Types of cables, differences
For new installations the cables with the highest possible data throughput should be used to
guarantee its future. For the distribution in the secondary area OWG or Cat 6A cables or higher
should be used if possible, while in the tertiary area Cat 5e cables would be sufficient for most
applications.
The ABB-Welcome IP devices are designed for connection with Cat 5e cables.
Cat 5e is the globally most used installation cable. It makes transmission rates of up to 1,000
Mbits/s possible. It exists in loadings TIA-568 A and TIA-568 B. These two types must not be
combined in a system. It should therefore be ensured that when selecting new components,
they match the remaining components in the system. For new installations, almost TIA-568 A
have been used exclusively. Many devices recognize the connection type used automatically
and adjust accordingly.
High data rates can be attained by means of cable shields, short distances and high-quality
devices. The maximum cable length between two devices must nor exceed 100 m.
If higher transmission rates are required, Cat 6A cable can be used. This makes transmission
rates up to 10 Gbit/s possible.
OWG are mainly used for the distribution between buildings. This makes longer transmission
distances possible. It can also be used for the distribution in the building, especially for the
vertical storey distribution. The transmission of the data between OWG and copper cables is
made via media converters.
5.2.2 Integration ABB-free@home
®
Next to door communication, the indoor stations are also the interface to different additional
systems. All compatible systems are perfectly integrated into the user interface. Their functions
can be combined system-linking via the indoor station and with the door communication.
ABB-free@home
®
The connection of the ABB-free@home
®
system to the simple building control is made per LAN
or WLAN via a router to the System Access Point (SysAP).
The indoor station makes system-linking applications possible. Actions can be triggered,
sensors monitored and rules programmed.
For cable-bound versions all devices are connected via two-wire busline. The two wires are
used both for data transmission and energy supply. The wireless version builds up a coded
mesh radio network automatically and can therefore, at a corresponding distribution of the
devices, respond well to the changes of the compilation.
Commissioning of ABB-free@home
®
is carried out via the Web interface of the indoor station.
After the login with your myABB account you can also access all functions outside the home
network.
