TP−789Rxr是一款高性能，扩展范围广的HDBaseT接收器，用于4K@60Hz (4:2:0) HDMI、以太网、RS−232和IR信号以及双绞线双向供电。它通过Kramer铜缆以高达 4K@60Hz (4:2:0) 24bpp的视频分辨率将视频信号扩展到长达100米（330英尺），并为更低的高清视频分辨率提供了更大的覆盖范围。此接收器可自动感应并通过铜缆扩展电缆向POE（以太网供电）接收器设备（例如PoE墙面板）供电，或者通过扩展电缆从PoE供应器远程设备接受PoE。

• High Performance Standard Extender — Professional HDBaseT extender for providing extended–reach signals and powering over twisted–pair copper infrastructures. TP–789Rxr is a standard extender that can be connected to any market–available HDBaseT–compliant extension product. For optimum extension reach and performance, use recommended Kramer cables.
• Bidirectional PoE (Power over Ethernet) — Auto–senses the extension line PoE status and either provides power to a remote POE acceptor such as a PoE wall–plate, or accepts power from a remote PoE provider such as a PoE matrix.
• HDMI Signal Extension — Supports deep color, x.v.Color™, lip sync, HDMI uncompressed audio channels, Dolby TrueHD, DTS–HD, 2K, 4K, and 3D as specified in HDMI 2.0. EDID and CEC signals are passed through from the source to the display.
• I–EDIDPro™ Kramer Intelligent EDID Processing™ — Intelligent EDID pass–through algorithm that ensures Plug and Play operation for HDMI source and display systems.
• Multi–channel Audio Extension — Up to 32 channels of digital stereo uncompressed signals for supporting studio–grade surround sound.
• Ethernet Extension — Ethernet interface data flows in both directions, allowing extension of up to 100Mbps Ethernet connectivity for LAN communication and device control.
• Bidirectional RS–232 Extension — Serial interface data flows in both directions, allowing data transmission and device control.
• Bidirectional Infrared Extension — IR interface data flows in both directions, allowing remote control of peripheral devices located at either end of the extended line.
• Cost–Effective Maintenance — Status LED indicators for HDMI and HDBT ports and PoE feed status facilitate easy local maintenance and troubleshooting. Local firmware upgrade via RS–232 connection ensures lasting, field–proven deployment.
• Easy Installation — Single cable connectivity for both HDBaseT signals and power. Compact DigiTOOLS® fan–less enclosure for dropped–ceiling mounting, or side–by–side mounting of 3 units in a 1U rack space with the recommended rack adapter.
