The Stack That Powers Modern Lighting
Implement Sig-Net while preserving Art-Net and sACN interoperability, with LLRP support and documented network behavior for manufacturer technical files.
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.
Sig-Net implementation path
Add authentication and message integrity through a maintained lighting network stack instead of product-by-product retrofits.
Existing protocol continuity
Keep Art-Net and sACN interoperability available for established show-control workflows while introducing Sig-Net where needed.
Technical-file support
Documented protocol behavior gives engineering and compliance teams clearer evidence for CRA technical files and risk assessments.
Lifecycle support story
Maintained protocol updates help manufacturers explain how network behavior is supported through the product lifetime.
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.

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.
