The FDCCM3 is a three OLED display with overlaying mechanical feather-touch buttons and
two menu navigation buttons. Both models control the reading light, the table light, window
shades, and the entertainment audio and video for that one seat. The FDCCM3 also may
be programmed with sub-menus which may control a designated area of the cabin. The
menu is highly configurable and allows for complete control of designated equipment for an
aircraft.

The FDCCM3 and FDCCM3-A consist of three OLED displays with three mechanical
switches. It has CAN, RS-485 and RS-232 computer interfaces. Four high side outputs, two
low side outputs and two digital inputs are available. The high side switches have a 2 Amp
source output, and the low side switches have a 2 Amp sink output.

Switch actions may be configured to support a myriad of behaviors: Low side switches may
be enabled or disabled. A button press can send a message out on both the high and low
side switches. A held button press can trigger separate commands from a button press. A
timed output can be on a scale of hours (with a 1 minute resolution) or on a scale of minutes
(with a 1 second resolution). Outputs can be in CAN/485 protocols and send out more than
one message per button press.

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 FDCCM3-A display has local volume control. The volume control has 32 steps. It is
controlled by the volume up/down control buttons.

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
control external equipment such as lights, seat heaters, window shades, etc.
