Qs
5e 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 gauge, thicker copper
cores ensure better signal transfer. 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 cable?
Although conventional transmission is considered to be two
Cat 5e cables, it is possible to send the signal down a single
cable if necessary. All of our pro-matrix switches and UTP
splitters support single UTP mode, however in this mode IR
control of sources and matrix switching is not possible.
However using HDBaseT transmission; all of the twin cable
features are supported with the added benefit of Ethernet
and RS232 control.
How far can the signal travel?
Under perfect transmission conditions our HD receivers
will operate at 30, 50 or 100m (@1080p) depending on
the model used. Perfect conditions mean no electrical
interference, straight cable runs with no bends or kinks
and no patch panels or wall outlets. If some of the above
are factors in your installation then signal strength and
bandwidth can be compromised. If a cable run is reaching the
upper limit of the receivers’ capabilities, then the signal can
be boosted by way of an extender set (Rx-TX) or by simply
using an in-line repeater. Our transmission signals can be
repeated up to 5 times (250m) using a conventional TMDS
signal or 7 times (700m) using HDBaseT technology.
What about 3D?
All of our matrix switches and most of our extender products
will pass-through a 3D Blu-ray signal. The 30m and Coax
extender sets do not support frame sequential 3D (Blu-ray),
but will still pass-through interlaced stereo-scopic
3D (Satellite etc.)
How do I control the sources?
Most of our HDMI distribution products support some kind of
IR pass-through from point-to-point extender sets to pro and
HDBaseT matrices. Most of the range now supports
wideband IR meaning it is compatible with any IR device
available on the market. Our Pro and HDBaseT matrix range
(Cat 5e) 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?
Yes. Our HD display adaptors require a 5v power supply at
the TV end to operate. 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. Our new USB power cables overcome the
problem of having a second mains outlet behind the TV.
These useful leads draw the 5v from the USB socket on the
TV to power the receiver, this also means that the receiver
15. FAQs
is only powered when the TV is on making the system more
environmentally friendly.
Do I need to use 1 or 2 cables?
Using our conventional pro (TMDS) transmission method the
Video & Audio is sent along cable #2, IR and HDCP data
is sent along cable #1. Using our HDBaseT technology it’s
possible to send Audio (up to DTS Master), Video (up to 4k),
Ethernet (10/100), and control (RS232 & 2-way IR) down a
single Cat 5e cable.
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 2.25Gbps, which is the equivalent
to a 720p/1080i signal.
• 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 color 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 be 1080i
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 outputting 1080p and
that the TV is Full HD 1080p screen. If this is the case then
the receiver Cat 5e or Coax may need setting up for long
