Model # KD-DH12
Key Digital “Digital Magic” (Model KD-DH12) is a state-of-the-art ATSC Set Top Box that scales to your display’s native resolution and distributes
the Video and Audio to up to 12 displays.
Why you need Digital Magic, Model # KD-DH12
Key Digital engineered Digital Magic (Model # KD-DH12) as a simple, convenient, yet high-quality solution for applications where you have RF
Inputs that need to be decoded, scaled, and distributed to an array of displays. Digital Magic offers just what the retail outlets, hotels, casinos,
and even high-end custom home theater installers are looking for -– a unique “one-stop shopping” solution for applications where you need to
decode off-the-air or Cable (RF) ATSC & NTSC, or 480i baseband (YPbPr & CVBS Composite Video) input signals, scale them to your display’s native
resolution, and then distribute them to up to 12 displays.
Since it is a Set Top Box that decodes ATSC and NTSC, you can route just ONE RF off-the-air or Cable feed run throughout your facility, and input it
directly to Digital Magic. Digital Magic then takes over as an ATSC/NTSC decoder, and can even scale the source to match the native resolution of
your display. For example, Digital Magic can down-convert your 1080i input video to 480i, or up-convert your 480i inputs to 480p, 1080i, or 720p.
The high-quality scaler, equipped with Key Digital’ advanced, motion-assisted de-interlacing algorithm called “Clear Matrix”, lets you up-, down-,
and cross-convert the input to your display’s native resolution. Digital Magic supports output formats of 1080 interlaced, 720 progressive, and
480 interlaced and progressive; 60 Hz output refresh rates; and aspect ratios in and out of 16:9 and 4:3.
Digital Magic has 12 discrete Distribution Amplifier (DA) outputs selectable between Component Video (YPbPr) or Composite Video (CV, or “CVBS”).
All of the outputs will display the same resolution and in the same mode (Composite or Component Video). Digital Magic also handles your audio
requirements, with analog (Left & Right stereo pairs) and digital PCM audio supported at the input, and distributed to the discrete outputs. You
can literally run just one RF/Cable feed into Digital Magic, and then drive an entire array of displays (up to 12 without the need for an additional
DA). Since Digital Magic has a front-end tuner, you can have multiple programs even on your internal cable network, and feed several Digital Magic
units tuned to their respective channel. For retailer demo room applications, you can readily add channels without the need for additional wiring.
And there is no need to route multiple YPbPr cable feeds, except from the very output of the built-in Digital Magic DA to your actual display devices.
With its user-friendly On-Screen-Display (OSD), programmable IR remote with “hot” buttons (discrete IR commands are available), and user-selectable output resolutions and aspect ratios, Digital Magic is easy to control and operate. It is rack-mountable (2RU), has no fan noise, and is easy
to install and integrate into your system. The RS-232 port is equipped with discrete command protocol compatible with all control systems (like
Crestron, AMX, CNMSX-PRO), and is even designed to allow customers to upgrade firmware over the Internet.

OPERATING INSTRUCTIONS
QUICK SET-UP
Connecting and using your Key Digital Digital Magic (Model # KD-DH12) combination Set Top Box, Scaler, and Distribution Amplifier is a simple
process.
Become familiar with Digital Magic. Your KD-DH12 Digital Magic package includes the following items:
• One Digital Magic unit
• IR Remote Control with 2 AAA batteries included
• Standard power cord
• Rack mounting hardware: brackets, screws, and clips
• This Operating Manual
• Warranty Registration Card
Determine your particular application requirements. A typical application for Digital Magic is in a retail store where you have an off-the-air or
cable NTSC/ATSC feed that you want to decode, scale to the native resolution of the displays you are demonstrating, and then distribute the A/V to
up to twelve displays. With Digital Magic, you have all of these capabilities in one convenient package, and with a minimum of cable routing.
Some typical Application Examples are depicted in the figure below.
When considering the type of configuration you require, you’ll need to know if you have RF inputs (like off-the-air or cable, where Digital
Magic can support two independent inputs), or 480i Component Video (YPbPr) or baseband Composite Video (CVBS) Inputs (Digital
Magic can support either). On the output side, you’ll need to know if you are driving all Component Video (YPbPr) displays, or Composite
Video (CVBS) displays. As well, the audio I/O can be analog stereo Left & Right, or digital PCM. Remember, each of the outputs of the
Distribution Amplifier will share the same properties and resolution, as configured by the user.
Connect the A/V Inputs and Outputs to suit your particular configuration. First, become familiar with the I/O panel, which is at the rear of Digital
Magic.

