OmniStream R-Type Single-Channel Networked AV Decoder
AT-OMNI-521
The Atlona OmniStream™ R-Type (AT-OMNI-521) is a networked AV decoder for an
OmniStream-encoded video stream up to UHD @ 60 Hz and HDR, plus embedded audio and
RS-232 or IR control pass-through. It is part of the OmniStream R-Type Series, designed
for high performance, exible distribution of AV over Gigabit Ethernet in residential and light
commercial applications. The OmniStream 521 is HDCP 2.2 compliant and ideal for the latest
as well as emerging UHD and HDR displays. It features visually lossless compression with
pristine-quality video and graphics performance, plus extremely low, sub-frame latency from
encode to decode – critical for demanding applications such as gaming. This decoder includes
an HDMI output, high performance upscaling and downscaling, aspect ratio control, and video
wall processing, plus presentation enhancement features such as logo insertion and scrolling
on-screen text.

Operating Notes
• This product is powered using PoE (Power over Ethernet) and must be connected to a
PoE-capable network switch. If the network switch is not PoE-capable, a PoE injector
(purchased separately) must be used.
• Atlona recommends using the Velocity with Integrated AMS which provides discovery,
management, and conguration assistance. Velocity with Integrated AMS is a free
application that can be downloaded from the Atlona web site at http://atlona.com/product/
at-ams-sw/.
• 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.

Installation Guide
AT-OMNI-521
The AT-OMNI-521 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 port on the decoder to a PoE-capable
switch on the Local Area Network (LAN).
2. Connect an HDMI cable from the HDMI OUT port to a UHD/HD display.
3. If using RS-232 and/or IR, connect the included 6-pin captive screw connector to the RS-
232 / IR 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 Guide
AT-OMNI-521
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, following the wiring diagram below. If using non-tinned stranded wire, press the
orange tab, above the terminal, while inserting the exposed wire.
1. Use wire strippers to remove a portion of the cable jacket.
2. Remove at least 3/16” (5 mm) from the insulation from each of the two wires.
3. Insert the wires into the correct terminal on the included push spring connector, following
the desired wiring diagram below.
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-512 provides transport of RS-232 protocol over IP which allows communication
between a control system and an RS-232 device. The top three terminals must be used. This
step is optional.
The same port that provides RS-232 connections also supports either an IR extender or IR
emitter. The top three terminals must be used. This step is optional.

Installation Guide
AT-OMNI-521
1. Launch a web browser and enter the IP address of Velocity, in the address bar.
2. Enter the required login credentials.
3. Click the Login button.
4. The Velocity with Integrated AMS Dashboard will be displayed.
5. Click the icon, in the upper-left corner.
6. Click Management >AMS Device Manager from the y-out menu.
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 Velocity 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 Velocity 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.

Accessing devices using the built-in Web Server
1. Identify the desired decoder by locating the MAC address on the bottom of the unit.
In the following example (refer to your unit for the actual address), the label indicates that
the MAC address for the physical interface is B8:98:B0:01:F7:EB.
MAC address
2. Connect a PC to the same network where the OmniStream encoders/decoders are
connected.
3. Locate the IP address, matching it with the MAC address of the device, using an IP scanner
or ARP.
4. Launch the desired web browser and enter the IP address of the decoder in the address bar.
5. Enter the username and password. Note that the password eld will always be masked.
The default credentials are:
Username: admin
Password: Atlona
NOTE: Atlona recommends changing both the username and password for
security purposes. Refer to the OmniStream User Manual for more information.

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.
LINK indicator is red. • Connect an Ethernet cable to the ETHERNET port.
• Check the Ethernet cable for possible damage or loose
connections.
OmniStream decoders are
not displayed in Velocity
with AMS Integration.
• 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.
To access the decoder, congure a static IP on the PC
within the same IP range, then connect the PC directly
to the decoder and congure a static IP address for the
decoder. This static IP address must be within the same
IP range that is used by the Velocity with AMS Integration
software. Otherwise, the decoder will not show up.
• 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.
