Usage Modes

Quick Setup Guide

CONNECT:

1. Begin with the KD-FIX418A-2 unit, input and output devices turned off with power removed
2. Connect your HDMI source to KD-FIX418A-2’s input port
3. Connect your HDMI display to KD-FIX418A-2’s output port
4. Connect analog and/or digital audio outputs to amplifier, DSP, AV receiver, or sound bar
5. Screw-in the power supply to KD-FIX418A-2, then, plug-in to power outlet
6. Power on input and output devices

CONFIGURE:

• Use the EDID rotary to choose the desired video resolution and audio format.
• Use the Forced Hot Plug Detection switch to set the HDMI connectivity voltage to a high state.
• Use the 4K to 1080p down-convert switch if integrating a 1080p display or projector in a 4K system.

See each section in this manual for more information on each setting.

Rack Mounting

In addition to mounting with the supplied L-Brackets, multiple KD-FIX418A-2 may be mounted in KD-SMS16 using the side mounting screws. KD-SMS16 is a mounting shelf for Key Digital units with side mounting screw spacing of 2.912”, 2.582”, or 2.252”.
Do NOT exceed 12 units as doing so will result in unit damage by overheating.

Connections, LEDs, Slide Switches, and Rotaries

VIDEO INPUTS AND OUTPUTS

HDMI Input:

• The HDMI input is located on the short end beside the power.
• Blue LED near the HDMI connector illuminates solid to indicate an active HDMI signal is incoming.

HDMI Output:

• The HDMI output is located on the short end between the audio de-embed ports.
• Blue LED near the HDMI connectors illuminates solid when Hot Plug Detection (HPD) is received from the display/output device and there is an active incoming HDMI signal.
• The LED will blink steadily when there is no HPD from the display but an active HDMI signal is incoming.

HDMI Input/Output Port Specifications:

• Supports up to UHD/4K @ 50/60 fps [4:4:4], 18Gbps signals
• See Supported standard 4K Video Formats table

• There are no volume or tone control features
• There are no DSP features

Service (Factory) USB:

• This port is for factory servicing only. Does not have standard USB functionality

EDID Handshaking Rotary:

EDID authentication is provided from the KD-FIX418A-2 to the connected input/source

• The EDID file (AKA “handshake”) is selected using the EDID rotary on the unit and provides a list of compatible video and audio formats as well as digital data, informing the source device what it should output.
• Most sources will comply with a new EDID file without a power-cycle, but devices do behaves differently
• Adjustments may speed up sync time during source selection.

Note : Default position is “0”

IMPORTANT: Please apply light pressure to the EDID rotary when making your selection.

Forced HPD Troubleshooting Tool:

In cases of many layers of connectivity or non-standard devices in-line, hot plug detection (HPD) may be lost or drop below standard levels, leading to the video source not detecting a display/sync device and not outputting a signal. A display device may also not detect a connected source in cases of failed hot plug detection.

• When ON, Hot Plug Detection voltage is fixed ON to the connected source, informing it that it always has a live sync/display to receive its signal
• Standard HPD behavior (bypass) when set to OFF position

4K to 1080p Down Convert Tool:

• When set to ON, KD-FIX418A-2 will down convert incoming 4K content to 1080p. All non-4K incoming content passes through without resolution conversion.
• When set to OFF, all incoming content passes through without resolution conversion.
