AT-OME-MS42 9
The Atlona AT-OME-MS42 is a 4x2 matrix switcher with HDMI, USB-C, and DisplayPort inputs, plus HDMI and
HDBaseT outputs. Part of the Omega™ Series of integration products for modern AV communications and
collaboration, the OME-MS42 is HDCP 2.2 compliant and features HDBaseT extension for video up to 4K/60 4:2:0,
plus embedded audio, control, Ethernet, and USB over distances up to 330 feet (100 meters). All inputs and the
local HDMI output support 4K HDR and 4K/60 4:4:4 at HDMI data rates up to 18 Gbps. Additionally, 4K downscaling
to 1080p @ 60, 30, or 24 Hz is available for the HDMI output when connected to an HD sink. 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 OME-MS42 includes USB 2.0 and USB-C interfaces for
three host PCs, plus two peripheral devices such as a camera, microphone, speakerphone, or keyboard and mouse.
It is ideal for video conferencing and many other 4K presentation applications with the OME-EX-RX receiver and
OME-SR21 scaling receiver.

The AUDIO OUT connector on the AT-OME-MS42 provides a separate output for balanced audio using XLR
connectors. Use the included 5-pin captive-screw terminal block. Balanced audio connections use two signal wires
and a ground to minimize interference in audio signals. Unbalanced output audio is not recommended and may
require additional equipment.

PWR LED ashes Description
Four DHCP mode
Two Factory Static IP mode (IP address set to 192.168.1.254)
The AT-OME-MS42 is shipped with DHCP enabled. Once connected to a network, the DHCP server (if available),
will automatically assign an IP address to the unit. If the AT-OME-MS42 is unable to detect a DHCP server within 15
seconds, then the unit will use a self-assigned IP address within the range of 169.254.xxx.xxx.
Use an IP scanner, along with the MAC address on the bottom of the unit, to identify the unit on the network.
If a static IP address is desired, the unit can be switched to static IP mode. The default static IP address is
192.168.1.254.
1. Make sure the AT-OME-MS42 is powered by connecting the included power supply.
2. Press and hold the IP MODE button, on the rear of the unit.
3. Release the button once the LED indicator, next to the IP MODE button, begins to ash green. The number of
ashes will indicate the currently selected IP mode.
Setting the IP Address using the Web Server
Refer to the Changing the Network IP Mode (page 42) in the built-in web server, to set the AT-OME-MS42 to either
DHCP or static IP mode. In order to access the web server, the IP address of the AT-OME-MS42 must be known.
By default, the AT-OME-MS42 is set to DHCP mode and will automatically be assigned an IP address by a DHCP
server.
Displaying the IP Address
Press and release the IP MODE button to display the IP address of the AT-OME-MS42 on the display connected to
the HDMI OUT port. The IP address will be displayed in the upper-left corner of the display.

AT-OME-MS42 20
Device Operation
This mode is desirable when integrating the AT-OME-MS42 with a video conference system. In this mode, both
static input and output routing are specied. Auto-Switching (page 22) must be enabled. However, the specied
static input will be removed from the auto-switching pool. For example, if the HDMI IN 3 port is specied as a static
input, then auto-switching will “skip” this port when auto-switching.
