DESCRIPTION
The MicroLAN coupler is an essential component to
build and control 1–Wire MicroLAN networks with multi–
level branching. In contrast to approaches that switch
the ground line, the coupler maintains a common
ground level for the whole network and keeps the inac-
tive segments powered. This simplifies supplying cen-
tral or local power for additional circuitry and prevents
loss of status of parasitically powered devices. It also
avoids disrupting communication caused by the para-
sitic power supply of 1–Wire devices after activating a
branch. The coupler does not contain any user–pro-
grammable memory. To label a branch one can connect
any 1–Wire memory device to the auxiliary 1–Wire out-
put of the coupler. Both the main and the auxiliary
1–Wire output are supported by a “smart–on” com-
mand. This command generates a reset/presence
sequence on the selected output
before
the electronic
switch closes the contact to the 1–Wire bus. This way
the bus master can apply a ROM function command
(optionally followed by a memory function) to the
