OmniStream 112 Dual-Channel Networked AV Encoder
AT-OMNI-112
The Atlona OmniStream™ 112 (AT-OMNI-112) is a networked AV encoder with two independent
channels of encoding for two HDMI 2.0 sources up to 4K @ 60 Hz and HDR (High Dynamic
Range), plus embedded audio 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. The OmniStream
112 is HDCP 2.2 compliant and ideal for the latest Ultra High-Denition and HDR sources. It
features advanced high-quality VC-2 visually lossless video compression technology with user
selectable video-quality optimization engines designed for computer-generated imaging, or
motion video content. The Atlona OmniStream™ 112 achieves extremely low, sub-frame latency
when paired with OmniStream Decoders. This dual-channel encoder 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.

Installation Guide
AT-OMNI-112
The AT-OMNI-112 encoder 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.

PWR indicator
1. Connect an Ethernet cable from the ETHERNET 1 and ETHERNET 2 ports on the encoder
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
encoder.
2. Connect an HDMI cable from each UHD/HD source to the HDMI 1 and HDMI 2 ports on the
encoder.
3. If using RS-232, connect the included 6-pin captive screw connector to the RS-232 port on
the encoder.
4. The PWR indicator, on the front panel, display the power status of the encoder. When the
encoder 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-112 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.

RS-232
The AT-OMNI-112 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, following the wiring diagram below. 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.

Installation Guide
AT-OMNI-112
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 fly-out menu.
7. Click the Unassigned option.
All available encoders will be displayed under the Unassigned category. When a encoder 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 encoder will be placed in Auto IP mode
and assigned an IP address within the range of 169.254.xxx.xxx. If this occurs, configure
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 encoders 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 encoder, has PoE enabled. When the encoder 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 encoder. 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 encoders are
not displayed in AMS.
• Verify that AMS and the encoder are on the same
network.
• If a DHCP server is not found within 60 seconds, the
encoder 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 encoder and
congure a static IP address for the encoder.
• 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.
