KD-HDMI2x1 & 4x1 Operating Instructions
KD-HDMI2x1 & 4x1 Operating Instructions
Getting started
2. Connect your HDMI sources to the input ports of your KD-HDMI unit.
Your KD-HDMI switcher by Key Digital® is easy to configure and operate. In this section, you will first connect all of your video and audio input and output devices to your KD-HDMI unit. These are the topics covered in detail in this section of the Operating Manual that you must follow for the proper installation of your KD-HDMI unit: 1. Find a safe and convenient location to secure, mount, or place your KD-HDMI unit. 2. Connect your HDMI or DVI-D source devices to the input ports of your KD-HDMI unit. 3. Then connect your HDMI or DVI-D Displays to the output ports of your KD-HDMI unit. 4. If you do not plan on using the audio available from your sources over the HDMI link, then connect your audio sources to the RCA and/or Toslink input ports of your KD-HDMI unit. 5. Connect the Control inputs to your KD-HDMI unit, if desired. 6. Be sure the Operation Mode Switch is set to the “Normal” position. 7. Finally, connect the power supply provided with your KD-HDMI unit.
1. Find a safe and convenient location for your KD-HDMI unit. Convenient mounting flanges are built into the unit. Use proper care to secure the unit to walls or other surfaces, using appropriate anchors and/or mounting hardware [not included with your unit].
A KD-HDMI unit dissipates power during normal operation, thereby it is recommended to leave enough ventilation space to provide sufficient airflow and cooling, especially if you are going to leave the unit “On” most of the time. Be sure to allow sufficient airflow, and do not cover the ventilation openings on the side of the unit. Before final installation of cables behind walls or ceilings, and permanently securing the unit, it is recommended to test for proper operation of the unit and cables in your system.
Important notes about digital Cables and Cable lengths: CAUTION: Always test first, before permanently installing the KD-HDMI Always test the picture quality, integrity of the connections, and overall operation before permanently installing any new component in your system, and especially before cables are pulled behind walls or ceilings. ➔ It is recommended that you always use high-quality HDMI (or DVI-D, if applicable)
cables, like those available from Key Digital. ➔ Limitations of the HDMI devices and/or the use of inferior cables may further restrict
the length of your cable runs. ➔ When using an HDMI cable extender, like the Key Digital® KD-HDB150, always
test first for proper operation and error-free picture & audio quality, and follow the instructions provided with the unit for proper installation and configuration.
KD-HDMI2x1_4x1_Manual.indd 8-9
Do not connect the external 5 Volt DC supply (provided) to the back of the KD-HDMI unit until ALL your video and audio connections to the KD-HDMI unit are complete
A typical INPUT PORT receives sources of HDMI video and a variety of audio options.

3. Connect your HDMI Display to the output port of your KD-HDMI unit. If the display you would like to connect to your KD-HDMI unit has only a DVI-D connector, then you can use a Key Digital® HDMI to DVI-D adapter at the KDHDMI output, followed by a DVI-D cable, to connect from the output of your KD-HDMI to the DVI-D input of the display. Note that while HDMI supports both video and audio over an HDMI cable, DVI-D supports video only and will therefore require that you connect any audio outputs separately.
4. Audio to your monitor is supplied over the HDMI link. If you choose to use another source or have a 5.1 surround sound system, the following information will help you set up your audio. If you are using the audio provided via the HDMI audio link only, then you may skip Step 4 and proceed to Step 5. In addition to the audio provided over the HDMI link, you have the following input options to the KDHDMI for audio sources [see note 1]: › Toslink optical audio inputs (Toslink connectors): ➔ A Toslink output is derived from one of the Toslink inputs as controlled via “Input Select” › Digital PCM audio inputs (white RCA female jacks): ➔ Available at the outputs of the KD-HDMI on the white [left] RCA female jack › Analog stereo left & right audio inputs (RCA female jack pairs: [white = left] & [red = right): ➔ Available at the output of the KD-HDMI on the RCA female jack pairs [1] The white [left] RCA female jacks are shared among these signals for each of the four separate output banks, so only one of these audio formats [Toslink optical converted to digital PCM, digital PCM, or analog stereo left & right] is possible at a time.
All audio inputs and outputs have color-coded RCA female jacks. For analog stereo audio, remember to follow and maintain the color code: [white = left] & [red = right]. Analog Audio Left &Right

