OVERVIEW 

The Extron DTP T HWP 4K 331 D is a single-gang, decorator-style, long distance transmitter for sending HDMI, audio, and bidirectional RS‑232 and IR signals up to 330 feet (100 meters) over a shielded CATx cable to Extron DTP^® 330-enabled products. The one‑gang form factor provides maximum space efficiency in wall mount, floor box, and furniture mount applications. The DTP T HWP 4K 331 D accepts analog stereo audio signals for simultaneous transmission over the same shielded twisted pair cable. It supports video signals at resolutions up to 4K. It also features remote power capability, plus bidirectional RS‑232 and IR pass‑through for remote AV device control. The single‑gang wall‑mountable design of the DTP T HWP 4K 331 D provides the convenience of placing input connections precisely where they are needed.

The HDCP-compliant DTP T HWP 4K 331 D enables the reliable transmission of HDMI signals, supporting Deep Color up to 12-bit, CEC pass‑through, and embedded HD lossless audio formats. In addition, DDC communication of EDID and HDCP is continuously maintained between a source and display, ensuring direct compatibility and optimal signal transmission between devices. The DTP T HWP 4K 331 D also provides a connection for sending stereo analog audio to a DTP 330-enabled matrix switcher, switcher, or signal processor. The analog stereo audio signal is sent over the same shielded twisted pair cable as the HDMI and control signals, eliminating the need for a separate cable run to support analog audio at the DTP 330-enabled product.

The twisted pair transmitter provides other convenient, integrator-friendly features designed to help simplify installation. The DTP T HWP 4K 331 D supports simultaneous transmission of bidirectional RS‑232 and IR signals from a control system for AV device control. Also, the transmitter can be remotely powered over the shielded twisted pair cable by a DTP 330-enabled product, allowing both devices to share one power supply.

The DTP T HWP 4K 331 D can be integrated with an Extron DTP CrossPoint^® Presentation Matrix Switcher, or other DTP 330‑enabled products to support sources at remote locations. The transmitter mounts in an included single-gang decorator-style wallplate that fits a standard US one‑gang size junction box. The wall‑mountable form factor of the DTP T HWP 4K 331 D allows for discreet placement in walls, lecterns, and floor boxes.

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.

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.