*Note: CV = Composite Video, or CVBS
In addition to the above connectors, the Input Group also includes two female F-type connecters for your RF input, labeled “Ant A” and
“Ant B” and may also appear correspondingly as “Ant 1” and “Ant 2” in some versions of the OSD menu.
Place the unit in a convenient location. This is a good time to rack-mount your Digital Magic unit, with the 2 RU mounting hardware included.
Rubber feet also allow you to place the unit on a counter. Note that the top of the unit has openings in the grate which you should keep unobstructed to permit air-flow to the power supply and the rest of the unit. Also, do not obstruct the IR path (a red lens on the right side of the front
panel).
Make the final connections. Be sure to connect the power cord to the rear of the unit and to a standard wall outlet. You may also connect the RS232 port to your Home Theater Automation System (like Crestron, AMX, or CNMSX-Pro), or in the future use this port with your personal computer
for Digital Magic firmware upgrades.
Please see the Appendices at the end of this manual for instructions on using the RS-232 port for firmware
upgrades and external control of your Digital Magic unit.
Learn to operate the unit with its user-friendly OSD and controls. You can use the Remote Control or use the Pushbuttons on the front panel of
the unit. A front-panel LCD also displays the current channel number (for RF inputs) or the status of the unit during menu manipulation. See the
section below for a more detailed description of the easy navigation / control of your unit and user-friendly On-Screen Display (OSD) menus.

OPERATING INSTRUCTIONS
NAVIGATION / CONTROL
It is most convenient to operate your Digital Magic with the Remote Control provided with your unit. However, you also have the option to go directly to the front panel and use the front-panel Pushbutton switches. It is recommended that you first learn the basic function of the Remote Control
and front-panel Pushbuttons / LCD. Then, a more detailed description of the actual OSD menus and set-up / control of Digital Magic will follow.
Navigation / Control: before you go through the OSD menus, first become familiar with the Remote Control, front-panel Pushbuttons, and frontpanel LCD status display.
First follow the Quick Set-Up instructions provided in this Operating Manual to physically connect Digital Magic into your system. Then, apply
power to the unit and batteries to your Remote Control, and turn the unit “On” with either the front-panel Power switch on the far left, or the red
POWER switch on the Remote Control. The LCD display will indicate the power-up status. The Power switches toggle the unit On/Off.
Next, you will start “Navigating” and “Controlling” your Digital Magic unit, with either the Remote Control or the front-panel Pushbutton switches. As
you Navigate and Control, you will receive feedback through the front-panel LCD display. Much more detail is provided via the OSD that will appear
on one of the displays connected to any of the Digital Magic outputs, described later.
Bring up the OSD Menu on your output display by either:
• Pressing the MENU button on the Remote Control.
• Pressing the Menu Pushbutton on the front panel of the unit.
Learn the basic operation of the OSD menus. Once you bring up the main Menu, push the Navigation
arrows on the Remote Control or four front-panel pushbuttons, as follows:
• Pressing the Down and Up arrows allows you to scroll within the menu through
the different options. For example, if you are in the “Video” menu, you can scroll
through the main Video functions, like “Aspect (Ratio) Control” or “Resolution”.
• Pressing the Left and Right arrows allows you to go to the next logical “level” of
the menu. For example, if you are in the “Video”/”Resolution” menu, you can then
press “Right” to bring you to the next level of the menu, namely the various
Resolution options, like 1080i, 720p, 480p, or 480i. Then, press Down and Up
arrows to scroll through the resolutions until you have reached the desired one,
such as 1080i.
• When you are in a Menu and have reached your desired selection, such as in the
“Video”/”Resolution”/”1080i” example, then press the Select (front-panel) or OK
(Remote Control) button to make and store your selection.
• When you are completed with your set-up, you can press Escape (front-panel) or
EXIT (Remote Control) to remove the OSD and resume normal viewing.
• Normally when the unit is ON and you are not navigating, the LCD will display the
Channel Number.

• INPUT [Select Antenna A/B (1/2), Component, or Composite Video In]
You may also use the lower half of the Remote Control unit to select the channel number and add/delete channels to your “Favorite”
channel list.
Learn the “Hot” buttons on the front panel.
• Note the Resolution Pushbutton on the right side of the front panel. By pressing this button and observing the LCD frontpanel display, you can cycle through the various output resolution options available, namely 1080i, 720p, 480p, or 480i. This
is a particularly useful feature in the event you use the front-panel navigation to select an output display option that is not
compatible with your current display device, and you “lose” the OSD feature. Simply press the front-panel Resolution button
and you will be prompted as to wheter you want to change the display resolution [Yes or No]. If you select “Yes”, continue to
press the front-panel Resolution pushbutton as you cycle through the different resolution options, stopping on a desired one
that is compatible with your display device, as noted on the front-panel LCD.

