OBD-2/EOBD
multi-protocol interface 'ELMTester Pro327 ' as complete kit. Not only all
construction units are contained for plate assembly, but also industrially
manufactured cable (serial to the computer and OBD-2/EOBD to the vehicle).
The ELM327 is the newest addition to the OBD family, providing CAN (ISO 15765-4)
support, as well as SAE J1850 PWM, SAE J1850 VPW, ISO 9141-2 and ISO 14230-4.
ELM Electronics actually taken the best of the ELM320, the ELM322, and the
ELM323, improved on them and then added four CAN protocols.
Just as with the other ICs, the ELM327 transparently converts OBDII data into
standard ASCII characters, allowing trouble codes and operating parameters
to be easily retrieved without the need for special software. No knowledge
of data formatting, error checking, bus initiation etc. is needed either,
as the ELM327 handles all of it for you. You don't even need to know what
protocol your car 'speaks', as this IC automatically detects that for you,
too.
In addition to the protocols, we think that you will also enjoy some of the
enhancements. For example, the RS232 interface has been completely updated.
It is now a background task so it doesn't interfere with OBD receives, it
has a large data buffer to allow for fluctuations in the OBD data, and it
offers a second baud rate (38400).
There are many other features (like a battery monitoring input) that you will
only learn about
if you download either the (6 pages) ' Quick-Sheet
' or the full (59 pages) ' Data-Sheet
'.
