LIN Monitor
Description
LIN or ‘Local Interconnect Network’ is a low cost
and relatively simple networking system that is used
predominantly in the automotive world. Recently, it
has been gaining in popularity, with proposals to use
it in major appliances as well. For more information,
visit the LIN web site (http://www.lin-subbus.de/).
The ELM630 is a monitoring device designed
for troubleshooting LIN bus systems. It is capable of
continually monitoring a LIN network, translating the
LIN messages to standard ASCII characters, and re-
transmitting them to an RS232 system (personal
computer or PDA) for display and possibly analysis.
The baud rate measurements, data formatting,
synchronizing, and checksum calculations are all
done for you by the ELM630.
The LIN specification has recently been updated
to revision 2.0, incorporating several improvements.
The ELM630 has been updated to be compatible
with this new specification, as well as the previous
ones.
