Interface (MPI) 1

[Natali]

General

The Multi Protocol Interface (MPI) allows your computer to communicate with modules using appropriate protocol and wiring.  The MPI translates the different module protocols and signals into a standard RS-232 based protocol that is suitable for your personal computer.

Hardware

The MPI includes 2 communication connectors and one power jack located on the back panel of the box (see figure below).  On top, there is a DESS® key housing and three status LEDS.  The following table lists the MPI hardware components:

 

Component	Description
Serial port	Connects the MPI to your computer (computer icon).
Diagnostic port	Connects the MPI to the vehicle (engine icon).
Power jack	Connects the MPI into a domestic power outlet.
Internal battery pack	Four AA batteries located underneath the MPI.
DESS key housing	Allows you to program DESS keys.
ON LED	Indicates that the MPI is powered.  The LED blinks when the MPI is powered by the internal battery pack.
Rx/Tx MPEM LED	Indicates that the MPI is transffering data to a module.
Rx/Tx PC LED	Indicates that the MPI is transffering data to your computer.

 

 

 

 

 

 

Software

The MPI contains identification parameters.  Upon startup, B.U.D.S. reads these parameters and displays them into the MPI Information window.
