MPC 860 has an embedded communications processor capable of
executing several protocols such as UART or Ethernet. The 860
communications channels are used as follows:
SCC1 Ethernet
SCC2 SC 9015 UART
SCC3 MVP-1 UART
SCC4 MVP-2 UART
SMC1 main diag UART
SPI a/d (power monitor)
SCC3 serial pod data
SCC4 serial pod data
SMC1 front end diag UART
An additional UART implemented in the FPGA contains a large FIFO and
interfaces to the chart recorder.
A CPS (communication, power supply) has three boards -- power supply,
network board, and connector board, and allows for connection to an
INFINITY network as well as MIB and CAN. The FPGA and main program
memory are downloadable by the SC 7000 and SC 9000XL. The power
supply is a medical grade universal supply operating from 88 to 264 vac.
The Docking Station is a passive device that serves as a sturdy mount for
SC 7000 and SC 9000XL (as well as SC 9000 and SC 6000 series patient
monitors), in support of the P
through signals between the monitor and the CPS.
The Infinity Docking Station base unit (IDS) with its separate power supply,
replaces the CPS and Docking Station combination in an I
N . As a docking station, it serves as a secure mount for the patient
ETWORK
monitors, as above, and also provides the network and peripheral device
connectivity of a Basic CPS. When equipped with a MIB 1-2 Option, it
provides the functionality of a Device CPS and Breakout Box.
The etCO cartridge is a hardware component attached to the back of the
2
SC7000 or SC 9000XL. The cartridge is a self contained computer capable
of mainstream and side stream measurements.
The external battery is a low cost lead acid battery and may be charged in
either the monitor or with an external charger. The external battery may be
hot-swapped to extend battery life during transport.
There are twelve fixed function keys on the monitor base unit, and a fixed
key dedicated as a power on/off switch. The power on/off switch is unique
in that it is not directly available via a status read command. The on/off
switch is input to the power supply subsystem interface, where the switch
state is detected and processed. Detection of a power off condition causes
an interrupt to the host processor.
The rotary knob is a 16 detent rotary knob. Each detent position indicates
a "click" clockwise or counter-clockwise. The change in detent position is
detected via a 2 bit quadrature code that changes value every time the
rotary knob is moved into a detent position. Also included in the rotary knob
is a push button switch that is operated by a press/release action. This
switch is used to select menu items on the screen.
