Crestron HD-TX-301-C-E – DM Lite 3×1 Auto-Switcher Transmitter, HDMI and VGA over CATx

Product Overview

The Crestron HD-TX-301-C-E is a surface-mount DM Lite 3×1 auto-switcher transmitter that accepts HDMI, VGA, and analog audio inputs and extends the active source signal to a paired DM Lite receiver or DMPS Lite presentation switcher over a single Cat5e or Cat6 CATx cable run. Designed for podium, credenza, and tabletop installation at the presenter position in conference rooms, training rooms, and classrooms, it auto-switches to the active connected source — eliminating manual input selection for laptop and device presenters. The HD-TX-301-C-E is the presenter-end component for DM Lite-based commercial AV systems, replacing long HDMI cable runs to the display with structured CATx wiring for reliable commercial-grade signal distribution.

Product Description

In commercial AV installations, running HDMI directly from a presenter table or podium to a wall-mounted display creates cable length and signal reliability challenges that increase with room size. The DM Lite CATx extension architecture solves this by running a single Cat5e or Cat6 structured cable from the presenter location to the display or distribution point, with the HD-TX-301-C-E providing the presenter-end connection and signal conversion. The three-input auto-switcher function handles the reality of mixed presenter device environments: HDMI from current laptops, VGA from legacy equipment, and analog audio for devices with headphone-only audio output are all accommodated without the presenter having to select an input manually. The auto-detection logic switches to whichever input becomes active, making the system transparent and reliable for non-technical users. Surface mount form factor allows installation directly on a podium surface, inside a credenza, or in a tabletop cutout, keeping presenter connections accessible and professional. Compatibility with the DMPS Lite family of integrated presentation switchers makes the HD-TX-301-C-E a component in a broader Crestron AV system architecture that can include display control, room routing, and automation. Refer to the Crestron data sheet for full specifications including maximum cable run distances, power requirements, and video resolution support.

Key Features

• 3×1 Auto-Switching: Automatically detects and switches to the active connected source among three inputs — no manual input selection required from presenters in conference rooms, training rooms, and classrooms.
• HDMI, VGA, and Analog Audio Inputs: Accepts HDMI from current laptops and media players, VGA from legacy presentation devices, and analog audio for devices without digital audio output — accommodates mixed presenter device environments without requiring dongles or adapters at the podium.
• DM Lite Signal Extension over CATx: Transmits AV signals over standard Cat5e or Cat6 structured cabling to a compatible DM Lite receiver or DMPS Lite system — replaces long HDMI runs with commercial-grade structured cabling for reliable, distance-capable presenter signal extension.
• Surface-Mount Tabletop Form Factor: Compact chassis designed for podium surface, credenza top, or tabletop cutout installation at the presenter location — keeps presenter connections accessible and professional without cable clutter to the display.
• DMPS Lite System Compatible: Serves as the presenter-end transmitter in DM Lite and DMPS Lite commercial AV systems — integrates into the broader Crestron presentation switcher architecture including display control, room routing, and room automation.
• Commercial-Grade Signal Transport: DM Lite CATx signaling provides the reliability required for commercial AV installations in terms of HDCP handling, signal conditioning, and compatibility with Crestron receiver infrastructure. Refer to Crestron data sheet for full specifications.

Typical Applications

• Conference rooms with podium or credenza presenter connections requiring CATx signal extension to wall-mounted displays over structured building cabling
• Training rooms and classrooms with instructor station HDMI and VGA inputs extended to front-of-room displays without long HDMI cable runs
• Huddle rooms and small meeting spaces with DMPS Lite-based presentation switcher deployments requiring a tabletop presenter input point
• University and K-12 lecture rooms with mixed presenter device environments including current laptops (HDMI) and legacy equipment (VGA)
• Government and corporate conference rooms being upgraded from long HDMI infrastructure to structured CATx AV distribution
• Multi-purpose rooms with movable podiums requiring CATx signal extension from the presenter position to a fixed display location
• Boardrooms with credenza installations where presenter connections are embedded in furniture and extended via building CATx infrastructure

Frequently Asked Questions

What receiver or switcher does the HD-TX-301-C-E pair with?
The HD-TX-301-C-E pairs with Crestron DM Lite receivers and DMPS Lite presentation switchers that accept a DM Lite CATx input. Contact Creation Networks to confirm compatible receiver models for your specific installation design.

What CATx cable type and maximum run length is supported?
Standard Cat5e or Cat6 UTP is compatible. Maximum cable run length depends on the paired DM Lite receiver or DMPS Lite model — refer to the Crestron data sheet for the specific receiver or contact Creation Networks for maximum distance specifications before designing cable infrastructure.

Does the HD-TX-301-C-E require a Crestron control processor?
No — auto-switching operates independently without a Crestron 4-Series control processor. The device automatically detects and switches to the active source. A control processor is not required for basic auto-switch and signal extension operation, though many installations pair this transmitter with a DMPS Lite switcher that includes integrated control functions.

Is this transmitter compatible with 4K sources?
The HD-TX-301-C-E is a DM Lite product designed for HD signal extension. For 4K60 signal requirements, refer to Crestron’s DM or DM NVX 4K-capable product lines. Contact Creation Networks for 4K AV system design guidance if your installation requires 4K resolution.

Can the auto-switching behavior be overridden manually?
Auto-switching behavior and any manual override capabilities are detailed in the Crestron data sheet. Contact Creation Networks for configuration guidance if your installation requires specific input priority or manual switching control.

What is the warranty on the Crestron HD-TX-301-C-E?
Crestron provides a standard 3-year limited warranty. Contact Creation Networks for warranty service details and Crestron True Blue Support options.
