2.7.5 Local Lonworks Network
A local Lonworks network allows electrically connecting a DS6500 master reader up to 31
DS6500 slaves. Actually, the maximum number of readers to be employed in the network
depends on the system operating conditions, that is adopted operating mode and amount of
data stream. For example, the On Line operating mode, (see Genius™ Help On-Line for
further details), typically supports a maximum number of 8 slave readers.
Whenever creating your network, always keep in mind the following guidelines:
•
the network electrically supports a maximum number of 31 DS6500 readers and may
extend up to 130 m (426.5 ft);
•
the maximum number of DS6500 readers supported depends on the type of power
propagation adopted by the system (see par. 2.3.6 for details).
Contact Datalogic S.p.A., if your network requires a higher number of readers or in case the
application throughput is very high.
When building the network, the DS6500 master reader must be connected to a local host
computer or a C-BOX 100 by means of a cable connected to the 25 D-sub male connector.
The local Lonworks 9-pin female connector connects the master reader to the first slave
reader of the system, while the local Lonworks 9-pin male connector must be properly
terminated by inserting the BTK-6000 terminator.
The slave readers are connected together through the local Lonworks connectors. Only the
9-pin female connector of the last slave reader must be terminated by the BTK-6000
terminator.
Single P.S.
The presence sensor is connected to the C-BOX 100 and is unique to the system. There is
only a single reading phase and a single message from the master reader to the Local Host.
The
On-Line
operating mode is used for this layout.
