5.1 NETWORK TERMINATION
When building a Lonworks system the network must be properly terminated by positioning
the BT-6000 Lonworks terminator in the DS6400 master reader and in the last DS6400 slave
reader.
Each side of the terminator provides a different connector; thus, it can be inserted either into
the Lonworks 9-pin male connector of the master reader or in the Lonworks 9-pin female
connector of the last slave reader:

NOTE
For Fieldbus models (Ethernet, DeviceNet, or Profibus), no terminator must
be inserted in the reader, since it is internally integrated.
5.2 LONWORKS INTERFACE
The Lonworks network is used for both input and output connection to build a multi-sided or
omni-station system connecting several readers.
The DS6400 master usually employs the 9-pin female connector for output connection to the
first slave, while the 9-pin male connector is terminated by inserting the BT-6000 terminator
(see Figure 71 for details). If creating a T-network configuration, it is necessary to use both
connectors to create the double branch line of slave readers.
Both connectors are always employed when connecting together the slave readers. In
particular, the 9-pin female connector is used for output connection and the male one for
input connection. The female connector in the last slave reader is terminated by the BT-6000
to close the system network.
