way address is the IP address of the gateway on a network. Contact the network
administrator for the gateway address for your network.

DNS Address:
a Domain Name System (DNS) is a service that translates names into
IP addresses. This service allows for using human readable names for devices on a
network. As an example, when a web browser attempts to retrieve the web page
at www.lakeshore.com, the browser first performs a forward-lookup on the
assigned DNS server to attempt to retrieve the IP address that is represented by
the name www.lakeshore.com. If successful, the web browser then uses the
retrieved IP address to communicate with the web server that hosts the website
at www.lakeshore.com.
4.4.2.4 Network Address Configuration Methods
The network address parameters of the teslameter can be configured using one of
two methods: DHCP or Static-IP. DHCP is an automatic configuration method while
Static-IP requires manual configuration. If supported by the server, DHCP can also be
used to automatically configure DNS server addresses, as well as IP address parame-
ters.
Dynamic Host Configuration Protocol (DHCP):
DHCP is a method of automatically configur-
ing the IP address, subnet mask, and gateway of Ethernet devices on a network. This
method provides simple automatic configuration for users connecting to a network
that provides a DHCP server. The network DHCP server will provide an IP address, sub-
net mask, and gateway address. Depending on the DHCP server configuration, it may
also provide primary DNS and secondary DNS addresses as well. DHCP is the simplest
method of IP configuration. DHCP does have the disadvantage of not necessarily pre-
serving the IP address through a device reconfiguration, as well as the possibility of
being automatically reconfigured when the DHCP “lease” expires. Contact your net-
work administrator to find out the DHCP lease policy on your network.
Static-IP:
Static-IP is a method of manually configuring the IP address, subnet mask,
and gateway of network enabled devices. When using the Static-IP method, the IP
address, subnet mask, and gateway must be configured appropriately for the con-
nected network, or for the connected PC, in order to establish connection to the net-
work. A major advantage to the Static-IP method is that the IP address will not
change during device reconfiguration (power cycle). Disadvantages of using the
Static-IP method include the requirement of knowing how your network is config-
ured in order to choose the correct configuration parameters.
Domain Name:
A domain is a collection of network devices that are managed according
to some common characteristic of its members. Domains can contain subdomains,
which are subsets within the domain. The hierarchy can contain several dot-sepa-
rated levels which flow from right to left. For example, lakeshore.com contains the
top-level-domain “com” and the subdomain “lakeshore”. When using the Domain
Name System (DNS) to connect to a specific host device on a network, the device’s
hostname is tacked onto the left of the domain name. For example, the “www”” in
www.lakeshore.com refers to the Lake Shore web server, located within the internet
domain “lakeshore.com.”
4.4.2.5 TCP Socket Communication
A TCP socket connection interface is provided as the communication medium for the
network interface of the F71/F41 teslameter. A TCP socket connection, or simply
“socket connection”, is a common connection protocol used by Ethernet devices. The
Transmission Control Protocol (TCP) is commonly used for creating a communication
channel between one program on one computer and one program on another com-
puter, for example a web browser on a PC and a web server on the Internet. In the case
