Connection / operating modes
To be able to send data from one network subscriber (PC, e-Box, etc.) to another, communication must be established
between the two subscribers and be open for data transfer. For this to be possible, the system must have rules as to
which subscriber takes on the active (client) role, and which takes on the passive (server) role.
The behavior of each balance in the network is defined by the corresponding configuration of the server and client
interface settings. The server and client settings enable two different types of connection: A dedicated connection or
an open connection.
Dedicated connection
With a dedicated connection the user determines in the balance with which devices the balance is allowed to connect
and communicate. To enable a dedicated connection of a balance, the balance must be activated as client (the server
can be switched on or off). If the client mode is activated, the IP-Address of the dedicated device must be defined.
Example1: Balance is connected to a network with several printers. The balance must send its data only to

When a balance is connected to a network with several PCs (host). The server mode in the balance must be activated
as well. In this case only the PC that is defined in the balance under “Remote Host Address” can make a connection
with the balance server. The balance and PC are both activated as client and server. This configuration offers the most
secure communication between two instruments.

Connection to more than one peripheral
Compared to other interfaces (with exception of LocalCAN), the Ethernet interface of the balance can communicate
at the same time with different devices:
Example 4: The balance is configured to communicate with a printer, PC, tablet feeder and a secondary display
over the network.
For each device only one connection can be made at the same time. It
is for example not possible that two printers or two PCs can have a connection with the balance. A connection with more than one device (e.g.
a PC with LabX and a LIMS System) is only possible when the balance
is only activated as server (configurated as “open connection”). The
devices must communicate temporary and after each other. Behavior with overloaded network
If no more data can be fed into the network, arriving messages are stored in a FIFO buffer, which has a size of
2560 bytes. If the buffer exceeds 80 % (> 2000 bytes) the communication from the Ethernet option to the balance
application will be stopped until the buffer is below 60 %. Each connection has two FIFO buffers; one for the incoming
data, and one for the outgoing data.

Recommendation for network integration
The following table shows recommendations for network configuration of the Ethernet interface option based on the
different communication modes:
Precondition: There is a Domain Name Server (DNS) running in your local network.
Communication mode
(how to talk to a device)
Network configuration of the
balance
Network setup
(ask you local network administrator for more information)
Client mode
(Parameter CommMode,
Client Only)
use DHCP or
static IP configuration
Make sure the device you like to communicate with (Parameter “Remote
Host Address”) has its FQDN updated
in the DNS.
Server or Client & Server mode
(Parameter CommMode,
Server Only or Client & Server)
use DHCP
In the DHCP server reserve an IPAddress for the balance using “MAC
reservation” (see section 4, how to
find out the MAC address of your
balance). Your DHCP administrator
can do that for you. Enter the FQDN
for the assigned IP-Address in the
DNS (forward and reverse zone).
Your DNS administrator can do that
for you.
or static IP configuration
Enter the FQDN for the static IPAddress in the DNS (forward and
reverse zone). Your DNS administrator can do that for you
Using FQDN
We generally recommend the use of a FQDN (Fully Qualified Domain Name), i.e. Hostname plus Domain name, instead of an IP-Address in “dot”-notation (e.g. “172.24.130.88”). For example :
Devices & Network
Name

Interface and Application settings
Before you can start with the configuration, you need to collect various items of information about the network which
is to be created. The information needed is:
• A network overview (which has to be created) showing:
– What components are present in the network?
– Who communicates with whom?
– Who can initiate communication via the network and who can terminate it?
• Determination and input of the following data items for each Ethernet connected balance is required:
Is DHCP supported? If yes, no further information is required. If not, than following information is required:
– IP-Address and subnet mask (request from network administrator).
– If necessary, also the default gateway address and the domain name server address (request from network
administrator).
– Additional information about the location, type, etc. of the connected measuring instrument.
• Check the availability of network connections at the locations of the measuring instruments. If necessary, arrange
for them to be installed.
