The FDCCM30 consists of a color, high resolution liquid crystal display and touchscreen overlay. The firmware creates a multi level button based menu system fully customized based on the customer’s needs. The front panel of the controller provides an area for an optional headphone jack.
The FDCCM30 contains outputs primarily intended to control items located in close proximity (<2 meters) to the CCM. It has CAN, RS-485 and RS-232 computer interfaces. It has two high side outputs and two low side outputs, which are under computer control. The high side switches have a 2 amp source output, and the low side switches have a 2 amp sink output. Like the FDCCM3, the FDCCM30 includes a microSD card for configuration updates. Simply remove the top cover of the FDCCM30 to expose the microSD card slot.
The terminology “high side driver” is used to describe a driver which has a 28 volt output. These can be a continuous or momentary 28 volts when active. Typically, devices such as lights use these drivers. “Low side driver” refers to a ground output. These can be momentary or continuous when active. Commonly, devices such as window shades and lavatory flush devices use these drivers. A low side driver would provide a momentary ground for a flush or a constant ground to move a window shade up or down.
The FDCCM30 has an optional headphone jack with a local volume control. The volume control typically has 32 steps. It is controlled by a volume control icon on the touchscreen. Cabin speaker control may also be selected.
Electrical connections to the display are established via a 20 pin male connector on the bottom of the display. The connector contains pins for power, power return (ground) and CAN bus. It also has control output pins that take control of external equipment. External equipment can include lights, seat heaters, window shades, etc.
