Control panel block diagram

2.2.1

Front Panel PCB

The Front Panel PCB contains the 7-segment displays for the pre-set ventila-
tion parameters, the drivers for the key LEDs, the drivers for interpretation of 
the keys and the shaft encoder, and the voltage generator for backlighting of 
the display. The voltage generation for the backlighting can be switched on 
and off from the control PCB.

2.2.2

Display

The display shows the patient parameters and the warning messages. The 
display is actuated by the Control PCB; the display backlighting is actuated 
by the Front Panel PCB. The display resolution is 240 x 128 pixels. The volt-
age supply is +5 V and -15 V.