• Work out which department and/or person (IT, Quality Assurance, METTLER TOLEDO technician, etc.) will set up
which system components, and configure, test, and release them.
Once you have collected all this information, you can get started.

Ethernet option settings
The Ethernet interface parameters listed here are for all peripherals identical to whom the balance can communicate
with. This section gives an overview of all parameters. Find the detailed information of each parameter in the corresponding sections mentioned below.
The aim of most networked balances is to control them by a computer application, the examples in the following
sections are therefore showing screenshots of the “host” parameters and settings.
The following settings are available:
“Communication mode”: With this parameter the communication behaviour of the balance must be set.
Selection is between: “Client Only”, “Server Only” (default) or “Client & Server”. “Client Only”
allows to activate a client connection. The parameters
Remote Host Adress and Remote Host Port Number must
be set as well.
“Server Only” allows to activate a server connection. The parameter Local
ServerPort Number must be set as well.
Please note: With “Server Only” the client that first establishes a connection receives any data back.
“Client & Server” “Remote Host Adress”: Enter the IP-Address of the device to which the balance will connect to as client.
(Only active if “Client Only” or “Client & Server” is selected).
“Remote Host Port Number”: Enter the port number of the host computer. With the port number you specify the
port via which the balance can establish contact with the host computer. The port
number has to correspond to the host.server port (when the host is an e-Box, the
corresponding port number of the e-Box can be found under server port).
“Local Server Port Number”: Enter the port number of the built-in server (only active if “Server Only” or “Client
& Server” is selected). With the port number you specify the port via which an
external client (e.g. a computer) can establish communication with the balance.
If configured as an open connection (i.e. no client, server-only mode), the port
number has to be unique within all configurated peripherals on the balance: e.g. a
printer configurated as open connection (server only) on Port 8002 and a Barcode
reader on the same server port (8002), is not allowed (an error message will be
displayed: .Server with this port number already exists.). In this case an unused
act as a client and a server (accepting only the device at
the Remote Host Address)
Interface and Application settings
13
port number for the Barcode reader must be set, e.g. Port 8005. Following server
port numbers are recommended:
8001 = Host
8002 = Printer 8003 = Feeder 8004 = Second Display
8005 = Barcode 8006 = Label Printer
“End of Line”: Set the end of line. <CR><LF> (default), <CR>, <LR>
3.3
8007 = Reference Balance
8009 = General IO
8010 = Foot switch
8011 = Relais box
8012 = Keyboard
Global settings
You use the parameter settings to specify the operating mode and communication characteristics of the balance to
suit the network application or device it must communicate with.
When the balance will be integrated into a METTLER TOLEDO application such as LabX or FreeWeigh than look in
the next chapter, where the specific settings are already described. Also the communication with other device that are
connected with e-Link to the network are described as well (section 3.4)
If you want to configure the balance for an application of your own, continue with this section, where you find detailed
information about the all the individual parameters.
3.3.1 DHCP (Dynamic Host Configuration Protocol)
Using the Ethernet set of protocols (TCP/IP),each machine that can
connect to the Ethernet needs a unique IP-Address. When a network of
balances or other devices is set up, all devices must have an IP-Address
be assigned to each one.
DHCP (Dynamic Host Configuration Protocol) is a protocol that lets
network administrators manage centrally and automate the assignment
of all necessary network parameters (IP-Address, Subnet Mask, Standard
Gateway, Domain Name Server) in a network. DHCP lets a network administrator supervise and distribute IP-Addresses from a central point and
automatically sends a new IP-Address when a computer is plugged into a
different place in the network. If the DHCP is switched on, the IP-Address,
subnet mask, Standard Gateway and Domain Name Server are all set by
DHCP. These parameters are read-only that show the values assigned
by the DHCP server. They can’t be modified in the balance.
When DHCP is switched off, the IP-Address, Subnet Mask, Standard
Gateway, and Domain Name Server must be entered manually for each
balance or if balances move to another location in another part of the
network, a new IP-Address must be entered as well.
