Omega 4K/UHD Scaler for HDBaseT and HDMI
AT-OME-RX31
The Atlona AT-OME-RX31 is an HDBaseT receiver, three-input switcher, and 4K/UHD scaler
with a local HDMI input. Part of the Omega™ Series of integration products for modern AV
communications and collaboration, the OME-RX31 features two HDBaseT inputs for receiving
video up to 4K/60 4:2:0, plus embedded audio, control, Ethernet, and USB over distances up
to 330 feet (100 meters). The HDMI input supports video up to UHD/60 4:4:4. The OME-RX31 is
HDCP 2.2 compliant and features 4K/60 upscaling and downscaling with frame rate conversion.
Additionally, it provides integrated control for displays and room functions such as motorized
screens, and can be externally triggered with the addition of an occupancy sensor. The OME-
RX31 is ideal for 4K presentation applications with Omega, HDVS-200, or UHD-EX Series
transmitters, as well as Atlona AV presentation switchers with HDBaseT outputs, local HDMI
sources, and the Gain™ Series ampliers.

1. Make sure the AT-OME-RX31 is powered
2. Press and hold the IP MODE button, on the rear of the unit, for approximately ve seconds.
The AT-OME-RX31 is shipped with DHCP enabled. Once connected to a network, the DHCP
server (if available), will automatically assign an IP address to the unit. If the AT-OME-RX31
is unable to detect a DHCP server within 15 seconds, then the unit will use a self-assigned IP
address within the range of 169.254.xxx.xxx.
Use an IP scanner, along with the MAC address on the bottom of the unit, to identify the unit on
the network. If a static IP address is desired, the unit can be switched to static IP mode.
The default static IP address is 192.168.1.254.
