DigitalMedia 8G™ Single-Mode Fiber Transmitter 401

The DM-TX-401-S2 provides a versatile interface for computers and high-definition AV sources as part of a complete Crestron® DigitalMedia™ system. It functions as a DM 8G® SM Fiber transmitter and switcher, providing DisplayPort, HDMI®, VGA, composite video, and analog audio inputs. It also functions as a control module, providing RS-232 and IR control ports, plus Ethernet and USB HID ports for a total connectivity solution. It can be rack-mounted, placed on a shelf, or attached under a table [1], and connects to the head end or display location using one single-mode fiber strand.
Installed in a stationary podium or equipment rack, the DM-TX-401-S2 offers an ideal solution for integrating rack-mounted sources, switchers, and AV receivers into the DigitalMedia system. Mountedunder a table or in a movable lectern or AV cart, it affords a simple means for connecting mobile devices, computers, cameras, and other “BYOD” sources. In a conference center or auditorium, a portable DM-TX-401-S2 can be connected to the system through wall plates and floor boxesas needed, requiring just a single LC optical fiber connection at each location.
DigitalMedia 8G™ Single-Mode 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. The latest generation of DMis called DigitalMedia 8G (DM 8G). Engineered for ultra high-bandwidth and ultimate scalability, DM 8G provides a true one-wire lossless transportfor moving high-definition video, audio, Ethernet, and control signals over a choice of twistedpair or fiber optic cable.
DM 8G SM Fiber uses single-mode fiber to enable long-distance signal distribution across a campus, complex, or municipality. DM 8G SM Fiber handles uncompressed Full HD 1080p video signalswith support for 3D, Deep Color, and HDCP, as well as computer signals up to WUXGA. 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 single-mode fiber, supporting distances up to 7.5 miles (12 km) using CresFiber® 8G SM or G.652.D single-mode fiber optic cable.
Multimedia Computer/AV Interface
The DM-TX-401-S2 provides simple switching amongfour inputs. Inputs can be selected manually from the front panel, programmatically through a Crestron control system, or automatically by simply connecting a source to one of the inputs. Inputs include:

• DisplayPort — Accommodates Apple® laptops and other computers with this type of interface.
• HDMI — Provides a digital multimedia input for mobile devices, computers, and AV sources with resolutions up to HD 1080p60 and WUXGA. Also handles DVI signals using an appropriate adapter or interface cable.
• PC — ThisVGA type input handles analog RGB signals up to WUXGA 1920x1200 pixels, as well as component video up to 1080p60[5].A 1/8” (3.5mm) stereo audio input is included to accommodate the analog audio signal from an unbalanced line-level source or headphone output.
• Video — Accepts the connection of an NTSC or PAL composite video sourcewith stereo unbalanced line-level audio.