Interface and Application settings
14
3.3.2 Manual setting of balance network parameters
If the communication between the balance and network is not established by DHCP, but using a fix IP-Address, the
DHCP mode must first be switched off to make the Ethernet parameter of the balance available. If the DHCP mode is
switched “ON” or “OFF” it takes about 15 seconds initialising the parameter settings before they are available:
The parameters IP-Address, Subnet Mask, Standard Gateway, Domain
Name Server and Hostname are the (global) Network parameters for
the Ethernet interface. Althought they are shown in every peripheral
setting (Host, printer, second display, etc.), they are the same for each
connection. These five parameters can only be set if the DHCP mode
is switched off.
Note: The IP-Address and Gateway must be defined within the same
Subnet. If not, an error message will appear in the balance display, and
the settings of the IP-Address, Subnet and Gateway are not saved.
The parameter settings shown are factory default settings.
Note: After switching the DHCP mode “ON” or “OFF”, leave the peripheral
configuration by pressing “OK” and then we recommend to restart the
balance, by shortly unplug it from the power.
“IP-Address”
Set the IP-Address of the balance in format
“XXX.XXX.XXX.XXX”. The IP-Address must
be unique within a company network and
conform the conventions for IP-Addresses.
If the IP-Address is invalid or already used,
you will be notified by a warning window on
the balance display.
“Subnet mask”
Set the subnet within which the balance is
addressable. The Format is equal to the IPaddress: “XXX.XXX.XXX.XXX”.
“Standard Gateway”
Is required if the network is connected via
a router to another network, the addresses
of the respective standard gateway must be
entered in this field.
Format “XXX.XXX.XXX.XXX”
“Domain name Server” If the TCP/IP network supports domain names
for calling up network subscribers, the address
of the Domain Name Server must be entered
here.
Format “XXX.XXX.XXX.XXX”
“Hostname”
Shows the given FQDN, when besides a
Domain name server also a name of the
balance is defined. A Hostname can only be
showed when a DNS is set. The Hostname
can only be displayed by the balance and
not be changed (independent if DHCP is On
or Off).

Connection with LabX or FreeWeigh.Net Application
METTLER TOLEDO software applications like LabX or FreeWeigh.Net operate both as a host applications which can
communicate directly with the measuring instrument via an Ethernet network. For use with LabX, the balance Ethernet
interfaces can be configurated as server or as server and client. For the use with FreeWeigh.Net, all balance Ethernet
interfaces must be configured both as a server and as a client.
Example: FreeWeigh.Net with IP-Address 146.21.157.6, server port 8000, and host port 8001

If the factory settings are used and the correct IP-Address for the host computer is entered, the following procedure
will take place:
– When LabX or FreeWeigh.Net starts it establishes communication with all balance Ethernet Interfaces.
– If a Balance with an Ethernet interface is switched on after LabX or FreeWeigh.Net (e.g. after a restart or power
outage), it intiates communication with the specified host computer. LabX or FreeWeigh.Net then initializes communication with the Ethernet inteface in question and closes down the communication that was initialized by the
Ethernet interface. In case of LabX, this only occurs when LabX is configured as server and client.
– LabX or FreeWeigh.Net holds the communication permanently open.
– The measuring instrument can transmit data to LabX or FreeWeigh.Net via the Ethernet interface without being
prompted.
3.5
Connection to an e-Link box.
A balance with an Ethernet interface can communicate with other peripherals that are connected with an e-Box to the
Ethernet. The e-Box itself can, depending on the requirements or application set as Client only, Server only Client &
Server or Gateway (Multiplexer). This enables the following communication possibilities with a Ethernet connected
balance:

Updating the Software
The Ethernet interface contains its own software, stored on the interface. It is possible that during the lifetime the
interface needs to be updated. When a new version comes available it can be downloaded as file from our support
website at: http://www.mt.com/balance-support. The software available on the Internet has been developed and
tested by Mettler-Toledo AG in processes which comply with the guidelines of ISO 9001. However, Mettler-Toledo AG
accepts no responsibility for any consequences of using this software.
