2 FUNCTIONAL DESCRIPTION
2.1 Video Displays D-VMC15, D-VNC15, D-VHC17 and D-VSC21
The displays are suitable for high end applications using graphical interface. The adjustments and
selections are carried out through displays’ internal menus. The displays synchronize and adjust
automatically with a wide range of scanning frequencies.
The power supply section of the displays does not contain separating transformer, except D-VHC17
rev. 00-01 does. Therefore, the power for the other displays should be supplied via F-CU8 or via an
external separating transformer.
All the displays contain a degaussing (demagnetisation) circuitry. Degaussing takes place
automatically when the monitor is turned on, however, the degaussing can be activated also
manually during an operation, if necessary.
2.2 LCD display
NOTE: The LCD display backlight circuit runs on a high voltage. Do not touch the adapter board
when powered.
LCD Display, D-LCC10 includes LCD display module, LCD interface board, and keyboard. The
display keyboard works independent of the main keyboard.
LCD Display, D-LCC15 includes LCD display module and LCD interface board.
The LCD Display is connected to B-DISP Display controller board in the monitor frame with the LCD
display interface cable. The interface cable is available as an accessor y. See a ccessory catalogue.
Video signalling between the Display controller board B-DISP and the LCD Display takes place in
analog form. Incoming signals are buffered in the Interface board, converted into digital form, and
fed forward to the LCD Display module.
Communication between the Display controller board and the Command board takes place in
RS232 serial communication channel D.
NOTE: D-LCC10A/C and D-LCC15 require B-DISP.

Figure 1 General block diagram, D-LCC10A/C (rev. 01)
2.2.1 LCD interface board
The LCD Interface board is the interface between the display controller board and the LCD display
component. The keyboard is also connected to the Interface board, see figure 1.
The incoming signal to LCD Interface board is pure analog VGA - RGB with separate horizontal and
vertical synchronisation signals, see figure 2. The display element uses digital RGB-signals,
HSYNC, VSYNC, DOTCLK and a display timing signal DTMG. The DTMG signal indicates that the
digital RGB-signals are active.
The functions of this board are digitalization of the video signals, regeneration of the DOTCLK and
generation of the DTMG. The backlight driver is also located on the board.
Power supply, D-LCC10A/C
The DC/DC power supply is an isolated discontinuous mode flyback switcher. It has a current
mode PWM circuit and a separate FET switch on the primary side. The transformer has two
secondary windings, one for 5V and another for 12V. On the secondary side (5V), there is a
separate chip on the feedback path to drive the optoisolator.

2.4 Display Controller Board, B-DISP
B-DISP board is connected to the CPU Mother board. The processor on the CPU board transmits
program through the CPU bus to B-DISP board.
B-DISP board includes the functions of both B-DHIGH and B-DVGA boards. Thus, B-DISP board
supports both high resolution and VGA resolution. The resolution is automatically selected based
on monitor ID codes. The resolution is set to 640x480 if a VGA resolution display is used, otherwise
the resolution is set to 1984x512.
NOTE: S-ANE97/98/99, S-ICU97/98/99 and S(L)-ARK97/98/99 softwares support B-DISP, BDHIGH and B-DVGA boards. If, however, B-DISP board is used to drive D-VHC14 display, a small
part of the resulting picture will be clipped.
System memory
The system memory contains the GSP software code. The memory consists of two 256k x16
memory banks.
Frame memory
The frame memory contains digital display data. The size of the memory is 1 MB making 1984 x
512 display resolution with 256 colors possible. The memory consists of four 256k x 8 VRAM
memory circuits.
Displays and Controller Boards
Video interface palette
The video interface palette reads the digital display data from the frame memory and converts the
data into analog RGB-signals. The synchronization signals for the conversion are generated by the
GSP.
The video interface palette is clocked by two pixel clocks. A 25 MHz clock is selected for VGA
resolution and a 40 MHz clock is selected for high resolution. The 40 MHz clock is internally
converted into a 80 MHz clock.
Graphics System Processor (GSP)
There are four 16-bit registers in the GSP, from which the host-processor reads and to which it
writes data.
Display Controller Resolution
The resolution of the display controller depends on initialization of the GSP's registers and
frequency of the video oscillator.
Reset Signal
Reset signal comes from the power supply unit through the CPU bus.

S/5 Anesthesia Monitor and S/5 Critical Care Monitor
Monitor ID register
The monitor ID register contains a three bit (numeric values 0-7) monitor ID code. The register is
connected to channels 11-13 of the X3 D-connector. If no display is connected to B-DISP board or
if the monitor ID code fails, 111 code is generated by pull-up resistors. If the ID code is 011 or
101, VGA resolution is selected, otherwise high resolution is selected.