APPENDIX A
Upgrading Digital Magic (Model # KD-DH12) Firmware
From time to time, Key Digital may offer firmware upgrades for Digital Magic. These upgrades will enhance the operation of your Digital Magic
unit, and are easily installed by connecting the RS-232 port (D-sub, 9-pin female connector) on the upper-left rear panel of your Digital Magic unit
to a desktop or notebook PC using a standard RS-232-cable. The files you will need to perform any upgrades are available via e-mail by contacting
us at tech@keydigital.com, or you can download them from our Key Digital web site at http://www.keydigital.com/downloads/DH12upgrade.zip
Once you have downloaded the necessary executables and firmware upgrade files from our Key Digital web site onto your computer, please follow
these simple steps for Firmware Upgrade using the Flash Manager:
With your Digital Magic unit in the Power-OFF condition, connect the RS-232 port of your Digital Magic unit to the COM port of your computer using
a straight RS-232 cable (not a null modem cable).
Execute “flashman.exe” on your PC and select a COM port (COM1 or COM2). If you select an occupied COM port, an error message will alert you to
close the program and execute it again.
Press the [LOAD] button and select the binary file (“flash_xxxx.bin”). If the file is loaded correctly, the program will display a check sum value
that must have the same value as in file name.
Press the [PROGRAM] button ( “Looking for a STB connected... “) and press the POWER button on the Digital Magic front panel (Power-ON). If the
download process is proceeding properly, a message will advise you of the download progress. The download process may take up to 8 minutes
— please wait for the entire download to complete, and do not disrupt this process.
NOTE: If the “flashman.exe” does not execute properly, then repeat the steps 2 – 4 above. The “flashman.exe” generates a
“flashman.cfg” file in the first execution. If the download message does not appear, try powering OFF and ON your Digital Magic unit.
If the download has been successful, the “All Programming Done” message will appear. At this time, Power OFF your Digital Magic unit. Then, close
the Flash Manager program and again turn ON the Power to your Digital Magic unit, execute the “FACTORY DEFAULT” in the menu function, and
check the unity.
It is now a good idea to check the basic operation of your Digital Magic unit to be sure that it is working properly and the upgrade was indeed successful. Should you encounter any problems during or after your firmware upgrade procedure, call us toll-free at 1-866-780-5069 or contact us by
e-mail at tech@keydigital.com.

Controlling Digital Magic (Model # KD-DH12)
from your Home Theater Automation System
For integration with your existing equipment, your Digital Magic unit can be conveniently controlled from your existing Home Theater Automation
System (like Crestron, AMX, or CNMSX-Pro) by using the discrete command protocol. You will need to locate the RS-232 port (D-sub, 9-pin female
connector) on the upper-left rear panel of your Digital Magic unit, and connect it to your Home Theater Automation System using a standard RS232-cable. You will be able to use your existing Home Theater Automation System to control the following Digital Magic functions:
Input select
Tuner channels Up and Down
Channel ##-# select
Aspect Ratio
Output resolution
Output format
Following is an example of how to use a communication program (such as Hyper Terminal) to generate the commands to control the above functions of your Digital Magic unit using the discrete command protocol:
With your Digital Magic unit in the Power-OFF condition, use a straight RS-232 cable (not a null modem cable) to connect the RS-232 port of your
Digital Magic unit to the RS-232 port on your PC. Use the following settings:
Set the Hyper Terminal to COM1*
Baud Rate: 57600
Data: 8-bit
Parity: None
Stop: 1 bit
*Note: make sure you are not running any other active program using COM1, such as the “Hot Sync” Palm program
Turn ON the Power to your Digital Magic unit. In your Hyper Terminal window, press [ENTER]. You will be prompted with:
Key Digital Digital Magic RS-232 control
DH12>
The help menu and the rest of the commands should be very simple:
Input select
Tuner channel Up and Downs
Channel ##-# select
Aspect Ratio
Output resolution
Output format
Note that in RS-232 command mode, the Digital Magic Remote Control and front-panel Pushbuttons are non-functional.
If at any time you want to escape from the RS-232 command mode, type “exit” on your terminal and press [ENTER].
