For OEMs · Industrial communication protocols
Your communication protocol — engineered, owned and ready to ship.
For equipment OEMs: we design or reverse-engineer the communication protocols your machines use — CAN, LIN, RS-485, proprietary serial, encoder chains and fiber — then deliver specification, firmware, test harnesses and service tools under NDA. You keep the IP. SAS Middle East FZC delivers from Sharjah across the UAE and GCC. Generic stacks force compromises; a private bus designed for your product line does not.
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.
Fiber & legacy buses
When the protocol is not on a standard datasheet.
Optical links, proprietary serial framing and legacy fieldbuses — captured, decoded and rebuilt into maintainable specifications your firmware team can ship. Encoder families we work with include square wave (TTL RS-422, HTL, Open Collector), analogue 1 Vpp / 11 µA, EnDat 2.1/2.2/2.22, BiSS-C, SSI, SPI, HIPERFACE / HIPERFACE DSL, Tamagawa, Panasonic, Yaskawa, Mitsubishi and Fanuc Serial, plus EtherCAT, PROFINET, EtherNet/IP, CANopen, PROFIBUS, DeviceNet, Modbus RTU/TCP and IO-Link.

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.
Co-engineering
Protocol, firmware and hardware aligned in one UAE workshop.
Your bus specification, embedded stack and connectivity hardware are developed together — so production test, field service and firmware releases stay on one authoritative document.

FAQ
Questions plant engineers ask
Practical answers on OEM protocol engineering — from Sharjah, for plants in the UAE and GCC.
What is OEM protocol work?
For equipment OEMs, SAS designs or reverse-engineers private machine communication buses (CAN, serial, encoder, fiber) so products talk cleanly to PLC, SCADA or a new controller — with specification, firmware, validation and field tools under NDA, delivered from Sharjah for UAE and GCC.
Which OEMs and buses do you cover?
Machine builders and equipment OEMs who need a private or recovered bus: CAN/LIN, RS-485/serial frames, encoder chains and fiber links. Scope is confirmed under NDA from your product roadmap and field constraints.
Does it include hardware?
Often yes: interface boards, gateways and firmware. Protocol without a physical path is not a delivery.
Do you work on site in the UAE and GCC?
Yes. SAS Middle East FZC is based in Hamriyah Free Zone, Sharjah. We survey, engineer and commission OEM protocol engineering on site across the UAE and GCC.
How do we request a technical proposal?
Use Request a technical proposal and include the machine, protocol or fault, and the site. We typically reply within 24 hours.
