The TL-TP50-HDIR is a cost-effective twisted pair extender set designed for extending HDMI and IR up to 50 meters (164 ft.) over shielded twisted pair cabling (shielded connectors are also required). The system transmits IR from the destination (receiver end) to the source (transmitter end), and requires power on both ends. The transmitter features a built-in loop out, allowing a local display to be connected to the system.
