ARC enables a source connected to a display to route audio back to the switcher and send the de-embedded
audio out the S/PDIF output.
1. Check to be sure the display supports ARC
2. Enable ARC on the HDMI output of the switcher through RS-232 (command ARC on), TCP/IP, or webGUI
3. Connect the HDMI output port of the switcher to the ARC labeled input port on the display
NOTE: The switcher must be connected to the display’s HDMI ARC input
Note: Works well with audio from ARC enabled “Smart” televisions
4. Connect the source to a non ARC HDMI input port on the display
5. Connect the S/PDIF port to an AVR or Zone Amp

Connecting
Captive screw connectors are an added feature on the UHD-SW. The Captive screw connectors allow you to
cut cables down to a suitable length, reducing cable clutter while providing a more reliable connection.
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.
The power cable (picture 1) will have exposed wires. Each wire is encased in a different colored cover. Female
captive screw connectors are included: Power (see picture 2) and RS-232 (see picture 3).

TCP/IP
For convenience, the UHD-SW 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 UHD-SW with a TCP/IP control system, this feature may be turned
off and the IP address set using RS-232 commands or the webGUI.
TCP/IP WebGUI
Atlona has created an easy to use WebGUI for initial setup and later changes to the configuration
of the UHD-SW.
To begin, plug a LAN cable into the LAN port of the UHD-SW and your network, then type the IP
address of the UHD-SW 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 GUI 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”
