FireWire is a registered trademark of Apple Computer, Inc.
	FOUNDATION Fieldbus		The FOUNDATION fieldbus is a serial, all-digital, two-way communication system that serves as a local area network (LAN) for factory instrumentation and control devices. It uses a line or tree topology and distributed data transfer (DDT). In the hierarchy of digital networks, the FOUNDATION fieldbus is on the lower end.
	GPIB		The general-purpose interface bus (GPIB) is designed to connect computers, peripherals and laboratory instruments so that data and control information can pass between them. It was originally developed by Hewlett Packard (HP) and called the HPIB bus. GPIB is also know as the IEEE 488 bus, and is electrically equivalent to the IEC 625 bus.
