Thanks for choosing Liberty AV’s DL-SCU33-SW Web-Conferencing Room Switcher! The switcher/
hub (DL-SCU33-SW) is a multi-format switcher that provides AV switching and USB routing for BYOM
(bring your own meeting) devices to connect to dedicated cloud-based room systems. Users will be
able to easily bring-their-own-meeting (i.e. Teams desktop client) in spaces running dedicated cloud-
based room clients (i.e. Zoom room client). The devices allows USB peripherals to switch between
dedicated room systems and BYOM devices such as laptops. In addition, when BYOM is enabled,
users can integrate their laptop into a dual screen environment by mirroring the laptop’s output. The
device’s compact size allows for exible mounting locations such as behind a display or underneath
the table; mounting brackets come included. The USB-C port provides up to 60 watts of charging
power creating the all-in-one cable experience. Built-in USB hub provides easy connection of devices
like cameras, microphones, and speakers. Easily switch between modes from third-party devices
ranging from a keypad/button or leave it set to auto switch. Integrated digital I/O ports and the built-
in scheduler provide users with touchless display control using the built-in CEC controller. The
control software has an event-driven architecture allowing conguration to be a breeze. The existing
HDMI presentation cable can be used in either, dedicated or BYOM mode; no need to add another
HDMI cable.
The collaboration switcher simplies meeting room and presentation space system integration
by providing two video modes (BYOM mode and Standard mode) with three HDMI inputs, one
USB-C input and three HDMI outputs. The USB-C input supports video, data (USB host) and power
charging up to 60w. There is a 4-port USB client hub built with 3 USB host ports that can be switched
independently.
The switcher supports resolution up to 4K@60Hz@4:4:4, is HDCP 2.2-compliant and has a built-in
USB 3.0 switching hub for control and integration of USB devices such as USB cameras
and microphones.
The switcher supports auto switching and allows users to control the system functionality via TCP/IP,
Digital I/O, contact and front panel.

1. USB-C or HDMI of LAPTOP IN will switch to 2 HDMI outputs of DISPLAY OUT.
2. USB clients will switch to the USB host connected to the LAPTOP IN (USB-B port if the HDMI source is
connected OR, the USB-C port.
3. Audio output will be extracted from USB-C or HDMO of the LAPTOP IN.
*Note: The HDMI signal will be selected if both USB-C and HDMI of LAPTOP IN are connected.
** Note: The USB-C will need to be set to manual or enabled for BYOM. By default, the USB-C port will
be set for Standard Mode.
Standard Mode
1. 2 HDMI inputs of ROOM PC IN will switch to DISPLAY separately. USB-C or HDMI of LAPTOP IN will
switch to SHARE OUT.
2. USB clients will switch to the USB-B host of ROOM PC IN.
3. Audio output will de-embedded from 1-HDMI of ROOM PC-IN.
Manual Switching
When the DIP switch next to the LAPTOP-IN is selected to MANUAL, the switcher is now in manual
switching mode.
One can select BYOM or STANDARD mode via:
• Web GUI landing page
• Occupancy sensor connected via digital i/o
• Control from a third-party device
• Predened schedule
• Push button connected via contact closure can select BYOM or STANDARD mode via web GUI

Auto Switching
When the DIP switch of rear panel is selected to AUTO, the switcher is in auto-switching mode. BYOM or
STANDARD mode will be automatically selected by signal detected according to the following rules:
1. If the USB-C or USB-B signal of LAPTOP IN is detected, BYOM mode is selected.
2. If neither the USB-C or USB-B signal of LAPTOP IN is detected, STANDARD mode is selected.
The DL-SCU33-SW collaboration switcher provides two modes to select from which allows users to
choose from either a dedicated in-room PC running software or from their own laptop that they
brought into the meeting space. The switcher is NOT a matrix switcher, and does not allow for custom
routing of AV and USB signals.

Dedicated Room System (Standard): The collaboration switcher gets installed in series within the
dedicated room systems signal chain, ideal for post- or pre-install and is purpose-built for single or
dual screen enviroments. The shared content output allows for a dedicated room system to use the
connected HDMI OR USB-C cable for wired HDMI screen sharing, injecting the content into the software
running on the dedicated PC. This uses an HDMI to USB capture card to communicate between local
device content with the application such as Zoom or a Zoom Room.
Note: The HDMI content sharing output is optional and is not required for system functionality.

In Standard mode, the HDMI signal from the laptop connection will route out of the SHARE OUTPUT.
This is intended for wired content sharing when using third-party UC software such as Zoom. Certain
UC software companies allow laptop content to be directly shared to the room system for screen share
during a video call or locally.
The USB-C connection will send adequate power to charge the device, receive audio and 4K@60Hz video
signals for video output and transferring USB data. Note: A full-featured USB-C cable must be used along
with a laptop with a full-featured USB-C port.

connection provides the ability for users to connect to the meeting space assets from their own device,
such as the display, amplier, camera and microphone OR be used for wired content sharing within a
dedicated room system.
1. CONTENT: USB-C or HDMI from the LAPTOP IN connection will switch to the 2 HDMI outputs from
DISPLAY OUT. The content will be mirrored to each output. The switcher can be wired for dual or single
screen applications.
2. USB: The USB devices connected to the USB 3.0 section client ports will switch to the laptop USB host
(USB-B port ties to HDMI or USB-C port if USB-C source is connected).
Note: HDMI signal will be selected if both USB-C and HDMI of LAPTOP IN are connected.

The DL-SCu33 provides automation through an event-driven architecture where actions are executed as
events happen.
Event:apply to the cases you want something to happen (for instance turning a display ON).
Label: freely select any name for your event. We have input generic text that can be left alone.
Trigger: is the action that starts an automation. These can be a user tripping a sensor, the completion of
a timer or changes in state of the device. In fact, triggering an event can activate any number of actions,
enabling an automated experience for the user.
Actions: are events you can force to occur in reaction to a trigger enabling a range of possibilities to
automate the user experience.
