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 HDBT is ideal for receiving 4K HDR

Atlona UHD-PRO3, UHD-CAT, and SW Series for data rates up to 10 Gbps. It includes EDID
management features and automatic input switching. The JunoX 451 HDBT 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 switcher can be controlled via Ethernet, RS-232, and IR. A handheld IR remote control is
included.
The Atlona JunoX™ 451 (AT-JUNO-451) provides the same features at the AT-JUNO-451-HDBT,

Installation Guide
AT-JUNO-451 / AT-JUNO-451-HDBT
RS-232 / IR Connector
Both the AT-JUNO-451 and AT-JUNO-451-HDBT provide RS-232 and IR control, using the
included four-pin captive screw connector. Electrical IR or RS-232 signals, from a control
system, can be used for control. Atlona recommends the AT-LC-CS-IR-2M (sold separately) for
easy connection to the captive screw connector.
1. Use wire strippers to remove a portion of the cable jacket.
2. Remove at least 3/16” (5 mm) from the insulation of each wire.
3. Insert the wires into the correct terminal on the included captive screw connector, as shown
below.
4. Tighten the screws to secure the wires. Do not use high-torque devices as this may
damage the screws and/or connector.
Both the AT-JUNO-451 and AT-JUNO-451-HDBT
include an IR remote control that can be used to
operate the unit from a remote location.
