General Information

The Model 69440-001 Master Control Unit (MCU) is the central component of SmartSeries system
operations, processing all operations through its associated system software. It is installed in the 10457
Card Rack Assembly and maintains constant communication with all other SmartSeries devices installed
in the card rack and the system.

The MCU constantly supervises operations to ensure proper working condition. It is exclusively designed
for use in a SmartSeries system; the MCU is not intended for use with other types of equipment.

CAUTION

personnel unless explic itly stat ed otherw is e in your system manual.

Connections to the MCU are reserved for use by authorized factory-t rained

Description of Major Compo nents

MCU Front Panel LEDs

The LED Array provid es sta tus on i nternal opera tion of the MCU. Ab breviat e d text labels to the right of
the LEDs help to locate a particular LED. Both the LEDs and their labels are divided into two columns;
the left column of labels corresponds to the left column of LEDs; the right column of labels corresponds
to the right column of LEDs.

These LEDs a re ON, t hey have the following m ean ings:

LED Description (When ON)

-12V
+12V
+5V

The card rack is providing –12 volts dc to the MCU.
The card rack is providing +12 volts dc to the MCU.
The card rack is providi n g +5 volts dc t o the MCU.

BEEP This LED simulates the CPU module speaker function. The LED emits light instead of a

speaker emitting sound..

N

OTE 1: The LED flashes ON briefly when the PC begins booting, otherwise, this LED

is OFF. If applicable, your system manual lists situations where this LED should be ON.

N

OTE 2: If the CPU Module detects an error during boot-up, this LED will flash more

than once. In this error condition, the CPU Module generates, a one-time “beep code” to
aid in diagnosing the fault. Momentarily pressing the reset button will cause the beep
code to repeat.

LINK Shows Ethernet network status. The MCU has established a communications link with

another Ethernet network device.

ACT Shows Ethernet network status. The MCU detects activity on the attached Ethernet

cable.

BP

The MCU is using the data bus in the card rack.
The card rack is sometimes referred to as “back plane,” which gives this LED its

abbreviation (BP).

SPD This LED operates in conjunction with LINK LED to indicate the speed of the Ethernet

network connection.

(On) SPD (Off) = 10 M B Ether net connection

LINK
LINK

(On) SPD (On) = 100 MB Ethernet connection

LINK

(Off) SPD (On) = no networ k c onnection est ablishe d

SEC The MCU is accessing the Compact Flash card connected to the secondary IDE

controller.

PRI
B7, B6, B5,

B4,

B3, B2,
or B0

B1,

The MCU is accessing the hard disk drive connected to the primary IDE controller.
These LEDS are r eferred to as the Po rt 8 0 LEDS. They are used to show diagnostic

inf ormation that can be used by f actory train e d technicians as a tr oubleshootin g aid.

MCU Front Panel Connections

The PS/2 keyboard and PS/2 mouse connectors enable connecting a PS/2 keyboard and a PS/2 mouse,
respectively, to the MCU. These connectors are color-coded to match the PC99 standard. In order for the
mouse to function properly, it must be connected at power-up.

The COM2 RS232 port provides a RS232 serial connection to the MCU. This connector’s pin-out
matches t hat of a standard PC ’s 9-p in seri al connector pin- out.

OTE: The COM2 RS232 port is logically in parallel with the COM2 RS485 half-duplex port on the rear

N

of the card rack; therefore, both of the ports may not be used simultaneously.

The VGA conn ector enabl es conn ect ing a VGA monito r to the MCU. This connector is co l or co d ed to
match the PC99 sta ndard.

The USB Port 0 and USB Port 1 connectors enable connecting USB 1.0 devices to the MCU.
The Reset button resets the MCU. Momentarily depress the RESET button to reset and re-boot the

MCU. Holding in the R

ESET button will keep the MCU in reset mode, and it will not re-boot. The

button is recessed to prevent accidental depressions.

Card Rack Rear Panel Connections

The LPT1 parallel port provides a parallel port connection to the MCU. This is typically used for
connecting a printer. This connector’s pin-out matches that of a standard PC’s 25-pin parallel port
connector pin-out.

The COM1 RS485 half-duplex port provides a half-duplex RS485 connection to the MCU. This
connector’s pin- out is prop rietary. Also, this co nnection provides a dry conta c t closur e ou tput. If
applicable, the operation of this connector is described in your system manual.

N

OTE: The COM2 RS232 port is logically in parallel with the COM2 RS485 half-duplex port on the

front panel of the MCU; therefore, both of the ports may not be used simultaneously.

MCU Internal Connections

The CPU Module holds the microprocessor that controls the system.

The Ethernet port provides an Ethernet connection to the CPU Module.
The battery allows the CPU Module to keep track of the date and time in the event of a power failure.

OTE: CMOS settings are stored in EEPROM; their storage does not rely on battery power during a

N

power failure.

A 2.5-inch IDE Hard Drive connects to the CPU Module. The 2.5-inch ID E hard dri ve is format ted and
proper software is f act ory ins talled.

A CompactFlash Card connects to the CPU Module. The Comp act Flash car d is formatted and proper
software is factory-installe d.

The Upper VME Connectors provides the mechanical connection to the card rack’s backplane.

The Lower VME Connector provides the mechanical connection to the rear panel of the card rack. used
for connection of external devices described above under Card Rack Rear Panel Connections section.
