LIN Monitor

Description

Features

LIN or ‘Local Interconnect Network’ is a low cost

• Low power CMOS design

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/).

• Crystal-controlled for accuracy

• Standard ASCII character output

• Special power-on monitor mode

• Autobaud from 1200bps to 19200bps

• High speed (57600 baud) RS232 interface

• Works with LIN1.x and LIN2.0

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.
