MAINTENANCE
Our PP and HDBaseT matrix range (Cat 5e/Cat6) has IR
pass-through from each of the outputs and has discrete
IR outputs at the switch end, meaning you can have
multiple identical sources yet the IR would be routed only
to the applicable source.
Do I need power at the TV end?
No. Our RX-70-IR-POH HD display adaptors require
no power supply at the TV end. To operate, the PoH
receivers draw the power from an PoH matrix or PoH
Transmitter. NON PoH devices require 5v. It’s important
that these are powered locally and do not receive remote
power from the rack as there can be issues resulting from
voltage drop along the length of cable.
For non-PoH products, our USB to 5v power cables
overcome the problem of having a second mains outlet
behind the TV. These useful leads draw power from
the USB port of the display to power the receiver, this
also means that the receiver is only powered when the
display is on making the system more energy efficient and
environmentally friendly.
Are WyreStorm products compatible with HDMI 1.4?
HDMI 1.4 refers to a list of ‘features’ that a device is
capable of supporting, including Ethernet channel, return
audio channel, 3D etc. Due to the continuously evolving
nature of the technology, HDMI Licensing LLC have now
decided to simplify terminology by testing and referring to
cable in terms of STANDARD or HIGH-SPEED rather than
in generations 1.3, 1.4 etc.
• STANDARD (or “category 1”) HDMI cables perform
at speeds of 75Mhz or up to 6.75Gbps, which is the
equivalent to a 720p/1080i signal – These HDMI cables
are NOT recommended.
• All WyreStorm equipment support HIGH-SPEED
(or “category 2”) HDMI cables that have been tested
to perform at speeds of 340Mhz or up to 10.2Gbps,
which is the highest bandwidth currently utilised over
an HDMI cable and can successfully handle 1080p
signals including those at increased colour depths and/
or increased refresh rates from the Source. High-Speed
cables are also able to accommodate higher resolution
displays, such as WQXGA cinema monitors (resolution of
2560 x 1600).
What about screens with different resolution
capabilities?
When sending a signal point to point a TV will
communicate it’s capabilities to the source, then the
source will output a suitable signal that compatible (i.e.
1080p Stereo audio).
If you were to use a matrix switch with three 1080p
screens and one 1080i screen, the resultant image would
be1080i across all screens. The matrix switches do not
scale per output but instead negotiate with the source a
signal that all screens are capable of supporting.
How does the Matrix cope with HDCP?
HDCP (High Definition Copyright Protection) is a feature
built in to HDMI devices to prevent theft of or illegal
distribution of HD content.
Unlike competing products, WyreStorm matrix switches
are legal and comply with HDCP regulations. They do
this by assigning a “key” to every display connected
to the switch. HDCP “keys” are assigned to a display
when connected to a HDMI device normally. This doesn’t
change when connected to a switch; it just assigns more
of them.
I can get 1080i but not 1080p at a TV location
Firstly ensure that both the source is capable of outputting
1080p and that the TV is Full HD 1080p screen. If this
is the case then the AMP, display receiver or PP Matrix
may require EDID management setting up using the DIP
switches. This useful feature provides a successful “send
and receive” to ensure swift and stable EDID negotiation
between the source and display. See Troubleshooting
section for more tips on problem solving.
I cannot get a signal from my A/V receiver along a
Cat 5e extender set
Check to ensure that the A/V Receiver isn’t adding CEC
(HDMI Control Protocol) to the outgoing signal, this can
sometimes have an effect on the HDMI signal.
19. Maintenance
Clean this unit with a soft, dry cloth only. Never use
alcohol, paint thinner or other harsh chemicals.
