ELM327 OBD to RS232 Interpreter Data sheet
●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) portsand a standard RS232 interface.
●ln addition to being able to automatically detectand interpret nine OBD protocols, the ELM327 also provides support for high speed communications, alow power sleep mode, and the J1939 truck and busstandard. lt is also completely customizable, should you wish to alter it to more closely suit your needs.
●The following pages discuss all of the ELM327's 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 reduce power consumption.
■Features
●Power Control with standby mode
●RS232 baud rates to 500 kbps
●Automatically searches for protocols
