2.6.5 Local Lonworks Network

A local Lonworks network allows electrically connecting a DX6400/DX6500 master reader up
to 31 DX6400/DX6500 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 DX6400/DX6500 readers and
may extend up to 130 m (426.5 ft);
•
the maximum number of DX6400/DX6500 readers supported depends on the type of
power propagation adopted by the system (see par. 2.3.4 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 DX6400/DX6500 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.
