An optional HDMI cable clip (included) enables a method for
securing HDMI cables the KD-CATHDX units and helps
defeat intermittent or complete signal loss due to poor
connection.
DVI applications for the KD-CATHDX
The KD-CATHDX can also be used to extend Digital DVI cable runs.
➔
For the applications, use appropriate Dual Link DVI to HDMI adapters.

Link Lights
To achieve solid Link Lights on the KD-CATHDXTx and KD-
CATHDTXRx baluns, all connections must be solid and properly
synced. This includes the HDMI connectivity between source and
KD-CATHDXTx balun, Data and Video/Audio CAT5e/6 connectivity
between KD-CATHDXTx and KD-CATHDXRx baluns, and HDMI
connectivity between KD-CATHDXRx balun and display.
Extending Control Signals with KD-CATHDX
KD-CATHDX baluns can be used to extend bi-directional IR signals or uni-directional
RS-232 control. Use the 3.5mm mono mini connection on the KD-CATHDXTx and
KD-CATHDRx.

Troubleshooting

Most issues with the KD-CATHDX 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.
1. Use the shortest possible HDMI and CAT5e/6 cables between devices.
2. Lower the output resolution of the image source.
3. Use Key Digital HDMI cables.
®
4. Re-terminate CAT5e/6 cabling.
CAT5e/6 Splicing
Do not use patch panels, punch downs, keystones, wall plates, or
splicing of the CAT5e/6 cables at any time.
