TECHNICAL DESCRIPTION

4.1.1 Description

The purpose of the MMI board is to provide the Man Machine Interface between the
control card and the user.
The MMI board contains 5 LEDs for user diagnostics. It contains an LCD for displaying an
interactive menu, which is accessed via a control knob. An audio amplifier is provided to
drive a loud speaker at up to 2W, with volume adjustment via the control knob. An RJ45
interface for a serial port is also present.
The MMI board has a secondary function of providing the interface and drivers for the
fans.
Connection to the main control board is via a 14-way ribbon cable.
