The Crestron® HD-MD-300-C-E delivers an incredibly simple and cost­effective multimedia presentation solution for classrooms and meeting
spaces. It allows a laptop or mobile device (HDMI® or VGA) to be connected
at a wall plate, and routes the signal to a display or projector up to 230 feet
(70 meters) away. An additional HDMI source can be connected at the display
device location (or through an optional wall plate near the display). Fully
automatic operation detects when a source is connected or disconnected
at any input and turns the display on and off, alleviating the need for any
control panels or remotes. Built-in scaling ensures an optimal video image
for SD and HD video signals, as well as for high-res computer signals.

port on the receiver allows for connection to an Ethernet network to enable
easy setup and configuration via a web browser. Advanced functionality is
enabled through integration with a Crestron control system.

Convenience LAN Jack

The wall plate transmitter includes a CAT6a RJ45 courtesy jack, which can
be used to provide a 1000Base-T network connection for computers and
other devices. The front panel jack simply passes through to a parallel jack
on the rear, which connects to an available port on the customer’s LAN.
This LAN jack is provided as a convenience to supplant the need for a
separate RJ45 wall jack.

Note: This LAN jack is completely independent of the LAN port on the
receiver and cannot be used to extend Ethernet signals or interface the
HD-MD-300-C-E with a computer, control system, or any other equipment.

Multimedia Computer/AV Auto-Switcher

The HD-MD-300-C-E handles high-definition video and computer sources
with resolutions up to Full HD 1080p60, 1080i30, or WUXGA 1920x1200.
One HDMI input, one VGA input, and one analog audio input are provided
on the transmitter to support the connection of computers, mobile devices,
and other media sources. An additional HDMI input is provided on the
receiver, which may be wired to an optional wall plate or used to connect
a local source such as a mini PC or Crestron AirMedia® wireless
presentation system.

Faceplate

not included

Composed of a compact transmitter and receiver pair (models HD-TX-201-

C-2G-E and HD-RX-201-C-E respectively), the HD-MD-300-C-E installs in

minutes and requires no special programming. The transmitter mounts in
a standard 2-gang US electrical box, while the receiver mounts behind the
display or above the projector. The only connection required between the
transmitter and receiver is a single CAT type twisted pair cable.

The inputs on both components can be configured to switch automatically
or be controlled through a Crestron control system. Auto-detection on each
input enables plug-and-play simplicity, supporting HDMI, DVI, or Dual-Mode
DisplayPort signals via any HDMI input, and VGA, RGB, or component video
signals via the VGA input.

HD Signal Extender

A single CAT type cable (sold separately) links the HD-MD-300-C-E
transmitter and receiver together. This cable can be up to 230 feet
(70 meters) in length, offering an ideal point-to-point signal extender
solution for virtually any room with a single display device.

HD Scaler

One might assume that any modern display device should support whatever
sources you connect to it. In fact, many displays just can’t handle all the
different formats and resolutions you’re likely to encounter day-to-day in
a dynamic presentation environment. With its built-in professional scaler,
the HD-MD-300-C-E enables support for a complete range of digital and
analog signals, ensuring that every source displays reliably and beautifully.
Automatic calibration is achieved using the display’s EDID

— just connect
the receiver to the display and it intelligently converts and enhances the
signal for optimal appearance on the display screen.

EDID Format Management

To ensure that every source gets displayed at its optimal resolution and
format, the HD-MD-300-C-E provides comprehensive management of
the EDID information that passes between the display, scaler, and source
devices. Most applications require no changes to the default settings. For
applications requiring custom configuration, the HD-MD-300-C-E allows
for easy assessment of each device’s format and resolution capabilities,
with the ability to configure signals appropriately for the most desirable
and predictable behavior.

Control System Integration

Fully programmable functionality can be enabled through integration with
a Crestron control system. Integration with a control system also enables
centralized monitoring using the Crestron Fusion® Enterprise
Management Service.

Low-Profile Installation

The wall plate transmitter (HD-TX-201-C-2G-E) is designed to mount in
a 2-gang US electrical box, while the receiver (HD-RX-201-C-E) typically
mounts on the wall behind a flat-panel display or on the ceiling above a
projector. Alternately, the receiver can be attached to a single rack rail in
the back of an equipment cabinet. Both components are powered together
using a single wall mount power pack (included) connected at the receiver
location. Power is carried between the receiver and transmitter over the
DM Lite link connection.

QuickSwitch HD™ Technology

Handling digital media signals means handling HDCP (High-bandwidth
Digital Content Protection), the encryption scheme used by content
providers to protect their DVDs, Blu-ray™ discs, and broadcast signals
against unauthorized copying. Viewing HDCP encrypted content requires a
source device to “authenticate” each display and signal processor in the
system and issue it a “key” before delivering an output signal. Crestron
QuickSwitch HD manages these keys to ensure fast, reliable switching and
immunity to “blackouts.”

Audio De-Embedding

Its analog audio output allows the HD-MD-300-C-E to extract the stereo
audio signal from digital sources to feed a sound bar, amplified speakers,
or a separate sound system.

[6]

Embedded Device Control

To deliver fully automatic operation of the complete system, the HD-MD­300-C-E can turn the display device on and off via its HDMI connection
using CEC (Consumer Electronics Control) commands, or via the built-in
IR or RS-232 port. For advanced applications using a Crestron control
system, all of the HDMI, IR, and RS-232 ports on the HD-MD-300-C-E can
be utilized to attain fully-programmable control of the display, sources, and
other devices in the room.
