Get to know this product.

The Atlona AT-UHD-EX-100CE-TX-PD is an HDBaseT transmitter for HDMI transmission up to 330 feet (100 meters) over category cable with Ethernet pass-through and RS-232 control. It transmits video signals up to 4K/UHD @ 60 Hz with 4:2:0 chroma subsampling, plus embedded multi-channel audio. The AT-UHD-EX-100CE-TX-PD is HDCP 2.2 compliant and supports EDID communication. The transmitter features a quarter rack width metal enclosure for easy rack mounting with rear panel I/O ports for uncluttered wire management. This device is externally powered via Power over Ethernet, and is ideal for use with Atlona switchers with PoE-equipped HDBaseT inputs, including the AT-UHD-CLSO-612ED, AT-UHD-CLSO-840, and AT-UHD-SW-5000ED.

The AT-UHD-EX-100CE-TX-PD transmitter simplifies system design when powered by an Atlona switcher with HDBaseT inputs, reducing cost and complexity by eliminating the need for a power supply. It can also be paired with the AT-UHD-EX-100CE-RX-PSE receiver and AT-HDVS-200-RX scaling receiver, both delivering PoE. Installer-friendly features include a rack-mountable form factor that allows four transmitters to share a single 1U rack tray, and a front mounted USB port for easy firmware updates.

This transmitter is ideal for use in applications where:

  • HDBaseT transmitters need to be installed in a location where local AC power may not be available, such as a lectern or conference room table
  • 4K/UHD signal extension and HDCP 2.2 compliance are necessary in the system design

Product Compatibility

The AT-UHD-EX-100CE-TX-PD is compatible with the AT-UHD-EX-100CE-RX-PSE receiver, and both products are available together as a kit. This transmitter is also ideal for Atlona switchers and matrix switchers with HDBaseT inputs. See below for a list of compatible products. This HDBaseT transmitter is also ideal for use with the AT-OME-RX11 receiver with audio de-embedding, as well as the AT-OME-RX21 scaling receiver with local HDMI input and audio de-embedding.
