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 cor-
rect 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 fur-
ther degrade signal quality.
l
Signal strength? The use of cable joins, stranded patch panels, wall outlands and stranded patch leads as inter-
connects 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 ter-
minated 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.
IR CONTROL:
l
Are the IR emitters and receivers correctly positioned to allow infrared signals to be transmitted and received?
Emitters should be fixed firmly over infrared sensors of sources. Receivers should be attached to displays ensur-
ing a clear line of sight to the remote control used to operate. Each IR port has an LED, when correctly installed
the LED will flash red when IR is transmitting and flashes green when IR is being received
l
Is your remote control powered and sending a signal? As IR is invisible to the naked eye, check your remote is
transmitting a signal by viewing the remote handset sensor though a digital camera/camera phone. The sensor
should flash when a button on the handset is held down.
l
IR signal dropout can be experienced due to exterior emissions of infrared radiation. Ensure emitters and receiv-
ers are away from direct sunlight. Halogen lighting and plasma screens may also interfere with IR signals.
