Communication & Protocols
Robust industrial and automotive communication stacks. We build bus interfaces capable of sustaining communication integrity through industrial electromagnetic noise over kilometre-long cable runs.
Core Engineering Principles
Deterministic Fieldbus Bus Access
Prioritised arbitration protocols ensuring critical safety and trip signals preempt general status telemetry.
Multi-Drop 2-Wire AU999 Protocol
Proprietary daisy-chained 2-wire protocol delivering both DC power and half-duplex digital communication on one unshielded pair.
CAN-FD High-Throughput Diagnostics
Automotive grade 5 Mbps CAN Flexible Data-rate interfaces for vehicle telemetry and rapid firmware flashing.
System Architecture Flow
End-to-end signal processing and control path engineered for Communication & Protocols.
Physical Layer Isolation
Differential RS-485 / CAN transceivers with 2.5kV galvanic isolation.
Hardware CRC Verification
Hardware-accelerated packet cyclic redundancy check eliminating corrupted frames.
Queue Buffer Management
Ring-buffered DMA transfers preventing buffer overruns under 100% bus utilization.
Supervisory Gateway Bridging
Low-latency protocol translation to Ethernet TCP/IP and BACnet.
