Troubleshooting
The troubleshooting section can be used on all Pulse-Eight Video Matrix & Extender products.
Should you encounter installation difficulties or issues with device communication, the following
checklist of common issues and causes should help resolve your issues. If you still continue to
experience issues, please contact your place of purchase.
NO OR POOR PICTURE QUALITY:
Connected and powered? Double check all HDMI, CAT and power cables are firmly connected into the
correct ports an all devices are correctly powered.
l
Connected and powered? Double check all HDMI, Ethernet and power cables are firmly
connected into the correct ports and all devices are correctly powered.
l
Cable length? Are you approaching the maximum distance of the cable (70m) if so, adjust the
picture quality or try using an additional extender kit to go further distance. Cables bundled
together may cause cross talk and further degrade signal quality.
l
Signal strength? The use of cable joins, stranded patch panels, wall outlands and stranded patch
leads as interconnects between them can significantly reduce signal strength. Use solid core
straight through connections wherever possible.
l
If you reduce the resolution of the source do you get a picture? If so, this suggests a conflicting
resolution between source and display or a bandwidth capacity issue with your cable. Check all
inputs and outputs share the same resolution capabilities.
l
Picture 'snow' / HD 'noise' signifies a failure to fully establish a signal and can often be caused by
poorly terminated RJ45 connectors or excess cable lengths. Ensure your cable is correctly wired
to 568B standards.
l
Pink or off-colour picture? This could be caused by an invalid EDID or the source device failing to
read the EDID from the matrix. Try re-booting matrix and all source devices to force the re-reading
of the EDID.
l
Cable quality and condition - HDMI cable/connectors can easily be damaged and the quality of
material can vary, Always use good quality leads and cables and try swapping cables that are
known to be working into the solution to see if this improves your image.
