Introduction
Features
Package Content
The Atlona JunoX™ 451 (AT-JUNO-451) is a 4x1 HDMI switcher for high dynamic range (HDR)
formats. It 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. The JunoX 451 is ideal for residential
applications with the latest as well as emerging 4K/UHD and HDR sources and displays. It is
compatible with all video resolutions, audio formats, and color space formats supported in the
HDMI 2.0a specification, plus the ability to pass metadata for HDR content. The JunoX 451 includes
EDID management features and automatic input switching. It also supports the HDMI Audio Return
Channel for receiving digital audio from a television, and includes a TOSLINK digital audio output
for sending this audio to an AV receiver or soundbar. This JunoX Series HDMI switcher can be
controlled via Ethernet, RS-232, and IR. A handheld IR remote control is included.
Mounting
Mounting bracket x 2
The JunoX comes with mounting brackets that can be used to affix the unit to a table, desk, etc.
To affix the mounting brackets to the unit, use the four included screws. The bracket can be
affixed with the oval holes pointing to the bottom (for against the wall - picture A) or the oval holes
facing the top (for under tables - picture B).
Larger oval
hole will be
attached to
the wall/table.
Circular holes
will always be
attached to the
unit.

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

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.
A female captive screw connector
is included: RS-232/IR (see picture 1
& 2).
RS-232 IR
Clockwise Counter
Clockwise
Turn the screws clockwise to
raise the contact bar to the
upper contact plate and hold
the wires in place.
Turn the screws counter
clockwise to lower the
contact bar to release the
wires.

RS-232 pin out will be
determined by the RS-232
cable and will connect as
Rx (receiver), Tx (transmitter),
and (ground). (See picture 2)
The IR IN is connected by a ground and
a signal cable. The recommended use of
this port is with a 3rd part control system.
Atlona recommends using a AT-LC-CS-IR-
2M (sold separately) for easy connection.
Typical pin out:
2 - TX - Transmitter
3 - RX - Receiver
5 - GND - Ground
Pin out color will differ per RS-232
cable.

AMS & webGUI
Atlona provides two simple solutions for setup and control: a built in webGUI and the free software
AMS (AMS functionality coming soon).
To download AMS, go to http://atlona.com/product/at-sw-ams/
To get to the log in screen of AMS: type localhost:8080 into the web browser on the computer AMS is
running on. It will go straight to the log in for AMS.
GUI IP Address: may be found using an IP scanner software (e.g. Advanced IP Scanner)
*Atlona does not assume responsibility for damage caused by other programs installed into a computer, verify programs before installing*
A login screen will appear (this is the same log in for admin and general users). For the first login to AMS,
the username is “admin” and password is “admin123”. The login for the webGUI will be username
“root” and password “Atlona”.
Ethernet
Note: Press and hold the input button on the front panel to switch between static and DHCP IP address.
Two button flashes means the unit is in static mode and four button flashes means the unit is DHCP.
Static IP configuration will be: 192.168.1.254 - 255.255.255.0
For convenience, the JunoX 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 front panel.

RS-232 parameters
Set the baud rate, databit, parity, and stop bit of the system
The EDID tab enables the EDID settings to be changed or output EDIDs to be saved to memory.
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: STD passes the display’s EDID to the source
EDID Saved
Saves any connected display’s EDID to one of the four EDID memories of the JUNO-451
-Select the memory number to save the current output’s EDID to and press the save button
at the bottom of the page.
