1. INTRODUCTION
Transmitter
This Transmitter is an HDMI/VGA switch with audio embedding and
HDBaseT output. The wall plate is designed for use with UK two-
gang sized enclosures. This Transmitter can send high denition
uncompressed audio/video along with Ethernet over a single cable
up to a distance of 100 meters at 1080p@60Hz.
The HDMI input supports resolutions up to 4K@60Hz (4:4:4, 8-bit). The
VGA input supports resolutions up to WUXGA (RB) and with the use of
the associated 3.5mm audio input, stereo audio may be embedded
as well. To provide maximum compatibility with a wide range of
display types, all sources will be automatically scaled to match the
preferred resolution and timing of the connected display (as reported
by the display's EDID). Despite HDBaseT’s 10.2Gbps bandwidth
limitation, even 4K UHD HDMI video sources, up to and including
4K@60Hz (4:4:4, 8-bit), can be supported by converting the signal to
4K@30Hz when necessary.
This unit also supports automatic input selection between the HDMI
and VGA inputs, with hot plug detection, enabling hands-free
operation. Additionally, the unit may be powered locally or via 48V
PoH (Power over HDBaseT) from a compatible HDBaseT Receiver,
which allows for greater exibility in installations.
Receiver
This receiver is a great solution for extending uncompressed HD
audio and video as well as Ethernet and control via a single run of
Cat.5e/6/7 cable over distances of up to 100 meters. Multiple data
and control interfaces are provided, including Ethernet, IR and RS-232
connections. This Receiver complies with the advanced HDCP 2.2 and
HDMI 2.0 standards, as well as supporting the legacy HDCP 1.x and
HDMI 1.x standards. This Receiver (PSE) can provide 48V PoH (Power
over HDBaseT) to compatible Transmitters allowing for greater exibility
within different installation scenarios.
