Datex-Ohmeda S/5 Compact Anesthesia and Compact Critical Care Monitors
2System description
2.1Introduction
Datex-Ohmeda monitors build up a 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. This modular approach makes it possible to add new features when they are needed.

Figure 2General bus structure of S/5 system
The CPU bus is a communication channel used only for internal data transfer. It is based on the ISA
bus used in IBM PC computers. Data is transferred on this 16 bit wide bus using the CPU clock
frequency.
The module bus is for the parameter modules. The bus is based on the industry standard RS-485,
which uses a differential serial method to transfer data. This type of bus is robust and it allows
parameter modules to be inserted or removed while the power is on. The module bus uses a 500 kbps
data transfer rate.
The RS-485 type of serial communication supports so-called multidrop or party line connections. This
means that all parameter modules connected to the module bus use exactly the same lines for
communication. The advantage of this is that all bus connectors are identical and the modules can be
connected in any order and position.

Document no. M1031517-02
2.3Distributed processing
A system assembled from S/5 products is a multiprocessor system. All parameter modules have their
own microprocessor, which performs functions such as module key control, waveform filtering,
parameter related computing and pneumatic control, etc. At the same time the main CPU performs
higher level tasks such as trending and alarm control. While the parameter modules and CPU are
performing their tasks, the UPI (Universal Peripheral Interface) microprocessor handles all functions
needed to transfer data between the parameter modules and the CPU.
This kind of parallel processing gives one major advantage to centralized processing. When new
parameter modules are added to the system, the processing power is increased. As a result, the
system does not slow down when new features are added.
2.4Module communication
The communication master controlling data transfers between the CPU and parameter modules is
called UPI processor. It sends data to each connected module 100 times a second. Modules respond
to each data request immediately by sending a data package, whose length depends on the type of
the module. This communication protocol ensures that each module receives and sends data every
10 ms. If a module does not respond to data requests, the UPI processor presumes that the module is
disconnected.
Parameter modules may hold a static (fixed) or dynamic address, which the UPI processor uses when
sending out data. Two parameter modules of the same type must not be fitted onto the same monitor
since they might reply to a data request simultaneously, thus causing communication errors.

Figure 3Principle of UPI section operation
The UPI processor collects and stores all data that is received from the parameter modules into a
shared SRAM, which is mapped directly to the address space of the main CPU. The main CPU reads
data from the memory while the UPI processor guarantees that the data is up to date. This operation
also works in the other direction. In this the main CPU fills the shared SRAM with data and the UPI
processor distributes it to the parameter modules.

Figure 4General structure of parameter modules with patient isolation
The detailed structure of a parameter module depends on the specific needs for each individual
parameter. However, some common parts are used in the parameter modules. The electronics inside
the module is usually divided into isolated (floating) and non-isolated sections. Typically, the
non-isolated section consists of buffers to interface the parameter module to the module bus while
the rest of the electronics is located in the isolated section. The isolated section includes the
microcontroller together with memory components, the front-end analog electronics (amplifiers, etc.)
and sensor drivers.
