DuraStation™ EV Charger User Manual
Cat5 – This is a twisted pair cable standard for carrying signals. This cabling is used for Ethernet
and other networks. Maximum Ethernet Cat5 cable distance is 100 meters or 328ft.
VLAN or Virtual LAN – This is a group of hosts with a common set of requirements that
communicate as if they were attached to the same broadcast domain, regardless of their
physical location. A VLAN has the same attributes as a physical local area network (LAN), but it
allows for end stations to be grouped together even if they are not located on the same network
switch. VLAN membership can be configured through software instead or by physically
relocating devices or connections.
IP Address – An Internet Protocol address (IP address) is a numerical label assigned to each
device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol
for communication.
Subnet Mask – The subnet mask determines how the IP address is divided into network and host
parts.
Default Gateway or LAN Gateway – A node on a TCP/IP network that serves as an access point
to another network. A default gateway is the node on the computer network that network
software uses when an IP address does not match any other routes in the routing table.
DHCP – DHCP (Dynamic Host Configuration Protocol) is a communications protocol that lets
administrators centrally manage and automate the assignment of Internet Protocol (IP)
addresses in a network.
DNS – Domain Name Server – A DNS server translates Internet domain and host names to IP
addresses.
Internet Port – Every service that you connect to on the Internet listens on a particular port. For
example the World Wide Web Service listens on port 80. Whenever you go to a website, your
browser is actually connecting to a particular computer on its port 80. Other services use other
ports.
Topology – In a network LAN the topology is the structure of nodes and how they connect to one
another.
Static IP Route – A static IP route is way or directing network traffic through a specific path or
gateway. In order to reach other networks it is sometimes necessary to configure specific routes
to override the default gateway path.
BMS – Building Management System – This is a computer-based control system installed in
buildings that controls and monitors the building's mechanical and electrical equipment such as
ventilation, lighting, power systems, fire systems, and security systems.
