How to use

To use the Kramer SWT3-21-HU-TR, first determine if the unit will function as a transmitter or a receiver and configure it accordingly during power-up. Connect your video sources, such as a laptop via USB-C or an HDMI device, to the appropriate input ports. Connect your display or projector to the output side. For extended setups, use a high-quality twisted pair cable to link the HDBaseT ports. Once connected, the auto-switching feature will detect active signals and route them to the display automatically. You can manage settings, firmware updates, and signal routing via the embedded web interface or local control buttons.

What to consider before purchase

• Ensure your infrastructure supports HDBaseT 3.0 for optimal performance.
• Verify that your USB-C devices support DP-Alt-Mode for video output.
• Check the power requirements and available space for the 190mm x 116mm x 27mm unit.
• Confirm the compatibility of your existing control systems with the unit's IP, RS-232, or IR interfaces.

Usage recommendations

For the best performance and maximum extension reach, always use high-quality, shielded twisted pair cables as recommended by Kramer. Ensure that the unit is placed in a well-ventilated area to maintain optimal operating temperatures during extended use.
