ELM327 - OBD to RS232 Interpreter

Description

Almost all of the automobiles produced today are required, by law, to provide an interface for the connection of diagnostic test equipment.

The data transfer on these interfaces follow several standards, but none of them are directly usable by PCs or smart devices.

Features

  • in detail, how to use it and configure it, as well as providing some background information on the protocols that are supported. There are also schematic diagrams and tips to help you to interface to microprocessors, construct a basic scan tool, and to use the low power mode.

ELM327 OBD to RS232 Interpreter Description Almost all of the automobiles produced today are required, by law, to provide an interface for the connection of diagnostic test equipment. The data transfer on these interfaces follow several standards, but none of them are directly usable by PCs or smart devices. The ELM327 is designed to act as a bridge between these On-Board Diagnostics (OBD) ports and a standard RS232 serial interface. In addition to being able to automatically detect and interpret nine OBD protocols, the ELM327 also provides support for high speed communications, a low power sleep mode, and the J1939 truck and bus standard. It is also completely customizable, should you wish to alter it to more closely suit your needs.
