DM-TX-300N-F

The DM-TX-300N-F is a DM® Fiber transmitter and switcher that features a full complement of high-definition digital and analog AV inputs. It provides a remarkably simple, yet versatile interface for connecting nearly any computer or AV source to a Crestron® DigitalMedia system. Boasting HDMI®, DVI, RGB, and multi-format analog video inputs, plus digital and analog audio inputs, the DM-TX-300N-F is ideal for use at a lectern, conference table, equipment cabinet, or wall plate input to send signals to a display or switcher many feet away.

DigitalMedia™
As the leader in HDMI and control system technologies, Crestron has developed DigitalMedia, the first complete HD AV distribution system that takes HDMI to a higher level, and allows virtually any mix of AV sources to be distributed throughout the home, office, school, or virtually any other facility.

DigitalMedia distributes uncompressed digital video and audio signals up to 1000 feet (300 m) using multimode fiber optic cable^[1]. DigitalMedia thoughtfully manages all of the different signals and devices, matching each source's output to the capabilities of the selected display(s) without using scaling or compression. Every signal is preserved in its native video resolution and audio format, ensuring a pure, lossless signal path throughout.

Multimedia Computer/AV Interface
The DM-TX-300N 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 dongle^[2]. The DVI-I input handles DVI as well as analog RGB signals^[3] up to WUXGA 1920x1200 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 SPDIF coaxial digital.

A single DM Fiber output is provided to feed a centralized DM switcher, or to drive a single DM-RMC-100-F Receiver/Room Controller at the display location. 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.

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 the 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.

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. 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^[3]. Analog audio is converted similarly through a balanced stereo audio cable. The DM-TX-300N-F's HDMI, DVI, and SPDIF inputs may also be used to expand the input capabilities of the MPS system to handle digital AV sources.
