Browser
Short for Web browser, a software application used to locate and display Web pages. The two most popular browsers are Microsoft Internet Explorer and Firefox. Both of these are graphical
browsers, meaning that they can display graphics as well as text. In addition, most modern browsers can present multimedia information, including sound and video, though they require plug-
ins for some formats.
CAN Bus
Controller Area Network (CAN or CAN bus) is a serial protocol utilized for communication between Eltek Valere ’s rectifiers, controllers and other control units. The protocol is used in DC
power systems that use the Smartpack controller, the Compack controller and in Aeon systems.
The CAN bus standard was originally designed to allow microcontrollers and devices to communicate with each other without a host computer.
The CAN specification defines the Data Link Layer, while ISO 11898 defines the Physical Layer.
The CAN bus is a 2-wire interface running over either a Shielded Twisted Pair (STP), Un-shielded Twisted Pair (UTP), or Ribbon cable. Each node uses a Male 9-pin D connector.
Crossover cable
An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly where they would normally be connected via a network switch, hub or router,
such as directly connecting two personal computers via their network adapters.
The 10BASE-T and 100BASE-TX Ethernet standards use one wire pair for transmission in each direction. The Tx+ line from each device connects to the tip conductor, and the Tx- line is
connected to the ring. This requires that the transmit pair of each device be connected to the receive pair of the device on the other end. When a terminal device is connected to a switch or
hub, this crossover is done internally in the switch or hub. A standard straight through cable is used for this purpose where each pin of the connector on one end is connected to the
corresponding pin on the other connector.
DHCP
Dynamic Host Configuration Protocol (DHCP) is a network application protocol used by devices (DHCP clients) to obtain configuration information for operation in an Internet Protocol
network. This protocol reduces system administration workload, allowing devices to be added to the network with little or no manual intervention.

Network Utility
Program
Simple Windows-based utility program (EVIPSetup.exe) that needs no software installation. It is used to display the Smartpack and Compack controller’s network parameters, when connected
to an Ethernet LAN. Also, it enables changing the controller’s IP address, configuring the controller via a standard Web browser and upgrading the controller’s firmware.
Ethernet
Local Area Network technology. Ethernet provides data transfer using a baseband (single-channel) communication technique. Ethernet uses carrier sense multiple access collision detection
(CSMA/CD) that prevents network failures when two devices attempt to access the network at the same time. A 10/100 Ethernet port supports 10BASE-T and 100BASE-TX.

FTP Server
Trivial File Transfer Protocol Server (TFTP). A host to provide services according to TFTP; a TCP/IP standard protocol for file transfer with minimal capability and overhead depending on UDP
for ts datagram delivery service.
GUI
Pronounced GOO-ee. Acronym for graphical user interface. A program interface that takes advantage of the computer's graphics capabilities to make the program easier to use. Well-designed
graphical user interfaces can free the user from learning complex command languages. On the other hand, many users find that they work more effectively with a command-driven interface,
especially if they already know the command language.
HUB
A common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to
the other ports so that all segments of the LAN can see all packets.
I/O
Short for Input /Output. The term I/O is used to describe any program, operation or device that transfers data to or from a computer and to or from a peripheral device. Every transfer is an
output from one device and an input into another.
