AT-OMNI-311
The Atlona OmniStream™ USB 311 (AT-OMNI-311) works in tandem with the OmniStream USB
324 (AT-OMNI-324) for extending USB from peripheral devices to a PC over Gigabit Ethernet.
The OmniStream USB 311 interfaces with a PC or other host device, while the OmniStream
USB 324 features a four-port USB hub for peripherals. The OmniStream USB over IP system
is compatible with USB 2.0 data rates of up to 480 Mbps. It can be used with high-bandwidth
devices including cameras, speaker phones, microphones, and DSPs, plus standard USB HID
class devices such as a keyboard, mouse, or touch display. Up to seven OmniStream USB 324
units can be simultaneously paired to an OmniStream USB 311. Additionally, USB routing over
the network can be managed using Atlona Management System (AMS) 2.0.
OmniStream USB products can be used in a wide variety of system design scenarios for soft
codec conferencing and remote keyboard / mouse control. They are ideal for integrating USB
audio and video devices as part of a fully IP-based meeting room system,in conjunction with
OmniStream AV over IP devices and the Velocity Control System.

AT-OMNI-311
Installation
1. Place the AT-OMNI-311 next to the USB host device and connect a USB cable from the
HOST port to the host computer.
The AT-OMNI-311 can be connect to a AT-OMNI-324 (not included) in one of two ways:
Over Network
a. Connect an Ethernet cable, up to 330 feet (100 meters), from the LAN port on the
AT-OMNI-311 to the network switch.
b. Connect an Ethernet cable, up to 330 feet (100 meters), from the receiver (AT-
OMNI-324; not included) to a switch on the same network.
NOTE: When connecting a transmitter and receiver, over a network,
the cable distance between hops must not exceed 330 feet (100 meters)
for copper connections (ber extenders can be used to create longer
runs). For example, connecting up to ve network switches, using copper
cabling, can be used to extend USB up to 1980 feet (600 meters).
Direct Connection
a. Connect an Ethernet cable, up to 330 feet (100 meters), from the LAN port of the
AT-OMNI-311 directly to the AT-OMNI-324 (not included).
2. The AT-OMNI-311 is powered by the host computer. No external power supply is required.
3. Refer to the Installation Guide for the AT-OMNI-324 for additional connection instructions
and the User Manual for detailed information.
4. Refer to Pairing (page 4) for instructions on pairing a transmitter and receiver.
