INTRODUCTION

Datex-Ohmeda S/5 UPI4NET board, B-UPI4NET integrates the UPI board and the Network Board,
B-NET. Datex-Ohmeda S/5 UPI4 board, B-UPI4 is the same board as UPI4NET except it does not
contain network related components.

The UPI4NET and UPI4 boards provide interfaces for example for a computer, parallel printer and
Device Interface Solution (DIS). In addition, the boards have two digital output signals and two
analog output signals for other interfaces.

The use of UPI4NET or UPI4 board requires S/5 Anesthesia or Critical Care main software.

2 FUNCTIONAL DESCRIPTION

2.1 General

2.1.1 UPI section

The UPI section functions as a general I/O-board. It performs I/O duties assigned to it by the CPU
board. The main processor in the CPU board and the processor in the UPI section communicate
through a dual-port memory which is located on the UPI4(NET) board.

Functional blocks

The UPI section contains the external bus interface, a processor, program- and dual-port memories
and I/O-block.

External bus interface

The UPI section is connected to the CPU mother board. The following signals pass on between the
UPI section and CPU mother board: data bus, address bus, reset, read and write signals, and other
related signals.

RS232 serial bus interfaces

RS232 serial bus is connected to the connector X8. That serial channel is driven by the CPU board.
Only the RS232 buffer and some filtering components are located in the UPI4(NET) board.

RS485 module bus interface

RS485 half-duplex communication bus for modules. Communication speed rate is 500 kbps.

RS422 DIS bus interface

RS422 full-duplex communication bus for DIS modules. Communication speed rate is 500 kbps.
DIS interface includes DIS power supply that gives voltages +8 V (max 1A) and +15 VD (max 1A).

2.1.2 NET section

The NET section is illustrated in a block diagram shown in figure 3.

The network interface controller is basically the heart of the NET section. The interface controller
communicates with the CPU board through the controller registers to the RAM. During the startup
sequence controller loads its address and some initializations from EEPROM.

The network interface controller transmits data packets to the S/5 Network and receives data
packets from the network through the 10BASE-T transformer. The transformer filters and transforms
the data and also provides the isolation.

The Ethernet status LEDs indicate the status of the network communication. The status LEDs are
controlled by the network controller. The LEDs are not visible when the board is installed into the
monitor.

The PLD interfaces the coding element. The coding element contains information on the monitor
location. The network address is transmitted to the CPU board through the network controller and
the monitor location information is transmitted to the CPU board through PLD interface.

2.2 Ethernet interfaces

The data transformer is designed by Datex-Ohmeda and it is hospital grade approved.

Adapter’s 10BASE-T is a interface with 7-pole butterworth low-pass filters on the unisolated side of
the transformer. On the isolated side there is a common mode choke for both transmitting and
receiving lines.

There are also three LEDs on the board, which are not seen from the outside, indicating the
following things:

- activity in Ethernet H1 Green

- collision detection H3 Yellow

- good link in 10BASE-T interface H2 Green

The activity LED (H1) flashes when communication packets are detected in the S/5 Network. The
collision detection LED (H3) indicates a packet collision on the network. The collision detection
LED should flash only occasionally, otherwise there may be a physical layer problem. The good link
LED (H2) indicates whether or not the communication link to the HUB is functional. The good link
LED should always be lit.
