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.

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.

The EDID Page enables the input preferred timing to be selected and HDCP compliance reporting
to be set.
HDCP selection allows the HDCP reporting of the input to be changed between compliant and
non-compliant
Note: This function is controllable through RS-232 and TCP/IP.
Note: UHD-SW-52ED protects HDCP encoded content and will not pass HDCP content to a non-HDCP compliant
device.
Note: Some devices flag all content as protected when connected to an HDCP compliant display. This prevents what
should be non-protected content from reaching devices (e.g. teleconference system) through the
UHD-SW-52ED.
Note: When HDCP reports as non-compliant, only user created content is transmitted. Protected content from all
sources (e.g. Blu-ray, AppleTV, etc) is blocked.
Note: To ensure compatibility, it is best to set the EDID to match the native resolution of the connected display and the
audio format of the connected sound system
Note: To use the analog audio output, a 2Ch EDID will need to be selected
EDID Saved
Save the current output’s EDID to memory. There are eight total EDID memories to save to.
Note: Internal EDIDs include audio EDIDs as well. 2Ch is two channel audio, MCh is multi-channel audio (including up
to Dolby TrueHD or DTS-HD Master Audio), DD is Dolby Digital, and DVI does not include audio.

Control
3rd Party Control
The UHD-SW-52ED is compatible with most 3rd party control systems. TCP/IP and RS-232
commands can be passed from 3rd party control systems to the UHD-SW-52ED through the LAN or
RS-232 port.
Note: The switcher can also convert TCP/IP commands to RS-232 commands which are then sent to the compatible
HDBaseT devices.
The UHD-SW-52ED can take either TCP/IP or RS-232 command protocol and transmit it to a
connected device: saving labor, cable, and control system ports.
The RS232zone command re-transmits RS-232 commands to the display through the compatible
HDBaseT receiver. The command may be initiated using either RS-232 or TCP/IP commands.
The Display On/Off command may be used to transmit a TCP/IP command by either RS-232 or TCP/
IP to a display.
Zone output parameter commands (for display control)
RS232para1[baudrate,data-length,parity,stop-bit]
Example: To change the output baud rate to 19200 use RS232para1[19200,8,0,1]
RS232zone1[command]
Once the switcher and zone output have been set up for the best communication, commands can be sent
to control the display. The commands will come from the user manual of the display or projector. The
commands and any carriage returns/line feeds in the commands will need to be placed in the bracket.
Example: To turn the display or projector on if the command is PWRON carriage return, use the command:
RS232zone1[PWRON carriage return]
Note: Use this command if the connected display uses a different baud rate
Note: Use this command if the connected control system does not output 115200
Switcher parameter command
CSpara[baudrate,data-length,parity,stop-bit] (data-length, parity, and stop-bit for switcher must be 8,0,1)
Example: To change the baud rate to 38400 use CSpara[38400,8,0,1]
Baud Rate
Default baud rate to control the switcher is 115200 and default baud rate to control the display or projector
is 9600. Note: For the display’s actual baud rate, refer to the owner’s manual
To change the baud rate of the switcher (for switcher control) or the zone output (for display/projector
control), the commands below will be needed
