Introduction
The Atlona AT-UHD-CAT-4 is a 4K/UHD HDMI to HDBaseT™ distribution amplifier featuring
pass-through HDMI input connections, four HDBaseT outputs and display control capability.Each
output transmits AV and control signals up to 230 ft. (70 m) @ 1080p and 130 ft. (40 m) @ 4K/
UHD. Features include 4K/UHD @ 60 Hz with 4:2:0 color subsampling, HDCP 2.2 compliance, EDID
management, and PoE for powering remote receivers. A wide variety of consumer and commercial
displays may be controlled by the AT-UHD-CAT-4 using CEC.Designed for commercial distribution
applications, the AT-UHD-CAT-4 is control system-friendly and integrates with any TCP/IP, RS-232,
or IR control system and features a 1U, half-rack width enclosure with external, international power
supply.

Category Cable
For the category cables used in the installation of these products, please be sure to use a 568B
termination as pictured below:
Connector type and size is very important to ensure extenders work correctly. Please use the
matching cable type with the correct RJ45 connector.
CAT5e cables should use only CAT5e RJ45 connectors
CAT6 cables should use only CAT6 connectors
CAT6a cables should use only CAT6a connectors
CAT7 cables should use only CAT7 connectors
Using the wrong size connectors may result in interference causing loss of signal.
Important! “EZ RJ45 connectors” are not recommended with HDBaseT extenders. Doing so may result in interference
with audio and video transmission.
Use the table below to verify the best category cable for the installation.
Important! 4K (UHD) signals are sensitive to cable quality and installation technique. It is recommended to
use CAT6a/7 solid core cables for best results.
Note: For cable distances see the specifications on page 15

A login screen will appear (this is the same log in for admin and general users). For the first log in (and future
admin changes) the username is “root” and password is “Atlona”.
Note: Only the admin password can be changed (see page 8). The username will always remain “root”.
TCP/IP
For convenience, the UHD-CAT comes with DHCP on. This enables the switcher to be connected to
a network without concern for overlapping IP addresses with other devices on the network. If your
network does not support DHCP, this feature may be turned off and the IP address set using RS-
232 commands or the webGUI.
Note: If your system is controlled using IP, it is strongly recommended that you disable DHCP and select a unused IP
address so that your system controller doesn’t lose contact with the switcher.
TCP/IP WebGUI
Atlona has created an easy to use webGUI for initial setup and later changes to the configuration
of the UHD-CAT.
To begin, connect the LAN port of the UHD-CAT to your network. Type the IP address of the UHD-
CAT into the web browser of a PC connected to the same network (as seen below).
To find the switcher IP: Select “Network Status” within the OSD menu or use RS-232 command “IPCFG”.
Important: If any stability issues are experienced, disable any anti-virus or firewall that may interfere with
network communication to the switcher. Once set up is done and the switcher GUI is no
longer being used, the firewall and anti-virus can be re-enabled.

Network: IP address, netmask, gateway, and telnet port can be set to any settings compatible
with your network. The Netmask and Gateway must match your existing network
settings
IP Mode -
Static: Set a fixed IP address
Note: For a stable connection when using a control system, it is best to set up a static IP. As you select
an IP address, make certain no other devices on your network are using that IP address
DHCP: Dynamic Host Configuration Protocol will automatically select an IP address
on the network that is not already in use
Telnet Login Mode - Turn on/off - requires a password to adjust settings
Telnet Timeout - Set the auto log-off time between 1 and 3600 seconds
Broadcast - Turn on and off the feedback through all control ports
Power - Turns the unit on/off
Lock - Locks or unlocks the front panel buttons
Power button mode - Set the power button to turn the device, display (via CEC), or both on/off
Reset to Default - Reset the device to factory settings
Firmware Update - Use this feature to find and load the MCU firmware to the switcher
Note: Firmware can be found and downloaded from http://www.atlona.com/product/AT-CAT-4/
page under the firmware tab
Valens Update - Use this feature to find and load the Valens firmware to the Valens chips

CEC
Power -
On: Sends a command over HDBaseT to the HDMI output of the connected receiver to turn
the connected display on
Off: Sends a command over HDBaseT to the HDMI output of the connected receiver to turn
the connected display off
Note: Consumer Electronics Control (CEC): Atlona does not guarantee the function of CEC with all televisions. We can
confirm proper operation with many current Samsung, Panasonic, and Sony TVs. Many manufacturers do not
support the CEC “Off” command when sent from a source and older TVs use proprietary commands. Atlona only
supports those TVs that follow CEC command structure from HDMI 1.2a and support the “off” command when
issued by a source. We encourage any dealer to get evaluation product from Atlona prior to designing a system
around this control technology or be prepared to use other methods to control their displays if Atlona CEC is not
compatible with the installed displays.
Note: Together, CEC and HDBaseT output audio control provide a simple solution for complete audio and
video control, without the need for IP, RS-232, or spending extra programming time.
