CPU BUS
The CPU board, B-CPU4 is made with PC-technology components. Radisys chipset and PLD handle
all timings and signaling for ISA type CPU bus.
With B-CPU4 there is no external software cassette. Instead there is onboard flash memory where
software is loaded from the PC-card.
Powerfail or standby
When the monitor is turned to standby or the mains voltage fails, NMI-interrupt is generated by the
power control logic. The interrupt signal in the CPU means that all supply voltages except +5V for
the CPU board will be switched off shortly. NMI interrupt service program then saves all necessary
parameters in the static RAM before supply voltages fail.
When hardware detects HALT command generated from power down; all the outputs to the CPU
motherboard are left floating in high impedance state. Only DRAM refreshing cycle continues to
occur. The halt state will continue until a RESET pulse from the power control logic circuit is
received.

Watchdog functions
There are certain watchdog functions to ensure the monitor’s performance. The UPI4 board and the
primary display controller board interrupts the CPU board continuously in order to state that
everything runs smoothly. The CPU board refreshes the watchdog timer in the power supply unit in
order to prevent reset pulse. If the primary display controller board or the CPU board stops the
refreshment, the monitor will be reset in order to prevent false information to be displayed on the
screen. If the UPI4(NET) board stops the refreshment, the board will be reset internally.

Control logic
IO-decoding and wait state generation takes place in GAL IC and and in the processor. Code
memory (EPROM) and working RAM (DRAM) are designed to be linear, and static RAM and EPROM
are mapped in I/O space.
Wait state generators
The processor and the GAL IC have internal wait state generators for their predecoded chip select
pins. The wait state generator in the GAL IC is used also by the other boards connected to the CPU
bus.
Halt detection
NMI-interrupt is generated by the power control logic. The interrupt signal in the CPU means that all
supply voltages except +5V for the CPU board will be switched off shortly. NMI interrupt service
program then saves all necessary parameters in the static RAM before supply voltages fail.
When hardware detects HALT command all signals generated in the CPU board as well as all the
outputs to the CPU mother board are left floating in high impedance state; only DRAM refreshment
cycle continues to occur. The halt state will continue until a RESET pulse from the power control
logic circuit is received.

A service menu for showing information about internal
RS-485 and external RS-232 communication.
Module Bus (RS485) view shows information related to
the module bus.
UPI ints shows the number how many times the CPU
board has sent an interrupt to UPI board. The running
number should raise at a frequence of at least 100 Hz. If
the numbers don't raise there is trouble with the interrupt
line between CPU board and UPI board or with the boards
themselves.
The 10 ms tick shows how many 10 ms intervals the UPI
microprocessor has been on after last UPI reset. The UPI
microprocessor counts the 10 ms intervals. The number
must be running all the time at the frequency of 100 Hz. If
the number doesn't rise, the problem is in the UPI board.
Serial I/O (RS-232) view shows information about the
communication through the UPI board RS232 serial
connector X3.
Interface status shows whether the interface through the
connector is OPENED, ACTIVE or CLOSED. Opened
indicates that the hardware and software for the interface
is running but there is no connection or that there have
been errors in using the interface. Active indicates that
the interface is operating normally. Closed indicates that
the necessary hardware is not present.
Statistics In/Out show the numbers of received and
transmitted data packets and data bytes.
Rx errors show the number of received erroneous data
packets.

5.6 Set/Test
In the power supply unit, there is a safety element, which
needs refreshing at least every 1.5 seconds. If the main
CPU’s software will not refresh, safety element gives reset
to main CPU. In normal operation the main CPU’s
software refreshes safety element every 0.2 seconds.
The purpose of the safety element is to restart the monitor
if there is a serious malfunction. This feature is useful in
two cases: when the main CPU’s software is not able to
control the monitor, and when the software controls the
monitor but detects a serious malfunction. Watchdog
tests ensure the proper functionality of the safety
element’s various sections.
Watchdog test ensures directly that the watchdog of the
power unit functions properly. Choosing this test prevents
safety element from refreshing and shows running
seconds with an accuracy of 0.1 seconds.
The test should have the following result when the safety
element is working properly: The monitor will restart after
1.5 seconds from the start of the test. In malfunction:
‘>20 s’ is displayed, and the test will interrupt. In this
case, the fault is in the safety element of the power unit.
WD by Overload test ensures the functionality of a
feature, where the software controls the monitor, but
detects an overload situation in the main CPU.
The test should have the following result when the feature
is working properly: The monitor will restart after 15
seconds from the start of the test.
WD by UPI test ensures the functionality of a feature,
where the software controls the monitor, but detects a
malfunction in the UPI processor and restarts the
UPI4(NET) board. The test will prevent the UPI processor
from functioning during the test.
Immediately after the test starts the plotting stops. The
test should have the following result when the feature is
working properly: The monitor will restart the UPI4(NET)
board without any visual effects.
WD by GSP ensures the functionality of a feature, where
the software controls the monitor, but detects a
malfunction in GSP processor (located on the primary
display controller board) and performs a restart. The test
will prevent GSP processor from functioning during the
test.
Immediately after the test starts, the screen update
stops. The test should have the following result when the
feature is working properly: The monitor will restart after 5
seconds from the start of the test.
Factory Reset restore factory default settings and clear
data memories. Factory reset should be run if monitor
software is replaced or if the SRAM/Timekeeper IC, or its
battery is replaced.
