INTRODUCTION

The Memory Module, M-MEM is an optional data storage single width module designed for S/5
monitors. It is used for storing patient related physiological data, discrete record keeping events,
menu configurations and user defined monitor configurations in removable PCMCIA
memory cards.

The memory module can be utilized in the following applications:

• As a backup media for patient related physiological and record keeping data.

• As a local menu server for the monitor it is attached to.

• A memory card with its previously recorded patient data can be transported to a new

• To save and load user defined monitor configurations.

The memory module is available in one version:

• Single width external plug-in Memory Module, M-MEM for S/5 Critical Care and Anesthesia

The memory module has two card slots, which use rewritable PCMCIA-ATA specification
compatible memory cards: Data and Menu Cards.

The data card is used for storing patient related data and record keeping events, and the menu
card is used as a storage media for pre-recorded menu configurations and user defined monitor
configuration. If the module is used only for data backup and transportation, the Menu card is not
necessarily required. Similarly, if only record keeping configurations are needed, Data card does
not have to be present. In the latter case, however, no physiological or event data can be stored in
a memory card.

2 FUNCTIONAL DESCRIPTION

The Memory Module, M-MEM contains memory board and a LED (Light Emitting Diode) board
attached to the front panel.

The front panel has a dual PCMCIA card connector for two MemCards. Above the card slots there
are two push buttons for removing the MemCards from the module, and two memory card specific
LEDs. The LEDs are on during memory card read and write operations to notify the user not to
remove them until the operation is complete.

2.1 Memory Module, M-MEM

2.1.1 Memory board

Processor section

Basically, memory module is a single board PC with unnecessary I/O functions removed. The
processor is Intel 80C186 compatible and the software runs under DOS operating system.
Operating frequency is 16 MHz. The board has 512 kB RAM, 448 KB ROM, 128 kB EEPROM and
associated buffer circuits for memory operations.

Memory Module, M-MEM

Intel 82365SL compatible PC Card Interface Controller (PCIC) provides all the functions needed in
MemCard operations. Serial communication, EEPROM read and write operations and LED control
is accomplished through a QUART circuit. In addition, processor board contains circuitry to control
reset signals and MemCard programming voltages.

Memory module board block diagram is shown in figure 1.

PCMCIA card interface

MEM has PCMCIA compatible card sockets for two MemCards. Both sockets consist of 60 signal
and 8 power connections. MemCards are PCMCIA-ATA compatible, and their memory capacity
is 6 MB.

All MemCard read and write operations as well as card power management are controlled by PCIC
interface controller.
Card removals and insertions are also detected by the interface controller.
MemCard files are MS-DOS compatible and they can be copied for archival with any MS-DOS
compatible computer equipped with PCMCIA-ATA specification compatible card drive.

Memory Module, M-MEM

Serial communication

Serial communication between the module and main CPU board is done through module bus TTL­level RS-232 interface. Data transfer rate is 76.8 kbps.

RS485 type monitor reset signal is converted to module reset by an interface transceiver, and
power reset is generated by a reset circuit.

Power supply

Module receives its power (+5 V, +15 V) from the monitor. PCMCIA card programming
voltage +12 V is generated from +15 V by voltage regulators. Card programming voltage is
controlled by an interface controller. Otherwise, only +5 V power is used in the module. Maximum
power consumption is 2 W.

2.1.2 LED board

LED board contains only two yellow light emitting diodes and a three-lead cable to the memory
board.
