Frequently Asked Questions - DUX-SCL AMX

How do I connect the DUX-SCL to my AV system?

Connect the Ethernet cable to your network switch and the RS-232 cable to your AV controller. Ensure the power supply is connected.

Can I use the DUX-SCL as a standalone controller?

Yes, the DUX-SCL can operate as a standalone touch panel for basic AV control, but advanced features require integration with an AMX system.

How do I reset the DUX-SCL to factory defaults?

Press and hold the reset button on the back for 10 seconds until the screen flashes. Release to restore factory settings.

What is the IP address of the DUX-SCL?

By default, the device uses DHCP. You can check the IP address in the Network Settings menu on the touch panel.

Can I customize the interface buttons?

Yes, using AMX Design Xpress software, you can create custom button layouts and assign macros.

Why is my touch screen not responding?

First, check the power supply. If the screen is on but not responding, perform a soft reset by cycling power. If the issue persists, contact support.

What is the maximum cable length for RS-232?

For reliable communication, use RS-232 cable up to 50 feet (15 meters). Longer runs may require a signal booster.

Can I mount the DUX-SCL on a wall?

Yes, the device includes a wall mount bracket. Ensure the mounting surface is flat and secure with the provided screws.

How do I update the firmware?

Download the latest firmware from the AMX website. Connect via Ethernet and use the device's web interface to upload the file.

INTRODUCTIONS

DUX-SCL is an HDMI Scaler allowing users to match native resolutions of their displays and is designed to use with standard displays, HDMI Matrix switchers, etc., where HDMI is used.

DUX-SCL accepts input resolutions from 800 x 600 to 1920 x 1200 (VESA) and 480p to 2160p (SMPTE) and supports output resolution 1280 x 768, 1280 x 800, 1920 x 1200, 3840 x 2160 and Auto Scaler (VESA) and 1280 x 720P, 1920 x 1080P (SMPTE). Such variety of output resolution options provide users more freedom while adjusting their video signal for the best result.

DUX-SCL installs a SCALER switch for manual adjustment of output resolutions. When connected to a control PC through RS232, the device can be controlled through API command.

DUX-SCL is ideal for applications where high quality video scaling or 4K-1080P down-scaling is required due to the mix use of displays in different aspect ratio or preferred timing. Seamless switching is realizable while DUX-SCL is working with DUX-8C or DUX-8D HDMI Matrix.

Features

• HDMI Input and Output both support up to 4K@60Hz 4:4:4 8bit.
• HDCP 2.2 compliant.
● Supports scaling output adjustment by SCALER DIP switch.
- Seamless switching when using with DUX-8C or DUX-8D Matrix.