6. Be sure the Operation Mode Switch is set to the “Normal” position. Once you have made all the video connections to your KD-HDMI, be sure the Operation Mode Switch located on the side panel of the unit is to the “Normal” position. The slide switch labeled “Operation” is a Mode Switch that must be set to “Normal” for proper operation of your unit. Only slide the switch to the “Mode A” position if you perform a Firmware Upgrade.
BASIC OPERATION This section of the Operating Manual guides you on how to use your KD-HDMI switcher with the front-panel pushbutton switches. LEDs are provided so that you can monitor your selections.
1. User Control. Since your switcher has multiple input sources for video and audio that may be switched to your display and audio system, you need to make the following selections: a) Select the input source that you want to send to your display and speakers (or audio system).
Slide the Operation Mode Switch located on the side of your unit to the “Normal” position for proper operation. Do NOT slide the switch to the Mode A position and apply power, or you may start an unwanted Firmware Upgrade of your unit. If you do so, immediately disconnect power from your unit and contact Key Digital®.
7. Finally, connect the power supply provided with your KD-HDMI unit. You MUST use the Power Supply provided with your unit or you VOID the Key Digital® Warranty and risk damage to your unit and associated equipment.
When all equipment is connected to your KD-HDMI and the Operation Mode switch is in the “Normal” position, you can now plug in the external 5 VDC @ 5 Amp Power Supply (provided with your unit) to the jack on the back of the unit. Then connect the power cord from the power supply into an appropriately rated wall outlet or power strip.
The KD-HDMI allows you to select an input source to be switched to your display. Because HDMI is has auto-sensing capabilities, your source device always knows the capabilities of your display. The selected source provides video and audio over the HDMI link. The selected input serves as the audio source. b) Select the type of audio you want to send to your speakers or audio system. Analog Audio Left / PCM
Analog Audio Right
Toslink Optical Audio
Different Color LEDs correspond to the selection of the input Switch Control.
Each of the HDMI input connectors has a hot-plug detect LED, as an indicator that there is an active HDMI source present at the connector.
Carefully insert the power supply connector to the back of your KD-HDMI unit.
The green LED used here indicates that an active HDMI link between the selected input source and the output HDMI sink (display) is established and is in progress.

Please review all steps first, before proceeding to upgrade your Unit. 1.
Make sure you have the required equipment for upgrade: a. PC with a serial port capable of 19200 Baud rate b. Straight male-female DB9 serial cable (Null-modem NOT supported) no longer then 10 ft. 2. Set the rear-panel Mode slide switch to “Mode A” mode. 3. Check our web site at www.keydigital.com for the latest firmware update ZIP file. Download and unzip the firmware ZIP file to any directory on your PC. All of the unzipped files that are created MUST be located in same directory on your PC. 4. Make sure that no devices are using the COM1 serial port on your PC. 5. Connect an RS-232 cable to the COM1 serial port on your PC, and the other end to the RS-232 port on the rear panel of the KD-HDMI unit. 6. Double-click the “HDMIxx.BAT” file. The command mode window should pop up. Use this pop-up window to monitor the progress of the Firmware Upgrade. 7. If an error occurs, check your RS-232 connection and repeat all of the above steps. 8. When the download is complete, disconnected the power supply form your KD-HDMI unit. The power supply MUST be disconnected (either from the back of your unit or from the wall outlet) to have a complete power shutdown - reset. 9. Disconnect the RS-232 cable between the unit and your PC 10. With the power disconnected, set the rear-panel Mode slide switch to “Normal” mode. 11. Reconnect the power supply to your KD-HDMI unit. The Firmware Upgrade is complete, and your KD-HDMI unit is ready for operation.

LEDs (light-emitting diodes) are like small light bulbs that light up to indicate a selection, and are used as status indicators. Pulse Code Modulation
RCA jack
PCM is a sampling technique for digitizing analog signals, especially audio signals. PCM samples the signal 8000 times a second; each sample is represented by 8 bits for a total of 64 kbps. Used in this Operating Manual to refer to digital audio. An RCA jack or what was called a “phono plug” is an industry standard audio connector used for the audio inputs and output of KD-HDMI units. The left [white] jack is used for the digital audio formats. Analog stereo audio uses both jacks, where white = the left channel, and red = the right channel.
SPDIF, S/PDIF
Sony/Philips Digital Interface
SPDIF (also written as S/PDIF) is a standard audio file transfer format, developed jointly by Sony and Philips corporations. S/PDIF allows the transfer of digital audio signals from one device to another without having to be converted first to an analog format.
Toslink™, Toslink
Toslink was originally created by Toshiba to connect their CD players to their receivers for PCM audio streams
Toslink™ (also written as TOSLINK™) is a standardized optical fiber connection system, most commonly used in consumer audio equipment to carry a digital audio stream between components.

HDMI to DVI-D Conversion
technical specifications
If a source or display you would like to connect to your KD-HDMI unit has only DVI-D connectors, then you should use Key Digital® HDMI to DVI-D adapters at the source output, followed by an HDMI cable, to connect that source to the HDMI connector inputs of your KD-HDMI. Note that while HDMI supports both video and audio over an HDMI cable, DVI-D supports video only and will therefore require that you connect any audio source separately to the KD-HDMI.
