Troubleshooting - Wyrestorm eX-35-4K Instruction Manual

2
Connect a Serial-to-USB cable from the RS232 port of the unit to a computer and run VS010 R X Firmware
Update batch file.
3
Once the update has been completed, be sure to return the MODE switch to the NORMAL position for RS232
control signal transmission to be passed.
NOTE Connect RS232 cables to the RS232 port of the unit to form one extension cable.
!
Ensure the RS232 MODE switch on the unit is returned to NORMAL after updating. Although the
extenders will transmit audio/video signals in NORMAL or UPDATE settings, RS232 control between the
devices of will not be possible when the switch is set to UPDATE mode.

Troubleshooting

Generally, the majority of AV 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 – is your Transmitter and Receiver powered
with correct LED indication?
The EX-35-4K features PoH to remotely power the
Receiver from a mains powered Transmitter, so no
additional power supply is required at display locations –
Please use power supply included.
2) If possible, 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 transmitter and EX-35-4K allow transmission of
4K up to 35m/115ft and 1080p up to 70m/230ft. Ensure
the cable distance matches the project requirements and

is well within the maximum transmission distance of the
signal.
Note: If approaching the limits of the transmission
capabilities, transmission should be extended by using
another extender set to ensure the signal reaches its
destination effectively.
5) Cable Joins – Joins in the cable run or RJ45
connectors can impact on signal strength, resulting in
reduced transmission that may manifest itself in incorrect
picture quality, picture dropping out 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
through with minimum connections used wherever
possible.
7) 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.
8) Check LED indication on Receiver for confirmed
operation. Are LEDs on and/or behaving properly (static
or blinking - 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.
