S/5 UPI(NET) Board, B-UPI4(NET)

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.

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. S5 module bus

UPI section block diagram

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.

Processor The processor in the UPI section is an H8S/2655, which functions at 16 MHz frequency. 3 Document No. 800 1022-1

Datex-Ohmeda S/5 AM and S/5 CCM

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. JTAG

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.

Nurse Call (pin 8) The nurse call signal is generated by the red, yellow and white alarms. When activated, the signal is set to the high state and remains at the high state until the alarm situation is over or the SILENCE ALARM key is pressed. The high state range is from 2.8 to 5 V, while the low state range is from 0 to 0.8 V. If the output signals are used simultaneously with the coding element, the B-UPINET Y-cable, order number 889308, is recommended to be used.

SERVICE PROCEDURES Due to the nature of the UPI4(NET) board, field service is limited only for troubleshooting. Faulty UPI4(NET) boards are returned to Datex-Ohmeda for repair. Datex-Ohmeda is always available for service advice. Please provide the unit serial number, full type designation and a detailed description of the fault.

CAUTION

Only trained personnel with appropriate tools and equipment are allowed to perform the tests and repairs outlined in this section. Unauthorized service may void warranty of the unit.

3.1 Service check for the NET section These instructions include complete procedures for a service check for the UPI4(NET) board. The service check is recommended to be performed after any service repair. However, the service check procedures can also be used for determining possible failures. The procedures should be performed in ascending order. The instructions include a check form (Appendix A) which should be filled in when performing the procedures. The mark

? in the instructions means that the check form should be signed after performing

the procedure.

The procedures are designed for monitors with S/5 monitor software of revision 01. However, most of the procedures also apply to monitors, which contain some other monitor software type/revision.
