Description

The FDCCM43 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 customers needs. The front panel of the controller provides an area for an optional headphone jack. The FDCCM43 contains inputs and 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 four 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 FDCCM43 includes a microSD card for configuration updates. This card should be stored in a convenient location outside the device. Simply remove the FDCCM43 unit from its lower enclosure, exposing the microSD card slot.

The terminology “high side driver” is used to describe a driver which has a 28 volt output. The high side driver can be a continuous or momentary 28 volts when the driver is active. Typically, devices such as lights use high side drivers. “Low side driver” refers to a ground output. The ground output can be momentary or continuous when the low side driver is active. Commonly, devices such as window shades and lavatory flush devices use low side 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 “digital input” of the accessory interface node is an input which requires between 18V and 36V DC power to activate the input, and between 0V and 3V DC power to make the input inactive (voltages between the range of 3V and 18V are not a sufficient change to activate or deactivate the input). One type of digital input could be from a water level sensor, which may have a DC signal to activate the input. The firmware would read the input signal and display the correct indication on the control module.

The FDCCM43 has an optional headphone jack with a local volume control. The volume control 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 12 inch cable exiting the bottom of the display. The wires terminate with a free hanging D style male connector with backshell. The connector contains pins for power, power return (ground) and CAN Bus. It also has data input pins which read the status of external equipment and control output pins that take control of external equipment. External equipment can include lights, seat heaters, window shades, etc.
