5x2 HDMI Matrix Switcher with Mirrored Outputs
AT-HDR-SW-52ED
The Atlona AT-HDR-SW-52ED is a 5×2 HDMI matrix switcher for high dynamic range (HDR)
formats. Part of the comprehensive family of Atlona 4K HDR integration products, it features
ve HDMI inputs and matrixed or mirrored HDMI and HDBaseT outputs. The HDBaseT output
transmits video, embedded audio, and Ethernet over distances up to 330 feet (100 meters) to
the AT-HDR-EX-100CEA-RX receiver (available separately). The HDR-SW-52ED is HDCP 2.2
compliant and supports 4K/UHD video @ 60 Hz with 4:4:4 chroma sampling, as well as HDMI
data rates up to 18 Gbps. It is ideal for the latest as well as emerging 4K/UHD and HDR sources
and displays, and includes EDID management features, automatic input switching, and automatic
display control. Additionally, 4K downscaling to 1080p @ 60, 30, or 24 Hz is available for the
outputs when connected to an HD display. The HDR-SW-52ED can de-embed audio from an
HDMI input, or return audio from the HDR-EX-100CEA-RX receiver, to S/PDIF or balanced analog
audio outputs. This HDMI switcher can be controlled via Ethernet, RS-232, and IR.

The AT-HDR-SW-52ED 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-HDR-SW-52ED
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/16. If this occurs, refer to the AT-HDR-SW-
52ED User Manual for more information.
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.
IP Conguration
Switching the IP mode using the Front Panel
1. Make sure the AT-HDR-SW-52ED is powered.
2. Connect an Ethernet cable between the LAN port of the AT-HDR-SW-52ED and the Local
Area Network (LAN).
3. Press and hold the POWER button for approximately 15 seconds. Release the POWER
button once all the front-panel LED indicators begin to ash. The number of ashes will
indicate the currently selected IP mode. Refer to the table, below.