Downloading the software update from the website
1. Call up website http://www.mt.com/balance-support
2. Register to have access to the support site.
3. Select the desired Ethernet interface software file
4. Save the file on your computer by clicking the right button with “saving as”.
Performing the software update
When the software file is on your computer, save this in a specific folder on your hard disk (e.g: C:\EthernetOptionSWupdate). Before updating the software of the Ethernet Option, you have to know the IP-Address (e.g.: 172.24.130.12).
The software update is done with the File Transfer Protocol (FTP), this enables to send data packets directly to an
external server over the network.
Starting the update procedure in Windows (commands that need to be entered are in bold):
1. Go to “Start” and select “Run”
2. Typ in “cmd” and click OK 3. Change the directory to where the software file was stored:
– H:\>C:
– C:\>cd EthernetOptionSwUpdate
4. Type in the IP address to where the file must be sent to with FTP: – C:\EthernetOptionSwUpdate>ftp 172.24.130.12
5. The Ethernet interface will respond when the connection is made:
– Connected to 172.24.130.12.
– 220 NET+ARM FTP Server 1.0 ready.
6. As the FTP communication is always password protected you are requested to give the Username and Password. The default Username and Password are “ADMIN” and “BUp2Date!”. In Excellence balances use
the Username and password of the balance's administrator:
– User (172.24.130.12:(none)): ADMIN
– 331 User ADMIN OK, send password.
– Password: BUp2Date! (the password is not visible)
– 230 Password OK.
Updating the Software

7. Enter the command “put” and the filename of the software update: – ftp> put SN11670910A_EthOption_1-10.bin
– The software update will now be executed
– 200 PORT command OK.
– 150 About to open data connection.
– 226 Transfer complete
– ftp: 608004 bytes sent in 4.84 Seconds 125.54 Kbytes/sec.
8. After the Sofware update has been transmitted, leave the FTP mode with the command “bye”:
– ftp> bye
9. Please wait 20 seconds. The FLASH memory is now “burned” with the new software
10. Restart the balance by unplugging it shortly from the power.

A short network ABC
10BaseT / 100BaseT
10BaseT refers to an Ethernet cabling system with twisted-pair copper cables
capable of transmitting up to 10 Mbps.
100BaseT refers to a group of Ethernet cabling systems with twisted-pair
copper cables capable of transmitting 100 Mbps.
Browser
Software that enables a client PC to call up information on the Internet. Netscape
and Microsoft Internet Explorer are the most commonly used browsers.
Client A computer in a network (LAN or WAN, e.g. Internet) which uses data, services,
or resources of a server.
Default gateway The computer that receives all packets which are not addressed to computers
in the local network.
DHCP
The Dynamic Host Configuration Protocol is used to automatically assign
to client PCs a currently unused IP-Address from an address pool. Other
information such as the name of the domain, the standard gateway, and
the responsible DNS server can also be transferred to the client.
DNS
DNS (Domain Name Service) is a database available on a names server
for converting computer names into IP-Addresses and vice versa. Each
server and each LAN which is connected to the Internet must have its information stored on a DNS server. When a server in the network (Internet or
intranet) is addressed, the browser first asks a Domain Name Server. This
replies with the corresponding numerical address, which enables the browser
to set up direct communication with the IP-Address.
Domain
An individual computer or several computers on a network which are grouped
together under a single name.
Download
Downloading means copying data over a network from a computer which is
acting as a server (e.g. downloading a new software version from an Internet
site).
Ethernet
A networking standard under which all computers connected to the network
can communicate with each other directly. The Ethernet standard was developed by the Intel and Xerox corporations. Its purpose is to make data and
peripherals (printers, servers, etc.) available to other users. The transmission
speed is limited to 10 Mbits/s, in contrast to its successor Fast-Ethernet which
can handle speeds of around 100 Mbits/s (but which uses a different sort
of cable). The enormous advantage of an Ethernet network is that further
computers or peripherals can be added at any time which can use the same
services as the other computers.
