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.

IntelliLink experience

Competitive moatA proprietary bus is harder to copy than a mechanical feature — and it keeps integrators on your ecosystem.
Fewer field failuresOne authoritative spec means firmware, production test and service tools stay aligned across releases.
Faster series launchReuse validated IntelliLink building blocks instead of debugging a generic stack under deadline pressure.
NDA-first deliveryMilestone-based engagements with clear IP boundaries — structured for OEM product roadmaps.

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.

Embedded firmware development and protocol stack bring-up on industrial PCB

Machine controller buses

Custom CAN and LIN profiles between your PLC, drives and I/O modules — with deterministic timing and documented fault behavior.

Industrial CAN gateway installed in control cabinet for OEM equipment

Plant-floor gateways

Translate your proprietary protocol to OPC UA, MQTT or standard CAN for integrators — without exposing your frame internals.

Protocol validation with oscilloscope and bus analysis on industrial equipment

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.
