1-1 Package Contents

Please make sure all of the following items are included in the package:

1. DD-120 Unit
2. DC 5V 2A Power supply adapter

1-2 General Specification

PureLink DD-120 distribution amplifier is designed to distribute a single PC digital signal into multiple monitor without any degradation of original signal quality or distortion of the image. In addition, a dedicated IC chipset makes DD-120 capable of amplifying and distributing highest quality of video signal and true HD digital contents.

DD-120 is compact, durable and low power consumption design makes it ideal solution for connection for high definition video and audio signal of digital display device, such as LCD, Plasma, LED, Projector, and etc.

In addition, DD-120 offers quick and easy plug and play, installation for commercial or residential system.

1-4 Main Features

1. High Quality Picture - No Signal Loss and Digital Noise Free Our Distribution Amplifiers are built to deliver the highest quality picture preserving the native resolutions of the video sources without any signal loss. At the same time, the digital noises that may affect the picture quality will be eliminated. Due to the nature of the digital signals and passing through multiple stages of connection when using distribution amplifiers, it is important to eliminate the digital noises and boost the signal strength to preserve/enhance the video signal quality.
2. Signal Amplification for signal reliability and long length signal transmission Our 5V power adapter supplies adequate power to amplify the video signals from the video source. This is necessary as the overall length from the video source to the displays is longer when using the distribution amplifiers (distance from the video source to the distribution amplifier + distance from the distribution amplifier to the display). In most cases, the overall distance that the DVI signal will need to travel is over 10ft. Due to the nature of DVI signals, amplification is necessary to warrant the video quality and reliability. (Without amplification, there may be occasional blackouts or blinking effects) With this amplification feature, your video display can be extended up to 2300ft using our fiber optical DVI cables.
3. HDCP (High-bandwidth Digital Content Protection) Compliant Our DVI distribution amplifiers are fully HDCP compliant. Many video sources such as DVD players and Satellite/Cable Receivers are HDCP encrypted. For these video sources to be displayed correctly, HDCP compliant devices (e.g., TV, DVI Switch, distribution amplifier) are required.

Video Connection

1. Turn off the whole system before connecting.
2. Connect your video source’s DVI output port to the DD-120’s DVI input port using standard DVI cables (not included).
3. Connect your DVI display’s DVI input port to DD-120’s DVI output port.
4. Plug the 5V power supply to DD-120
5. Plug the 5V wall mount power supply into the wall outlet.
6. Turn on DD-120
7. Turn on your monitor
8. Turn on your video source.
9. Output# 1 and #2 status light will be lit if everything is properly installed.

PureLink DD-120 is capable of capturing and storing EDID of the monitor that is connected to DD-120. It is essentially important that source graphic adapter must recognize and understand the EDID of the connected monitor correctly in order to describe supported display mode to graphic adapter. Please follow the next instruction of how to save EDID on DD-120

1. Connect a monitor to output # 1 of DD-120
2. EDID indicator light will blink about 2-3 times, if EDID is successfully saved.
3. Please note that EDID indicator light will blinks 5-6 times, if EDID writing is failed. In case EDID writing fails, you should check your physical connection.
4. Reboot DD-120 for the change to take effect.

Note: Please note that a factory default EDID is set to WUXGA resolution. Thus you need to save the EDID before you turn your system on.
