3.2.5 Keyboard
The keyboard is a standard 84 keyboard.
The keyboard layout may be changed by replacing the whole keyboard and selecting the
appropriate language in the firmware.
3.2.6 Operator display.
The operator display is a 240 pixel wide and 64 pixel high graphic liquid crystal display (LCD)
display with cold cathode fluorescent lamp back-light. The LCD is controlled by the micro-
processor on the CPU board. All characters are generated by the microprocessor and this
allows the Network ID Camera to show any character on the display in any size. Current
firmware provides 256 - 32 characters according to ISO 8859-1 in three sizes.
The back-light is driven by a high voltage and the generator (called inverter) that is located
as a small separate board on the CPU board. The life-length of the back-light is between
10,000 and 15,000 hours. Life-length is the number of hours the light can be on until the in-
tensity has decreased to half of the initial intensity. To extend the life length of the back-light
it will be switched off automatically when the camera has not been used for an hour and will
be switched on again as soon as a key on the keyboard is hit.
The LCD display is protected by a acrylic shield that can be replaced separately. It is not a
part of the LCD display but inserted between the LCD unit and the case.
3.2.7 Exposure unit.
The main parts of the exposure unit are the display, the lens and a mirror
The display is used to generate the picture that will be printed on the film. It is a 240 pixel
wide and 64 pixel high graphic liquid crystal display (LCD) display with cold cathode fluores-
cent lamp back-light, same type as the operator display. It is fully graphical which means
that any picture can be generated, the picture can be mirrored in any direction and the in-
formation can be printed either white on black or black on white.
The lens is a specially made for this camera. Both the sides of it has a convex lens and the
least convex side should face the display. The size of the picture on the film can be adjusted
by moving the lens backwards or forwards. This is though not recommended except in spe-
cial cases. On the market there are very few cassettes with a window which is shorter then
normal. For example there exists a mammography cassette where the window is located on
the short side and not on the long which is normal. Because of this there is no room to open
the window fully, instead the window is made about 25% shorter. To be able to use this cas-
sette with the Network ID Camera the lens has to be moved. It may also be necessary to put
