The Extron FOXBOX Rx HDMI HDMI Fiber Optic Extender is a receiver for long haul transmission of HDCP-compliant HDMI, audio, and RS-232 control signals over fiber optic cabling. Engineered for reliability and exceptional high resolution image performance, it uses Extron all-digital technology to deliver perfect pixel-for-pixel HDMI computer-video images up to WUXGA 1920x1200 resolution, including HDTV 1080p/60. Designed specifically for AV systems, the FOXBOX Rx HDMI includes many integrator-friendly features such as Key Minder^®, Auto Input Memory, internal test patterns, and real-time system monitoring. A compact, low profile enclosure allows for discreet installation behind a flat-panel display.

The FOXBOX Rx HDMI is part of the extensive FOX Series of fiber optic products from Extron and is compatible with FOX Series HDMI, DVI Plus, DVI, VGA, and VGA/YUV transmitters. The FOXBOX Rx HDMI can be used for simple point-to-point applications or in combination with FOX Series switchers and matrix switchers for support of wider installations.

The FOXBOX Rx HDMI is ideal for a wide range of applications requiring long distance acceptance of high resolution content with the highest quality. Because transmission of content is inherently secure and immune to outside interference, fiber applications are favored in government, military, and medical environments. The FOXBOX Rx HDMI receiver features industry standard LC-type connectivity.

The receiver features Key Minder to enhance and simplify integration of HDMI-equipped devices. For HDMI signals with protected content, Key Minder authenticates and maintains continuous HDCP encryption to support quick and reliable transmission across a fiber optic infrastructure. If HDCP-encrypted content is transmitted to a non-compliant display, the receiver sends a full-screen green signal, providing immediate visual notification that the protected content cannot be viewed on the display.

The FOXBOX Rx HDMI MM supports multimode fiber at 850 nm, which is typically used within buildings or facilities with moderate-range transmission distances. The FOXBOX Rx HDMI SM supports singlemode as well as multimode fiber at 1310 nm. Singlemode fiber offers long-range transmission capability over extreme distances of up to 30 km (18.75 miles). It is used in very large facilities such as airports and stadiums, as well as connecting over very long distances between facilities such as university campuses.

Analog RGB/HD Component-to-HDMI Conversion

The FOXBOX Rx HDMI is ideal for AV systems that include a variety of analog and digital displays and sources. Pairing the FOXBOX Rx HDMI with a FOX Series VGA or VGA/YUV transmitter provides easy conversion of analog RGB/HD component to HDMI for non-HDCP content.

Features

Accepts fiber optic signals from FOX Series transmitters and provides HDMI video, stereo audio, and RS-232 control signals — Accepts signals from Extron FOX Series HDMI, DVI Plus, DVI, VGA, and VGA/YUV transmitters for integration flexibility.

Outputs: HDMI connector, unbalanced or balanced stereo audio on captive screw connector

HDCP compliant

All-digital technology provides pixel-for-pixel performance with signals up to 1920x1200, including HDTV 1080p/60 — The FOXBOX Rx HDMI provides pixel-for-pixel display of video signals for optimal image quality at resolutions up to 1920x1200.

Key Minder^® continuously verifies HDCP compliance for quick, reliable switching — Key Minder authenticates and maintains continuous HDCP encryption between input and output devices to ensure quick and reliable switching in professional AV environments, while enabling simultaneous distribution of a single source to multiple displays.

HDCP Visual Confirmation — When HDCP‑encrypted content is transmitted to a non‑HDCP compliant display, a full‑screen green signal is sent to the display for immediate visual confirmation that protected content cannot be viewed on that display.

HDMI audio de-embedding with analog stereo outputs — Digital HDMI audio is made available as a balanced or unbalanced analog stereo signal on captive screw connectors.

Selectable HDMI audio pass-through — A rear panel toggle switch enables or disables audio signal pass-through on the HDMI output.

Audio muting capability

Available as an 850 nm multimode model for moderate-range transmissions up to 2 km (1.25 miles) and a 1310 nm singlemode model for extreme distances up to 30 km (18.75 miles)

Industry standard LC connectors provide reliable physical connectivity and precise fiber core alignment

Alarm notification for fiber link loss — The FOXBOX Rx HDMI receiver can be set up to trigger an external control system for immediate notification when a fiber link has been lost.

Auto Input Memory — When activated, the FOXBOX Rx HDMI automatically stores position and detail settings based on the incoming signal. When that signal is detected again, the proper image settings are automatically recalled from memory.

30 user memory presets — In addition to Auto Memory, 30 user memory presets on the receiver are available for saving and recall of position and detail information for multiple incoming sources. The ability to save and recall presets is useful in switcher-based environments.

RS-232 control — The FOXBOX Rx HDMI receiver features RS-232 serial ports for control and configuration.

Real-time status LED indicators for troubleshooting and monitoring — Front and rear panel LEDs verify signal presence, HDCP authentication, link status, and power.

Internal test patterns for calibration and setup — Three test patterns are available, including grayscale, color bars, and alternating pixels.
