The Extender is based on the HDBaseT technology. It extends your HD display with the resolutions of 1080p/60Hz up to 330 feet (100 meters) away from your HDMI or DVI-D source using one CAT5e/6 cable. It also extends Ethernet and provides an IR back channel to control AV sources using the same CAT5e/6 cable. The three Ethernet ports on both the Sender and Receiver are connected to standard network devices such as 100Base-T routers and hubs. Built-in IR extender function allows remote control of Source devices from remote viewing location by sending IR commands received in the vicinity of the Display back to the Source devices.
