Basic and Device CPSs contain a data
communications network controller and a power supply. The CPS/IDS
supplies power and communications interface for an SC 7000, SC 9000XL,
SC 9000, or SC6000 series patient monitor, and for peripheral devices
associated with the monitors. In addition they support two RS232 ports,
access to both CPS/IDS diagnostics and Host diagnostics, and support for
a passive remote display.
14.1Network Board
Hardware
The major circuits include a high speed serial link to the Patient Monitor,
control and status registers to the 68302 and 8344 processors, and
miscellaneous functions. The serial link functions as a bus master on the
local bus. The 68302 performs bus arbitration (and provides a serial
channel for communication with an SC6000). The registers and
miscellaneous func-tions are slave devices on the bus and completely
accessible to the 68302.

Motorola 68302 CPU
The Motorola 68302 CPU serves as the processing engine for the
SC6000 serial port link. The 68302 CPU runs at a frequency of
20MHz, and is connected to the CPS Bus. It accesses the FLASH (its
code space) and the 68302 External RAM (its data space) via the
CPS/IDS Bus.
FLASH memory is used for storage and execution of the 68302
software, and also to store care unit specific setups. The 68302
executes its code directly out of the FLASH, and is accessible from the
Bus to provide the ability to program it with new software from an SC
7000, SC 9000XL, or SC 9000 monitor.
Serial Communication Controller - User Interface
Note: The SCC also provides an SC 6000 series patient monitors link.
“SCC3” of the Motorola 68302 CPU provides a diagnostic user
interface, to run embedded diagnostics on the CPS/IDS hardware
and trace operations during software analysis and debugging
sessions. “SCC3” is used with a UART baud rate of 19.2K.
