2 SYSTEM DESCRIPTION
2.1 Introduction
Datex-OhmedaAS/3 and CS/3 monitors builds up to freely configurable modular system. The
architecture is designed to enable different module combinations so that the user is able to get the
desirable parameter and feature set. The modular approach makes it possible to add new features
when they are needed.
2.2 Bus structure
The operation of Datex-OhmedaAS/3 and CS/3 products is based on two communication
channels, the CPU bus and the module bus. All boards connected to the CPU bus as well as the
parameter modules attached to the module bus receive their power from the same power supply,
which is an integral part of the frame.
General Service Guide
UPI /
UPINET
CPU BUS
MODULE BUS
Figure 2General Structure of AS/3 and CS/3 System
The CPU bus is a parallel communication channel used only for internal data transfer between the
boards connected to one frame. It is based on the ISA bus used in the IBM PC computers. Data is
transferred on this 16 bits wide bus using the CPU clock frequency.
The module bus is used to connect the parameter modules to the frame. It based on the widely
used industry standard RS-485, which uses differential serial method to transfer the data. This
type of bus is quite robust and it allows the modules to be attached or detached when the power is
on.
The RS-485 type serial communication supports so called multidrop or party line connections. This
means that all modules connected to module bus are using the same two physical wires for
communication purposes. The advantage is, that all the module bus connectors are identical and
the modules can be connected to any order and position.

Display
Controller
Parameter

Power
Supply
Module bus is using 500 kbps data transfer rate and it can be used for longer distances than the
CPU bus, e.g. for external-frame connections.
A system put together from AS/3 and CS/3 products is a multiprocessor system. All the modules
have their own microprocessor and they are doing the low-level functions such as module key
control, waveform filtering, pneumatic control, etc. At the same time the main CPU is doing higher
level tasks, e.g. trending and alarm control. While modules and CPU are doing their job, the UPI
processor takes care of all functions needed to transfer the data between modules and CPU. And
at the same time the processor on display control board is doing pixel calculations for graphics.
This kind of parallel processing gives one major advantage to centralized processing. Each time
new modules or boards are added to the system, the processing power is also increased. As a
result the system is not slowing down when new features are added.

2.4Module communication
A
s
The communication master controlling the data transfer between CPU bus and module bus is
called UPI (Universal Peripheral Interface) board. It sends information or questions to each module
100 times per second, and if the module is present it replies to each question immediately by
sending a data package back to UPI board. This communication protocol ensures that each
module receives and sends information every 10 ms, the package length depends on the module
type. If the module does not respond, the UPI presumes that the module is not connected.
Each module type has a unique name, which UPI uses to address its messages. If there are two
modules of the same type, they both answer at the same time. This results an error and thus two
similar modules are not allowed in one frame.

RAM
Microcontroller
Figure 4Principle of UPI operation
The microprocessor on the UPI board collects all information coming from the modules into a dualport RAM. This memory is located on UPI board and it is mapped directly to the address space of
the main CPU. The main CPU is thus reading information from it's own memory and UPI guarantees
that the data is up to date. This operation works also to the other direction, when CPU is filling the
dual port RAM with data and UPIs’ microprocessor is distributing it to the modules.
The Software Cartridge attached to the B-CPU2/3 board contains the program for the CPU board
as well as for some other boards attached to the CPU bus. When the system is turned on, all
processors load their part of the software from the cartridge and after that start to execute their
program.
The CPU Board, B-CMCPU4 contains no external software cartridge. The softwares are always
loaded on the B-CMCPU4 boards already at the factory. For service procedures B-CMCPU4 boards
has a PC card drive, through which the software is loaded permanently on the board from the
software card.

2.6 Parameter modules
The detailed structure of the parameter modules depends on the specific needs for each individual
parameter. Some common parts can be found inside the modules, however. The electronics inside
the module is usually divided into isolated (floating) and non-isolated sections. Typically the nonisolated part consists only buffers needed to interface the module to module bus, the rest of the
electronics can be found from the isolated side. This includes the microcontroller together with
memory components, the front end analog electronics (amplifiers, etc.) and peripheral drivers to
control LEDs, sensors, valves and pumps.

the low state. The high state ranges from 2.8 to 5 V while the low state ranges from 0 to 0.8 V. The
delay from the R wave peak to the start of the signal is maximally 35 ms.
Nurse Call
The nurse call signal is generated by red, yellow and white alarms. When activated, the signal is set
to a high state and remains at a high state until the alarm situation is over or the Silence Alarm
key is pressed. The high state ranges from 2.8 to 5 V while the low state ranges from 0 to 0.8 V.
Pacemaker Sync
The pacemaker sync signal is generated by pacemaker pulses on the ECG. When activated, the
signal is set to a high state and then set back to a low state such that the signal pulse width is
between 0.5 to 2.5 ms. The high state ranges from 2.8 to 5 V while the low state ranges from 0 to
0.8 V.
