DL-SC41U-TX Quick Guide

The DigitaLinx DL-SC41U-TX is a 4x1 mul format A/V presentaon auto switcher that supports video
resoluons up to 4K@60Hz 4:4:4 8bit deep color, is HDCP 2.2 compliant and has a built in USB 3.0
switching hub for control and integraon of USB devices such as USB cameras and microphones. The
switcher features four video inputs; (2) HDMI, (1) Display Port and (1) USB-C. The USB-C input supports
video, data (USB host) and power charging up to 40w. There is a 2 port USB client hub built with 2 USB
host ports that can be switched independently or can be assigned to follow a video input so when the
video input is triggered or switched, the dened USB host port will also switch. The switcher features
two matrix outputs; HDMI and HDBaseT 2.0. The built in HDBaseT 2.0 transmier output supports long
distance transport of audio, video and High Speed USB 2.0 signals up to 190Mbps up to 70 meters /
232’ using one category cable. The switcher is compable with the DL-SCU-RX HDBaseT 2.0 receiver
(sold separately) and the receiver can supply power to the DL-SC41U-TX remotely when used in this
conguraon.
The DL-SC41U-TX gives you the ability to automate the display power ON by using pre-loaded RS232
commands whenever a video signal is introduced to the system using any A/V input. It will also turn
the display power OFF aer a specied amount of me has passed when no video signal or switching
acvity is present. For a complete list of programming commands to automate display power status,
please see the complete owners manual online at www.libav.com or by using the QR code on the print
page of this guide.
The DL-SC41U-TX can be controlled via front panel buons or by API commands using RS232 or
Ethernet. A web server / GUI is built in that features A/V and USB switching control, automac display
control and input EDID management.
The DL-SC41U-TX is ideal for soware based video teleconference rooms that require the consolidaon
and sync of A/V and USB signals from a laptop or room PC.
NOTE: The DL-SC41U-TX switcher can be used as a standalone switcher or paired with an HDBaseT
receiver. The DL-SCU-RX HDBaseT 2.0 receiver (sold separately) is required to complete an extension
circuit. When using the DL-SCU-RX, only USB 2.0 Full Speed devices can be used on the receiver.

Connecvity Instrucons
1. Verify all components included with the extender set are present before installaon.
2. Turn o power and disconnect the audio/video equipment by following the manufacturer’s
instrucons.
3. Connect a source device to the HDMI inputs using an HDMI cable that is less than or equal to 5
meters in length. For source devices that are further away, an HDMI extension device will be required
to complete the connecon.
4. Connect a source device to the Display Port input using a Display Port cable that is less than or
equal to 5 meters in length. For source devices that are further away, an extension device will be
required to complete the connecon.
5. Connect a source device to the USB-C input using a USB-C video cable that is less than or equal to 2
meters in total length. Only a USB-C cable rated for video, data and power will work as charging cables
typically will not support video and/or data.
6. Connect an HDMI cable that is less to or equal to 5 meters in length between the display and the
HDMI output of the DL-SC41U-TX. For display devices that are further away, an HDMI extension device
will be required to complete the connecon such as the DL-SCR-RX HDBaseT 2.0 receiver.
7. (Oponal) Connect Category 6 or greater solid core twisted pair cable with RJ45 connectors
between the DL-SC41U-TX and a compable HDBaseT 2.0 receiver (DL-SCU-RX sold separately). TIA/
EIA-568B straight-through wiring connecons must be used.
8. (Oponal) Connect an HDMI cable less to or equal to 5 meters in length between the TV display and
the HDBaseT 2.0 receiver (DL-SCU-RX sold separately) HDMI output.
9. If using the DL-SC41U-TX in standalone mode, connect the power supply adapter to the DL-SC41U-
TX. If using the oponal HDBaseT receiver (DL-SCU-RX, sold separately) to power the DL-SC41UI-TX via
HDBaseT, connect the power supply adapter to the DL-SCU-RX.
NOTE: If you choose to supply 40 was of power charging to the USB-C input on the DL-SC41U-TX
while using the DL-SCU-RX extender receiver, you will need to power both the DL-SC4U-TX and the
DL-SCU-RX devices with the supplied power supplies.
10. (Oponal) Connect RS232 / Ethernet control to a 3rd party control system to control switcher
funcons
NOTE: A list of RS232 commands for this unit is available in the owners manual online at
www.libav.com under the DOCUMENTATION tab of the DL-SC41U-TXproduct page
11. Power on aached audio/video devices.

Cabling Wiring Requirements
Twisted Pair Wiring
Use TIA/EIA-568B wiring for Category 6
connecon between send and receive
units.
HDBaseT Cabling
To ensure proper performance of the DL-SC41U-TX, it is recommended that you use solid
core, shielded Category 6 F/UTP cabling at a minimum. Category 5e F/UTP may perform
well but may not support power over HDBaseT reliably over longer distances.
For opmized HDBaseT performance use the following Liberty Wire and Cable branded
cabling;
Category 6 plenum; 24-4P-P-L6SH
Category 6A plenum; 24-4P-P-L6ASH
Category 6 NON-plenum; 24-4P-L6SH
Category 6A NON -plenum; 24-4P-L6ASH
When using shielded category cabling ALWAYS ...
....use shielded connectors
....properly ground the category cable
The RS232 connecon on the matrix is 3 pin
phoenix. See below for RS232 conguraon.
• 9600 baud
• 8 Data Bits
