Overview
ELM320 OBD (PWM) to RS232 Interpreter Description Since the 1996 model year, North American automobiles have been required to provide an OBD, or On Board Diagnostics, port for the connection of test equipment.
Data is transferred serially between the vehicle and the external equipment using this connection, in a manner specified by the Society of Automotive Engineers (SAE) standards.
In addition to operating at different voltage levels, these ports also use a data format that is not compatible with the standard used for personal computers.
The ELM320 is an 8 pin integrated circuit that is able to change the data rate and reformat the OBD signals into easily recognized ASCII characters.
