Product Overview
The Lightware UMX-TPS-TX140K is a UMX Series HDBaseT transmitter that extends HDMI video, USB KVM data, RS-232, IR, and power over a single CAT cable to compatible HDBaseT receivers. The K suffix designates USB KVM functionality, enabling keyboard, mouse, and USB peripheral extension alongside the video signal — consolidating what would otherwise require separate KVM and AV extender hardware. It operates within Lightware's UMX ecosystem, which supports centralized equipment room installations where displays, cameras, and control interfaces are located far from the source equipment. Integrators specifying HDBaseT transmitter with USB KVM for boardroom or HDMI over HDBaseT with KVM for corporate AV will find this unit appropriate for that architecture.
Product Description
The UMX-TPS-TX140K accepts an HDMI source signal and transmits it alongside USB 2.0 KVM data, bidirectional RS-232, and IR control signals over a single CAT6 or CAT6A cable run at distances up to 100 meters. This eliminates the need for separate USB extension hardware and simplifies cable infrastructure in long-run installations. The transmitter is typically installed at the source device location — at a podium, presenter position, or equipment rack — while the matched receiver is located at the display.

Power over HDBaseT (PoH) capability means the transmitter can receive power from the receiver unit over the same cable, eliminating a local power supply at the transmitter end in many installations. Control system integration is supported via RS-232 and Ethernet, and the unit is compatible with Lightware's LW2 and LW3 protocols. Available from Creation Networks with pre-sales engineering support.
Key Features
- HDBaseT (TPS) Transmission — extends HDMI, USB KVM, RS-232, IR, and power over a single CAT6/6A cable at distances up to 100 meters.
- USB KVM Extension — transmits USB 2.0 keyboard, mouse, and peripheral data alongside video, eliminating a separate KVM extender.
- Power over HDBaseT (PoH) — the transmitter can be powered by the receiver over the same cable, reducing local power supply requirements at the source end.
- Bidirectional RS-232 — passes serial control data in both directions, enabling control system communication with devices at either end of the link.
- IR Extension — extends infrared remote control signals over the HDBaseT link for source device control from the display end.
- UMX Ecosystem Compatibility — designed for use within Lightware's UMX matrix and point-to-point systems, enabling flexible centralized AV architectures.
- HDCP Compliant — supports HDCP-protected content throughout the transmission chain.
- Compact Transmitter Form Factor — small housing suitable for podium, table, or rack installation at the source position.
Typical Applications
- Boardroom
- Conference room

Frequently Asked Questions
- What cable does the UMX-TPS-TX140K require?
- It uses standard CAT6 or CAT6A UTP or STP cable. CAT6A is recommended for the full 100-meter distance. Use shielded cable (STP) in electrically noisy environments.
- Does the transmitter require its own power supply?
- Not necessarily. When paired with a compatible Lightware receiver that supports Power over HDBaseT, the transmitter receives power over the same CAT cable, eliminating the need for a local power outlet at the source position.
- What USB devices can be extended?
- The KVM channel supports USB 2.0 devices including keyboards, mice, webcams, speakerphones, and USB storage devices, subject to USB 2.0 bandwidth limits per device.
- Which receiver should be paired with the TX140K?
- The UMX-TPS-TX140K pairs with Lightware UMX-TPS-RX series receivers within the UMX ecosystem. Consult Creation Networks for the correct receiver SKU for your installation.
- Can it operate within a UMX matrix system?
- Yes. The TX140K is designed for use as a transmitter input card in Lightware UMX matrix frames, in addition to point-to-point deployment with a matched receiver.
- Is the RS-232 passthrough full bidirectional?
- Yes. RS-232 data passes in both directions over the HDBaseT link, enabling a control processor at the rack to communicate with a source device at the podium, or vice versa.
- Where can I purchase the UMX-TPS-TX140K?
