Kramer Electronics 50-80021090 Hdmi Bidirectional RS232 Ir

Product Description

The KRAMER ELECTRONICS 50-80021090 is an HDMI bidirectional RS232 and IR signal processing accessory designed for AV system integration. It handles HDMI signal transmission alongside two-way RS232 and infrared control passing, allowing a single installation to carry video, audio, and control signals over a common pathway. AV integrators and low-voltage technicians install this unit where centralized control of displays, sources, and peripheral devices is required in a structured AV distribution setup. The combination of HDMI with bidirectional RS232 and IR pass-through reduces wiring complexity and supports clean, manageable rack or wall installations.

This unit is suited for commercial and residential AV installations where HDMI sources need to be extended or distributed while maintaining full RS232 device control and IR remote functionality. Typical scenarios include boardrooms, classrooms, hospitality displays, and home theater systems where a display or projector must be controlled from a remote location alongside the video feed. It is sold as a single unit and is intended for installation by trained AV or low-voltage professionals familiar with HDMI signal routing and control system wiring.
