QubiCore: Sig-Net-ready Lighting Network Stack for CRA-era Products

Why QubiCore now?

QubiCore is a modern C++ software library designed to simplify lighting network integration for fixture manufacturers, control equipment developers, and OEMs. Built for reliability and performance, QubiCore delivers complete, standards-compliant implementations of Sig-Net, Art-Net 4, sACN, and LLRP, eliminating the need for manufacturers to develop and maintain their own protocol stacks.

A practical Sig-Net path for existing lighting products

QubiCore helps manufacturers add authenticated and integrity-protected lighting networking while keeping Art-Net and sACN interoperability in place. LLRP support preserves low-level discovery and configuration workflows without making a broad protocol migration the product strategy.

QubiCore does not make a product CRA compliant by itself. It provides a CRA-ready implementation path and documentation inputs that can support a defensible technical file, but each manufacturer still needs a product-specific assessment, vulnerability process, and conformity evidence.

Why manufacturers are revisiting network stacks

Trusted-network assumptions

Art-Net and sACN workflows remain important, but CRA-era products need a clearer answer for authentication, integrity, and unauthorized control traffic.

Fragmented retrofit risk

Adding Sig-Net product by product can create inconsistent network behavior that is harder to test, document, and maintain.

Interoperability pressure

Manufacturers still need Art-Net and sACN continuity for existing show-control workflows while introducing stronger network behavior where the threat model requires it.

Technical-file evidence gap

CRA technical files need documented design decisions, protocol behavior, update expectations, and product-specific risk assessment inputs.

How QubiCore Solves These Challenges

Sig-Net without a one-off retrofit

Add authenticated, integrity-protected lighting communication through a maintained stack instead of stitching security onto each product line separately.

Art-Net and sACN continuity

Keep existing controller, fixture, and gateway workflows practical while adding a Sig-Net path for products that need stronger network behavior.

LLRP discovery and configuration

Support low-level discovery and configuration workflows through LLRP.

Documentation for CRA technical files

Use documented protocol behavior and integration notes as input to technical files and product-specific risk assessments.

Maintained lifecycle support

Protocol updates and support help manufacturers explain how network behavior is maintained during the product support period.

Reduced implementation effort

Use a maintained stack to reduce the engineering time spent building, testing, and documenting protocol behavior from scratch.

Why use QubiCore for Sig-Net adoption?

Avoid fragmented Sig-Net retrofits

Give product teams one maintained implementation path instead of separate authentication and integrity patches per device family.

Preserve existing show-control workflows

Keep Art-Net and sACN interoperability visible while adding Sig-Net for products and deployments that need it.

Maintain one networking layer

Reduce duplicated protocol code across fixtures, gateways, controllers, and OEM variants.

Support the compliance documentation story

Use maintained and documented behavior as stronger input for CRA technical files and product-specific assessments.

Frequently Asked Questions

Everything you need to know about QubiCore

QubiCore supports Sig-Net, Art-Net 4, sACN (ANSI E1.31), LLRP, and custom protocol support for product-specific workflows.

No software library can guarantee product-level CRA compliance by itself. QubiCore provides a CRA-ready foundation for lighting networking and can support a defensible technical file, but each manufacturer still needs a product-specific risk assessment, documentation, vulnerability handling, and conformity process.

Sig-Net adds authentication and message integrity to lighting network communication. Those controls help address CRA expectations around secure design, protocol risk assessment, and protection against unauthorized control traffic.

Yes. QubiCore is designed to preserve Art-Net and sACN interoperability while giving manufacturers a path to add Sig-Net where authentication and integrity are required by the product threat model.

QubiCore implements LLRP, the useful low-level discovery and configuration part from the RDMnet family. We do not position full RDMnet as a core QubiCore protocol.

QubiCore is cross-platform and runs on Windows, Linux, macOS, RTOS, and bare metal systems. It supports ARM Cortex (STM32, Raspberry Pi, Nordic nRF), x86/x86_64, and Xtensa (ESP32) architectures.

QubiCore is licensed to manufacturers and OEMs on a per-product basis. Contact us for licensing details tailored to your integration needs.

QubiCore includes our Always-On-Top Guarantee: when ANSI, ESTA, or protocol organizations release updates, we implement them and provide updates to licensees. You stay current without dedicating engineering resources.

Yes. QubiCore offers heap-free configurations optimized for embedded systems with limited memory, as well as heap-enabled configurations for more powerful devices. It's modular, so you can include only the features you need.

Most manufacturers integrate QubiCore in days to weeks, depending on product complexity—significantly faster than the months required for in-house protocol development.

Yes. All QubiCore licensees receive direct technical support from our lighting protocol specialists, including integration assistance and troubleshooting.

QubiCore keeps Art-Net and sACN behavior aligned with established lighting workflows while adding Sig-Net and LLRP support where they fit the product architecture.

Absolutely. QubiCore is designed to be customizable and can be configured to fit your product's exact requirements without unnecessary complexity.

Yes. QubiCore is thoroughly tested and already deployed in real-world lighting installations. It's production-ready and backed by our engineering expertise.
