For OEMs · Industrial communication protocols
Your communication protocol — engineered, owned and ready to ship.
When we say protocols, we mean communication protocols — the message formats and bus rules your machines use to exchange data. Generic stacks force compromises: bloated frames, licensing risk and field teams that cannot agree on what a byte means. SAS designs your protocol from the wire up — CAN, LIN, RS-485, proprietary serial, encoder chains and fiber links — then delivers the specification, embedded firmware, test harnesses and service tools so every product in your line speaks one language. You keep the IP. We handle the engineering.
Protocol engineering
From bus capture to signed-off specification.
We start with how your machines actually behave on the wire — then document, implement and prove conformance before you commit to a product release. That is the difference between a protocol that works on a demo bench and one that survives years in the field.
Why SAS
Why equipment OEMs choose SAS for communication protocols
You are not buying a software license or a generic gateway config. You are buying a protocol engineering partner that has shipped industrial connectivity products and understands what breaks in production and in the field.
Protocol IP stays yours
Specification, source and manufacturing data are structured for your product releases — not resold as a shared library.
Industrial-grade from day one
Timing, error recovery, EMC-aware physical layers and soak-tested behavior — not hobbyist UART code.
IntelliLink platform leverage
Encoder links, CAN gateways and fiber interfaces from our own product line accelerate development when they fit your architecture.
One language for all teams
Firmware, test engineering, production and field service work from the same document — fewer escalations and faster root-cause analysis.
Typical OEM protocol work
Where your protocol investment shows up on the product.
Illustrative engineering patterns — representative of how we scope protocol projects for machine builders, not a client portfolio.
Machine controller buses
Custom CAN and LIN profiles between your PLC, drives and I/O modules — with deterministic timing and documented fault behavior.
Plant-floor gateways
Translate your proprietary protocol to OPC UA, MQTT or standard CAN for integrators — without exposing your frame internals.
Validation before release
Capture/replay, conformance scripts and acceptance criteria signed off before your production line depends on the stack.
Engineering scope
Full-stack communication protocol engineering
Everything required to put a proprietary or OEM-specific bus into series production — not a slide deck and a reference driver.
Communication protocol specification
Frame layout, timing, CRC rules, state machines, error handling and versioning policy — the single reference your teams share.
Embedded implementation
Firmware on MCU, FPGA or IntelliLink platforms; drivers, stacks and gateway translation to standard buses where needed.
Validation & simulation
Bus capture/replay, conformance scripts, soak tests and documented acceptance criteria before you ship product.
NDA & IP boundaries
Clear ownership of your protocol IP, manufacturing data and field tools — structured for OEM product releases.
Gateway & tooling
PC configurators, service interfaces and plant-floor gateways so integrators work with your protocol without exposing internals.
Legacy recovery
When documentation is missing, we characterize existing buses and reproduce behavior — see also Reverse Engineering.
Project workflow
How an OEM protocol project runs
Milestone-based, NDA-protected — scoped to your release gate, not an open-ended integrator engagement.
1. Discovery & bus characterization
Review existing equipment, documentation gaps and target volumes. Capture live traffic where needed.
2. Specification & architecture
Frame layout, state machines, versioning, CRC rules and interface contracts — agreed before firmware starts.
3. Implementation & bench validation
Firmware on MCU, FPGA or IntelliLink hardware; drivers, gateways and simulation harnesses.
4. Production & field handover
Test scripts, configurators, service interfaces and documentation for your release process.
