Atlona AT-100CER-PoE-EXT Description

The Atlona 100CER-PoE-EXT is an HDBaseT transmitter and receiver combination that includes the AT-UHD-EX-100CE-TX-PD HDBaseT transmitter and AT-UHD-EX-100CE-RX-PSE HDBaseT receiver. It extends HDMI up to 330 feet (100 meters) over category cable with Ethernet pass-through and RS-232 control. The 100CER-PoE-EXT supports video signals up to 4K/UHD @ 60 Hz with 4:2:0 chroma subsampling, plus embedded multi-channel audio.

The transmitter is remotely powered by the receiver via Power over Ethernet. This makes the 100CER-PoE-EXT ideal for applications in which the transmitter needs to be installed in a location where local AC power may not be available, such as a lectern or conference room table.

The 100CER-PoE-EXT is similar to the AT-UHD-EX-100CE-KIT extender, but is designed for applications in which the transmitter needs to be remotely powered by the receiver. The table below provides a summary of the key differences between the two extenders.
