12.7.11 Wi-Fi Module or Maintenance Port Interface

The Wi-Fi Module interface is used to connect to the FWF-125 Wi-Fi Module (FDL-978-XVRL
only) for receiving ADS-B TIS/FIS data wirelessly on the pilots PED (e.g. iPad or Android
device) through a Wi-Fi connection. An Android tablet ADS-B MPI application can also be used
to configure the system and check system installation status through the Wi-Fi module. The Wi-
Fi module interface pins are as follows:
PIN SIGNAL
26 Wi-Fi Module
Input
42 Wi-Fi Module
Output
19 Wi-Fi Data Gnd
When installing the FDL-978-TXL Transmitter, which does not include a Wi-Fi module, a female
DB-9 connector should be mounted in the aircraft for easy Maintenance Port Interface (MPI)
access. The MPI can be used to configure the system, provide installation status information,
and update system software/firmware. The DB-9 connector allows connection to a battery
powered Serial-to-Wi-Fi MPI Module. The Wi-Fi MPI Module (P/N 87710-00) allows Wi-Fi
connection to the Android tablet ADS-B MPI application for configuration and installation
status/troubleshooting. The standard RS-232 DB-9 connections are shown in the table below:
