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 DX8200A master usually employs the 17-pin female connector for output connection to
the first slave, while the 17-pin male connector is terminated by inserting the BTK-8102
terminator (see Figure 17 for details).
Both connectors are always employed when connecting together the slave readers. In
particular, the 17-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
BTK-8100 bus return to close the system network.
The following diagram represents the connection between a DX8200A working as master
and a DX8200A working as a slave reader.
The cable shields for LON A/B are connected to pin 1 and pin 3 - CHASSIS.
