The DTP T USW 333 provides reliable switching and long distance transmission of HDMI and analog video signals. For simplified operation, the DTP T USW 333 can automatically switch between the digital and analog sources. Stereo analog audio can be embedded onto the digital video output signal for transport over DTP. To suit the needs of the application, there is also the option to send analog audio alongside the video and control signals over the shielded twisted pair cable to a DTP 330-enabled matrix switcher, switcher, or signal processor. In addition, the analog audio input can be assigned to any of the three video inputs, or it can be set to follow the input switch.

To enhance and simplify integration of sources and displays, and to help ensure optimal system performance, the DTP T USW 333 features EDID Minder. EDID Minder is an Extron‑exclusive technology that manages EDID communication between the display device and input sources to ensure that the correct video formats are displayed reliably.

The switcher supports simultaneous transmission of bidirectional RS‑232 and IR signals from a control system, providing remote control to source equipment or remote displays. For added installation flexibility, the DTP T USW 333 transmitter can be remotely powered over the shielded twisted pair cable by a DTP 330‑enabled product. This simplifies installation and allows both devices to share one power supply. The DTP T USW 333 can be integrated with an Extron DTP CrossPoint^® Presentation Matrix Switcher, or other DTP 330‑enabled products to support sources at remote locations.

The DTP output can be configured for compatibility with HDBaseT-enabled displays to send digital video and embedded audio, plus bidirectional RS-232 and IR signals up to 330 feet (100 meters) over a shielded CATx cable.

The DTP T USW 333 offers convenient control options, including front panel control, RS‑232, and contact closure with tally output. The switcher is housed in a 1" (2.5 cm) high, half rack width metal enclosure that allows for discreet placement in lecterns or beneath tables.

Extron recommends Extron-certified XTP DTP 24 shielded twisted pair cable, shielded RJ-45 plugs, jacks, and couplers engineered for optimum signal transmission with Extron DTP Series products. The XTP DTP 24 cable is certified to 475 MHz and utilizes a SF/UTP design with four unshielded 24 AWG twisted pair conductors inside an overall braid and foil shield for superior performance and noise immunity.
