Oil-Less Claw Medical Vacuum
Appendix A: TotalAlert Embedded Control System
A.1 Board Confi gurations
The source control system is comprised of four
(4) diff erent printed circuit boards (PCBs) with
interconnecting wiring (RS485 or Ethernet) for
internal communications between the boards.
See Figure A.2.
1. PCB1: Display Board for 5.7” Touch Screen
Display
2. PCB2: Display Board for 3.5” Touch Screen
Display
3. PCB3: Master Source Controller Board
4. PCB4: Pump Controller Board
In a standard medical vacuum duplex system,
the PCB confi guration consists of the following
quantities and types of boards:
• PCB1 – (1) One for the Main 5.7” display
• PCB2 – (2) One for each of the Unit 3.5”
displays
• PCB3 – (1) Master Controller
• PCB4 – (2) One for each pump
In a standard medical vacuum quadruplex system,
the PCB confi guration consists of the following
quantities and types of boards:
• PCB1 – (1) One for the Main 5.7” display
• PCB2 – (4) One for each of the Unit 3.5”
displays
• PCB3 – (1) Master Controller
• PCB4 – (4) One for each pump

A.2 PCB1 (5.7” Display Controller)
A.2.1 Basic Software Architecture
The primary purpose of PCB1 is to drive the LCD
display for the 5.7” Master screen. Its other
functions include the following:
1. Communicate to the Master Controller Board
(PCB3) via a RS-485 bus to relay commands
from the touch screen interface and display
messages from the master controller.
2. Interface to the 5.7” Display touch screen to
interpret the user interaction.
3. Drive the 24VDC local alarm horn when
signaled by the master controller via the RS485
bus.
4. Read the input from the motion detector at the
front panel and relay the status to the master
controller so it can distribute the information
to the other pump controllers and then to their
corresponding 3.5” display boards (PCB2).
5. Accept new fi rmware via the Ethernet jack when
connected to a PC confi gured with genuine
BeaconMedæs software for reprogramming.
