Product Short Description
Product Description
The TPMC815-11 is a high-performance, single-width 32-bit PMC (PCI Mezzanine Card) module designed to deliver a complete ARCNET communication interface for industrial embedded systems. Engineered for reliability in harsh environments, it integrates the COM20020 ARCNET controller with a traditional isolated hybrid physical layer, ensuring robust data exchange across industrial networks. It serves as a critical communication bridge between PMC-compatible host systems and ARCNET-based field devices.

Functional Overview
The TPMC815-11 functions as a dedicated ARCNET communication co-processor for PMC-compatible host systems. It receives data from the host’s PMC bus, processes it via the COM20020 controller, and transmits it over the isolated ARCNET hybrid interface. Conversely, it receives ARCNET data, converts it to PMC bus-compatible signals, and forwards it to the host. The electrical isolation safeguards the host from network-side noise and faults, while the wide temperature range ensures stable operation in harsh industrial settings. By enabling seamless ARCNET connectivity, it extends the lifespan and functionality of legacy industrial networks and embedded control systems.
