog and 8 Digital). All 16 are fully independent and can be selected as Input to any
Output. Since the majority of installations would require switching of the same Input Video/Audio
combination most of the time, set up menu will allow you to set Video/Audio association in a such
a way that switching will be done in single command, thus reducing switching time and possible
errors. At the same time, Video and Audio switching can be done independently, providing greater
flexibility and extending range of applications in which KD-MSCAT8X8 can be used.

Hercules Expansion: Theory of Operation
At the time of this manual printing, the Hercules series KD-MSCAT8X8 Matrix Switcher is
expandable to as many as 40 configurable outputs in a block of 5 base units. This expansion
feature is factory installed and shipped to the consumer as a pre-wired and pre-tested combination
of two to five KD-MSCAT8X8 Matrix Switchers. The expansion packages are comprised of multiple
KD-MSCAT8X8 units ganged together. In the expansion configurations, the individual units are
connected by means of Expansion Slots via High-speed coax expansion cable.
Expansion can be done in the field as well by connecting additional units via High-speed coax
expansion cable and assigning proper numbers via Menu selections.
Typical Hercules KD-MSCAT8X8 Expansion Application Example
for a KD-MSCAT8X8-32X32:
Four (4) KD-MSCAT8X8 base units configured from the factory to provide
32x32 HDTV Matrix Switching
TCP/IP control
The KD-MSCAT8X8 HDTV Switcher can also be remotely controlled via TCP/IP protocol.
Static IP address and IP Mask updatable via Menu Control Setup function.
Default setting for the IP address is 192.168.000.233
Default setting for the IP Mask is 255.255.255.000
Fixed port setting is 23.
Full set of RS232 commands is available via TCP/IP protocol.

RS-232 Protocol and Commands
The KD-MSCAT8X8 HDTV Switcher can also be remotely controlled via its RS-232 port
by systems such as Crestron, AMX, ELAN, Control4 and others, utilizing industry standard
commands PROTOCOL:
57600 Baud rate
8 data bits
1 Stop bit
No parity
For the base KD-MSCAT8X8 HDTV Matrix RS-232 Control Switcher, you must supply
your own RS-232 cable and insert carefully in the back of the unit.
For the Hercules Expansions, your units come pre-configured from the factory with
their own RS-232 cable for you to use to connect to your PC or Control System.
RS-232 Connector type: DB-9 Female
Pin 2 = Tx, Pin 3 = Rx, Pin 5 = Gnd, Pin 4 = Pin 6, Pin 8 = Pin 7
Note: the pinout is with respect to the switcher, not the external controller.
The commands list for the KD-MSCAT8X8 HDTV Switcher is as follows:
Minimum timing interval between successive RS-232 commands is 0.2 sec.
Note: Exception is input switching commands. For input switching commands the minimum timing
interval between successive RS-232 commands is determined by the Fade-to-Black period set
via RS-232. The minimum period here is the greater of the two: 0.2 sec or Fade-to-Black interval.
Please see Fade-to-Back Interval Set for more information
