The Gefen DVI KVM HDBaseT 2.0 Extender is a sender and receiver kit that uses Gefen's implementation of the HDBaseT 2.0 specification to extend DVI, audio, and control signals up to 495' over a Cat 5e cable. It supports 2-way audio and DVI signals with resolutions up to 1080p and 1920 x 1200 as well as 4096 x 2160 at 30 Hz 4:4:4 and 3840 x 2160 up to 60 Hz 4:2:0. 

The extender supports HDCP 2.2 and HDCP 1.4 protocols so it can work with HDCP compliant equipment. USB and RS-232 support allows equipment control as well as mouse and keyboard over the the Cat 5e cable run. The PoH (Power over HDBaseT) capability allows you to supply power to the receiver and to the sender over the Cat 5e cable run, sparing you the need of a power supply on the sender unit. The HDBaseT 2.0 Colligo platform provides additional features such as USB and two-way audio extension and ensures an even more robust and resilient connection than the industry-standard HDBaseT. 

Supported HBR formats include Dolby Atmos, Dolby TrueHD, DTS:X, and DTS-HD Master Audio. USB, RS-232, and two-way L/R analog audio can be extended between the sender and the receiver to accommodate a complete workstation including keyboard, mouse, select USB peripherals, microphone, headphones, and powered speakers.

The Gefen Syner-G software, with its powerful EDID management capabilities, speeds up configuration, performs real-time performance audits via Link Monitoring, and simplifies in-field firmware updates.

Sender and receiver pair extends DVI, USB, RS-232, and two-way audio over a single Cat 5e up to 495'.
Supports resolutions up to 4K DCI-Cinema (4096 x 2160 at 30 Hz 4:4:4) and 4K Ultra HD (3840 x 2160 at 60 Hz 4:2:0).
Supports 2-way stereo analog audio as well as 7.1 channels of LPCM and HBR (High Bit Rate) lossless digital audio when embedded in HDMI signal using optional Gefen DVI to HDMI cables.
Supports USB and RS-232 extension between the sender and the receiver units, facilitating keyboard, mouse, and peripherals functionality for extended workstations and the control of A/V sources placed near the sender unit and sending automation commands to the display or another device placed near the receiver unit.
PoH (Power over HDBaseT) technology provides power from the receiver to the sender unit, using the same Cat 5e cable that extends the DVI, audio, and control signals. Only the receiver unit needs an external power supply. The PoH standard ensures compatibility with other PoH class-compliant devices.
