OmniStream R-Type Dual-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.

Installation Guide
AT-OMNI-521
The AT-OMNI-521 provides either RS-232 or IR over IP. RS-232 allows communication between
an automation system and an RS-232 device. IR supports either an IR extender or IR emitter.
The top three terminals must be used. Therefore, only one communication protocol can be used
at a time. These steps are 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, 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.

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.
The AT-OMNI-521 is shipped in DHCP mode. If a DHCP server is not found within 60 seconds,
the unit will automatically be placed in Auto IP mode and will be assigned an IP address within
the range 169.254.xxx.xxx. If this occurs, a static IP address can be assigned to the decoder,
allowing it to be access on the network.
1. Disconnect the AT-OMNI-521 from the network.
2. Make sure that the decoder is powered. Power is supplied by connecting the an Ethernet
cable from the ETHERNET port to a PoE-capable switch. If a PoE-capable switch is not
available, a PoE injector (not included) will need to be connected between the LAN port on
the PC and the ETHERNET port on the AT-OMNI-521.
3. Click Start > Settings > Control Panel > Network and Sharing Center.
4. Click Change adapter settings.
5. Right-click on the adapter that is used to establish a wired connection to the network, and
select Properties from the context menu.
6. Under the Ethernet Properties dialog box, select Internet Protocol Version 4 and then
click the Properties button.
7. Click the Use the following IP address radio button.

IP Conguration
IMPORTANT: Before continuing, write down the current IP settings in order to
restore them, later. If Obtain an IP address automatically and Obtain DNS server
automatically are selected, then this step is not required.
IMPORTANT: If the network switch is not PoE capable, a PoE injector
(purchased separately) must be used.

9. Enter the desired static IP address or the IP address provided by the network administrator.
If the PC does not require Internet access or if a statically-assigned IP address is being
used, then an IP address of 169.254.xxx.xxx can be entered.
10. Set the subnet mask to 255.255.0.0.
11. Click the OK button then close all Control Panel windows.
12. Reconnect the AT-OMNI-521 to the network.

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.

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.
• If the switch is not PoE-capable, then make sure a
PoE injector (not included) is connected between the
ETHERNET port on the AT-OMNI-521 and the LAN port
on the switch.
• Check the Ethernet cable for possible damage or loose
connections.
LINK indicator is red. • Check the Ethernet cable for possible damage or loose
connections.
