OmniStream 122 Dual-Channel Networked AV Decoder
AT-OMNI-122
The Atlona OmniStream™ 122 (AT-OMNI-122) is a networked AV decoder with two independent
decoding channels and two independent HDMI 2.0 outputs supported resolutions up to 4K @
60Hz and HDR (High Dynamic Range), plus audio embedding / de-embedding, and RS-232 or IR
control pass-through. It is part of the OmniStream Series, designed for high performance, exible
distribution of AV over standard o-the-shelf Gigabit Ethernet switches in commercial audio
visual applications. It features advanced high-quality VC-2 visually lossless video decoding
technology with user selectable video-quality optimization engines designed for computer-
generated imaging, or motion video content. The Atlona OmniStream™ 122 achieves extremely
low, sub-frame latency when paired with OmniStream Encoders. This dual-channel decoder is
housed in a half-width rack with front-to-back air ow enclosure, and is ideal for high-density,
compact installation in a centralized equipment location.

Operating Notes
• Atlona recommends using the Atlona Management System (AMS) which provides discovery,
management, and conguration assistance. AMS is a free application that can be
downloaded from the Atlona web site at http://atlona.com/product/at-sw-ams/.
• This product includes a built-in web interface, which can be used to manage and congure
this device.
• OmniStream uses mDNS as the discovery mechanism. In order for mDNS to function
properly, there must not be restrictions applied to the network. VPN can be used to
connect to a computer that is running AMS, on the same network. However, VPN cannot
be used when AMS is running on the local machine.

AT-OMNI-122
The AT-OMNI-122 decoder includes two
mounting brackets and four mounting screws,
which can be used to attach the unit to any at
surface.
1. Using a small Phillips screwdriver, remove
the two screws from the left side of the
enclosure.
2. Position one of the mounting brackets, as
shown below, aligning the holes on the
side of the enclosure with one set of holes
on the mounting bracket.
3. Use the enclosure screws to secure the
mounting bracket to the enclosure.
4. To provide added stability to the mounting
bracket, use two of the included screws
and attach them to the two holes, directly
below the enclosure screws, as shown
above.
5. Repeat steps 1 through 4 to attach the
second mounting bracket to the opposite
side of the unit.
6. Mount the unit using the oval-shaped
holes, on each mounting bracket. If using
a drywall surface, a #6 drywall screw is
recommended.

1. Connect an Ethernet cable from the ETHERNET 1 and ETHERNET 2 ports on the decoder
to a PoE-capable switch on the Local Area Network (LAN). Note that if a PoE-capable
switch is not available, the 48V DC power supply (sold separately) must be connected to the
decoder.
2. Connect HDMI cables from each UHD/HD display to the HDMI OUT ports on the decoder.
3. If using RS-232, connect the 6-pin captive screw connector to the RS-232 port on the
decoder.
4. The PWR indicator, on the front panel, display the power status of the decoder. When the
decoder is powered, using either PoE or the optional 48V DC power supply (not included),
the LED initially turns red. After a few moments it will turn amber, and nally green.
Installation
The AT-OMNI-122 is powered by PoE (Power over Ethernet), when connected to a PoE-capable
switch. If a PoE-switch is not used, then the optional 48 V power supply (Atlona part no. AT-PS-
48083-C) can be purchased, separately. Insert the positive and negative leads, from the power
supply, into the terminals of the 2-pin captive screw connector block, as shown. The orange
2-pin captive screw connector block is included with the OmniStream power supply package.
Power Supply (optional)
IMPORTANT: The external power supply must be connected to the decoder
when embedding and de-embedding audio using the AUDIO IN and/or AUDIO
OUT ports.

The AT-OMNI-121 provides transport of RS-232 protocol over IP which allows communication
between a control system and an RS-232 device. This step is optional.
1. Use wire strippers to remove a portion of the cable jacket.
2. Remove at least 3/16” (5 mm) from the insulation of the RX, TX, and GND wires.
3. Insert the TX, RX, and GND wires into correct terminal on the included push spring
connector. If using non-tinned stranded wire, press the orange tab, above the terminal,
while inserting the exposed wire.
NOTE: Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5 for
ground. On some devices, the function of pins 2 and 3 are reversed.

The AT-OMNI-122 provides the ability to embed 2-channel analog audio on the HDMI OUT port
or de-embed HDMI audio on the AUDIO OUT port. De-embedded HDMI audio is downmixed to
2-channel PCM. This step is optional.
• If AUDIO IN or AUDIO OUT will be used, then connect the included 5-pin captive screw
connectors, as shown in the following examples:
• If both AUDIO IN and AUDIO OUT ports will be used, then connect the included 5-pin push
spring connectors, as shown on the next page.

1. Launch a web browser and enter the IP address of AMS, in the address bar.
2. Enter the required login credentials.
3. Click the Login button.
4. The AMS Dashboard will be displayed.
5. Click the icon, in the upper-left corner of the AMS Dashboard.
6. Click Devices from the y-out menu.
7. Click the Unassigned option.
All available decoders will be displayed under the Unassigned category. When a decoder
is unassigned, it means that it has not been assigned to a site, building, and/or room. Refer
to the AMS User Manual for more information on these topics.
If a DHCP server is not found within 60 seconds, the decoder will be placed in Auto IP mode
and assigned an IP address within the range of 169.254.xxx.xxx. If this occurs, congure
the network interface of the computer that is running AMS, located on the same subnet
(169.254.xxx.xxx, subnet mask 255.255.0.0). Refer to User Manual for more information.
If no OmniStream decoders are found, then verify the following:
• The computer that is running AMS must be on the same network as the OmniStream
device.
• Remove any network restrictions that may be in place. In order for mDNS to function
properly, there must not be restrictions applied to the network.

Troubleshooting
Problem Solution
PWR indicator is o. • If using a PoE (Power-over-Ethernet) switch, make
sure that the port on the switch that is connected to
the decoder, has PoE enabled. When the decoder is
powered using PoE, the PWR indicator will be green.
• Check the Ethernet cable for possible damage or loose
connections.
• Connect the optional 48V DC power supply (available
from atlona.com) to the decoder. When using an external
power supply, the PWR indicator will be red.
LINK indicator is red. • Connect an Ethernet cable to the ETHERNET port(s).
• Check the Ethernet cable for possible damage or loose
connections.
OmniStream decoders are
not displayed in AMS.
• Verify that AMS and the decoder are on the same
network.
• If a DHCP server is not found within 60 seconds, the
decoder will be placed in Auto IP mode and assigned
an IP address within the range of 169.254.xxx.xxx. If
so, then connect a laptop directly to the decoder and
congure a static IP address for the decoder.
• Check the Ethernet cable for possible damage or loose
connections.
• Make sure that mDNS is enabled on the network.
Also, in order for mDNS to function properly, there must
not be any restrictions applied to the network.
Analog audio embedding/
de-embedding is not
working.
• The power supply (AT-PS-48083-C) must be connected
to the decoder. Contact Atlona to purchase this power
supply.
