The Installation Configuration Module (ICM) is a component used with the IADDU and provides aircraft specific data to the IADDU, such as SSEC, Maximum Allowable Airspeed, Temperature Probe Type, Installation Configuration Display, LCD backlighting settings, analog output scale factor, and module software part number data.

The exact subtype of the configuration module depends upon the specific aircraft in which it will be installed. The module is connected to the aircraft using the lanyard provided.
