or other quality duplex multimode fiber optic cable.

Crestron DM-TX-300N/-F DigitalMedia™ CAT & Fiber Transmitters 300N

Multimedia Computer /AV Interface

The DM-TX-300N/-F provides versatile switching between three different video and
audio sources. Inputs on the DM-TX-300N/-F include multi-format analog video,
HDMI, DVI-I, balanced and unbalanced line level audio and SPDIF digital audio.
The HDMI input supports HDMI with HDCP, handling WUXGA computer
resolutions and 1080p60 HDTV with multi-channel lossless audio. The HDMI input
can also handle DisplayPort Multimode signals using an appropriate adapter or
dongle1. The DVI-I input handles DVI as well as analog RGB signals2 up to
WUXGA 1920 x 1200 pixels. The multi-format analog video input accepts
component HDTV signals up to 1080p60 as well as standard definition NTSC/PAL
composite and S-video. Audio inputs include HDMI, stereo balanced line level,
stereo unbalanced RCA and S/PDIF coaxial digital.

A single DM CAT output (DM-TX-300N) or DM fiber output (DM-TX-300N-F) is
provided to feed a centralized DM switcher or to drive a single DM-RMC-100-1 (for
the DM-TX-300N) or DM-RMC-100-F (for the DM-TX-300N-F) Receiver/Room
Controller at the display location (all sold separately). An HDMI output is also
included, which may be set to follow the DM output or to provide a constant
pass-through signal from the DVI-I input to feed a local monitor.

NOTE: The HDMI and DM video/audio outputs function in two modes:

Dual Output is the default mode, where HDMI and DM both output the same signal.
Monitor Output, where the HDMI output will always be sourced from the DVI-I

input and the DM output can be switched to take its source from any of the inputs.
Output mode is selectable from the SIMPL™ Windows program.

For a total custom installation solution, Crestron offers a complete range of
professional AV interface cables and wall plates to complement the
DM-TX-300N/-F.

QuickSwitch HD Technology®

Crestron exclusive QuickSwitch HD technology minimizes the annoying switching
latency that plagues typical digital AV switchers. QuickSwitch HD achieves very
fast switching of digital signals by maintaining a constant HDCP connection with
each device in the system, eliminating the need to re-authenticate each time a
different source is selected.

EDID Format Management

The DM-TX-300N/-F allows for management of the EDID (Extended Display
Identification Data) information that passes between display devices and input
sources in the system. Using Crestron Toolbox™ software, the format and resolution
capabilities of each device can be assessed and managed through the
DM-TX-300N/-F, ensuring reliable operation by instructing sources to output only
the resolutions and formats that can be handled by the displays and system wiring.

NOTE: EDID signal detection and format management in the DM-TX-300N-F
requires connection to a DMC-F or DMC-F-DSP input card (both sold separately).

1. HDMI IN requires an appropriate adapter or interface cable to accommodate a DisplayPort

Multimode signal. HDMI OUT requires an appropriate adapter or interface cable to accommodate a
DVI signal. CBL-DP-HD and CBL-HD-DVI interface cables sold separately.

2. VGA (RGB) to DVI-A adapter included. (DVI-A plug fits in the DVI-I socket.) In addition to RGB,

the DVI-I input can accept component, composite and S-video signals via direct interface to Crestron
MPS Series products (sold separately) or through an appropriate adapter (not included). Input sync
detection is not provided for composite or S-video signal types through the DVI-I connection.

DigitalMedia™ CAT & Fiber Transmitters 300N Crestron DM-TX-300N/-F

Embedded Device Control

The primary objective of every Crestron system is to enable precisely the control
desired for a seamless user experience. The DM-TX-300N/-F includes built-in IR,
RS-232 and Ethernet control ports to allow programmable control of the devices
connected to it. The DM-TX-300N/-F also provides an alternative to conventional
control methods by harnessing the CEC (Consumer Electronics Control) signal
embedded in HDMI. Through its connection to the control system, the
DM-TX-300N/-F provides a gateway for controlling the connected source device
right through the HDMI connection, potentially eliminating the need for any
dedicated control wires or IR probes.

Compact and Versatile

The DM-TX-300N/-F is designed to be placed on a shelf or mounted in an
equipment rack or lectern. It is compact enough to fit inside a presentation lectern or
beneath a table. An array of indicators on the front of the DM-TX-300N/-F provides
for easy setup and troubleshooting, verifying the status of connections and signal
activity at a glance. Advanced configuration is enabled through Crestron Toolbox
software.

A Digital Upgrade for Legacy Systems

The DM-TX-300N/-F also affords a perfect signal converter for integrating
DigitalMedia with analog-based systems like Crestron MPS, QuickMedia® and the
CEN-RGBHV Series (all sold separately). A simple HD15 VGA cable connected
between the output of an MPS system and the DVI-I input of the DM-TX-300N/-F
allows every RGB, component, S-video and composite video input on the MPS to be
converted to DigitalMedia*. Analog audio is converted similarly through a balanced
stereo audio cable. The DM-TX-300N/-F’s HDMI, DVI and S/PDIF inputs may also
be used to expand the input capabilities of the MPS system to handle digital AV
sources.

VGA (RGB) to DVI-A adapter included. (DVI-A plug fits in the DVI-I socket.) In addition to RGB,

*

the DVI-I input can accept component, composite and S-video signals via direct interface to Crestron
MPS Series products (sold separately) or through an appropriate adapter (not included). Input sync
detection is not provided for composite or S-video signal types through the DVI-I connection.

DM-TX-300N-F in a Typical Application

No LAN connection is required for these devices to transmit HDMI in a point-to­point configuration. If you wish to use the control ports (IR, RS-232, Relay, Sense)
from a control system, you can connect either LAN port (the one on the
DM-TX-300N/-F or the DM-RMC-100/-F) to the control system’s network. Both
devices will be connected because Ethernet is embedded inside DM. You may also
use the other LAN connection to provide Ethernet connectivity to a remote device.

Crestron DM-TX-300N/-F DigitalMedia™ CAT & Fiber Transmitters 300N

For DM CAT (e.g. DM-TX-300N) only one power supply is required to power both
DM-TX-300N and DM-RMC-100-1 or other receiver device. The DMNet cable will
carry power from the power supply to the other device. Please use the DMNet Power
Calculator to help calculate how much power is needed for the system
(www.crestron.com/calculators

). For DM fiber (e.g. DM-TX-300N-F), each end has

a local power supply.
