Key Features

1. Highly Reliable ARCNET Communication
   • Implements the robust ARCNET industrial protocol with a 2.5 Mbps transfer rate for deterministic, real-time data exchange.
   • Supports multiple network topologies (star, bus, ring) for flexible system design.
2. Isolated & Rugged Electrical Design
   • Provides 250V RMS electrical isolation between the host system and the ARCNET network, protecting against EMI and ground loops.
   • Industrial-grade components ensure stable operation in extreme temperatures (-40°C to +85°C) and high-vibration environments.
3. Flexible Media Interface
   • The TPMC815-11 model offers a traditional isolated hybrid interface, supporting both fiber-optic and twisted-pair cabling for maximum installation flexibility.
4. Standard PMC Form Factor
   • Compliant with the PCI 2.1 standard, enabling seamless integration into a wide range of embedded systems, PLCs, and industrial computers with PMC slots.
   • Hot-swappable capability allows for maintenance without system shutdown.
5. Broad OS Support & Diagnostics
   • Compatible with major real-time and general-purpose operating systems.
   • Features on-board LEDs for real-time status monitoring (power, link, activity) and supports remote diagnostics.
