DM-TX-401-S

The DM-TX-401-S is a DM 8G® Fiber transmitter and switcher that offers a versatile interface for computers and high-definition AV sources as part of a complete Crestron® DigitalMedia™ system. Compact and rack-mountable^[1], the DM-TX-401-S connects to the head end or display location through a single multimode fiber strand. It provides DisplayPort, HDMI®, VGA, and analog video and audio inputs, plus Ethernet, RS-232, and IR control ports, and a USB HID host port for a total connectivity solution.

Installed in a stationary podium or equipment rack, the DM-TX-401-S provides an ideal solution for integrating rack-mounted sources, switchers, and AV receivers into the DigitalMedia system. Mounted in a movable lectern or AV cart, or just as a portable device, it affords a simple means for connecting laptops, cameras, and other portable sources at any number of wall plates and floor boxes throughout a conference center or auditorium, requiring just a single DM 8G Fiber connection (MP-WP187-S or MPI-WP187-S) at each location.

DigitalMedia 8G™ Fiber
As the leader in HDMI and control system technologies, Crestron developed DigitalMedia (DM®) to deliver the first complete HD AV distribution system to take HDMI to a higher level. DigitalMedia allows virtually any mix of HDMI and other AV sources to be distributed throughout a home, office, school, or virtually any other facility.

DigitalMedia 8G is the latest generation of DM, providing a true one-wire transport for moving high-definition video, audio, and Ethernet over fiber optic cable without any compression or repeaters. Engineered for ultra high-bandwidth and ultimate scalability, DM 8G handles uncompressed video beyond high-definition with support for HDCP, Deep Color, and 3D. Audio capabilities include support for high-bitrate 7.1 audio formats like Dolby® TrueHD and DTS-HD Master Audio™ as well as uncompressed linear PCM. All signals are transported over one strand of multimode fiber, supporting distances up to 1000 feet (300 m) using CresFiber® 8G Fiber Optic Cable.^[2]

Multimedia Computer/AV Interface
The DM-TX-401-S provides simple switching among four inputs. Inputs can be selected manually from the front panel, through a Crestron control system, or automatically. Inputs include:

• DisplayPort — Accommodates Apple® laptops and other computers with this type of interface.
• HDMI — Supports HD 1080p60 video and WUXGA computer signals with HDCP, Deep Color, 3D, and multi-channel HD lossless audio. Also handles DVI signals using an appropriate adapter or interface cable^[3].
• PC — This VGA type input handles analog RGB signals up to WUXGA 1920x1200 pixels, as well as component video up to 1080p60^[4]. A 1/8" (3.5mm) stereo audio input is included to accommodate analog audio signals from an unbalanced line-level source or headphone output.
• Video — Accepts the connection of an NTSC or PAL composite video source with stereo unbalanced line-level audio.

Note: Audio breakaway capability enables either analog audio input to be used with any video input.

A single fiber strand connects the DM-TX-401-S to a DM switcher or receiver, transporting video, audio, control, and networking signals all through one simple SC type optical connection.^[2] Used with a single DM 8G Fiber Receiver/Room Controller and optional Crestron Control System, the DM-TX-401-S affords a simple solution for extending a multimedia computer or AV signal to a single display up to 1000 feet (300 m) away^[2]. As part of a larger system using a DM-MD series switcher, multiple DM-TX-401-Ss may be deployed to enable the distribution of several sources at different locations to feed multiple displays throughout any room or larger facility.

Advanced Analog Video Processing
Via the PC and Video inputs, the DM-TX-401-S employs advanced analog video processing with anti-aliasing and 3D comb filtering to ensure the reliable distribution of analog VGA and video sources. Built-in time base correction is also included to ensure optimal results for use with video tape players.

LAN Connectivity
Along with high-definition AV and control, DigitalMedia also integrates high-speed Ethernet networking for a total signal distribution solution. The DM-TX-401-S includes a 10/100 Ethernet port, providing a convenient LAN connection for a local network device.

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-401-S includes built-in IR, RS-232, and Ethernet control ports to allow programmable control of the devices connected to it. But, it can also provide an alternative to such conventional control methods by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its connection to the control system, the DM-TX-401-S 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 emitters.

Keyboard/Mouse Extender
The DM-TX-401-S functions as a keyboard/mouse extender, allowing a USB HID-compliant keyboard and/or mouse to be connected to the front panel and used to control a computer or other component located at the central equipment rack or some other location.

EDID Format Management
The DM-TX-401-S 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-401-S, ensuring reliable operation by instructing sources to output only the resolutions and formats that can be handled by the displays and system wiring.
