The
PC
Board is the “master” controller board of the machine. It is a Mini-
ITX
board running the Linux
operating system, and it is located in the
RVM
Controller Box. It runs these software processes: The
Main Control Process, the Diagnostic Program, the Printer Process, the Display Process, and the Hard-
ware Process.
1.
Main Control Process
This process is the “master” process that directs all of the other processes. It also communicates
with the Scanner Multiplexer (
MUX
) board that controls and coordinates the six barcode scan-
ners in the feed unit.
2.
Display Process
The Display Process communicates with the display.
3.
Printer Process
The Printer Process communicates with the printer.
4.
Hardware Process
The Hardware Process directs all of the other hardware in the
RVM
, through the use of custom
controller boards. The Hardware Process translates all of the commands of the Main Control
Process into signals that can be read by these subordinate controller boards. These signals are
conveyed through an
RS
-485 serial connection, using the Multidrop Bus Protocol (
MDB
). The
subordinate boards are
MC
1,
MC
5, and
MD
5. M
C
1 controls the hardware that is common to
all versions of the
ULTRA
series: the safety interlock and the compactors. M
C
5 and
MD
5 work
together to control all of the hardware that is common to the
ULTRA
48 machines: the In-Feed,
the Sorting Cylinder, and the receipt button.
