Rugged, Small, Lightweight, Ethernet, FPGA-Based Multi-Function I/O Controller

The ATC-ETH-DIG-I/O is an Ethernet based Multi-Function I/O module that employs dual Altera Cyclone® FPGAs for maximum deterministic performance and I/O capability.The module provides an Ethernet network interface for Digital I/O, Analog and Serial communication. Although it is fully functional as delivered, the User FPGA can be modified for custom bus implementations, which allows maximum flexibility and pre-processing capability for time-sensitive applications.To communicate with the host, the ATC-ETH-DIG-I/O uses simple standard networking protocol – Modbus – that allows for control and data transfers.

The Eth-ReporterII uses a single 160 pin I/O connector for all system inputs and outputs. The I/O connector is a high density D-type connector with female pins. The mating cable end connector is available in a number of configurations to meet specific application requirements.
