TROUBLESHOOTING
Generally, the majority of HD distribution installation
issues are either caused by minor connection
errors, communication problems between devices,
or when the transmission of high signal bandwidth
is attempted using insufficient cable. Should you
encounter any technical difficulties when installing
and configuring the matrix, we are confident
solutions can be found by working through the
following troubleshooting checklist before seeking
alternative technical support.
No Picture or poor quality picture
1) Power
– are your HDBaseT transmitter or display
receiver baluns powered both ends? Transmitters and
receivers should have their own power source i.e. the 12v
power adaptors included with your baluns.
Note:
Receivers do not need to be independently
powered if part of an HDBaseT extender set – there is a
two core power link between transmitter and receiver that
powers the receiver at the display end.
Are all sources definitely powered and firmly connected?
2)
It is highly reccomended to always use test equipment
prior to installation and to troubleshoot any problems.
3)
Check display device supports HDCP, is switched to
the correct source input mode and is compatible with the
receiver - if any issue is suspected, replace display device
with another model.
4) Distance –
Is the cable too long for the signal to
be transmitted effectively? The HDBaseT classification
used within the transmission device and RX-70-PP allow
transmission of 1080p up to 70m/230ft. Ensure the cable
distance matches the project requirements and is well
within the maximum transmission distance of the signal.
5) Cable joins?
Joins in your cable run can impact on
signal strength, resulting in reduced transmission that may
manifest itself in poor picture quality or a complete lack of
picture.
6) Cable Choice and Signal Reduction –
Are stranded
patch leads being used as interconnects between patch
panels or wall outlets? CCA (Copper Clad aluminium)
cables being used? These can reduce transmission
rates by up to 40% – we recommend solid core straight
11. Troubleshooting
through with minimum connections used wherever
possible.
7) Resolution
– If you reduce the resolution of the
source, do you get a picture? If so, this suggests a
discrepancy between source and display resolution or
a bandwidth capacity issue with your cable. Check that
your inputs and outputs share the same resolution and
that the signal is being successfully transmitted along your
cable run.
8) Correct connection
– It may seem obvious but
double check all UTP, HDMI, power and IR cables are
connected to the correct ports.
Note: Even a fraction off can be the difference
between a perfect picture and a blank screen.
Double check all connections are firmly made in the
correct ports.
9)
C
heck LED indication on Receiver for confirmed
operation.
Are LEDs lit and/or behaving properly (static
or flashing - see Panel Description for details on LED
indication). If LEDs are not correctly lit, connections,
cable/terminations, interference , distance etc. should be
investigated. Swap cables out if necessary.
10) Cable wired to 568B standard?
Is your cable wired
and terminated correctly and are those terminations
connected to the correct ports?
11) Electrical interference –
HD transmissions are
susceptible to electrostatic interference so locations of
cables and devices should be considered
HDBaseT technology is more resistant to interference
compared to regular transmissions but care should still be
taken during installation - could any form of interference
be generated? If so, attempt to remove the source of
electrical interference or move the cable run to decrease
the effects of the interference.
12) Is a picture achieved when connecting the
source directly to the display?
If not then the problem
could lie with the input or output device rather than the
means of distribution i.e. the display rather than cable,
matrix or receiver itself.
13) HDMI lead condition and quality
– HDMI cables
and connectors are delicate and can be easily damaged.
Furthermore, lead quality varies dramatically, particularly
in lower price brackets. Swap your HDMI leads for high
speed rated HDMI cables and check operation. If in