Firewall A computer located on the Internet side of a local area network and over which
access to the Internet has to pass. Firewalls can be used by companies or
organizations to allow connected computers to access the Internet, but to
completely prevent access to the network from the Internet.
FQDN
FQDN (Fully Qualified Domain Name). A FQDN allows the use of a Hostname
plus domain name instead of an IP-Address in “dot”-notation. Instead of
“172.24.130.88” we might use “balance-88.myhome.net”.
Appendix
26
FTP
FTP (File Transfer Protocol) technologies enable direct, password-protected
communication with an external server to which data packets can be directly
transmitted without third parties being able to gain access to the data while
it is being transported on the web.
Gateway A gateway is an interface between two networks. A gateway computer is a
special computer which is connected to both networks. These may use different
protocols. A gateway can also be an interface from one logical (frequently
purely organizational) network to another, both of which use the same protocol.
For example, two LANs can be connected by a gateway. All messages from
one LAN to the other must pass through the gateway computer.
Handshake
Method of synchronizing data transmission with irregular occurrence of
data. The transmitter signals when he can/wishes to send new data and the
receiver when he can/wishes to process new data.
1. If the synchronization is effected by means of electric cables, it is referred to as a hardware handshake.
2. Synchronization by transmission of control characters is referred to as a software handshake.
A hardware handshake is faster than a software handshake because it does
not require any characters to be transmitted.
Host
A general term for a computer or server (on which generally services of
some sort are made available for users). The term is frequently used for the
computer to which a data connection has been established.
HTML
HTML (Hypertext Markup Language) is a script programming language with
which documents on the WWW are programmed. One of the most important features of HTML is that hypertext links can be inserted in documents.
Hypertext links allow another WWW document to be loaded into the WWW
browser simply by clicking on the (hyper)link. One document may contain
links to many other related documents. These documents may be on the
same computer as the original document, or on another computer which
may be on the other side of the world.
HTTP
HTTP (HyperText Transfer Protocol) is a protocol interacting with TCP/IP with
which WWW servers and WWW clients communicate to call up efficiently
information which is linked via hypermedia links. HTTP, which is the abbreviation for “Hypertext Transmission Protocol”, is responsible for handling
HTML documents within the World Wide Web (WWW).
HTTP server See web server.
Hub
A network device to which several computers of a network are connected to
create a star-shaped, structured topology of LAN nodes, which has connections for data stations and further hubs. Hubs serve to distribute data flows
within and between LANs.
Intranet An internal network which uses the same technology as the Internet to interconnect users. Browsers are used to create a common user interface. An
Intranet can be used all over the world.
Appendix
27
IP-Address A classical IP-Address consists of four bytes (IPv4) or four quads which are
separated from each other by dots.
Example: 130.5.18.26.
The left-hand (bold) part of the IP-Address represents the network number,
the right-hand part the address of the computer or network device. Depending
on the class (A, B, C) of the IP-Address, more or less blocks belong to the
network number. Example: In a class B network up to 65,536 computers
can be addressed, but in a class C network only up to 256.
Private IP-Addresses:
In contrast to public IP-Addresses, private IP-Addresses are not assigned to
an organization by the IANA (Internet Assigned Numbers Authority). They can
therefore be used internally by any organization. However, this requires that
these addresses are not routed anywhere in the world. Because of this, any
computers which have a private IP-Address are only addressable within their
own organization. The ranges reserved by the IANA for this purpose are:
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
Specially reserved IP-Addresses:
0.0.0.0 127.xxx.xxx.xxx xxx.xxx.xxx.255 xxx.xxx.xxx.0 xxx.xxx.0.0 xxx.0.0.0 The IP-Address is used for addressing computers, web servers, or printers
in a TCP/IP network. Normally however, IP numbers are only used for addressing within programs. On the user interface clear-text names are normally
used - for example, domain names. The allocation of names to addresses
is handled by the DNS (see also network classes).
