7 LON A Lonworks line (polarity insensitive)
8 LON B Lonworks line (polarity insensitive)
Network Termination
When building a Lonworks system the network must be properly terminated by positioning
BTK-6000 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 no terminator must be inserted in the reader, since it
is internally integrated.
