5 Data technology
Data technology used wide range applica-
tions.
• V11 interface
V11 the German designation for the RS422.3. OBO also offers host pro-
tective devices that are simple install, depending on
the particular application.2
km with data rate Mbit/s (dependent upon seri-
al controllers).3.
• RS232 interface
The RS232 frequently used interface. Al-
though now largely replaced the USB interface, the
RS232 standard still frequently used for control
lines. This enables cable
lengths several hundred metres realised.
• TTY system
Unlike the RS232 other serial interfaces, the TTY
system not voltage-controlled instead delivers
an imposed current (4–20 mA). The stand-
ard includes cable and connector types such as
RJ45. extends from the simple installation print-
er connected complex networks with sever-
al thousand clients.
Ethernet
Ethernet the standard technology for networked
computer systems today.2.
There range interfaces for different applica-
tions: from bus lines for telecommunication and data
transfer through simple terminal devices such as
printers scanners. 1.
• RS485 interface
The RS485 industrial bus interface differs slightly from
the RS422 that the RS485 enables the connection
of several transmitters and receivers (up users)
via protocol. The maximum length this bus sys-
tem, when twisted-pair cables are used, approx.
• V24 interface
V24 the German designation for RS232. all cases, careful planning of
surge protection measures required, taking account
of the data interfaces hand. Specified data transmission
rates range from Mbit/s much Gbit/s
today, and the data can transmitted over both clas-
sic copper cables and fibre optic cables. The system can de-
signed for maximum eight data lines, although
two are always used send and receive lines. The
American nomenclature, however, the most widely
used. used,
for example, for modems and other peripherals. The Amer-
ican nomenclature, however, the most widely used.
• RS422 interface
The RS422 serial high-speed standard suitable
for communication between maximum ten users,
which designed bus.
