The Altona AT-UHD-EX-70C-RX is an HDBaseT receiver for AV signals up to 230 feet (70 meters) over category cable with RS-232 and IR control plus Power over Ethernet capability. It is compatible with video signals up to 4K/UHD 60Hz with embedded multi-channel audio and remote 48V Power over Ethernet. The AT-UHD-EX-70C-RX is HDCP 2.2 compliant and supports EDID communication. The receiver features a quarter rack width metal enclosure for easy installation with rear panel I/O ports for uncluttered wire management. Use with an optional AT-IR-CS-RX IR receiver cable to capture IR remote commands for AV system control.

This receiver is used in commercial and applications that call for an HDBaseT receiver with a compact form factor that allows for simple mounting behind displays and at projectors. These applications will not require an AC outlet for the receiver; since the receiver is powered by an Altona switching product. This receiver will also be used to simplify control of the AV system by working with 12 volt-based IR receivers as well as passing through RS-232 commands.
