VBus
®
In telecommunication engineering, a bus is a system for
data transfer between different parties. The VBus is a field
®
bus, developed by RESOL, which sends and receives data
packets via a voltage signal and also supplies connected de-
vices with extra-low voltage.
Full duplex
In telecommunication engineering, different communica-
tion standards are defined by their directionality. Commu-
nication that can only occur in a definite direction from
sender to receiver is called simplex, an example is radio
broadcasting.
If both parties can be sender or receiver, but never both at
the same time, as for example in amateur radio, the com-
munication is called half duplex. If all parties can send and
receive data at the same time, such as it is in telephony, the
communication is called full duplex. Like most network
/ LAN interface adapter is capable of full
devices, the VBus ®
duplex communication.
Web interface
An interface is a connection, either between 2 pieces of
equipment or between a person and a computer, Web
standing for the Internet. RESOL devices such as the
VBus / LAN interface adapter or the DL2 Schnittstellena-
®
dapter have an integrated software that can be opened
and operated in every web browser. This software is called
Web interface because it is an interface to the device
that can be accessed via the Internet.
