Memory Module, M-MEM

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 PCMCIA1 compatible 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 monitor location with the patient enabling continuous data collection. 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 monitors.

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

Module software runs under MS-DOS compatible operating system provided by Datalight . The files created in Data and Menu MemCards are MS-DOS compatible.

PCMCIA = Personal Computer Memory Card International Association MS-DOS is a trademark of Microsoft Corporation 3 Datalight is a trademark of Datalight, Inc. 2

The communication between the monitor CPU and the memory module is performed through highspeed internal TTL level RS-232 serial interface. Data transfer rate is 76.8 kbps. NOTE: Memory Module,M-MEM,cannot be used in the Extension Frame,F-EXT4 and in the S/5 Compact Monitors. NOTE: Memory Module, M-MEM rev. 00-02 require software upgrade for communication with S/5 Aneshtesia and Critical Care Monitors.

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. 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.

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.
