Hardware Architecture and Energy Storage

The board contains over fifty-five integrated circuits for signal processing. You will find EPROM chips for permanent data storage. FPGA components handle the complex logic control tasks. The design includes a dedicated power fail detection circuit. This circuit controls two relays to protect the network. It disconnects the unit from DLAN+ during a power loss.

Interface and Connectivity

This module connects external wiring through the 1TB terminal board. A direct RS-232C port enables local programming. For expansion, the board integrates an optional Genius LAN controller. It also uses a coaxial BNC connection for high-speed ARCNET.
