Revision A
DASH 2000 Patient Monitor
4-21
2000 412-001
Processor PCB
Symptoms
Symptoms with network communications, asynchronous
communications, NBP control, analog output, audio/sound generation,
and remote video signals/communications as well as other display-related
problems all may be associated with processor PCB failure. All of these are
functions controlled by microcontroller or graphics processing circuitry
located on the processor PCB.
Power Supply PCB
Symptoms
The power supply provides power that is used throughout the DASH
monitor. The supply voltages are generated for various applications on
the PCB Mainboard out of the +9 to +18 regulated VDC voltage. Below is
a list of the supply voltages and where and how these voltages are
applied. Problems in any of the following areas may be associated with
power supply failure.
+9 to +18 VDC