Local area network (LAN) A network within a limited area, e.g. within a company. It is protected against
access from the outside world (Internet) by a firewall.
MAC (address) Media Access Control is a protocol according to IEEE-802 (OSI Layer 2)
specially for Ethernet network cards. The MAC address is also referred to as
the hardware address. Essentially, it is the unique serial number of a network
card or a network device. An address is represented by 6 hexadecimal pairs:
e.g. 00-30-67-34-00-1A.
Network classes IP/Internet: The network class depends on the number of computers within the
company or other organization which are connected to the Internet. Subnets
of the Internet are divided into classes A, B, or C. Subnets of classes A and
B are often divided internally into further subnets.
Own address which is still unknown
Address for computer-internal loopback tests
Broadcast addresses
Host address, network designation

Class A network: A class A network contains up to 16.7 million computers. A
class A network is only provided to really large companies or organizations.
IP-Addresses for class A networks are in the range from 0.xx.xx.xx to 27.xx.
xx.xx.
Class B network: A class B network contains up to 65,000 computers.
IP-Addresses for class B networks are in the range from 128.00.xx.xx to
191.255.xx.xx.
Class C network: A class C network contains up to 256 computers. IP-Addresses
for class C networks are in the range from 192.00.00.xx to 223.255.255.
xx. There can therefore be 2 million class C networks.
All IP-Addresses whose first number is greater than or equal to 224.xx.xx.
xx are reserved for technical purposes.
Node/network node Each individual computer or other device on the network.
OSI model Model for data transmission between computer systems. It describes seven
layers of abstraction which serve each other and each of which has defined
tasks and interfaces:
Layer 7
Application Layer
Layer 6
Presentation Layer
Layer 5
Session Layer
Layer 4
Transport Layer
Layer 3
Network Layer
Layer 2
Data Link Layer

Physical Layer
Ping A program which is started from the DOS input prompt and can be used to
test whether a particular computer can be reached with IP packets: e.g. PING
192.168.0.1 or PING yahoo.com.
Port number
The port number is a means of identification used for calling up a specific
process, e.g. an application, on a server which is addressed by an IP-Address.
Valid port numbers are in the range from 0 to 65535. Ports 0 to 1023 are
reserved for special services. The remaining port numbers are referred to as
dynamic or private ports.
Examples: telnet (23), ftp (21 tcp), smtp (25), http (80), pop3 (110)
Proxy A network service which deputizes for a client to set up network connections.
For example, an HTTP proxy deputizing for a display program obtains HTML
pages when it is requested to do so. This principle can be used to implement
intermediate storage and data flow control.
RFC Request For Comments: A complete series of documents from the IAB in
which the standards by which communication in the Internet will take place
are laid down. For example, RFC822 describes the specification for electronic
mail addresses. Since all technical standards on the Internet are published
in these RFCs, any manufacturer of software or hardware can use these
standards for their products.
Appendix
29
Router Routers are important for Internet traffic between different networks. They
inspect the destination addresses of data packets and send the packets on
by the best route to the next router on their way to their destination. Routers
are nothing other than small computers with a special program for deciding
the optimal routing of information.
Server A computer or other device (e.g. measuring instrument) within a network
(LAN or WAN, e.g. the Internet). When requested to do so, the server provides
data, services, or resources to other computers (clients). The converse of a
server is a client.
SMTP
Simple Mail Transfer Protocol: A transmission protocol according to RFC
821 applying specially to the exchange of electronic mail messages. It is the
standard protocol used on the Internet for this purpose. SMTP specifies how
two mail systems interact, and defines the structure of the control messages
used for this purpose.
SNMP
The Simple Network Management Protocol is used to manage TCP/IP networks.
