The MDI Control Chassis panel containing the system controls and readout is referred to as the Control Chassis, a modular plug-in type device housing the main electronics of the system. This panel plugs into a heavy duty socket located in the main back-plate, mounted inside of the control enclosure. Preserving the modular design of this Control Chassis has simplified its usage and sustained its convenient attributes. Because all of the essential electronics are contained within this one unit, serviceability is as simple as unplugging one chassis and plugging in another.
