Figure 2 CPU board block diagram, B-CPU5/B-CPU4

The CPU board, B-CPU5/B-CPU4 is made with PC-technology components. Radisys chipset and

PLD handle all timings and signaling for ISA type CPU bus.

The B-CPU5/B-CPU4 contains an onboard flash memory where software is downloaded from a

software 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(NET) board

and the primary display controller board interrupt the CPU board continuously in order to state that

they function properly. 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.

SRAM M48T18

Lithium battery back-up 8 kB static RAM with a real-time clock.

CAUTION The IC contains a lithium battery. Discard the battery according

to local regulations.

2.2 Software Cards, U-xxxxxx/L-xxxxxxS/S-xxxxxS

Upgrade software, U-xxxxxx and Service software, L-xxxxxxS/S-xxxxxS are delivered on an 8 MB/4

MB PCMCIA flash memory card.

The upgrade software has been developed for monitor software upgrades. The uprgade software

can be downloaded onto a monitor that is equipped with the B-CPU5/B-CPU4.

The service software has been developed to replace the original monitor software in case of a B-

CPU5/B-CPU4 failure. The service software is downloaded onto a replacement empty B-CPU5/B-

CPU4. See section 3.3.1 “Downloading/replacing software on CPU Board, B-CPU.””

There is service software available of each S/5 monitor software version. The functionality of the

service software is equal to the functionality of the corresponding original S/5 monitor software.

The Service software, L-xxxxxxS is license software. The license agreement that is delivered with the

software should be archived in a secure location. Relevant license number may have to be referred

when contacting Datex-Ohmeda for service/support. The licence number is needed also for

possible software upgrades.

CAUTION The software card is not write-protected. For safety reasons do not use software

cards in any other purposes, or on any other platforms than they are designed for.
