Communication Interface

	Communication Interface
	Your choices are...
	USB		Universal serial bus (USB) is a 4-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. The USB design is standardized by the USB Implementers Forum (USBIF), an organization that includes leading companies from the computer and electronics industries. The current USB specification is USB 2.0, which supports data transfer rates of up to 480 Mbps.
	IEEE 1394 (FireWire®)		IEEE 1394 or FireWire® is an interface standard adopted by the Institute of Electrical and Electronics Engineers (IEEE) for very fast digital data transfers such as streaming video. IEEE 1394 connectors are used to transmit and receive data among FireWire devices, and are designed to replace external high-speed peripheral connections to personal computers, including hard disks, CD-ROMs, DVDs, graphics cards, high-speed scanners, direct video, monitors, etc. Tiny, robust FireWire connectors will also become important parts of home entertainment, communication, and appliance networks. FireWire is a registered trademark of Apple Computer, Inc.
	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 known as the IEEE 488 bus, and is electrically equivalent to the IEC 625 bus.
	SCSI		Small computer systems interface (SCSI) is an intelligent I/O parallel peripheral bus with a standard, device-independent protocol that allows many peripheral devices to be connected to the SCSI port. A single SCSI bus can drive up to eight devices or units: the host adapter or controller, and seven other devices. Each device is assigned a different SCSI ID, ranging from 0 to 7.  SCSI formats include SCSI-1, SCSI-2, SCSI-3, Wide SCSI, Fast SCSI, Wide Fast SCSI, Ultra SCSI, Ultra2 SCSI, Ultra3 SCI (Ultra160), Ultra 320 SCSI, and Ultra640 SCSI.
	TTL		Transistor-transistor logic (TTL) is a common type of digital circuit in which the output is derived from two transistors. More commonly, however, TTL is used to designate any type of digital input or device.

To handle simultaneous demands, Ethernet uses carrier sense multiple access/collision detection (CSMA/CD) to monitor network traffic.
	Modem		Modems (modulator-demodulators) are devices or programs that enable a computer to transmit data over telephone lines. Computer information is stored digitally, whereas information transmitted over telephone lines is sent in the form of analog waves. A modem converts between these two forms.

Device Specifications

	Analog Input Channels:		This is the maximum number of analog channel inputs. The single-ended number is specified when single-ended inputs are available as twice the number of differential inputs. Differential channels use the difference between two signals as an input; common mode is filtered out. In some systems, differential inputs are combinations of two single-ended inputs. When this is the case, twice the number of differential channels are available as single-ended inputs.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Differential Channels		Differential channels have two inputs. The signal to process is the voltage (V) difference between the two inputs. For example, if one reading is 4.93 V and the other reading is 5.16 V, the meaningful value is the 0.23 V difference between the two. Often, this applies to precision measurements where the difference between two low-voltage inputs is small but critical.
