Please read all instructions to insure safe operation of the product.
* Note that when used with the KD-CAT5XHDMI,
the PCM input port of the KD-HDMIWPTX is
not available on the receiving KD-CAT5XHDMI

Installation Instructions
The KD-HDMIWPTX can receive power from either the HDMI connection or via the
supplied power adapter. When using the HDMI cable to deliver power to the unit,
performance is subject to the following factors:
Ability of the HDMI source to deliver the required power over distance
Quality of the HDMI cable.
1. Find a safe and convenient location for the KD-HDMIWPTX unit.
Before permanently securing the unit or final installation of cabling
behind walls or ceilings, test for proper operation of the unit and the
cables in your system.
2. Power.
In order to insure the best possible performance from the KD-HDMIWPTX, use
only the original Key Digital power supply. If you are using the supplied power
adapter, plug it into the power input jack on the side of the unit. You should see
the “Power” LED illuminate. (see Fig. 1)
3. Connections.
Plug in the HDMI source cable to the “Input” port on the front of the KD-
HDMIWPTX. If you are not using the supplied power adapter, the “Power” LED
should illuminate upon plugging in the HDMI input cable if your HDMI source is
powered on.
If it is necessary to use a separate PCM feed from the source, connect it to the
PCM input port on the front of the KD-HDMIWPTX.
Plug in the CAT5 cables to the output ports on the back of the KD-HDMIWPTX.
At this point, if both your source and destination (KD-CAT5XHDMI, KD-CAT5XCAT5)
devices are powered on, you should see the green “Power” LED and the blue
“HPD” LED lit.
The HDMI CAT5 signal is split into ‘Data’ and ‘Control’ outputs. Verify that these
outputs feed the corresponding ‘Data’ and ‘Control’ inputs on the receiving device.
The CAT5 outputs can feed either the KD-HDMIWPRX or KD-CAT5XHDMI*
(receiver) to convert back to HDMI. Additionally, they can feed the KD-CAT5XCAT5,
which is a CAT5 extender, to make longer CAT5 runs more reliable.
* Note that when used with the KD-CAT5XHDMI, the PCM input port of the KD-HDMIWPTX is not available on
the receiving KD-CAT5XHDMI

When a stable signal is established between your source and destination,
the red “Equalizer Active” LED will light. If this red LED indicator is blinking or
not illuminated, try shortening HDMI or CAT5 cable lengths or lowering the
resolution of the video signal.

DVI applications for the KD-HDMIWPTX
The KD-HDMIWPTX can also be used to extend DVI video cable runs. For these
applications, use DVI to HDMI (Key Digital model number KD-MFHDMI) adapters to feed
the HDMI input of the KD-HDMIWPTX.
Mounting the KD-HDMIWPTX unit
Before permanently securing the unit or final installation of cabling
behind walls or ceilings, test for proper operation of the unit and the
cables in your system.
The wall plate can be mounted in a standard electrical box.
Remove the white, plastic face plate on the KD-HDMIWPTX
Connect CAT5 cables to the appropriate CAT5 ports on the back of the KD-
HDMIWPTX.
Secure the KD-HDMIWPTX metal bracket to the electrical box using the screws
supplied with the electrical box.
Re-install the plastic face plate on the front of the KD-HDMIWPTX
Secure the metal cable tie bracket to the face plate using the supplied screw. This
bracket provides a method for securing HDMI cables to the wall plate with a single
cable tie.

Troubleshooting
Most issues with the KD-HDMIWPTX setup will involve resolution and distance
performance. If you experience problems (no image, video artifacts, picture dropout,
noise) here are a few things to try.
Use the shortest possible HDMI and CAT5 cables between devices.
Lower the output resolution of the image source.
Use the provided power supply for the KD-HDMIWPTX instead of relying on the
voltage in the HDMI cable to power the unit.
Use Key Digital
®
HDMI cables.
Other possible problems can result from custom made CAT5 cables. CAT5 cables must
be terminated in accordance with TIA/EIA-568-A or TIA/EIA-568-B pin-pair assignments.
