MAINTENANCE
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 receiver’s
capabilities, then the signal can be boosted by way of an
AMP-001-010 as an in-line repeater up to 7 times (490m)
using HDBaseT technology.
What about 3D?
The RX-70-4K, all of our matrix switches and most of our
extender products will pass-through a 3D Blu-ray signal
(frame packing - Blu-Ray & Stereoscopic - satellite/cable).
How do I control the sources?
All of our HDMI distribution products support IR pass-
through from point-to-point extender sets to AMP and
HDBaseT matrices. Most of the range now supports
wideband IR meaning it is compatible with any IR device
available on the market.
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-70-4K 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 12v. 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.
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 and 4K
resolutions at 30Hz, 4:2:2 colour. 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 1080p but not 4K at a TV location
Firstly ensure that both the source is capable of outputting
4K and that the TV is a UHD screen. If this is the case
then the display receiver or PP-POH 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.
Clean this unit with a soft, dry cloth only. Never use
alcohol, paint thinner or other harsh chemicals.
