TROUBLESHOOTING AND FAQS
11. FAQs
3) Do all the local sources work through the AV
receiver?
Check the operation of each source individually.
Bandwidth
1) If using a graphics-based source (such as a PC/Mac/
media server), make sure the source resolution is set to
a maximum of 1080p, 50Hz. Higher resolutions available
for graphics-based systems require higher bandwidth
that may affect transmission of signals as well as
incompatibility with devices.
IR
1) Check emitters at the IR TX transmitter end
and receivers at the IR RX receiver end – are they
connected to the correct ports on the matrix and display
receiver.
2) Is the emitter correctly positioned on the source?
Fix the emitter directly over the infrared sensor of the
source and attach using the adhesive backing.
Note: Locate the infrared source sensor by using a
flashlight to find the sensor within the facia of the source
display. If necessary, secure the emitter over the sensor
with a small amount of contact adhesive.
3) Is the remote handset powered and sending a
signal?
Note: IR is invisible to the naked eye, so use a digital
camera/ phone camera to check the remote signal – point
the camera at the remote control when pressing a button.
The remote transmitter can be seen flashing to indicate a
signal being sent. Replace batteries if flashing is not seen
on the digital camera screen.
4) IR dropout issues can be due to exterior influences
emitting infrared radiation that can interrupt IR signals.
Ensure emitters and receivers are away from the following
causes of IR interference.
• Direct sunlight, Fluorescent lighting (on cold start up)
• Halogen lighting
• Plasma screens
5) UTP Termination Issues – ensure cables and RJ45
terminations are correct and in good condition at
both transmitter and receiver ends to see if control is
established. If so, a possible re-termination of the cable
could remedy the problem.
6) Are WyreStorm emitters and receivers being used?
The use of third party products/magic eyes may not be
compatible. Always use WyreStorm components included
with your purchase or check compatibility of third party
control systems with your WyreStorm dealer.
7) If problems persist, swap out the IR emitters and
receivers to rule out faults with the units themselves. Use
emitters you know are fully operational to test working
condition.
8) Reactivate the IR call-back function on your matrix
and swap IR ports on the matrix to rule out a fault with
thematrix or connection ports.
9) Should IR remain unresponsive, turn off and disconnect
all cables from the matrix and reconnect zones one at a
time to assess if one location in particular is the problem.
If so, run new cables directly to the display – if this fixes
the problem, it is likely that electromagnetic interference /
damage to the cable somewhere along the run is causing
the IR signal to drop out. Investigate and remove EM
interference from the run or replace damaged UTP cable.
Cat5e or 6?
While our equipment is tested and graded to Cat 5e
cable standard; tests have shown that better results
are achieved when using Cat6 cable. The lower AWG
(American Wire Gauge) uses thicker copper cores ensure
better signal transfer/Transmission rates. Newly installed
cabling should always conform to Part P Regulation and
BS 7671 (17th Edition), and should be terminated to 568B
standard.
Can I use a single Cat 5e/Cat 6 cable?
Although conventional transmission used to be
considered two Cat5e cables for video, audio and control,
HDBaseT transmission only requires a single cable.
All features found with dual cable transmissions are
supported with HDBaseT, with addition of RS232 serial
control, Power and Ethernet passed along a single
Cat5e/6/7, depending on feature set/model of product
How far can the signal travel?
Under perfect transmission conditions WyreStorm
HDBaseT receivers will operate at 50m, 70m or 100m
(@1080p) depending on the model used.
Perfect conditions denotes no electrical interference,
straight cable runs with no bends or kinks and no patch
