Lightware UCX-4x3-TPX-TX20 – USB-C HDMI Matrix Switcher Transmitter for TPX HDBaseT

Product Overview

The Lightware UCX-4x3-TPX-TX20 is a USB Type-C and HDMI 2.0 matrix switcher transmitter that combines the Taurus UCX BYOD collaboration platform with a Taurus TPX HDBaseT output, enabling AV extension over structured cabling to TPX-compatible receivers. The device accepts 4 inputs (2x HDMI 2.0, 2x USB-C) and switches selected video, audio, USB, and control signals to a local HDMI 2.0 output and simultaneously to the TPX HDBaseT output, distributing content to one or more display endpoints over CAT cabling. AV integrators specifying a Lightware UCX USB-C matrix switcher with HDBaseT output for conference rooms, training rooms, or boardrooms with CAT-based AV distribution infrastructure will find the UCX-4x3-TPX-TX20 a precise fit.

Product Description

The UCX-4x3-TPX-TX20 is part of Lightware's Taurus UCX product family, integrating the full UCX USB-C switching and USB peripheral management capability with a TPX HDBaseT transmitter output. This makes it suitable for installations where structured CAT cabling serves as the distribution medium and SDVoE/10G networking is not required or available.

The two HDMI 2.0 inputs accept room-installed sources such as room PCs, video codecs, or media players. The two USB-C inputs handle laptop or mobile device connections with simultaneous 4K video, audio, USB 2.0 data, and up to 100W power delivery over a single cable. The device selects from these inputs and transmits the result to the local HDMI output and the TPX HDBaseT link to connected receivers.

USB 2.0 peripheral switching supports cameras, speakerphones, and HID devices connected to USB-A ports, routed independently from video between active hosts. Control options include RS-232, GPIO, Ethernet, and OCS. The device supports 5K (5120x2160) at 30Hz 4:4:4 or 60Hz 4:2:0 via HDMI 2.0. Remote Syslog supports SIEM integration.

Key Features

• USB-C Input with 100W Power Delivery — Two USB-C inputs each supply up to 100W laptop charging while simultaneously transmitting 4K video, audio, and USB 2.0 data over a single cable.
• TPX HDBaseT Transmitter Output — Transmits selected AV signals over CAT5e/6/7 structured cabling to TPX-compatible receivers, avoiding the need for 10G networking infrastructure.
• 4-Input Matrix Switching — Routes 2x HDMI 2.0 and 2x USB-C inputs to a local HDMI output and the TPX HDBaseT link simultaneously.
• 5K Resolution Support — Accepts 5120x2160 at 30Hz 4:4:4 or 60Hz 4:2:0 from HDMI 2.0 sources for ultrawide display deployments.
• Independent USB 2.0 Switching Layer — Routes cameras, speakerphones, and USB-HID peripherals between hosts independently from video switching.
• Taurus TPX Ecosystem Compatibility — Operates as a transmitter endpoint within Lightware's TPX AV distribution ecosystem, compatible with TPX receiver variants and MX2M matrix integration.
• Remote Syslog — Forwards device events to external SIEM systems via TCP, UDP, or TLS (RFC3164 / RFC5424).
• Pixel Accurate Reclocking — 0-frame video delay on all input paths with signal integrity management.
• HDCP 1.4 and 2.2 — Full HDCP compliance on all input and output paths.

Frequently Asked Questions

What is the difference between the UCX-4x3-TPX-TX20 and UCX-4x3-TPN-TX20?

The TPX-TX20 distributes AV signals over HDBaseT via CAT structured cabling to TPX-compatible receivers. The TPN-TX20 distributes over 10G Ethernet using SDVoE technology to TPN IP-based receivers. The TPX variant is the right choice for CAT-cabled buildings without 10G networking; the TPN variant suits IP-based AV over IP infrastructure.

Does the USB-C input charge a connected laptop during a meeting?

Yes. Each USB-C input supports up to 100W power delivery, maintaining laptop battery charge throughout the meeting without requiring a separate wall adapter at the table.

Can the UCX-4x3-TPX-TX20 work with Lightware MX2M matrices?

Yes. The UCX-4x3-TPX-TX20 can operate as an input endpoint within a Lightware MX2M-based system via the TPX card (MX2M-4TPX-IB), enabling the UCX's source selection and USB switching to feed the larger matrix.

What USB peripherals can be connected to the device?

The four USB-A device ports support cameras, speakerphones, touch displays, USB-HID controllers, and other USB 2.0 peripherals. These are routed independently from video to whichever USB-C or USB-B host is active.

Is remote management and logging supported?

Yes. The device supports remote Syslog via TCP, UDP, or TLS (RFC3164 and RFC5424), enabling integration with enterprise SIEM and network monitoring platforms for centralized device event logging.

Where can I purchase the Lightware UCX-4x3-TPX-TX20?

The UCX-4x3-TPX-TX20 is available at Creation Networks, an authorized Lightware reseller for commercial AV projects.
