Troubleshooting
Most issues with the PCBKDCATHD 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 CAT5/5e/6 cables between devices.
2.
Lower the output resolution of the image source.
3.
Use Key Digital
®
HDMI cables.
4.
Re-terminate CAT5 cabling.
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.
DVI applications for the PCBKDCATHD
The PCBKDCATHD can also be used to extend DVI video cable runs.
For these applications, use DVI to HDMI (Key Digital
®
model number KD-MFHDMI or
KD-FMHDMI) adapters.
➔
For DVI signals that do not carry HDCP, you may send video using a single CAT5/5e/6
cable that is input in the “Data” port of you PCBKDCATHD devices.
