Network Termination
When building a Lonworks system the network must be properly terminated by positioning
BTK-6000 terminator in the DX6400 master reader and in the last DX6400 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:
Slave
Master
Male
Female

NOTE
For Fieldbus models no terminator must be inserted in the reader, since it
is internally integrated.
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 DX6400 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 BTK6000 terminator
(see par. Figure 25 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 always terminated to close
the system network.
The following diagram represents the connection between a DX6400-XXX-010 working as
master and a DX6400-XXX-010 working as a slave reader.
The cable shield for LON A/B is connected to pin 1 - CHASSIS.
