The digital core board also contains the interface circuitry that allows the RCP2-1000
RM to be firmware upgradeable in the field. A block diagram of the Digital Core Board
is shown in Figure 4-1.
4.2.2 I/O Board Assembly
The I/O Board Assembly contains the primary (hardware) interface circuitry of the con-
troller. It is physically attached to the Digital Core Board by two 40-pin headers. The
ten (10) Form C relays and opto isolated inputs for the parallel I/O interface are in-
cluded on this board assembly. The board also provides a physical connection be-
tween the liquid crystal display (LCD), front panel membrane keypad, and the Digital
Core Board.
4.2.3 Liquid Crystal Display
The RCP2-1000 RM provides a large 2 line by 40 character alphanumeric display. This
provides an extremely user friendly interface. The LCD is directly interfaced to the mi-
crocontroller via the address and data bus. Virtually all of the controller’s setup and ad-
justments are accessible from the LCD display. There is no need to access the interior
of the controller to make any setup changes.
4.2.4 Front Panel Membrane Keypad
The front panel membrane keypad is a densely integrated array of LEDs and switches
that comprise an important part of the user friendly interface. A great deal of human
engineering has gone into the design of this membrane panel. A full complement of
alarm indicators are provided along with the display. Four separate navigation buttons
along with a separate “Enter” button allow the user to easily navigate the firmware
menu on the Liquid Crystal Display. Separate buttons have been provided for fre-
quently used functions further enhancing the controller’s ease of use.