SNMP can be used to inquire and change the properties of computers. In
certain exceptional situations a computer can send an alarm signal (SNMP
trap) to the management station.
Subnet mask
The subnet mask is used to indicate to the routers within a network which
bits in the four quads of the IP-Address must be used to seek the addressed
computer in the respective network.
255.255.255.0 in relation to the (class B) IP-Address 130.5.18.26 means
seek in network 130.5, and within that network in subnet 18, the computer
which is num­ber 26.
Switch
A switch analyzes the data traffic and establishes a connection between
devices on different sections of a LAN which exchange information.
TCP/IP TCP/IP (Transmission Control Protocol/Internet Protocol) manages the
transportation of data packets on the Internet. IP is the agreement as to
how the individual data packets should be formulated and dispatched. TCP
then handles setting up the communication and safely delivering the data
packet.
The TCP/IP protocols have become the de facto standard for data transmission. Examples of services based on the TCP/IP family are the following:
•
•
•
remote login (Telnet)
file transfer (FTP)
mail (SMTP)
Telnet The standard protocol on the Internet for remote logging on. This allows a
user to establish interactive communication to another host via the Internet
as if there were a direct connection to it from the user's terminal.
Tunneling
A method of transmitting data packets which uses one protocol to transmit
data packets which have a different protocol. For example, a protocol with
MT-SICS commands can be packed into IP packets and transported over the
Internet.
Appendix
30
Upload
Uploading is the opposite of downloading, i.e. sending data to a computer
or, for example, a measuring instrument, in a network (intranet or Internet).
Uploading frequently makes use of FTP. URL Uniform Resource Locator: The unique address of an Internet computer or
of a specific item of information on the computer: e.g. http://www.cisco.
com/ch.
Web server
A server which when requested to do so uses HTTP to transmit HTML pages
to an HTML browser.
Winsock
On PCs running under Windows, a software interface (Windows socket)
which enables programs to access network functions and the Internet.
When a winsock program (e.g. Netscape Navigator) starts, it looks in the
system directories for the file WINSOCK.DLL and loads it to gain access to
the Internet.
Problem: Many online services gain access to the Internet by means of a
special Winsock library. If a LAN is simultaneously operating network services
with TCP/IP it is possible that the WINSOCK.DLL which is active is not the
right one.
Solution: All winsock programs must be terminated before the online service
is called up. These problems obviously do not occur if access to the Internet
takes place via a central server.
Communication using TCP/IP
Communication between different devices and software on the Internet is only possible because there is a common
“language”, a transmission and communication protocol, for this purpose. This common language is called TCP/IP
and is an important component for the success of the Internet. The abbreviation stands for Transmission Control
Protocol/Internet Protocol. The protocol can be understood by all computers which are equipped with special software
to interpret and analyze it. However, TCP/IP is more than just a common language analogous to English for humans
of different nationality. TCP/IP is a standard which takes care of the technical details for transmitting data. TCP splits
up the data into digital packets ready for transmission. Each packet is put into the equivalent of an envelope which
bears the address of the sender and recipient as well as the timeframe within which the packet should be forwarded.
The packets are then sent individually via different routes to the recipient where they are reassembled. The sequence
in which reassembly must take place is also noted on the envelope or in the so-called header. It is the responsibility
of the Internet protocol (IP) to ensure that data packets are correctly delivered, which means ensuring that they find
the correct path through the Internet.
How is data transported?
Irrespective whether a user sends an e-mail or calls up a website – the data is always split up into digital packets which
have a header containing all the information necessary for transportation. Various devices process this information as
the packets travel through the Internet and send them on their way. The most important devices which communicate
between networks are bridges, gateways, routers, and switches.
Bridges link local (area) networks (LANs) to each other and ensure that data which is addressed by one LAN to
another is passed on. Bridges also hold back any data which should not be passed on. Gateways function in a
similar manner to bridges, except that they can also interpret data from other types of network. Gateways are used,
for example, to connect online services to the Internet.
