1.2.2 ESD precautionary procedures •
To avoid electrostatic charges building up, it is recommended to store, maintain and use 
the equipment at a relative humidity of 30% or greater. Floors should be covered by ESD 
dissipative carpets or similar. Non-synthetic clothing should be used when working with 
the component. 
•To prevent applying a possible electrostatic di scharge to the ESD sensitive parts of the 
equipment, one should touch the metallic fram e of the component or a large metal object 
located close to the equipment. When workin g with the equipment and specifically when 
the ESD sensitive parts of the equipment may be touched, a grounded antistatic 
wristband intended for use with ESD sensitive equipment should be worn. Refer to the 
documentation provided with the wristbands for details of proper use.
ESD precautionary procedure training
It is recommended that all potential users receive an explanation of the ESD warning symbol 
and training in ESD precautionary procedures. 
The minimum contents of an ESD precautionary procedure training should include an 
introduction to the phys ics of electrostatic charge, the voltage levels that can occur in normal 
practice and the damage that can be done to elec tronic components if they are touched by an 
operator who is electrostatically charged. Further, an explanation should be given of methods 
to prevent build-up of electrostatic charge and  how and why to discharge one’s body to earth 
or to the frame of the equipment or bond oneself by means of a wristband to the equipment or 
the earth prior to making a connection.

2 System description
2.1 Introduction
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.
2.2 Bus structure
The operation of Datex-Ohmeda FM is based  on two communication channels, the CPU bus 
and module bus. All units, including the module s, receive power from the same power supply, 
which is an integral part of the monitor frame.
Figure 2 General bus structure of S/5 FM 
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.

Document no. M1187317-009
The RS-485 type of serial communication su pports 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 advant age of this is that all bus connectors are 
identical and the modules can be connected in any order and position.
2.3 Distributed processing
A system assembled from Datex-Ohmeda products  is a multiprocessor system. All parameter 
modules have their own microprocessor, whic h 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 ma jor 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.
2.4 Module 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 comm unication 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.

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.
2.5 Software loading
The program memory on the CPU board is loaded  with monitor software at the factory. The 
software is used for running all the functions that are integrated into the PC board.
F-FM(W)-00
For service and upgrade procedures, the software loading is done by using a PCMCIA card or 
the SWDL Tool.
F-FM(W)-01
For service and upgrade procedures, the software loading is done by using the SWDL Tool only.

2.6 Parameter modules
Figure 4 General structure of parame ter 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 cons ists of buffers to interface the parameter 
module to the module bus while the rest of the el ectronics is located in the isolated section. The 
isolated section includes the microcontroller to gether with memory components, the front-end 
analog electronics (amplifiers, etc.) and sensor drivers.
