APPENDIX F - GLOSSARY199EATON PXG200E User Manual • IM02603001E Rev 5, 11-May-2012 • Firmware Version 5.03:3835Appendix F GlossaryAccess Control: An important security feature that limits access to ModbusTCP, INCOM Passthrough and SNMP to Trusted Hosts. It has functions thatare similar to a security firewall.AWG (M) American Wire Gauge: Standard wire cross-section areaBACnet/IP: A communications protocol that provides read-only data fromBuilding Automation Systems (BASs), so that the PXG200E can be easilyintegrated in a BAS alongside other BACnet/IP-capable devices.Baud Rate: A measure of the symbol rate; that is, the number of distinctsymbol changes (signalling events) made to the transmission medium persecond in a digitally modulated signal.Bus: A Bus represents a group of devices. It will often be used to indicate agroup of electrical monitoring devices connected to the same power Bus.Coordinated Universal Time: See UTC.CSV file format: A comma delimited format where each record is a singleline and each field in the record is indicated by a comma.Device: A device is the actual communicating unit that is connected to one ofthe downstream communications ports of the PXG200E.DHCP: DHCP (Dynamic Host Configuration Protocol) is a set of rules used bycommunications devices such as a computer, router or network adapter toallow the device to request and obtain an IP address from a server which hasa list of addresses available for assignment.DIN Rail Mounting: DIN is short for Deutsches Insitut für Normung eV, thestandards setting organization for Germany. A DIN rail is a mounting rail thatconforms to one of the standards defined by DIN. The Ethernet Switch maybe mounted using a DIN rail.DNS IP Address: Location of server that provides mapping of names to IPaddresses. It is a configuration setting that is provided by the IT manager.DNS Server: On the Internet, the Domain Name System (DNS) stores andassociates many types of information with domain names; mostimportantly, it translates domain names (computer hostnames) to IPaddresses. It also lists mail exchange servers accepting e-mail for eachdomain. In providing a worldwide keyword-based redirection service, DNSis an essential component of contemporary Internet use.EDS (Electronic Data Sheet): A worksheet that defines supported dataparameters for a specific device.Ethernet: Ethernet is a large, diverse family of frame-based computernetworking technologies that operates at many speeds for Local AreaNetworks (LANs). The name comes from the physical concept of the ether. Itdefines a number of wiring and signaling standards for the physical layer,through means of network access at the Media Access Control (MAC)/DataLink Layer, and a common addressing format (Ethernet and Timing).
