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 20

Captive Screw
The captive screw connectors allow you to cut cables to a suitable length, reducing cable clutter
while providing a more reliable connection.
Connecting
The captive screw connectors have
a contact bar that is adjusted to
compress the wire against the top
contact plate. Use the screws at the
top of the connector to compress
the wire against the contact plate.
When connecting the cables to the female captive screw connector it is important that the wires be
terminated correctly. The female captive screw connector has a contact plate at the top and must
have the wires touching it for signal to pass. When wired correctly (see picture A) the signal will pass,
incorrectly (see picture B) no signal will pass.
Female captive screw connectors are included: Power (see
picture 1), RS-232 (see picture 2), and IR (see picture 3).
The power cable
(picture 4) will have
exposed wires. Each
wire is encased in
a different colored
cover.

RS-232 pin out will be
determined by the RS-232
cable and will connect as
Rx (receiver), Tx (transmitter),
and (ground). (See picture 5)
Pin out color will differ
per RS-232 cable.

Note: The IR receiver and IR transmitter is optional for the UHD-SW-52ED. The compatible IR receiver (AT-IR-CS-RX)
and IR transmitter (AT-IR-CS-TX) can be purchased through atlona.com.
The wires of the emitter and receiver have been marked to differentiate the pin outs.
The included IR emitter has two wires: signal and ground. Signal will have a solid line and ground
will be blank. The IR emitter will plug into the IR OUT ports.
There are three wires on the IR receiver (sold separately): signal, ground, and power. Signal has a
dotted line, ground will be blank, and power will have a solid line. The IR receiver will plug into the
IR IN ports.

Tip (+)
Analog Audio
A captive screw analog audio connector is provided to ensure a more reliable and secure
connection. The captive screw connector supports balanced and unbalanced audio output.
Balanced audio connections use two signal wires and a ground to minimize interference to audio
signals. Unbalanced audio connections use one signal wire and a ground and are used if other
system components don’t support balanced signals.
Important! With unbalanced connections a jumper is needed between ground and negative to reduce noise
Note: Pin outs may vary, please refer to the audio device’s manual to ensure a correct connection.
Important! When terminating cables, please ensure exposed adjacent wires do not touch. This may result in a short
that can damage connected devices.

Ethernet
For convenience, the UHD-SW-52ED comes with DHCP on. This enables the switcher to be
connected to a network without knowing available IP addresses. If your network does not allow
dynamic IP addresses or if you are using the switcher with a TCP/IP control system, this feature may
be turned off and the IP address set using RS-232 commands or the webGUI.
WebGUI
Atlona has created an easy to use webGUI for initial setup and later changes to the configuration
of the switcher.
To begin, plug a LAN cable into the LAN port of the UHD-SW-52ED and the network switch, then
type the IP address of the unit into a web browser of a PC connected to the same network (as seen
below).
To find the switcher IP: 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 webGUI is no
longer used, the firewall and anti-virus can be re-enabled.
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 9). The username will always remain “root”.
Note: IP addresses may also be found using common free IP scanner software such as “Advanced IP
Scanner”

The home screen tab
will display the general
system information.
The Network Setup Page will allow the IP information to be changed. When a change is made the
screen will grey and the ability to save or cancel will display at the bottom.
Note: When DHCP is on, the IP address cannot be configured. Turn DHCP off to enable IP configuration.
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.
Login Mode has been added to provide a secure telnet login. Once Login Mode has been turned on
a username and password will be required on all IP connections to the switcher.
Note: Login mode should be in off position when the UHD-SW-52ED is used with control systems that do not support
passwords. If your control system supports password protection, you can turn login mode on. The webGUI
always requires a password.
Note: The username and password used in IP Login Mode will be the same login information as the webGUI.
