OmniStream 121 Single-Channel Networked AV Decoder
AT-OMNI-121
The Atlona OmniStream™ 121 (AT-OMNI-121) is a networked AV decoder for an OmniStream- encoded video stream up to 4K/UHD, as well as embedded audio and RS-232 control. OmniStream is designed for distributing AV over Gigabit Ethernet in enterprises and other large­scale installations. The OmniStream 121 features SMPTE VC-2 visually lossless compression with extremely low, sub-frame latency, as well as AES-128 encryption and SMPTE 2022-5 forward error correction. For professional AV integration, it includes an HDMI output, 4K/UHD scaling with 4:4:4 processing, aspect ratio control, multi-channel PCM audio downmixing, audio embedding and de-embedding, and more. This decoder is housed in a half rack width enclosure. The OmniStream 121 can conveniently be powered over the network through Power over Ethernet (PoE), as well as from local AC power.

Operating Notes
OmniStream requires 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/
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.

RS-232
The AT-OMNI-121 provides RS-232 over IP which allows communication between an automation 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 captive screw connector, following the wiring diagram below.
Note that the included 6-pin push spring connector can be used, if desired, in place of the captive screw connector. However, only the RS-232 1 port is available on the decoder.
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.

Audio
The AT-OMNI-121 provides the ability to embed analog audio on the output stream and output downmixed 2-channel PCM, using the included captive screw or push spring connectors. This step is optional.
IMPORTANT: Audio embedding and de-embedding, using the analog audio
outputs, requires the optional OmniStream power supply (AT-PS-48083-C).
If AUDIO IN or AUDIO OUT will be used, then connect the included 5-pin captive screw connectors, as shown below.

NOTE: Unbalanced XLR audio requires Pin 1 and Pin 3 to be connected. The same wiring applies to both captive screw and push spring connectors.
Installation
1. Connect an Ethernet cable from the ETHERNET port 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 an HDMI cable from the HD/Ultra HD display to the HDMI OUT port 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.

Mounting Instructions
The AT-OMNI-121 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.

Installation Guide
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.
NOTE: Mounting brackets can
also be inverted to mount the
unit under a table or other at
surface.

Conguration
By default, the AT-OMNI-121 is set to DHCP mode. In this mode, each decoder that is connected to the Local Area Network (LAN) will automatically be assigned an IP address by the DHCP server, allowing communication with AMS. AMS will only be able to discover the
decoders if they are on the same VLAN. Refer to the User Manual for details on conguring
decoders to static IP mode.
To determine the IP address of the decoder, use the Atlona Management System (AMS) app. AMS is available only for the Windows® Operating Sytem. If necessary, mDNS/Bonjour can also be used to discover the IP address of the decoder.
1. Launch the Atlona Management System app.
2. Launch a web browser and enter localhost:8080 in the address eld.
3. Enter the login information on the AMS web page, then click the Login button.
Login: admin Password: admin123
4. Under the Domain View panel, locate the IP address for the decoder. Decoders will be labeled as OMNI-121.

PWR indicator is o. If using a PoE (Power-over-Ethernet) switch, make
LINK indicator is red. Connect an Ethernet cable to the ETHERNET port(s).
OmniStream decoders are not displayed in AMS.
Analog audio embedding/ de-embedding is not working.
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.
Check the Ethernet cable for possible damage or loose connections.
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.
The power supply (AT-PS-48083-C) must be connected to the decoder. Contact Atlona to purchase this power supply.
