The Universal Fibre Hub (UFH) is a multi-format I/O signal concentrator and data redistribution unit. It is highly flexible and configurable and is suitable for use in a wide range of I/O monitoring and control applications. It has exceptional utility in systems which use a wide variety of different and remote sensors and actuators and which need to be connected to a central node more often than not in difficult electromagnetic environments.

The device can be operated in either Standalone or CompactPCI modes of operation and offers an array of analogue and digital I/Os, UART serial I/O channels, USB Host Interfaces, CAN Interfaces and an ATA Interface.

Architecture

The UFH incorporates two processor domains. Digital and analogue I/O processing are off-loaded to an onboard I/O Processor (16-bit RISC Microcontroller), whilst serial I/O, data communications and other higher level functions are handled by the System Processor (32-bit PowerPC Microprocessor).

The UFH has an onboard 10/100 Mbit/s Ethernet Interface which is configurable for use with either fibre optic or copper media types. The UFH also features an onboard 32-bit 33/66 MHz PMC site, which offers I/O and processing expansion capabilities through the use of a third party PMC adapter. One example of this would be the use of a C²I² Systems Dual Gigabit Ethernet PMC adapter, which provides a dual redundant Gigabit Ethernet link via either fibre optic or copper media.

In typical applications the UFH would be used in the Standalone configuration. However, for applications that require enhanced system connectivity, the UFH is available as a PCI Host Controller. In this configuration it can be connected as System Board to a compatible 32-bit CompactPCI backplane and can manage up to five CompactPCI Peripheral Boards.
