Master Controller
The master controller houses the windrower software and communicates with all other electrical modules on the
windrower.
The master controller is mounted behind the cab.
Extension Modules
Extension modules provide additional inputs and outputs for the master controller.
The M1170NT5 Windrower has two extension modules. One is
behind the cab, next to the master controller, and the other is
located inside the left frame rail. They are used to provide
inputs and outputs to various sensors and valve solenoids
throughout the windrower.
