Multiple Signals Over One Cable — DVIGearís DVI-7520 utilizes HDBaseT™ technology to provide a simple and cost-effective solution for extension of uncompressed HDMI or DVI, embedded audio, bidirectional IR, and RS-232 using a single twisted pair CAT-X cable.

Feature-Rich, Future-Proof — Unlike other products, this extender supports a wide range of HDBaseT features, including: support for 4K/30p (UHD) resolution, bidirectional IR, POH and long-range operation.  It supports extension of HDMI signals with 1080p resolution up to 230 ft. (~ 70 meters) and 4K (UHD) resolution up to 130 ft. (~ 40 meters).

Power Over HDBaseT (POH) — Today there are many HDBaseT products on the market that utilize non-standard implementations of power over the HDBaseT link.  This problem has created numerous interoperability challenges for system integrators who are faced with HDBaseT products that do not work with each other or, in some cases, actually cause equipment failures.  To solve this problem, DVIGearís DVI-7520 includes a fully-compliant implementation of Power over HDBaseT (POH), a key component of the HDBaseT standard. For POH operation, the transmitter unit acts as a PSE device and provides standardized 48 VDC power, as well as a sophisticated handshake feature that prevents power exchange with incompatible devices.  The receiver unit operates as a PD device and accepts POH from the transmitter, thereby eliminating the need for a cumbersome wall mount power supply unit (PSU).  For non-POH operation, the receiver unit can be powered using an optional PSU.

Exceptional Value — The DVI-7520 delivers a powerful combination of advanced features and unmatched performance at a very attractive price point, which makes it a true break-through in value for professional AV system integrators.  This makes it ideally suited for a wide range of digital display applications, including rental & staging events, conference and training rooms, boardrooms, auditoriums, hotels, churches and other demanding environments.
