AT-OME-EX-KIT-LT
The Atlona AT-OME-EX-KIT-LT is an HDBaseT extender for video up to 4K/60 4:2:0, plus
embedded audio, control, and USB over distances up to 130 feet (40 meters) for 4K/UHD, and up
to 230 feet (70 meters) for 1080p/60 video. Part of the Omega™ Series of integration products for
modern AV communications and collaboration, the OME-EX-KIT-LT is HDCP 2.2 compliant and
extends IR and RS-232 control signals. The integrated USB extension addresses the challenge
of connecting between USB devices at remote locations, and is ideal for software video
conferencing and touch or interactive displays. The transmitter includes a USB 2.0 host interface
for a PC, plus two peripheral devices such as a speakerphone, microphone, or keyboard and
mouse. The receiver provides two USB interfaces for devices such as a camera, soundbar, or
display.*
* Both the AT-OME-EX-TX-LT and AT-OME-EX-RX-LT are not compatible with the AT-UHD-
HDVS-300 system for extending USB.

Installation Guide
AT-OME-EX-KIT-LT
The AT-OME-EX-KIT-LT provides pass-through transport of RS-232 protocol and/or IR over
HDBaseT, which allows communication between a control system and an RS-232 or IR 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 for the RS-
232 connection.
3. Insert the TX, RX, and GND wires into correct terminal using one of the included 4-pin
captive screw connectors.
4. Repeat step 2 for the S and GND wires for the IR connection.
5. Insert the S (signal) wire in to the TX terminal and the ground wire to the GND terminal.
6. Tighten the captive screws to secure the wires in place. Do not over-tighten or use high-
torque devices to prevent damage to the connector block.
NOTE: Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5 for
ground. On some devices functions of pins 2 and 3 are reversed. Note that the
signal (S) pin for the IR is labeled as “TX” on the port.
