PPENDIX
TM
FxB
protocol has greatly improved the reliability of 1-Wire® slave-based networks. The
TM
FxB
protocol has 100 times the noise immunity of 1-Wire® and 20 times the parasitic power
available to the slave.
A network must consist entirely of FxB
with the addition of the FxB
from the main communications bus and translates them into compatible 1-Wire® waveforms.
The 1-Wire® bus behind the translator can be a maximum of 4 inches long. Translators are
available in either chip level (for inclusion in new packages) or packaged (for retrofitting
existing slaves).

The LINK
devices automatically recognize a bus based upon FxB
