MPI Module Overview

The FreeFlight Systems (FFS) Automatic Dependent Surveillance – Broadcast (ADS-B)
Maintenance Port Interface (MPI) module is a battery powered device that communicates with
the aircraft's ADS-B equipment maintenance port. It provides Wi-Fi connectivity to an Android
device loaded with the free ADS-B MPI app.

3.4.1 MPI Module

The MPI module is connected to the aircraft's ADS-B equipment
MPI via a DB-9 female connector configured to Serial Port 5 or Port
3. This allows the ADS-B equipment configuration and functionality
to be accessed wirelessly using the ADS-B MPI app. The MPI
module USB micro-AB connector can also be connected to the
ADS-B equipment USB micro-AB maintenance connector.

3.4.2 ADS-B MPI App

The ADS-B MPI app allows the user to configure and verify ADS-B equipment settings, access
diagnostic information, log, and play back information. The location of the equipment and the
traffic received is also displayed on a graphical map.
