IP
Internet Protocol
The IP is a network protocol in
widespread use in computer
networks. IP forms the first layer of
the Internet protocol family which
is independent of the transmission
medium. This means that computers
can be grouped within a network
into logical units known as subnets
by means of an IP address and
subnet mask.
IGMP V3
The Internet Group Management
Protocol is based on the Internet
Protocol (IP) and permits IP
multicasting (group communication)
in the Internet. IP multicasting is the
distribution of IP packages under
an IP address to several stations
simultaneously. Here, it is possible to
specify which source is required for
the multicast stream.
IWA
Interface Working Address
Six-digit address with which the
system interface video server
SIVS 600-... addresses the PC users.
These IWA addresses are stored in
the Software Client.
LAN
Local Area Network
Local, cable-linked network.
Monitor assignment
Up to 254 Siedle Multi door stations
can be assigned to a maximum
of 4 different PC users. This
operating mode is only possible with
DCIP 740-... .
Multicasting
Term to denote group/parallel calls
with video image to several PC users
which have the Software Client
installed. For this to be possible, the
UDP and IGMP V3 protocols must be
implemented in the network.
Push to Talk
In case of a connection using the
half-duplex mode (push to talk) a
button always has to be pushed to
change the speech direction.
Router
A router is a network device which
links several computer networks.
Network packages of a protocol
arriving at the router are analysed
for information and forwarded or
routed to the intended destination
network.
RS232
Designation for a serial interface, for
instance the COM interface of a PC.
RS485
Interface for serial data transmission
in the half-duplex mode.
Transmission to a pair of cores.
Server
A server is a program which waits to
be contacted by a client program,
after which it exchanges data with
the client program. The hardware
on which the server runs is known
as the host.
Subnet mask
The subnet mask, also known
as network mask, is a bit mask
which separates an IP address into
a network and a device or host
section. It is used in IP networks in
order to make routing decisions.
TCP
Transmission Control Protocol
The TCP is a protocol which
determines the way in which data
is exchanged between computers.
All operating systems in modern
computers have TCP capability and
use this protocol for data exchange
with other computers. The protocol
is a reliable, connection-oriented
transport protocol used in computer
networks.It is part of the internet
protocol family, which forms the
foundation of the Internet.
UDP
User Datagram Protocol
The UDP is a minimal connectionless
network protocol which belongs to
the transport layer of the Internet
protocol family. It is the task of the
UDP to assign data transmitted via
the network to the right application.
Vario bus
Various different input and control
units can be connected to the Vario
bus. It comprises 4 cores. The Vario
bus is a RS485-bus. The information
will be transfered on the Vario bus
protocol.
Web browser
Software for the display and
indication of Internet pages or
corresponding configuration pages.
E.g. Internet Explorer or Firefox.
