ELM ELM325
The ELM325 allows a PC or similar device to be used to monitor and query modules on a J1708 data bus, using simple commands that can be sent from almost any terminal program. It is able to work with either the J1587 or the J1922 data formats. 6 Electrical Characteristics 6 Using the ELM325 Overview| Part No. | ELM325 |

DESCRIPTION
With the advent of electronic engine controls, many vehicles also adopted some form of diagnostic tools to help monitor their operation. As more modules began to be used in vehicles, there was also a need for the devices to share information rather than each independently obtaining it from separate sensors. In the 1980’s, the SAE J1708 standard was created to provide a specification for a common data bus to be used in heavy duty vehicles. It used RS485 wiring (already proven to be reliable in noisy environments), and a UART-based low speed data format. The SAE J1587 standard followed a few years later to describe the mechanism by which messages and data should be sent between vehicle modules.APPLICATIONS
