SmartAVI HDBaseT Dual DVI-D + USB + RS232 + Audio Extender

Experience true long-range multimedia extension with the SmartAVI SDX-2P HDBaseT Dual DVI-D + USB + RS232 + Audio Extender. Harnessing HDBaseT technology, it can transport dual DVI-D video signals along with USB peripherals, RS232 control, and audio over two standard CAT5e/6 cables up to 400 feet (approximately 122 meters). This design eliminates the need for costly shielded cables while delivering crisp, high-definition video to multiple displays in conference rooms, classrooms, retail environments, and digital signage networks. The SDX-2P is built for reliability and ease of installation, offering a scalable solution for modern AV setups that demand flexibility, centralized control, and high-quality video across sizable spaces.

• Long-range HDBaseT extension: Transmit two DVI-D video streams, plus USB, RS232, and audio, up to 400 feet away using standard CAT5e/6 cables—no expensive shielded cabling required. The HDBaseT protocol provides robust signal integrity, simplified routing through walls or racks, and better resistance to interference compared with older DVI extenders. This makes it ideal for boardrooms, auditoriums, and digital signage where distance matters.
• Dual DVI-D video support: Send two high-definition DVI-D signals from a single transmitter to a pair of displays, enabling mirrored content or independent streams for multi-monitor presentations. Whether you’re delivering a single presentation across two screens or displaying complementary content on each display, the SDX-2P keeps visuals sharp and synchronized.
• Comprehensive multimedia pass-through: USB, RS232, and audio passthrough are supported along with the DVI-D video signals, allowing you to connect keyboards, mice, control devices, speakers, or other peripherals without compromising signal quality. This functionality is especially useful for interactive kiosks, lecture halls, and control rooms where centralized management and multimedia integration are critical.
• Plug-and-play installation: Designed for straightforward deployment by IT staff, installers, or power users, the extender pairs quickly with minimal configuration. Its user-friendly setup reduces downtime during room conversions, renovations, or new deployments, enabling fast, reliable setup for regular AV schedules or spontaneous events.
• Flexible CAT5e/6 cabling: Leverage common, affordable Ethernet cabling to achieve dependable performance while maintaining easy routing behind furniture, in ceiling spaces, or within rack enclosures. The SDX-2P provides a practical blend of cost efficiency and performance for growing multi-display or multi-room installations.
