DigitalMedia Fiber Transmitter 300N

The DM-TX-300N-F is a DM® 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, the DM-TX-300N-F connects to the head end or display location using multimode fiber optic cable. It provides HDMI®, DVI, VGA, S/PDIF, and analog video and audio inputs, plus Ethernet, RS-232, and IR control ports for a total connectivity solution.

Installed in a stationary podium or equipment rack, the DM-TX-300N-F 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 Fiber connection (MP-WP186) at each location.
